Title: Temperature controlled rf coagulation
Inventor: LENNOX CHARLES D
IPC: A61B18/12
Filed: 1991-04-26
Abstract: Radiofrequency medical devices for ohmic heating of tissue of a patient include a temperature sensor (29) earned by and in thermally conductive relationship with a thermally conductive electrode (28). The sensor (29) is connected for feedback to a control circuit (6) that modulates RF power applied to the electrode according to the signal received from the temperature sensor (29). The control circuit (6) and RF power supply alternate between two operating modes. In the first mode the RF power supply applies RF power to the electrode (28). In the second mode the control circuit (6) senses a signal from the temperature sensor (29) in the absence of RF signal. The control circuit (6) compares the signal from the temperature sensor (29) to a set value and modu-lates the RF power applied to the electrode (28) in accordance with the set value.

IPC: A63H27/04
Filed: 1991-06-11
Abstract: A flying amusement device (10) including first and second rotary elements (12, 14) separated by a hub (16). Each of the rotary elements includes a set of lift members (18, 20) which provide lift in a common direction when the device is rotated about the hub. A length of flexible line (26) is connected to the hub (16) and wound thereabout prior to use. The device is held in the user's hand with the free end of the flexible line connected to the user's throwing hand. The device is then thrown outwardly from the body of the user with a snapping motion of the wrist to impart rotation to the device. This rotation produces lift, and further rotation is imparted to the device due to the device unwinding from the flexible sine as it travels away from the user. Upon fully unwinding the flexible line (26) from the hub (16), the continued rotation of the device (10) causes the flexible line (26) to be rewound upon the hub (16), thus drawing the device back towards the user.  During the travel of the device (10) away from and towards the user, the continued rotation of the device produces a lift which causes the device to fly through the air.

Title: Subcutaneous multi-electrode sensing system
Inventor: BENNETT TOM D
IPC: A61N1/362
Filed: 1992-02-04
Abstract: A method and apparatus for providing an enhanced capability of detecting and gathering electrical cardiac signals via an array of relatively closely spaced subcutaneous electrodes (located on the body of an implanted device) which may be employed with suitable switching circuits, signal processors, and memory to process the electrical cardiac signals between any selected pair or pairs of the electrode array in order to provide a leadless, orientation insensitive means for receiving the electrical signal from the heart. This far-field EGM may be used to provide storage and analysis of arrhythmic events and to provide control signals for the delivery of various therapies including pacing, cardioversion and defibrillation therapies as well as the delivery of antiarrhythmic drugs, and, in the pacing context, to effect capture detection and automatic stimulation threshold adaptation, recording of PMT  episodes, measurement of refractory periods in order to set timing windows for antitachy pacing therapies, and as a control signal for use in adjusting pacing rate to physiologic demand. The housing or case of the subcutaneously implanted medical device is modified to provide an array of electrodes which may be selectively or sequentially coupled in one or more pairs to the terminals of one or more sense amplifiers to pick up, amplify and process the electrical cardiac signals across each electrode pair. In one embodiment, the signals from the selected electrode pairs may be stored and compared to one another in order to determine the sensing vector which provides the largest cardiac signal (in a test mode). Following completion of the test mode, the system may employ the selected subcutaneous ECG signal vector for a number of applications. The implanted device possesses analog-to-digital conversion circuitry for sampling and converting the selected subcutaneous ECG signal to digital data which is stored in a recirculating buffer, the contents of which are transferred to RAM for later data retrieval either periodically or upon the occurrence of an event of interest. In another embodiment, the selected subcutaneous ECG signal is used to confirm capture in conjunction with an algorithm for determining the stimulation threshold of the heart and set stimulation pulse energy at a level exceeding the threshold by a desired safety margin. Further embodiments include replacing the switching approach with parallel linear and nonlinear combinational processing of the signals from the orthogonal electrode pairs of the electrode array, to develop and employ continuous signals insensitive to the orientation variations of the electrode array. These linear and nonlinear embodiments would be used for improving the data storage and autocapture embodiments by providing an optimal signal at all times, while avoiding the switching process.
