## Background
PRIORITY DATA
The present application is a utility application of provisional U.S. Patent Application No. 61/697,151, filed on Sep. 5, 2012, entitled “Predefined Input for Clinician Programmer Data Entry,” the disclosures of each of which are hereby incorporated by reference in their entirety.
BACKGROUND
As medical device technologies continue to evolve, active implanted medical devices have gained increasing popularity in the medical field. For example, one type of implanted medical device includes neurostimulator devices, which are battery-powered or battery-less devices that are designed to deliver electrical stimulation to a patient. Through proper electrical stimulation, the neurostimulator devices can provide pain relief for patients or restore bodily functions.
Implanted medical devices (for example a neurostimulator) can be controlled using an electronic programming device such as a clinician programmer or a patient programmer. These programmers can be used by medical personnel or the patient to define the particular electrical stimulation therapy to be delivered to a target area of the patient's body, alter one or more parameters of the electrical stimulation therapy, or otherwise conduct communications with a patient. However, data entry on existing programmers has been slow and inefficient. Users typically have to enter data manually by typing in each character one by one, either through a virtual keyboard or a physical one. This slow and inefficient data entry process is not only frustrating for the user, but it also greatly increases the likelihood of errors occurring during the data entry process.
Therefore, although existing neurostimulation devices and methods have been generally adequate for their intended purposes, they have not been entirely satisfactory in every aspect.
SUMMARY
One aspect of the present disclosure involves a portable electronic device configured to program stimulation parameters of an electrical stimulation therapy for a patient. The portable electronic device includes: a touch-sensitive user interface configured to receive an input from a user and display an output to the user; a memory storage configured to store programming instructions; one or more electronic processors configured to execute the programming instructions to perform the following steps: receiving, via the touch-sensitive user interface, a request from a healthcare professional to perform data entry in an input field; displaying, via the touch-sensitive user interface and in response to the receiving the request, a plurality of predefined suggestions as candidates for the data entry, wherein the predefined suggestions are customized for one of: the healthcare professional or the patient; detecting, via the touch-sensitive user interface, a selection of one of the plurality of predefined suggestions by the healthcare professional; and automatically entering the selected predefined suggestion as the data entry in the input field.
Another aspect of the present disclosure involves a medical system. The medical system includes: one or more medical devices configurable to deliver a medical therapy to a patient; and a portable electronic device having a touch-sensitive user interface through which data entry is performed with respect to the medical therapy, wherein the portable electronic device includes a non-transitory computer readable medium comprising executable instructions that when executed by a processor, causes the processor to perform the steps of: receiving, via the touch-sensitive user interface, a request from a healthcare professional to perform data entry in an input field; displaying, via the touch-sensitive user interface and in response to the receiving the request, a plurality of predefined suggestions as candidates for the data entry, wherein the predefined suggestions are customized for one of: the healthcare professional or the patient; detecting, via the touch-sensitive user interface, a selection of one of the plurality of predefined suggestions by the healthcare professional; and automatically entering the selected predefined suggestion as the data entry in the input field.
Yet another aspect of the present disclosure involves a method of entering data in a portable electronic device. The method includes: receiving, via a touch-sensitive user interface of the portable electronic device, a request from a healthcare professional to perform data entry in an input field; displaying, via the touch-sensitive user interface and in response to the receiving the request, a plurality of predefined suggestions as candidates for the data entry, wherein the predefined suggestions are customized for one of: the healthcare professional or the patient; detecting, via the touch-sensitive user interface, a selection of one of the plurality of predefined suggestions by the healthcare professional; and automatically entering the selected predefined suggestion as the data entry in the input field.
One more aspect of the present disclosure involves an apparatus for inputting data in a clinician programmer. The apparatus includes: means for receiving a request from a healthcare professional to perform data entry directed to a patient file in an input field; means for displaying a plurality of predefined suggestions as candidates for the data entry, wherein the predefined suggestions are customized for one of: the healthcare professional or the patient, and wherein the displaying comprises: assigning a respective rank to each of the plurality of predefined suggestions according to one or more predetermined criteria, and displaying the plurality of predefined suggestions according to their respective ranks, wherein the predetermined criteria include at least one of: frequency of past use of each of the predefined suggestions, and correlation between each of the predefined suggestions and an existing data content in the patient file; means for detecting a selection of one of the plurality of predefined suggestions by the healthcare professional; and means for automatically entering the selected predefined suggestion as the data entry in the input field.

