Bipolar temporary pacing lead and connector and permanent bipolar nerve wire
First Claim
1. A connector for connecting to the proximal end of a temporary heart lead wherein the proximal end includes a first proximal electrode (7), and a second proximal electrode with that second proximal electrode comprising a breakaway needle (6) having along its length a point of intended breaking, the connector comprising:
- a housing (16) having an entry means (15) and an exit means (20) for receiving the proximal end of said heart wire with the breakaway needle (6) in its unbroken state protruding through said exit means (20),means for holding (19) the breakaway needle (6) at its point of intended breaking, the holding means (19) being located within said housing (16) adjacent to said exit means (20), and functioning as a fulcrum about which the needle is broken,a first electrical contact means (17) for making electrical contact with said first proximal electrode (7) when the needle is held by said holding means (19),a second electrical contact means (18) for making electrical contact with said breakaway needle (6) when the breakaway needle (6) is held by said holding means (19),the first electrical contact means (17) and the second electrical contact means (18) for connection to cables (28,
29).

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 concentration of electrical energy to the nerve trunk (58) to be stimulated.
