  • Single pass lead system
    Patent number: 6212434
    Abstract: A single-pass endocardial lead electrode adapted for implantation in, on or about the heart and for connection to a system for monitoring or stimulating cardiac activity includes a lead body which is adapted for implantation within a single chamber of the heart, or multiple chambers of the heart. The lead includes a first distal end electrode which has a first electrical conducting surface. The lead body also has a second electrode which has a second electrical conducting surface. The first and second electrodes are either passively or actively attached to the wall of the heart. The lead body also includes a curved portion which facilitates the positioning of the second electrode. The main lead body alternatively includes a recess into which an atrial lead body and an active fixation element attached to one end can travel from a recessed position to a position for fixation to the wall of the heart. The active fixation element can also be moved by turning the terminal pin.

  • Method and apparatus for treating cardiac arrhythmia using electrogram features
    Patent number: 6112117
    Abstract: A method and system for ventricular defibrillation by coordinating the delivery of defibrillation shocks with sensed ventricular fibrillation complexes in a way which improves the probability of success of the defibrillation shock. Ventricular electrical activity is monitored in two ventricular locations during ventricular fibrillation to detect coarse ventricular fibrillation complexes and contractions of the ventricular cardiac tissue. The defibrillation shock is delivered in coordination with the occurrence of coarse ventricular fibrillation complexes and the contractions of ventricular cardiac tissue, and specifically to occur on the up-slope portion thereof, for optimal probability of success.

  • Ventricular defibrillation by coordination of shocks with sensed coarse VF complexes
    Patent number: 5632766
    Abstract: A method and system for ventricular defibrillation by coordinating the delivery of defibrillation shocks with sensed ventricular fibrillation complexes in a way which improves the probability of success of the defibrillation shock. Ventricular electrical activity is monitored during VF to detect coarse VF complexes. The defibrillation shock is delivered in coordination with the occurrence of coarse VF complexes, and specifically to occur on the upslope portion thereof, for optimal probability of success. Preferably, DF shock is delivered on the nth occurring coarse VF complex, wherein n is equal to or greater than 2 and less than or equal to about 9.