DETAILED DESCRIPTION
It is to be understood that the following disclosure provides many different embodiments, or examples, for implementing different features of the invention. Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. Various features may be arbitrarily drawn in different scales for simplicity and clarity.
The use of active implanted medical devices has become increasingly prevalent over time. Some of these implanted medical devices include neurostimulator (also referred to as a pulse generator) devices that are capable of providing pain relief by delivering electrical stimulation to a patient. In that regards, electronic programmers have been used to configure or program these neurostimulators (or other types of suitable active implanted medical devices) so that they can be operated in a certain manner. These electronic programmers include clinician programmers and patient programmers, each of which may be a handheld device. For example, a clinician programmer allows a medical professional (e.g., a doctor or a nurse) to define the particular electrical stimulation therapy to be delivered to a target area of the patient's body, while a patient programmer allows a patient to alter one or more parameters of the electrical stimulation therapy.
In recent years, these electronic programmers have achieved significant improvements, for example, improvements in size, power consumption, lifetime, and ease of use. However, in spite of the numerous improvements in various areas, existing electronic programmers still have significant shortcomings with respect to data entry. For many existing programmers, data entry consists of a user manually typing in characters via a virtual keyboard of the electronic programmer. As such, existing electronic programmers suffer from the following drawbacks:

    
    
        Healthcare professionals waste time typing out information character by character.
        Common neural stimulation words and phrases must be re-entered every time they are used.
        Paragraphs for standard procedural records, common symptoms, etc. must be re-entered frequently.
        Errors in data entry are increased, a factor that slows down or prevents searchability and potentially creates misleading electronic medical records of patients.
        If a stylus is missing, information input is impossible.
    
    


To address these drawbacks discussed above, the present disclosure offers a method and system of implementing predefined inputs for programmer data entry, as discussed below in more detail.
FIG. 1 is a simplified block diagram of a medical device system 20 is illustrated to provide an example context of the various aspects of the present disclosure. The medical system 20 includes an implantable medical device 30, an external charger 40, a patient programmer 50, and a clinician programmer 60. The implantable medical device 30 can be implanted in a patient's body tissue. In the illustrated embodiment, the implantable medical device 30 includes an implanted pulse generator (IPG) 70 that is coupled to one end of an implanted lead 75. The other end of the implanted lead 75 includes multiple electrode surfaces 80 through which electrical current is applied to a desired part of a body tissue of a patient. The implanted lead 75 incorporates electrical conductors to provide a path for that current to travel to the body tissue from the IPG 70. Although only one implanted lead 75 is shown in FIG. 1, it is understood that a plurality of implanted leads may be attached to the IPG 70.
Although an IPG is used here as an example, it is understood that the various aspects of the present disclosure apply to an external pulse generator (EPG) as well. An EPG is intended to be worn externally to the patient's body. The EPG connects to one end (referred to as a connection end) of one or more percutaneous, or skin-penetrating, leads. The other end (referred to as a stimulating end) of the percutaneous lead is implanted within the body and incorporates multiple electrode surfaces analogous in function and use to those of an implanted lead.
The external charger 40 of the medical device system 20 provides electrical power to the IPG 70. The electrical power may be delivered through a charging coil 90. In some embodiments, the charging coil can also be an internal component of the external charger 40. The IPG 70 may also incorporate power-storage components such as a battery or capacitor so that it may be powered independently of the external charger 40 for a period of time, for example from a day to a month, depending on the power requirements of the therapeutic electrical stimulation delivered by the IPG.
The patient programmer 50 and the clinician programmer 60 may be portable handheld devices that can be used to configure the IPG 70 so that the IPG 70 can operate in a certain way. The patient programmer 50 is used by the patient in whom the IPG 70 is implanted. The patient may adjust the parameters of the stimulation, such as by selecting a program, changing its amplitude, frequency, and other parameters, and by turning stimulation on and off. The clinician programmer 60 is used by a medical personnel to configure the other system components and to adjust stimulation parameters that the patient is not permitted to control, such as by setting up stimulation programs among which the patient may choose, selecting the active set of electrode surfaces in a given program, and by setting upper and lower limits for the patient's adjustments of amplitude, frequency, and other parameters.
