Abstract
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.

Claim 3
Dependent Claim
40 words
The extension wire assembly of claim 1 wherein said gripping means comprises teeth forming detents punched inwardly into the tube and having teeth points extending angularly radially inwardly and axially toward the distal end of said length of extension wire.
Claim 4
Dependent Claim
171 words
A guidewire extension wire assembly kit for connecting to a fixed balloon on a guidewire which has a sheath, a core wire in the sheath and a balloon at a distal end of the sheath, said kit comprising an extension wire assembly including a length of extension wire, a connector assembly at the distal end of said extension wire, said connector assembly including a tube, which has a portion at one end received on and fixed to the distal end of said extension wire and which has gripping means extending inwardly within said tube for grippingly engaging the outer sheath of a cut proximal end of the fixed balloon on a guidewire, and an alignment tool including a body and a throughbore adapted to receive said tube of said connector assembly at said distal end of said extension wire in one end thereof and the cut proximal end of the fixed balloon on a guidewire in the other end for guiding said cut and into said tube of said connector assembly.
Claim 5
Dependent Claim
171 words
A guidewire extension wire assembly kit for connecting to a fixed balloon on a guidewire which has a sheath, a core wire in the sheath and a balloon at a distal end of the sheath, said kit comprising an extension wire assembly including a length of extension wire, a connector assembly at the distal end of said extension wire, said connector assembly including a tube, which has a portion at one end received on and fixed to the distal end of said extension wire and which has gripping means extending inwardly within said tube for grippingly engaging the outer sheath of a cut proximal end of the fixed balloon on a guidewire, and an alignment tool including a body and a throughbore adapted to receive said tube of said connector assembly at said distal end of said extension wire in one end thereof and the cut proximal end of the fixed balloon on a guidewire in the other end for guiding said cut and into said tube of said connector assembly.
Claim 6
Dependent Claim
52 words
The kit of claim 3 wherein said gripping means inside said tube comprises at least two (2) teeth forming detents which are punched in from the outer surface of said tube so as to form teeth extending radially inwardly within the tube and pointing toward said distal end of said extension wire.
Claim 7
Dependent Claim
20 words
The kit of claim 3 wherein said throughbore in said alignment tool body tappers radially outwardly at each end thereof.
Claim 8
Dependent Claim
60 words
The kit of claim 3 wherein said alignment tool body is generally cylindrical and said throughbore includes a tapered end portion which opens onto one axial end surface of said alignment tool body, (b) a uniform diameter portion and (c) a tapered portion which extends axially and radially outwardly to an opposite axial end surface of said alignment tool body.
Claim 9
Dependent Claim
21 words
The kit of claim 3 wherein said alignment tool body is generally cylindrical in shape and has an axially extending flat.
Claim 10
Dependent Claim
10 words
The kit of claim 3 further including a cutting tool.
