What is claimed is: 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
What is claimed is: 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. 2. The cardioverter-defibrillator of claim 1, wherein the width of the housing along at least a part of the second portion is greater than the width of the housing along at least a part of the shoulder region. 3. The cardioverter-defibrillator of claim 1, wherein the width of the housing along at least a part of the first portion is greater than the width of the housing along at least a portion of the shoulder region. 4. The cardioverter-defibrillator of claim 1, wherein the width of the housing along at least a part of the first portion is less than the width of the housing along at least a part of the second portion. 5. The cardioverter-defibrillator of claim 1, wherein the depth of the housing along at least a part of the first portion is less than the depth of the housing along at least a part of the second portion. 6. The implantable cardioverter-defibrillator of claim 1 further comprising a second electrode disposed on the housing, the first and second electrodes both coupled to the electrical circuit for delivering cardioversion-defibrillation energy to the patient using only electrodes disposed on the housing such that the implantable cardioverter-defibrillator lacks any lead. 7. The cardioverter-defibrillator of claim 1, wherein the electrical circuit is disposed within the second portion. 8. The cardioverter-defibrillator of claim 1, wherein the first portion includes a tapered region such that the depth of the housing within the tapered region decreases in a tapered fashion toward the first end. 9. The cardioverter-defibrillator of claim 1, wherein the bottom surface has a length and the top surface has a length, and the length of the bottom surface is greater than the length of the top surface. 10. The cardioverter-defibrillator of claim 1, wherein the electrode is a subcutaneous electrode that provides a cardioversion-defibrillation energy to a patient's heart from a subcutaneous position. 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. 12. The cardioverter-defibrillator of claim 11, wherein the housing has a depth in the distal portion of the housing in the range of about 10 to about 10millimeters. 13. The cardioverter-defibrillator of claim 11, wherein the depth of the housing in the distal portion is in the range of about 1 to about 4 millimeters. 14. The cardioverter-defibrillator of claim 11, wherein the depth of the housing in the distal portion is about 1 millimeter. 15. The cardioverter-defibrillator of claim 11, wherein the top and bottom surfaces meet at the distal end of the housing such that the depth of the distal end is tapered.