In the embodiments discussed below, the clinician programmer 60 is used as an example of the electronic programmer. However, it is understood that the electronic programmer may also be the patient programmer 50 or other touch screen programming devices (such as smart-phones or tablet computers) in other embodiments.
FIGS. 2-4 illustrate an embodiment of a user interface 100 implemented on an example clinician programmer 60. Specifically, the portions of the user interface 100 shown in FIGS. 2-4 illustrate the presentation of predefined data entries (or preset responses) according to the various aspects of the present disclosure. In some embodiments, the user interface 100 may be displayed on a screen of a programmer, for example a capacitive or resistive touch-sensitive display. In other embodiments, the user interface 100 may be displayed on a programmer and an external monitor simultaneously, for example in accordance with U.S. patent application Ser. No. 13/600,875, filed on Aug. 31, 2012, entitled “Clinician Programming System and Method”, the disclosure of which is hereby incorporated by reference in its entirety. As such, both the healthcare provider (e.g., the target user of the user interface 100) and the patient are able to view the user interface 100 at the same time.
Referring to FIG. 2, the user interface 100 allows a user (e.g., a healthcare professional) to perform data entry for a patient file. The patient file may include a variety of information related to the patient and/or the treatment for the patient, such as the patient's name, address, occupation, gender, ethnicity, past medical history, current treatment plans, etc. In the example shown in FIG. 2, the user interface 100 illustrates an example programming screen for programming stimulation parameters for an electrical stimulation therapy to be delivered to a patient, for example by the IPG 70 of FIG. 1. As examples, these stimulation parameters may include stimulation current, pulse width, frequency, and electrode polarity or configuration. A programmed group of stimulation parameters and/or other programmable details collectively corresponds to a “stimulation program.” In the user interface 100 shown in FIG. 2, the stimulation program has a default name of “Program 1.” However, this default name for the stimulation program may not be sufficiently descriptive. As such, the user (e.g., a healthcare professional) may wish to change the name “Program 1” to another more descriptive name. As discussed above, existing electronic programmers typically require the user to manually type in a new program name character by character, which is inefficient and error-prone.
According to the various aspects of the present disclosure, the user interface 100 of the clinician programmer 60 allows suitable or appropriate program names to be automatically suggested. Referring to FIG. 3, when the user clicks on the program name “Program 1”, a text input field 110 appears. The input field 110 is accompanied by a virtual keyboard in the illustrated embodiment, but it is understood that other suitable input devices may be used in other embodiments, such as a physical keyboard. The user may edit the program name (for example by using the virtual keyboard) in the input field 110.
To facilitate the editing of the program name, the user interface 100 also displays a list of suggested program names 120. In the illustrated embodiment, the suggested program names 120 are displayed as a drop-down list adjacent to the input field 110. In other embodiments, the suggested program names 120 may be displayed as a list of suggestions floating above the specific data entry field. As examples shown in FIG. 4, the list of suggested program names 120 include “Legs”, “Torso”, “Left Arm”, and “Right Arm.”
Referring to FIG. 4, the user may click on “Legs” in the suggested list of program names 120. As a result, the name of the program is automatically changed into “Legs” in the input field 110. The user may now further edit the name “Legs” if he wishes to do so. Similarly, the user may click on any of the other names in the suggested list of program names 120 to automatically change the data entry in the input field 110 to the new selected program name. As such, the speed and efficiency in which the user performs data entry is greatly increased. The user is no longer required to manually type in a desired entry character by character. Instead, the user may choose from a plurality of predefined data entries (e.g., the program names 120) to perform data entry quickly.
The suggested list of program names 120 are a form of preset responses or predefined data entries according to the present disclosure. These predefined data entries are applicable to a variety of information inputs. In one embodiment, the data entries can be suggested based on the first few characters typed by the user. For example, suppose an attending physician's name is John Doe. As the user is entering the attending physician's name, for example by typing “Jo” or “D”, a list of physician's names would appear. The name that best matches the characters input by the user appears at the beginning of the list.
