ABSTRACT:
The extension wire for a fixed balloon on a guidewire comprises a length of extension wire and a connector assembly mounted on the distal end of the length of extension wire. The connector assembly includes a tube which is received on and fixed to a distal end of the length of extension wire and which has means within the tube for grippingly engaging an outer covering sheath of a cut proximal end of the sheath and core wire of a fixed balloon on a guidewire.
The fixed balloon on a guidewire extension wire assembly kit includes the extension wire and connector assembly at the distal end of the extension wire, and an alignment tool having a body and a throughbore adapted to receive the tube of the connector assembly at the distal end of the extension wire in one end thereof and the cut proximal end of a fixed balloon on a guidewire in the other end for guiding the cut end into the tube of the connector assembly.
The method for extending an initially inserted fixed balloon on a guidewire having a strong relief sheath and a hub at the proximal end thereof comprises the steps of:
providing an extension wire with a connector assembly at a distal end thereof, the connector assembly including a tube fixed to the distal end of the extension wire,
providing gripping means within the tube;
cutting the strain relief sheath and hub from the proximal end of an initially inserted fixed balloon on a guidewire; and
inserting the cut proximal end of the fixed balloon on a guidewire including a core wire and a surrounding sheath into the tube of the connector assembly to cause the gripping means therein to grippingly engage the sheath at the cut proximal end of the fixed balloon on a guidewire.
