FIELD OF THE DISCLOSURE

The present disclosure relates to medical systems, and in particular, but not exclusively, to catheter devices.

BACKGROUND

A wide range of medical procedures involve placing probes, such as catheters, within a patient's body. One medical procedure in which these types of probes or catheters have proved extremely useful is in the treatment of cardiac arrhythmias. Cardiac arrhythmias and atrial fibrillation in particular, persist as common and dangerous medical ailments, especially in the aging population.

Diagnosis and treatment of cardiac arrhythmias include mapping the electrical properties of heart tissue, especially the endocardium and the heart volume, and selectively ablating cardiac tissue by application of energy. Catheters are inserted into the heart chamber and optionally around the heart chamber during such procedures. In most procedures, multiple catheters are inserted into the patient. Catheters may include mapping, ablation, temperature sensing and image sensing catheters. Some catheters are dedicated for placement in specific parts of the anatomy, e.g., coronary sinus, esophagus, atrium, ventricle. The catheters have multiple electrical channels, some more than others depending on the number of sensors and electrodes included in each catheter. The number and type of catheters depends on the procedure and on the physician preferred workflow.

DESCRIPTION OF EXAMPLE EMBODIMENTS

Overview

A mapping and ablation system may include a console, which allows connecting multiple catheters to the console using cables via respective ports provided in the console. Catheters may be plugged into any one of a plurality of the ports based on selecting the right cable for the selected port. The ports may differ in the number of pins that they have, e.g., a 25-pin port, a 100-pin port, corresponding to the number of electrical channels (e.g., electrogram channels and optionally ablation and/or position signal channels). By way of example, a catheter that only requires a 25-pin port might be connected to a 100-pin port and then another catheter that needs a 100-pin port cannot be connected, or cannot be easily connected, at the same time as the other catheter. The operator may be confused as to which catheter should be connected to which port and may not make the best selection. The operator may also be confused as to which cable to use for connecting to the available ports. By way of another example, a console may include 8 ports with 96 electrogram channels divided among the 8 ports. If a port with 34 electrogram channels is used for a catheter with ten electrodes or for a catheter performing ablation only, then the electrogram channels are wasted and another catheter needing 30 electrogram channels cannot then also be connected to the console and have access to the 30 electrogram channels needed for that catheter. An additional problem is that cables may be sterile and separately packaged in blister packaging. If the connection protocol is unclear, the operator may open the wrong cable package and once the blister packaging is opened, the cable is no longer sterile, thereby leading to wastage.

Examples of the present disclosure solve at least some of the above problems by providing an automated catheter connection configuration system and method. In some examples, the physician or operator may select the catheters that will be used in a medical procedure from a list of available catheters, for example, using pull down lists. Software then finds a connection configuration with which to couple the selected catheters with the ports. The connection configuration is then rendered to a display to show the physician how to couple the catheters to the ports. The connection configuration may also indicate the cables that should be used to connect the respective catheters to the ports.

In another example, the physician or operator may select a particular medical procedure that is to be performed and the software may provide a relevant list of catheters and/or probes that may be used in the procedure. In some examples, the physician may select a workflow template thereby selecting the catheters to be used in a medical procedure. For example, one or more physicians may save different workflow templates including the catheters used in the workflow and optionally associated procedure types performed by each catheter. The selected workflow template may be retrieved from memory thereby selecting the catheters (and procedure types) to be used. The catheters and optionally the procedure types to be performed in the selected workflow template are displayed. The displayed catheters and procedure types may be changed by the physician.

In some examples, the electrical channel profiles of the catheters (e.g., how many electrogram, ablation, and position channels the respective catheters have) are compared to the electrical channel profiles of the available ports. The connection configuration may be optimized by first comparing the catheter having the largest number of electrical channels to the ports, followed by the next largest, and so on. In some examples, the procedure types (e.g., mapping, imaging, and/or ablation) used by the respective catheters may also selected by the physician and used by the software to determine the connection configuration. By way of example, if a catheter has both mapping electrodes and ablation electrodes, but the catheter is only going to be used for ablation, then the catheter does not need port connections for the mapping electrodes, and vice-versa. In another example, a mapping and/or ablation catheter may have position sensing and/or temperature sensing capability. If the sensing feature is not being used for a particular workflow, then the catheter may not need port connections for the sensors, e.g., position and/or temperature sensors. By way of another example, if after performing the matching process, the software cannot find a connection configuration in which all the selected catheters can be connected to the ports at the same time, the software may then try to find a connection configuration in which the catheters used for mapping are connected for a first time period to the ports, and then the catheters used for ablation are connected for a second time period to the ports, based on the assumption that mapping is normally followed by ablation.

