Abstract
A connection system for a guidewire and a guidewire extension includes a manually actuable locking mechanism for locking or unlocking the mated ends of the wires together. One of the mating ends includes a socket. The other mating end includes a wire having a reduced diameter end portion that carries a sleeve. An enlarged wedging element is attached to the tip of the wire. The arrangement of the wedging element and sleeve are insertable into the socket and, after insertion, the arrangement is manipulated to draw the wedging element into the end of the sleeve. The sleeve thus is wedged radially outwardly into firm engagement with the inner surface of the socket. The lock is easily released by pulling the sleeve axially away from the wedging element.
