Guide wire extension peg and hole with 90 degree latch
First Claim
1. A guide wire extension assembly for angioplasty including a guide wire and an extension wire to facilitate exchanging a balloon dilatation catheter comprising:
- (a) a guide wire having a proximal end, a distal end and a radius;
(b) an extension wire having a proximal end, distal end and a radius;
(c) a first connector member and a second connector member;
(d) the first connector member being mated to one end of the guide wire comprising at least one horizontal surface extending along or parallel to the horizontal axis of the first connector member from the mated end to the opposed end, a longitudinally upwardly curved outer surface connecting the longitudinal sides of the horizontal surface or surfaces and extending from the mated end to the opposed end having the same radius as the guide wire and a first connection means located near the center of the horizontal surface; and
(e) the second connector member being mated to one end of the extension wire, the second connector member comprising a horizontal surface extending along the horizontal axis from the mated end to the opposed end, a longitudinally downwardly curved outer surface connecting the longitudinal sides of the horizontal surface and extending from the mated end to the opposed end having the same radius as the extension wire and a second connection means located near the center of the horizontal surface that is complementary and connectable with the first connection means such that when the first connection means and the second connection means are vertically connected the guide wire and extension wire are joined together.

Abstract
A guide wire extension assembly for angioplasty comprising a guide wire and an extension wire that utilize a peg and hole connection. The proximal end of the guide wire and the distal end of the extension wire have connector members attached that allow for mating the ends of the guide wire and extension wire together. In one embodiment the first connector member has a horizontal surface with a hole that is perpendicular to the horizontal surface. The second connector member has a horizontal surface with a peg extending upwardly from the horizontal surface, such that when the first connector member and the second connector member are joined, the peg and the hole fit together. In another embodiment, the first connection member and the second connection member are made from magnetic material so that when the peg is inserted in the hole, it is held in place by magnetic attraction. In another embodiment, the first connector member has a horizontal surface with a longitudinal slot that is perpendicular to the horizontal surface and extends through the first connection member. The second connector member has a horizontal surface with a peg extending upwardly from the horizontal surface with a latch on the end, the latch being dimensioned to be complementary to the slot, such that the latch fits through the slot and when the connection members are rotated away from each other, the latch locks the members together.