In some examples, the ports are statically labeled (i.e., the labels do not change over time), for example, using colors, shapes, names and/or numbers. The cable and/or cable packaging may also be labeled, for example, using colors, shapes, names and/or numbers. The connection configuration rendered to the display may list the port label and cable/cable packaging label for each of the selected catheters. For example, catheter A (e.g., a basket catheter) should be connected to port1using the red cable, catheter B (e.g., a balloon catheter) should be connected to port5using the green cable and catheter C (e.g., a focal catheter) should be connected to port4using the blue cable.

In some examples, the ports are dynamically labeled using (“mini”) port displays adjacent to each port. The port displays may indicate the cable that should be connected to each port, while a main display indicates the cable that should be connected to each catheter. For example, the main display may indicate that catheter A should be connected using the red cable, catheter B using the green cable, and catheter C using the blue cable. Then the port displays of ports1,5, and4display “red”, “green”, and “blue”, respectively, indicating the cables that should be connected to the ports.

In some examples, the port displays may indicate the catheter and cable that should be connected to each port. For example, the port display of port1may indicate that catheter A should be connected using the red cable, the port display of port5may indicate that catheter B should be connected using the green cable, and the port display of port4may indicate that catheter C should be connected using the blue cable.

System Description

Reference is now made toFIG.1, which is a schematic, pictorial illustration of a medical system20, in accordance with an example of the present disclosure. The system20includes a catheter40′ configured to be inserted into a body part (e.g., a chamber of a heart26) of a living subject (e.g., a patient28). A physician30navigates the catheter40′ (for example, a basket catheter produced by Biosense Webster, Inc. of Irvine, Calif., USA), seen in detail in inset45, to a target location in the heart26of the patient28, by manipulating a deflectable segment of an insertion tube22of the catheter40′. In the pictured example, physician30uses catheter40′ to perform electro-anatomical mapping of a cardiac chamber.

The catheter40′ includes a distal end33. The distal end33of the catheter40′ includes an assembly35(e.g., a basket assembly as shown inFIG.1or a balloon assembly or any suitable distal end assembly, e.g., grid, flexible splines or a focal catheter) on which at least one (e.g., multiple) catheter electrode(s)48(only some labeled for the sake of simplicity) are disposed. The electrodes48are configured to contact tissue at respective locations with the chamber of the heart.

FIG.1also shows another catheter40″ inserted into a chamber of the heart26. The catheter40″ may be any suitable catheter, for example, a pacing catheter or an imaging catheter such as an ultrasound catheter or a focal catheter. The catheter40″ is connected via a cable38to a port46on a console24. The console24includes other ports46for connecting other catheters to the console24.

The distal end33of the catheter40′ may comprise magnetic coil sensors50A and50B. The magnetic coil sensor50A is shown in inset45at the distal edge of insertion tube22(i.e., at the proximal edge of basket assembly35). Magnetic coil sensors50A and50B and electrodes48are connected by wires running through insertion tube22to various driver circuitries in console24.

In some examples, system20comprises a magnetic-sensing sub-system. Patient28is placed in a magnetic field generated by a pad containing multiple magnetic field generator coils42, which are driven by a magnetic sensing driver unit43. The magnetic field generator coils42are configured to generate respective alternating magnetic fields, having respective different frequencies, into a region where a body-part (e.g., the heart26) of a living subject (e.g., the patient28) is located. The magnetic coil sensors50A and50B are configured to output electrical signals responsively to detecting the respective magnetic fields. The generated signals are transmitted to console24and become corresponding electrical inputs to processing circuitry41.

In some examples, the processing circuitry41uses position-signals received from the electrodes48or body surface electrodes49, and the magnetic sensor50to estimate a position of the assembly35inside a body part, such as inside a cardiac chamber. In some examples, the processing circuitry41correlates the position signals received from the electrodes48,49with previously acquired magnetic location-calibrated position signals, to estimate the position of the assembly35inside the body part. The position coordinates of the electrodes48may be determined by the processing circuitry41based on, among other inputs, measured impedances, voltages or on proportions of currents distribution, between the electrodes48and the body surface electrodes49.

The method of position sensing using current distribution measurements and/or external magnetic fields is implemented in various medical applications, for example, in the Carto® system, produced by Biosense Webster Inc. (Irvine, Calif.), and is described in detail in U.S. Pat. Nos. 5,391,199, 6,690,963, 6,484,118, 6,239,724, 6,618,612, 6,332,089, 7,756,576, 7,869,865, and 7,848,787, in PCT Patent Publication WO 96/05768, and in U.S. Patent Application Publications 2002/0065455 A1, 2003/0120150 A1 and 2004/0068178 A1.

