1. An implantable cardioverter-defibrillator comprising:
- a housing having a top surface and a bottom surface, a first end and a second end, a first side and a second side, a depth extending between the top and bottom surfaces, a length extending between the first and second ends, and a width extending between the first and second sides, the housing including a first portion ending at the first end, which is rounded and unconnected to any implantable lead assembly, and a second portion connected together by a tapered shoulder region such that the width of the housing within the shoulder region decreases in a tapered fashion toward the first end;
an electrical circuit disposed within the housing, wherein the electrical circuit provides cardioversion-defibrillation energy to a patient; and
an electrode located on the first portion of the housing, wherein the electrode is electrically coupled to the electrical circuit.

11. An implantable cardioverter-defibrillator comprising:
-
a housing having a top surface and a bottom surface, proximal and distal ends, and first and second sides, a depth extending between the top and bottom surfaces, a length extending between the proximal and distal ends, and a width extending between the first and second sides, the housing including a distal portion and a proximal portion, wherein the width and depth of the housing within at least a part of the distal portion are less than the width and depth of the housing within at least a part of the proximal portion; an electrical circuit disposed within the housing, wherein the electrical circuit provides cardioversion-defibrillation energy to a patient; and an electrode located on the distal portion of the housing, wherein the electrode is electrically coupled to the electrical circuit and the distal portion of the housing terminates in a rounded end that is unconnected to any lead assembly. - View Dependent Claims (12, 13, 14, 15)
