Patent Images
1. An epicardial implantable defibrillator lead comprising:
- a loop system having a first end and a second end, the loop system comprising a sensor, a coil, and a closure segment comprising a perforation member and a sleeve;
the coil comprising a generally tubular conductive portion defining a lumen, the lumen comprising an insulator, the insulator enclosing a conductor member, a memory member, or both;
the sensor, coil, perforation member and sleeve being coupled in linear arrangement with the perforation member located proximal to the first end and the sleeve located proximal to the second end; and
a connector system having a first end and a second end, the first end of the connector system coupled to the second end of the loop system, the second end adapted to be coupled to a pulse generator, the connector system comprising an insulating cover enclosing a conductor;
the conductor passing through the connector system and connecting with either the coil or sensor.
