Abstract: An implantable medical device, and more particularly a fully implantable defibrillator which may also include bradycardia and cardioversion pacing, in which the components of the device are housed within an implantable casing having three orthogonal dimensions of height, width and thickness. The height and width are substantially greater than the thickness. The implantable device comprises three major sub-systems, specifically, the batteries, the power capacitors, and the electronics. Each of the three sub-systems lie in parallel height-width planes, each plane being adjacent another in the thickness dimension.

Abstract: A connector system for use in coupling an implantable electrical lead to an implantable pulse generator, or other implantable electrical apparatus. The connector system includes a connector pin assembly, typically mounted to the implantable lead and a connector block, typically mounted to the electrical stimulator. The connector block is provided with a lumen, in which a plurality of resilient, elastomeric rings are linearly arranged. The rings are so sized as to frictionally engage a connector pin which is provided with a plurality of conductive pads, each coupled to a conductor within the implantable lead. Certain ones of the elastomeric rings are conductive, and engage with the conductive pads on the connector pin. Others of the rings are nonconductive and act as insulators and fluid seals. The connector pin assembly is also provided with a circumferential groove, which interlocks with the deflectable beam members of a retainer mounted to the connector block.

Abstract: A clutch mechanism for use in the drive mechanism for a vacuum cleaner floor cleaning rotary brush is provided which prevents damage to the drive belt in the event the brush becomes jammed and is prevented from rotating. A cam ring having external bumps carried on resilient beams is nested inside a driven sprocket with the bumps positioned in valleys between ridges formed on the interior of the sprocket. A pair of end caps sandwich the assembly of the cam and sprocket. The cam is keyed to the rotary brush and thus when the brush becomes jammed, the sprocket will continue to rotate, and the torque applied between the sprocket and cam will cause the ridges to push radially inwardly against the bumps and beams of the cam permitting the bumps to pass over the ridges dissipating the energy of the rotating sprocket.
