The housing of the present invention can be made out of titanium alloy or other presently preferred ICD designs. It is contemplated that the housing is also made out of biocompatible plastic materials that electronically insulate the electrodes from each other. However, it is contemplated that a malleable canister that can conform to the curvature of the patient's chest will be preferred. In this way the patient can have a comfortable canister that conforms to the unique shape of the patient's rib cage. Examples of conforming ICD housings are provided in U.S. Pat. No. 5,645,586, the entire disclosure of which is herein incorporated by reference. In the preferred embodiment, the housing is curved in the shape of a 5th rib of a person. Because there are many different sizes of people, the housing will come in different incremental sizes to allow a good match between the size of the rib cage and the size of the USICD. The length of the US-ICD will range from about 15 to about 50 cm. Because of the primary preventative role of the therapy and the need to reach energies over 40 Joules, a feature of the preferred embodiment is that the charge time for the therapy, intentionally be relatively long to allow capacitor charging within the limitations of device size.
A “spade” shaped electrode 236 is depicted in FIG. 23A. The distal end of the spade shaped electrode also generally follows the outline of the rounded distal end 234 of the canister housing 220. As the spade shaped electrode 236 moves proximally along the length of the canister housing 220, the conductive surface terminates in a rounded proximal end. Similar to the thumbnail embodiment described above, the spade shaped electrode's conductive surface is generally contained within the distal end 234 of the canister housing 220. In alternate embodiments, the spade shape electrode's conductive surface may extend proximally further over or within the canister housing 220. In yet another spade shaped electrode 234 embodiment, the margins of the spade shaped electrode's conductive surface refrain from following the exact rounded contour of the canister housing 220, but substantially form a spade shaped configuration.
The electrode 268, shown in phantom, is generally positioned at either the distal end 264 or the proximal end 266 of the canister housing 260. In alternative embodiments, the tongue depressor-shaped canister housing 260 may include two or more electrodes 268. When two electrodes are utilized, one. electrode is positioned at the distal end 264 of the canister housing 260 while the second electrode is positioned at the proximal end 266 of the canister housing 260.
[0166]FIG. 26B shows the distal segment 282 of the multisegment canister housing 280 being curved to mimic the anatomical shape of a patient recipient's ribcage 216. In the embodiment depicted, both the top surface 292 and the bottom surface 294 of the proximal segment 282 are curved. The curvature, however, differs at the distal most end 288 of the distal segment 282. At the distal segment's distal most end 288, the distal segment's top surface 292 tapers downwardly toward the distal segment's bottom surface 294. This tapering causes the distal most end 288 of the distal segment 282 to be narrower than the distal segment's distal end 296. In certain embodiments, this tapering in depth may be gradual throughout the length of the distal segment 282, or alternatively, the tapering may be confined to a particular area.
[0175]FIG. 28 illustrates an alternative S-ICD canister according to an embodiment of the present invention. S-ICD canister 500 comprises a housing divided into a distal segment 510 and a proximal segment 512. A distal electrode 514 is integrally disposed on the distal housing segment 510 and a proximal electrode 516 is integrally disposed on the proximal housing segment 516. In an embodiment, the distal electrode 514 and the proximal electrode 516 are used for both sensing and shocking purposes. In an embodiment, the housing segments 510 and 512 can comprise a mixture of titanium and ceramic materials. Because of the inherent conductive properties of titanium, housing segments 510 and 512, which have integral electrodes 514 and 516 disposed therein, are insulated from each other by a distal insulating wall or plate 518. The insulating plate 518 is disposed at an end of the distal housing segment 510 opposite the distal electrode 514. In an embodiment, the insulating plate 518 can comprise a ceramic material. A distal conductive wall or plate 520 is disposed abutting the distal insulating plate 518. In an embodiment, the conductive wall 520 comprises titanium or other metals such as stainless steel, or cobalt chromium alloys. A proximal insulating wall or plate 524 is disposed at an end of the housing segment 512 opposite the proximal electrode 516 and a proximal conductive wall or plate 522 is disposed abutting the proximal insulating plate 524. In an embodiment, proximal conductive plate 522 also comprises titanium or other suitable metals such as stainless steel, or cobalt chromium alloys. Proximal insulating plate 524 can comprise a ceramic material. In an embodiment, conductive plates 522 and 520 are coupled to each other. Therefore, the two electrodes may be disposed on the same housing and used as part of a unitary device. It should be noted that according to alternative embodiments of the present invention, an S-ICD canister may have a housing comprising a titanium mixture masked with paralene or another material suitable for applications in implantable devices with a single electrode integrally disposed at one end.
