摘要： A defibrillation electrode for implantation on or about the heart and for connection to a defibrillation system. The electrode comprises a plurality of electrically conductive elements spaced apart and electrically connected together, thus, increasing the number of discharging edges on the electrode. In a first embodiment, the electrode comprises a plurality of concentric conductive rings electrically connected together. In a second embodiment, electrode comprises a plurality of conductive planar elements electrically connected together in a generally puzzle-like configuration. In a third embodiment, the electrode comprises electrically conductive wires wrapped around the length of a cardiac catheter. In a fourth embodiment, electrically conductive wires are concentrically spiralled into a spiral patch configuration. In a fifth specific embodiment, a plurality of electrically isolated active sites are provided on the distal portion of an endocardial catheter. In all of the above embodiments, the electrical discharge of energy from the electrode to the heart surface favors the conductive edges of the electrically conductive and connected components of the electrodes. Therefore, by increasing the number of conductive edges, a more uniform distribution of energy is delivered to the heart. Furthermore, each of the electrode configurations may be constructed without an insulative backing to further increase the efficiency of discharge.

摘要： An implantable cardioverting system wherein a cardioverting or defibrillating voltage is automatically applied across implantable electrodes associated with the heart of a patient. The cardioverting voltage is an exponentially-decaying voltage pulse that is chopped, or broken, at high frequencies to provide a voltage wave packet formed of a plurality of high-frequency cardioverting pulses. The voltage is provided by an internal storage capacitor coupled across implantable electrode leads that is charged to a predetermined voltage level. Upon discharge, an electronic switch is clocked at frequencies preferably in excess of 1 KHz to open and close the circuit formed of the storage capacitor and electrodes.

摘要： The invention relates to an arrhythmia detection system and method for defibrillating the heart of a patient experiencing abnormal cardiac rhythm, wherein the abnormal cardiac rhythm (comprising one of fibrillation, high rate tachycardia, and low rate tachycardia) is first detected, the heart rate is sensed so as to distinguish between fibrillation and high rate tachycardia, on the one hand, and low rate tachycardia, on the other hand, and automatic defibrillation of the heart of the patient is implemented when one of fibrillation and high rate tachycardia is determined. In one embodiment, base and apical electrodes are connected to a probability density function (PDF) circuit and a rate circuit. When both abnormal cardiac rhythm and excessively high heart rate are detected, defibrillation of the heart of the patient is implemented. In a second embodiment, a sensing button is also connected to the heart, and a switch is interposed between the electrodes and sensing button, on the one hand, and the interface, on the other hand. During monitoring of cardiac rhythm by the PDF circuit, the switch automatically connects the electrodes to the PDF circuit, while, during sensing of the heart rate, the switch connects the sensing button to the heart rate circuit. Upon detection of the need for defibrillation, the switch automatically connects the defibrillation pulse generator to the electrodes. Further features include a timed reset capability.

摘要： A fluid-tight electrical coupling for a medical device fully implantable in the body of a recipient, such as an implantable defibrillator, is disclosed. The fluid-tight coupling is mounted on a hermetically sealed casing. The coupling comprises a housing having receptacles for receiving an electrical conductor plug. Terminal blocks are provided within the housing and define a pin opening for receiving the pins of the electrical conductor plug. The terminal block is electrically connected to the exterior of the housing. The terminal block also includes a cylindrically shaped boss extending from a face of the terminal block. The boss is externally and internally threaded for receiving a sealing cap and a retaining member respectively. The retaining member comprises a hexagonal socket head set screw. The sealing cap seals off the interior of the housing. The sealing cap is secured to the terminal block to seal off the housing opening by means of a screwdriver that is adapted to retain the sealing cap thereto. Also disclosed is a maximum torque wrench to prevent overtightening of the set screw.
