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 wi…
