摘要:
A defibrillator paddle includes a pediatric electrode of relatively small size attached to a mounting portion of a housing having a handle. An adult electrode assembly is releasably mounted to the mounting portion of the housing by a quick release latch mechanism. The adult electrode assembly includes an adult electrode larger than the pediatric electrode. The pediatric electrode nests within the adult electrode assembly and a spring makes electrical contact between the electrodes when the adult electrode assembly is mounted.

There is disclosed a self-protective system for administering an electrical shock to a would-be assailant by first establishing a low resistance path to the nervous system of the assailant and then coupling thereto an interference signal voltage having a frequency within the passband of the nerves. It incorporates a novel compact power oscillator which is normally quiescent until applied to a load, to produce, under load, a waveform which has a unique application to self-protective devices and medical uses. The oscillator includes a high gain inverting amplifier, preferably a Darlington pair constituted by a germanium output transistor driven by a small signal transistor, a transformer, a D.C. source such as a battery, and a pair of output electrodes.

Methods and means for assisting persons in breaking undesirable habits include means for projecting first and second images onto a screen. The first image is a fixation image to induce a person to concentrate in a small limited area. The second image relates to an object or message relating to the habits to be broken. Various additional sensory messages, such as electrical or audio signals, are communicated to the person while one or both of the images are being projected on the screen.

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.

An implantable medical device (IMD) 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 IMD's lead system when implanted in a patient. The output switching circuitry may be configured to facilitate self-test mode (STM) functionality in the IMD (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.
摘要:
An ECT system capable of focusing the electrical signals on a specific portion of the patient's brain is provided. The ECT system includes a means of applying unidirectional electrical signals and asymmetric electrodes for focusing the signals on the patient. A method of titrating an electro-convulsive therapy (ECT) system and a method of operating an ECT system are also provided. The method includes setting an initial current value, administering an ECT signal to the patient, determining if the seizure threshold has been achieved, and repeating as necessary until the seizure threshold is achieved.
