Abstract
A temporary heart wire, and external connector therefore, and the combination of the two, wherein the distal end of the heart wire includes a temporary affixation coil (8) and distal pacing (2) and sensing (1) electrodes connected by means of a coaxial helicoidally wound cable (3) to a proximal electrode (7) and a breakaway needle (6) which also serves as a proximal electrode. The lead is adapted to be inserted into a disposable connector having a snap aperture element (19) for receiving the breakaway needle, and about which the needle is broken, as well as electrical contacts (17, 18) for contacting the proximal electrodes and adapted to be connected to a temporary external pacemaker. In an alternate embodiment, there is provided a permanent bipolar nerve electrode which includes two electrodes (52), (54) adapted to be positioned along the nerve trunk (58). The bipolar nerve electrode further includes an affixation coil (56) and a thin insulation layer or flap (57), this latter being adapted to be sutured to the surface of the patient's muscle to thereby preclude or limit stimulating electrical energy to be transmitted to adjacent muscles, this allowing for a more focused concentr…
