Abstract
A tool both attaches and seals a lead to an body implantable device such as a heart pacemaker, an insulin pump, or the like. The tool includes a handle portion and a first wrench and preferably a second wrench, with each wrench being attached to the handle portion on opposite ends thereof. The first wrench extends first through a cap and then a sealing member, the sealing member preferably made of a silicone rubber. The cap is frictionally held on the first wrench preferably by a cylindrical member circumferentially engaging the cap and fixedly attached to the handle portion. A set screw is preferably detachably attached at the end of the first wrench adjacent the sealing member. To attach the lead to the device, the set screw is threadably inserted into a bore in the device positioned at a substantially right angle to a portion of the lead, and clamps the terminal pin against an inside surface of a terminal block in the device. While the set screw is being inserted within the bore, the cap which is frictionally held by the cylindrical tube is also turned into the bore. When the set screw is turned sufficiently far to attach the electrode to the device, the first wrench is withdraw…