In some other embodiments, common or popular data entries for each input field are preloaded on the clinician programmer. These common or popular data entries may be presented whether or not the user inputs any data. In some embodiments, these common or popular data entries are defined by a healthcare professional, for example the user of the clinician programmer. The healthcare professional may define a list of popular phrases, words, sentences, names, etc., that he/she knows will be frequently used. These phrases, words, names, sentences or other suitable types of data entry need not be related to just the names of the stimulation program. They may pertain to any other part of the patient file, such as the patient's personal or biographical information, past medical history, or past surgical procedures performed on the patient. In other words, the healthcare professional can generate his/her own database of popular data entries. Since the database is defined by the healthcare professional, it is customized to the healthcare professional. For example, the popular data entries defined by healthcare professional A (and residing in the database generated by that healthcare professional A) may not necessarily be useful or suitable for the popular data entries for healthcare professional B, who may have generated his/her own database of popular data entries based on his/her preferences. The customized database for popular data entries may be stored on the clinician programmer locally, or stored in a remote server. In any case, as a given healthcare professional is using the clinician programmer to perform data entry, the suggested candidates for data entries (e.g., the program names 120) would be selected from the data entries stored in the customized database.
Alternatively, the common or popular data entries may also be generated by analyzing popular data entries that are stored on other clinician programmers, or popular data entries that are stored on a remote electronic server. These data entries reflect what other healthcare professionals consider to be popular or frequently used terms, phrases, sentences, or words, etc. Thus, a user herein may import these popular data entries (or just a subset thereof) into the popular data entry database on his/her own clinician programmer. Of course, the user may customize his/her database of popular data entries by defining some of the popular data entries, and importing other popular data entries from external devices.
In some embodiments, the popular data entries may include a relatively long entry such as a paragraph describing details of a medical procedure, common symptoms of an illness, or side effects of a medicine. In these cases, the paragraphs can be presented with blank spaces reserved for patient specifics (e.g., the patient's name, address, or other patient-specific biographical or medical information). For example, such paragraph may include a phrase “An implant of a percutaneous lead in the lumbar region for lower back pain”, or another suitable frequently-used phrase.
In some embodiments, the predefined data entries may be generated based on the content of existing data in the patient file. For example, the existing data in a patient file may frequently mention knee pain or treatment for ailing knees. The clinician programmer of the present disclosure may analyze the existing data in the patient file, for example by searching for frequently-used keywords such as “pain” or parts of the human body. As a result of this analysis, the clinician programmer of the present disclosure detects that knee pain is a prominent issue for this specific patient for which data entry is performed. Consequently, the clinician programmer may recommend a list of predefined data entries that are related to knee pain in some manner.
According to the various aspects of the present disclosure, the clinician programmer can also present the suggested predefined data entries in a ranked manner. The ranking of each predefined data entry may be assigned by the clinician programmer before these data entries are presented. In some embodiments, the ranking is done as a function of the data entry's relevancy to keywords in the patient's file. For example, in the knee pain example discussed above, since the existing data in the patient file frequently mentions knee pain, then when the healthcare professional starts to input symptoms in the symptoms field, common symptoms and consequences of knee pain will be listed at the beginning of the suggestions. In other words, the data entries that are most relevant to the knee pain are ranked higher than other data entries and presented ahead of other data entries.
In some other embodiments, the ranking may also be done as a function of each date entry's previous usage or frequency of usage. For example, if the program name “Leg” has been the most frequently-used program name for a particular clinician programmer based on past history, then the name “Leg” is assigned the highest ranking among all program names and will be presented first to the user when the program names 120 are shown to the user.
In yet other embodiments, the ranking may be done as a function of a proximity of an external device's proximity to the clinician programmer. For example, when the healthcare professional starts entering data about a patient's medical device or about a patient with a medical device, the clinician programmer locates medical devices with wireless communication capabilities and within communication range to the clinician programmer. The clinician programmer then ranks those devices above other devices not in close proximity. And among these medical devices within communication range, the devices that are closer to the clinician programmer are also ranked higher than the devices that are farther away.
