Implantable cardiac stimulus methods
First Claim
Patent Images
1. A method of treating a patient comprising:
- providing an implanted cardiac stimulus system having a canister and a lead assembly, the system being provided such that it does not contact or enter the heart;
detecting cardiac activity by capturing electrical signals from the heart using electrodes which do not contact or enter the heart;
determining whether cardiac stimulus appears to be indicated; and
, if so,delivering cardiac stimulus using electrodes which do not contact or enter the heart, the cardiac stimulus having a peak amplitude in the range of 25-50 volts.

Abstract
A power supply for an implantable cardioverter-defibrillator for subcutaneous positioning between the third rib and the twelfth rib and using a lead system that does not directly contact a patient'"'"'s heart or reside in the intrathoracic blood vessels and for providing anti-bradycardia pacing energy to the heart, comprising a capacitor subsystem for storing the anti-bradycardia pacing energy for delivery to the patient'"'"'s heart; and a battery subsystem electrically coupled to the capacitor subsystem for providing the anti-bradycardia pacing energy to the capacitor subsystem.

16. A method of treating a patient comprising:
-
providing an implantable cardiac stimulus system consisting of; a) a canister housing operational circuitry and a battery; b) a lead assembly consisting of a single elongate member coupled to the canister at a first end thereof and having a plurality of electrodes disposed at or near a second end thereof, with a plurality of electrical conductors extending therein; implanting the implantable cardiac stimulus system into a patient such that neither the canister nor the lead electrode assembly touches or enters the heart or resides in an intrathoracic blood vessel; detecting cardiac activity by the observation of electrical signals generated in the patient'"'"'s heart; determining whether cardiac stimulus appears to be indicated; and
, if so,delivering cardiac stimulus. - View Dependent Claims (17, 18, 19, 20, 21)
