摘要:
An implantable medical device (IMO) includes one or more stimulation engines (SEs) and selectively connectable output switching circuitry for driving a plurality of output nodes associated with a respective plurality of electrodes of the IMO's lead system when implanted in a patient. The output switching circuitry may be configured to facilitate self-test mode (STM) functionality in the IMO (e.g., when it is in a hermetically sealed package) by using a dual mode switch in series with a stimulation engine selection switch with respect to each output node in the output switching circuitry under mode selection control.

A battle simulation system includes a limb immobilization device. The limb immobilization device is operative for immobilizing a limb of a user in response to receipt of the control signal indicating a hit to the limb of the user. The limb immobilization device may at least partially immobilize the limb. The immobilization may be voluntary or involuntary.

A valvuloplasty system comprises a balloon adapted to be placed adjacent leaflets of a valve. The balloon is inflatable with a liquid. The system further includes a shock wave generator within the balloon that produces shock waves. The shock waves propagate through the liquid and impinge upon the valve to decalcify and open the valve.

摘要:
A method for determining a cardiac shock strength, for example the programmed first-therapeutic shock strength of an implantable cardioverter defibrillator (ICD), including the steps of sensing a change in a T-wave of an electrogram with respect to time such as the maximum of the first derivative of a T-wave of an electrogram; delivering a test shock by (i) delivering a test shock at a test-shock strength and at a test-shock time relating to the maximum of the first derivative of the T-wave with respect to time; and (ii) sensing for cardiac fibrillation. If fibrillation is not sensed, test-shock delivery is repeated at the same test-shock strength and at specific, different test-shock times relating to the maximum of the first derivative of the T-wave. If fibrillation is still not sensed, the shock strength is decreased and test shocks are repeated at the same specific test shock times relative to the maximum of the first derivative of the T-wave. And if fibrillation is sensed, the programmed therapeutic shock strength of the ICD is set as a function of the incrementally greater test-shock strength. Also disclosed is an apparatus for selecting a programmed first-shock strength of an ICD, including a shock subsystem for delivering therapeutic shocks and test shocks to the heart, and a ULV subsystem connected to the shock subsystem, to provide test shocks of test-shock strengths and at test-shock times relating to the maximum of the first derivative of the T-wave with respect to time, and to determine the therapeutic shock strength of the ICD as a function of the test-shock strengths.
摘要:
In medical convulsive therapy (CV), comprising electroconvulsive therapy (ECT) and magnetoconvulsive therapy (MCT), a computer system is used to analyze the effectiveness of the treatment. In one embodiment the effectiveness is determined by measuring the physiological effects on the heart (ECG) muscles (EMG) and brain (EEG).
摘要:
A method and system in electroconvulsive therapy (ECT) to automatically monitor and display the occurrence and the duration of the seizure activity generated during the administration of the electrically induced therapeutic seizures. The ECT device includes a special-purpose electroencephalograph (EEG) system to detect a specific EEG parameter (e.g. integrated voltage) of the electrically induced EEG seizure. The detected integrated voltage is converted to digital data and compared to a threshold reference value previously obtained from the same patient. The operator is informed by an electronic alphanumeric elapsed time display or indications on a moving strip chart paper record, or oscilloscope CRT screen, when the parameter has crossed the predetermined threshold reference value and how long since the termination of the ECT the parameter has taken to reach the reference value.