FIG. 5 is a simplified flowchart of a method 300 of input data into a clinician programmer according to the various aspects of the present disclosure. The method 300 includes a step 305, in which the user of a clinician programmer begins entering data into the clinician programmer through a user interface of the clinician programmer. The method 300 includes a step 308, in which a database is searched for preset responses. These preset responses are then displayed. The method 300 then proceeds to a decision step 310 to determine if the user has chosen one of the preset responses. If the answer from the decision step 310 is no, then the method 300 continues to a step 315, in which the user types the data entry character by character. In some alternative embodiments, the data entry need not be done by the user character by character. Instead, the clinician programmer may be communicatively coupled to a network, for example a cloud-computing network, through which the data entry may incorporate an autocomplete feature. The method then proceeds to a decision step 318 to determine if the data entry is finished. If the answer from the decision step 318 is no, then the method 300 loops back to step 308 again. If the answer from the decision step 318 is yes, then the method concludes at step 330, in which the data entry is uploaded to a database or a cloud network.
If the answer from the decision 310 is yes, then the method 300 continues to a step 320, in which the chosen preset responses are entered. The method 300 thereafter proceeds to another decision step 325 to determine if the user wishes to edit the chosen preset response that is entered. If the answer from the decision step 325 is no, then the method 300 finishes at step 330. If the answer from the decision step 325 is yes, then the method proceeds to the step 315 in which the user edits the preset response that was entered character by character (or via an autocomplete feature).
There are several ways the predefined data entries can be stored on the clinician programmer. In some embodiments, the storage capacity of the clinician programmer is partitioned, and one of the partitions is used for storing preset responses. New predefined responses can be added to this partition, and the new responses on multiple clinician programmers can be synced through use of a remote database. The process of uploading the predefined data entries to the remote database is started with the user entering new predefined data entries. Next, the permission actions sequence is carried out. The process of downloading the predefined date entries is similar, with the user requesting predefined date entries and receiving them based on permissions. Multiple users can therefore draw on each other's date entries.
The process of storing, uploading, and downloading the predefined data entries is at least partially reflected in FIGS. 6A-6B, which are flowcharts of simplified example methods 400 and 450 that illustrate communication between a healthcare professional (i.e., the user) using the clinician programmer and a remote database. Referring first to FIG. 6A, the method 400 pertains to the uploading of data from the clinician programmer to the database. The method 400 includes step 405 in which the user enters data. Next, a decision step 410 determines whether the user is authorized to update the database. If the answer is yes, then the database is updated in step 415 by uploading data via a wireless or wired network, such as Wi-Fi or Ethernet. If the user is not authorized to update the database, the method 400 proceeds to step 420, where the attempted update event is recorded locally on the clinician programmer. The method 400 thereafter finishes in step 425.
Referring first to FIG. 6B, the method 450 pertains to the downloading of data from the database to the clinician programmer. The method 400 includes step 455 in which the user requests data. Next, a decision step 460 determines whether the user is authorized to access the database. If the answer is yes, then the database is accessed in step 465 and the requested data is downloaded via a wireless or wired network, such as WiFi or Ethernet. If the user is not authorized to access the database, the method 450 proceeds to step 470, where an error message is displayed on the clinician programmer. The method 450 thereafter finishes in step 475.
FIG. 7 is a simplified flowchart of a method 500 of entering data in a portable electronic device according to the various aspects of the present disclosure. In some embodiments, the portable electronic device is a clinician programmer. It is understood that additional process steps may be performed before, during, or after the steps 505-530. Furthermore, the steps 505-530 need not be performed in the numerical order shown in FIG. 7. It is also understood that one or more steps 505-530 of the method 300 may be performed at least in part via one or more electronic processors.
The method 500 includes a step 505 of generating a list of popular data entries. In some embodiments, the popular data entries are at least in part predefined based on a surgical procedure performed on the patient. In some embodiments, the step 505 includes a step of defining the popular data entries in response to feedback from the healthcare professional. In other embodiments, the method 500 may further include a step of analyzing popular data entries stored on other portable electronic devices. In those embodiments, the step 505 of generating the list of popular data entries includes selecting at least a subset of popular data entries stored on other portable electronic devices.
The method 500 includes a step 510 of saving the list of popular data entries in a memory storage of the portable electronic device.