Processing circuitry41, typically part of a general-purpose computer, is further connected via a suitable front end and interface circuits44, to receive signals from body surface-electrodes49. Processing circuitry41is connected to surface-electrodes49by wires running through a cable39to the chest of patient28. The catheter40′ includes a connector47disposed at the proximal end29of the insertion tube22for coupling with the processing circuitry41via one of the ports46of the console24. In some examples, processing circuitry41renders to a display27, a representation31of at least a part of the catheter40′ and a body-part.

Processing circuitry41is typically programmed in software and/or firmware to carry out the functions described herein. The software may be downloaded to the computer in electronic form, over a network, for example, or it may, alternatively or additionally, be provided and/or stored on non-transitory tangible media, such as magnetic, optical, or electronic memory. The system20may also include a memory51used by the processing circuitry41.

The example illustration shown inFIG.1is chosen purely for the sake of conceptual clarity.FIG.1shows only elements related to the disclosed techniques for the sake of simplicity and clarity. System20typically comprises additional modules and elements that are not directly related to the disclosed techniques, and thus are intentionally omitted fromFIG.1and from the corresponding description. The elements of system20and the methods described herein may be further applied, for example, to control an ablation of tissue of heart26.

Reference is now made toFIG.2, which is a schematic view of different cables38, catheters40configured to be inserted into a body part of a living subject, and console ports46in the system20ofFIG.1.

The catheters40may include a respective electrical connector at their proximal ends with which to couple the catheters40via respective ones of the cables38with the ports46. The catheters40may have respective electrical channel profiles. Some of the electrical channel profiles of the catheters40may be the same, and in some cases the electrical channel profiles of the catheters40may all be different. An electrical channel profile of a catheter defines the total number of electrical connections to/from the catheter via the catheter electrical connector and the arrangement of those electrical connections in the catheter electrical connector (e.g., an arrangement of the pins of the catheter electrical connector). The electrical channel profile of the catheter may also include the number of sub-categories of electrical channels and their arrangement among the pins. For example, the electrical channel profile of a catheter may include X electrogram electrical connections (e.g., to X corresponding mapping electrodes of the catheter), Y ablation electrical connections (e.g., to Y ablation electrodes of the catheter), and Z position signal electrical connections to carry signals to/from position signals in the catheter, and so on. The electrical channels may also include electrical connections to carry signals to imaging modalities such as ultrasound. Each of X, Y and Z represents an integer number, e.g., a number between 1-500.

The console24includes the ports46configured to be coupled with the catheters40via respective ones of the cables38. The ports46may have respective electrical channel profiles. Some of the electrical channel profiles of the ports46may be the same, and in some cases the electrical channel profiles of the ports46may all be different. An electrical channel profile of a port defines the total number of electrical connections through the port and the arrangement of those electrical connections in the port (e.g., an arrangement of the pins of the port). The electrical channel profile of the port may also include the number of sub-categories of electrical channels and their arrangement among the pins. For example, the electrical channel profile of the port may include X electrogram electrical connections (e.g., connected to electrogram processing circuitry in the console24), Y ablation electrical connections (e.g., connected to ablation power generator(s) in the console24), and Z position signal electrical connections (e.g., connected to position tracking circuitry in the console24), and so on. The electrical channels may also include electrical connections to carry signals to imaging processing circuitry in the console24.

In some examples, the ports46are provided with indications which are static (i.e., the indications do not change), for example, using colors, shapes, names and/or numbers. The ports46shown inFIG.2are labeled1-5.

Each of the cables38includes two respective electrical connectors47and47′, one connector47to couple with one or more of the ports46and another connector47′ to couple with one or more of the catheters40. The cables38may have respective electrical channel profiles. An electrical channel profile of a cable defines the total number of electrical connections through the cable and the arrangement of those electrical connections in the electrical connectors of the cable (e.g., an arrangement of the pins of the electrical connectors). The electrical channel profile of the cable may also include the number of sub-categories of electrical channels and their arrangement among the pins of the respective electrical connectors. For example, the electrical channel profile of the cable may include X electrogram electrical connections (e.g., for connection to electrogram channels of the catheters40and ports46), Y ablation electrical connections (e.g., for connection to ablation channels of the catheters40and ports46), and Z position signal electrical connections (e.g., for connection to position signal channels of the catheters40and ports46), and so on.

