Abstract
Abstract A cardioversion and defibrillation lead system and a method of use of the lead system for applying energy to the heart. The lead system and method of application are designed to maximize the efficiency of electrical energy and depolarizing the cells of the heart by equalizing current distribution across the heart and concentrating current in the muscular areas of the heart. The method of use of the lead system includes properly locating the electrodes, and applying pulses to the electrodes in one of several pulse regimes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
An epicardial electrode, comprising: a flexible member of insulative material; a plurality of elongated, flexible insulative sheets, each having a first end mounted to said member and a second, free end extending from said member, said member and said flexible insulative sheets capable of assuming a generally planar configuration; a plurality of electrodes, at least one electrode mounted to each of said plurality of flexible elongated insulative sheets; an elongated insulated electrical conductor having a distal end coupled to each of said plurality of electrodes; and an electrical connector coupled to the proximal end of said elongated insulative conductor.
Claim 2
Dependent Claim
99 words
An epicardial electrode, comprising: a flexible member of insulative material; a plurality of elongated, flexible insulative sheets, each having a first end mounted to said member and a second, free end extending from said member, said member and said flexible insulative sheets capable of assuming a generally planar configuration; a plurality of electrodes, at least one electrode mounted to each of said plurality of flexible elongated insulative sheets; an elongated insulated electrical conductor having a distal end coupled to each of said plurality of electrodes; and an electrical connector coupled to the proximal end of said elongated insulative conductor.
Claim 3
Dependent Claim
112 words
An epicardial electrode lead comprising a flexible electrode body capable of assumming a generally planar configuration comprising at least first, second and third flexible elongated members, each of said members having a fixed end coupled to the fixed ends of the others of said members and a free end spaced from the free ends of the others of said members, said electrode lead further comprising at least first, second and third electrodes, mounted to said first, second and third elongated flexible members, and an elongated, insulated conductor having a proximal end and a distal end, said first, second and third electrodes electrically coupled to the distal end of said elongated insulated conductor.
Claim 4
Dependent Claim
112 words
An epicardial electrode lead comprising a flexible electrode body capable of assumming a generally planar configuration comprising at least first, second and third flexible elongated members, each of said members having a fixed end coupled to the fixed ends of the others of said members and a free end spaced from the free ends of the others of said members, said electrode lead further comprising at least first, second and third electrodes, mounted to said first, second and third elongated flexible members, and an elongated, insulated conductor having a proximal end and a distal end, said first, second and third electrodes electrically coupled to the distal end of said elongated insulated conductor.
Claim 5
Dependent Claim
29 words
An epicardial electrode lead according to claim 2 wherein said elongated flexible members comprise flexible sheets of insulative material, upon which said first, second and third electrodes are mounted.
Claim 6
Dependent Claim
35 words
An epicardial electrode lead according to claim 2 or claim 3 wherein said first, second and third flexible elongated members are sufficiently flexible so that may be bent to generally define a cup shaped electrode.