The method 500 includes a step 515 of receiving, via a touch-sensitive user interface of the portable electronic device, a request from a healthcare professional to perform data entry in an input field.
The method 500 includes a step 520 of displaying, via the touch-sensitive user interface and in response to the receiving the request, a plurality of predefined suggestions as candidates for the data entry. The predefined suggestions are customized for one of: the healthcare professional or the patient. In some embodiments, the step 520 of displaying is performed so that at least a subset of the list of the popular data entries is displayed as the plurality of predefined suggestions.
The method 500 includes a step 525 of detecting, via the touch-sensitive user interface, a selection of one of the plurality of predefined suggestions by the healthcare professional.
The method 500 includes a step 530 of automatically entering the selected predefined suggestion as the data entry in the input field.
In some embodiments, at least some of the predefined suggestions include blank spaces reserved for patient-specific information.
In some embodiments, the data entry is directed to a patient file, and the method 500 may further include the following steps: a step of analyzing an existing data content in the patient file; and a step of recommending the predefined suggestions based on the analyzed content.
In some embodiments, the method 500 may further comprise a step of assigning a respective rank to each of the plurality of predefined suggestions according to one or more predetermined criteria. In these embodiments, the step 520 of displaying the predefined suggestions includes display the plurality of predefined suggestions according to their respective ranks. In some embodiments, the predetermined criteria include frequency of past use of each of the predefined suggestions. In some embodiments, the predetermined criteria include proximity of plurality of medical devices to the portable electronic device, wherein the data entry is directed toward the medical devices.
FIG. 8 shows a block diagram of one embodiment of the electronic programmer (CP) discussed herein. For example, the electronic programmer may be a clinician programmer (CP) configured to perform the data entry discussed above. It is understood, however, that alternative embodiments of the electronic programmer may be used to perform these representations as well.
The CP includes a printed circuit board (“PCB”) that is populated with a plurality of electrical and electronic components that provide power, operational control, and protection to the CP. With reference to FIG. 8, the CP includes a processor 600. The processor 600 controls the CP. In one construction, the processor 600 is an applications processor model i.MX515 available from Free scale Semiconductor ®. More specifically, the i.MX515 applications processor has internal instruction and data caches, multimedia capabilities, external memory interfacing, and interfacing flexibility. Further information regarding the i.MX515 applications processor can be found in, for example, the “IMX51CEC, Rev. 4” data sheet dated August 2010 and published by Free scale Semiconductor ® at www.freescale.com. The content of the data sheet is incorporated herein by reference. Of course, other processing units, such as other microprocessors, microcontrollers, digital signal processors, etc., can be used in place of the processor 600.
The CP includes memory, which can be internal to the processor 600 (e.g., memory 605), external to the processor 600 (e.g., memory 610), or a combination of both. Exemplary memory include a read-only memory (“ROM”), a random access memory (“RAM”), an electrically erasable programmable read-only memory (“EEPROM”), a flash memory, a hard disk, or another suitable magnetic, optical, physical, or electronic memory device. The processor 600 executes software that is capable of being stored in the RAM (e.g., during execution), the ROM (e.g., on a generally permanent basis), or another non-transitory computer readable medium such as another memory or a disc. The CP also includes input/output (“I/O”) systems that include routines for transferring information between components within the processor 600 and other components of the CP or external to the CP.
Software included in the implementation of the CP is stored in the memory 605 of the processor 600, RAM 610, ROM 615, or external to the CP. The software includes, for example, firmware, one or more applications, program data, one or more program modules, and other executable instructions. The processor 600 is configured to retrieve from memory and execute, among other things, instructions related to the control processes and methods described below for the CP.
One memory shown in FIG. 8 is memory 610, which may be a double data rate (DDR2) synchronous dynamic random access memory (SDRAM) for storing data relating to and captured during the operation of the CP. In addition, a secure digital (SD) multimedia card (MMC) may be coupled to the CP for transferring data from the CP to the memory card via slot 615. Of course, other types of data storage devices may be used in place of the data storage devices shown in FIG. 8.