The cables38and/or cable packaging66may be provided with indications (e.g., labels), for example, using colors, shapes, names and/or numbers. For example, one cable38and/or its connectors may be green, or include a green band, and/or include a green label on the cable packaging66.

Reference is now made toFIGS.3and4.FIG.3is a flowchart100including steps in a method of operation of the system20ofFIG.1.FIG.4is a schematic view of a user interface screen70to select catheters40for use in the system20ofFIG.1. The processing circuitry41is configured to receive user input selecting respective ones of the catheters40to be used in a medical procedure (block102).

In some examples, the processing circuitry is configured to receive user input selecting at least one procedure type (e.g., mapping or ablation) to be performed during the medical procedure. The catheters40and optionally the procedure types may be selected using the user interface screen70rendered to the display27as shown inFIG.4.

In some examples, the processing circuitry41is configured to receive user input selecting a workflow template (input field71) thereby selecting the catheters40to be used in a medical procedure. For example, one or more physicians may save different workflow templates including the catheters40used in the workflow and optionally associated procedure types performed by each catheter40. The selected workflow template may be retrieved from the memory51thereby selecting the catheters40(and procedure types) to be used. The catheters40and optionally the procedure types to be performed in the selected workflow template are displayed on the display27. The displayed catheters40and procedure types may be changed by the physician30.

Once the catheters40and the procedure types have been selected, the physician30may select the “find connection configuration” button72for the processing circuitry41to proceed to find the connection configuration of the selected catheters40with the ports46.

In some examples, the processing circuitry41is configured to set at least one of the respective electrical channel profiles of the selected catheter(s)40responsively to the corresponding procedure type(s) (block104). For example, if one of the selected catheters40has mapping electrodes and ablation electrodes, and the procedure type selected for that catheter is mapping, the ablation channels of that catheter do not need to be coupled with the ablation circuitry in the console24and therefore, the ablation channels of that catheter may be ignored when finding the connection configuration.

In some examples, the processing circuitry41is configured to match the respective electrical channel profiles of the respective selected catheters40to the respective electrical channel profiles of respective ones of the ports46and the respective electrical channel profiles of respective ones of the cables38(block106). In some examples, the processing circuitry41is configured to match respective electrogram channel sets (and/or ablation channel sets and/or position signal channel sets) of the respective selected catheters40to respective electrogram channel sets (and/or ablation channel sets and/or position signal channel sets) of the respective ports46and the respective electrogram channel sets (and/or ablation channel sets and/or position signal channel sets) of respective ones of the cables38. The number of channels as well as the arrangement of those channels (e.g., pin arrangements) in the connectors of the catheters40, the ports46and the cables38(and the connectors of the cables38) may be matched by the processing circuitry41. The electrical channel profiles of the selected catheters40may be individually compared with the electrical channel profiles of the ports46and the cables38until an optimal connection configuration is found. In some examples, the connection configuration may be found in a more systematic fashion, for example using the matching process described with reference toFIG.5. In some examples, connection configurations of different combination of catheters40with the ports46via different cables38may be pre-computed and saved so that when a given catheter combination is selected, the pre-computed optimal connection configuration may be retrieved from the memory51.

Reference is now made toFIG.5, which is a flowchart150including steps in a catheter matching sub-method of the method ofFIG.3. The processing circuitry41is configured to select from the selected catheters40(in the selection received in the step of block102(FIG.3)), the catheter40with the largest electrical channel profile (e.g., the largest number of electrical connections or the largest number of electrogram channels etc.) (block152). The processing circuitry41is configured to compare the electrical channel profile with the electrical channel profiles of the unassigned ports46optionally starting with the port46having the smallest electrical channel profile (block154). Once a match is found in the step of block154, the processing circuitry41is configured to assign the selected catheters40to the matching port46in the connection configuration (block156). At a decision block158, the processing circuitry41is configured to determine if there are more catheters40in the selection received in the step of block102(FIG.3) to be matched using the above steps. If there are no more catheters40in the received selection to be matched using the above steps, the process ends (block160). If there is one or more catheters40in the received selected to be matched using the above steps, the processing circuitry41is configured to select the next catheter40having the next largest electrical channel profile (block162) and the steps of blocks154-158are repeated with the newly selected catheter. The above steps may also be used to find the correct cables38for the found catheter-port pairs.