The CP includes multiple bi-directional radio communication capabilities. Specific wireless portions included with the CP are a Medical Implant Communication Service (MICS) bi-directional radio communication portion 620, a Wi-Fi bi-directional radio communication portion 625, and a Bluetooth bi-directional radio communication portion 630. The MICS portion 620 includes a MICS communication interface, an antenna switch, and a related antenna, all of which allows wireless communication using the MICS specification. The Wi-Fi portion 625 and Bluetooth portion 630 include a Wi-Fi communication interface, a Bluetooth communication interface, an antenna switch, and a related antenna all of which allows wireless communication following the Wi-Fi Alliance standard and Bluetooth Special Interest Group standard. Of course, other wireless local area network (WLAN) standards and wireless personal area networks (WPAN) standards can be used with the CP.
The CP includes three hard buttons: a “home” button 635 for returning the CP to a home screen for the device, a “quick off” button 640 for quickly deactivating stimulation IPG, and a “reset” button 645 for rebooting the CP. The CP also includes an “ON/OFF” switch 650, which is part of the power generation and management block (discussed below).
The CP includes multiple communication portions for wired communication. Exemplary circuitry and ports for receiving a wired connector include a portion and related port for supporting universal serial bus (USB) connectivity 655, including a Type A port and a Micro-B port; a portion and related port for supporting Joint Test Action Group (JTAG) connectivity 660, and a portion and related port for supporting universal asynchronous receiver/transmitter (UART) connectivity 665. Of course, other wired communication standards and connectivity can be used with or in place of the types shown in FIG. 8.
Another device connectable to the CP, and therefore supported by the CP, is an external display. The connection to the external display can be made via a micro High-Definition Multimedia Interface (HDMI) 670, which provides a compact audio/video interface for transmitting uncompressed digital data to the external display. The use of the HDMI connection 670 allows the CP to transmit video (and audio) communication to an external display. This may be beneficial in situations where others (e.g., the surgeon) may want to view the information being viewed by the healthcare professional. The surgeon typically has no visual access to the CP in the operating room unless an external screen is provided. The HDMI connection 670 allows the surgeon to view information from the CP, thereby allowing greater communication between the clinician and the surgeon. For a specific example, the HDMI connection 670 can broadcast a high definition television signal that allows the surgeon to view the same information that is shown on the LCD (discussed below) of the CP.
The CP includes a touch screen I/O device 675 for providing a user interface with the clinician. The touch screen display 675 can be a liquid crystal display (LCD) having a resistive, capacitive, or similar touch-screen technology. It is envisioned that multitouch capabilities can be used with the touch screen display 675 depending on the type of technology used.
The CP includes a camera 680 allowing the device to take pictures or video. The resulting image files can be used to document a procedure or an aspect of the procedure. Other devices can be coupled to the CP to provide further information, such as scanners or RFID detection. Similarly, the CP includes an audio portion 685 having an audio codec circuit, audio power amplifier, and related speaker for providing audio communication to the user, such as the clinician or the surgeon.
The CP further includes a power generation and management block 690. The power block 690 has a power source (e.g., a lithium-ion battery) and a power supply for providing multiple power voltages to the processor, LCD touch screen, and peripherals.
In one embodiment, the CP is a handheld computing tablet with touch screen capabilities. The tablet is a portable personal computer with a touch screen, which is typically the primary input device. However, an external keyboard or mouse can be attached to the CP. The tablet allows for mobile functionality not associated with even typical laptop personal computers. The hardware may include a Graphical Processing Unit (GPU) in order to speed up the user experience. An Ethernet port (not shown in FIG. 8) may also be included for data transfer.
It is understood that a patient programmer may be implemented in a similar manner as the clinician programmer shown in FIG. 8.
FIG. 9 shows a block diagram of one embodiment of an implantable medical device. In the embodiment shown in FIG. 9, the implantable medical device includes an implantable pulse generator (IPG). The IPG includes a printed circuit board (“PCB”) that is populated with a plurality of electrical and electronic components that provide power, operational control, and protection to the IPG. With reference to FIG. 9, the IPG includes a communication portion 700 having a transceiver 705, a matching network 710, and antenna 712. The communication portion 700 receives power from a power ASIC (discussed below), and communicates information to/from the microcontroller 715 and a device (e.g., the CP) external to the IPG. For example, the IPG can provide bi-direction radio communication capabilities, including Medical Implant Communication Service (MICS) bi-direction radio communication following the MICS specification.
The IPG provides stimuli to electrodes of an implanted medical electrical lead (not illustrated herein). As shown in FIG. 9, N electrodes are connected to the IPG. In addition, the enclosure or housing 720 of the IPG can act as an electrode. The stimuli are provided by a stimulation portion 225 in response to commands from the microcontroller 215. The stimulation portion 725 includes a stimulation application specific integrated circuit (ASIC) 730 and circuitry including blocking capacitors and an over-voltage protection circuit. As is well known, an ASIC is an integrated circuit customized for a particular use, rather than for general purpose use. ASICs often include processors, memory blocks including ROM, RAM, EEPROM, FLASH, etc. The stimulation ASIC 730 can include a processor, memory, and firmware for storing preset pulses and protocols that can be selected via the microcontroller 715. The providing of the pulses to the electrodes is controlled through the use of a waveform generator and amplitude multiplier of the stimulation ASIC 730, and the blocking capacitors and overvoltage protection circuitry 735 of the stimulation portion 725, as is known in the art. The stimulation portion 725 of the IPG receives power from the power ASIC (discussed below). The stimulation ASIC 730 also provides signals to the microcontroller 715. More specifically, the stimulation ASIC 730 can provide impedance values for the channels associated with the electrodes, and also communicate calibration information with the microcontroller 715 during calibration of the IPG.
The IPG also includes a power supply portion 740. The power supply portion includes a rechargeable battery 745, fuse 750, power ASIC 755, recharge coil 760, rectifier 763 and data modulation circuit 765. The rechargeable battery 745 provides a power source for the power supply portion 740. The recharge coil 760 receives a wireless signal from the PPC. The wireless signal includes an energy that is converted and conditioned to a power signal by the rectifier 763. The power signal is provided to the rechargeable battery 745 via the power ASIC 755. The power ASIC 755 manages the power for the IPG. The power ASIC 755 provides one or more voltages to the other electrical and electronic circuits of the IPG. The data modulation circuit 765 controls the charging process.
The IPG also includes a magnetic sensor 780. The magnetic sensor 780 provides a “hard” switch upon sensing a magnet for a defined period. The signal from the magnetic sensor 780 can provide an override for the IPG if a fault is occurring with the IPG and is not responding to other controllers.
The IPG is shown in FIG. 9 as having a microcontroller 715. Generally speaking, the microcontroller 715 is a controller for controlling the IPG. The microcontroller 715 includes a suitable programmable portion 785 (e.g., a microprocessor or a digital signal processor), a memory 790, and a bus or other communication lines. An exemplary microcontroller capable of being used with the IPG is a model MSP430 ultra-low power, mixed signal processor by Texas Instruments. More specifically, the MSP430 mixed signal processor has internal RAM and flash memories, an internal clock, and peripheral interface capabilities. Further information regarding the MSP 430 mixed signal processor can be found in, for example, the “MSP430G2x32, MSP430G2x02 MIXED SIGNAL MICROCONTROLLER” data sheet; dated December 2010, published by Texas Instruments at www.ti.com; the content of the data sheet being incorporated herein by reference.
The IPG includes memory, which can be internal to the control device (such as memory 790), external to the control device (such as serial memory 795), or a combination of both. Exemplary memory include a read-only memory (“ROM”), a random access memory (“RAM”), an electrically erasable programmable read-only memory (“EEPROM”), a flash memory, a hard disk, or another suitable magnetic, optical, physical, or electronic memory device. The programmable portion 785 executes software that is capable of being stored in the RAM (e.g., during execution), the ROM (e.g., on a generally permanent basis), or another non-transitory computer readable medium such as another memory or a disc.
Software included in the implementation of the IPG is stored in the memory 790. The software includes, for example, firmware, one or more applications, program data, one or more program modules, and other executable instructions. The programmable portion 785 is configured to retrieve from memory and execute, among other things, instructions related to the control processes and methods described below for the IPG. For example, the programmable portion 285 is configured to execute instructions retrieved from the memory 790 for sweeping the electrodes in response to a signal from the CP.