Reference is again made toFIG.4. If after performing the matching step of block106, the processing circuitry41cannot find a connection configuration in which all the selected catheters40can be connected to the ports46at the same time, the processing circuitry41may then try to find a connection configuration in which the catheters40are connected during different time periods. For example, catheters40used for mapping may be connected for a first time period to the ports46, and then the catheters40used for ablation may be connected for a second time period to the ports46, based on the assumption that mapping is normally followed by ablation. Therefore, the processing circuitry41may be configured to prioritize an order of which ones of the selected catheters40to couple with the ports46of the console24responsively to the respective procedure type(s) that the selected catheters40will be used for (e.g., mapping or ablation) (block108).

The processing circuitry41is configured to find the connection configuration with which to couple the respective selected catheters40with ones of the ports46, responsively to (matching) the respective electrical channel profiles of the respective selected catheters40and the respective electrical channel profiles of the ports46(block110). In some examples, the processing circuitry41is configured to find the connection configuration responsively to matching, for example, using the matching step of block106or the matching method described with reference toFIG.5. In some examples, the processing circuitry41is configured to find the connection configuration with which to couple the respective selected catheters40with the ones of the ports46for the same time period during the medical procedure, responsively to (matching) the respective electrical channel profiles of the respective selected catheters40and the respective electrical channel profiles of the ports46. In some examples, the processing circuitry41is configured to find the connection configuration with which to couple the respective selected catheters40with ones of the ports46via respective cables38, responsively to the respective electrical channel profiles of the respective selected catheters40, the respective electrical channel profiles of the ports46, and respective electrical channel profiles of the respective cables38.

The processing circuitry41is configured to find the connection configuration with which to couple the respective selected catheters40with ones of the ports46(and the cables38), responsively to the respective electrical channel profiles of the respective selected catheters40, the respective electrical channel profiles of the ports46(and the cables38), and the procedure type(s) to be performed by the respective selective catheters40as described above with reference to the steps of blocks104and108, which described how the procedure type(s) may affect finding the connection configuration.

Reference is now made toFIG.6, which is a schematic view of a port panel74(in the console24ofFIG.1) and a user interface window76on display27showing a connection configuration78in the system20ofFIG.1. Reference is also made toFIG.4. In some examples, the processing circuitry41is configured to render to the display27the connection configuration78comprising a mapping between the respective selected catheters40and respective indications of the ports46and the cables38(block112).

In the example ofFIG.6, the ports46are provided with static (i.e., fixed) indications (e.g., labels), for example, using colors, shapes, names and/or numbers. The cables38and/or cable packaging66may also be labeled, for example, using colors, shapes, names and/or numbers. In the example ofFIG.6, the ports are labeled1-5, the cables38are labeled using colors, and the connection configuration78rendered to the display27lists the port number and cable/cable packaging color for each of the selected catheters40. For example, mapping catheter A (e.g., a basket catheter) should be connected to port1using the red cable, the ablation catheter B (e.g., a balloon catheter) should be connected to port5using the green cable, and catheter C (e.g., a focal catheter) should be connected to port4using the blue cable.

Reference is now made toFIG.7, which is a schematic view of an alternative port panel80and an alternative user interface screen82showing a connection configuration84in the system20ofFIG.1. In some examples, the system20may include respective port-displays86for the ports46with one port-display86per port46. The processing circuitry41is configured to render to at least some of the port displays86respective indications of the respective cables38(e.g., by color, name, number or picture) that should be connected to respective ports46responsively to the connection configuration84. The processing circuitry41is also configured to render to the display27indications of the respective cable38that should be connected to each catheter40. For example, as shown inFIG.7, the user interface screen82rendered on the display27indicates that mapping catheter A should be connected using the red cable, ablation catheter B should be connected using the green cable, and catheter C should be connected using the blue cable. The port displays86-1,86-5,86-4, of ports1,5, and4display “red”, “green”, and “blue” using text, respectively, indicating how the cables38that should be connected to the ports46. Alternatively, or additionally, the port-displays86may indicate the colors of the cables to be connected using a colored shape or colored text. In some examples, the port-displays86may be configured as ring-shaped liquid crystal displays (LCD) displays (controlled by software) that change color according to the cables to be attached to the respective ports46.

Reference is now made toFIG.8, which is a schematic view of yet another alternative port panel90for use in the system20ofFIG.1. In some examples, the processing circuitry41is configured to render to at least some of the port displays86indications of the respective selected catheters40and cables38that should be connected to respective ones of the ports46responsively to the connection configuration. For example, as shown inFIG.8, the port display86-1of port1indicates that mapping catheter A should be connected using the red cable, the port display86-5of port5indicates that ablation catheter B should be connected using the green cable, and the port display86of port4indicates that catheter C should be connected using the blue cable.
