Assembly of an extension guidewire and an alignment tool for same
First Claim
1. An assembly of an extension wire and an alignment tool for aligning the proximal end of a medical catheter wire with connecting means at the distal end of said extension wire or at the proximal end of the medical catheter wire, said alignment tool comprising a body having (a) enlarged end portions, (b) a smaller-in-cross-section middle portion so that said large end portions define abutment means facing inwardly of said body toward said middle portion, and (c) passage means extending through said body along a longitudinal axis of said body and including a middle, generally cylindrical portion of substantially uniform diameter and first and second inlet means for receiving and guiding into each end, respectively, of said passageway and into said middle portion both the proximal end of a medical catheter wire or the distal end of said extension wire and the connecting means at the distal end of the extension wire or at the proximal end of the medical catheter wire, each of said inlet means at each end of the passage means of the alignment tool extending along the longitudinal axis and including an outwardly opening passage opening onto one of two opposite end faces of the body, and the body of the alignment tool being generally cylindrical in shape with the middle cylindrical portion of uniform diameter and with the opposite end faces facing outwardly and each lying in a plane generally normal to the longitudinal axis, the enlarged end portions comprising generally frusto-conical end portions each tapering or flaring radially outwardly from one of the end faces and axially toward the other end portion to an axially facing annular surface extending radially outwardly from the middle uniform diameter portion, the axially facing annular surfaces defining the abutment means.

Abstract
The alignment tool is used to align the proximal end of a medical catheter wire with connecting means at the distal end of an extension wire. The alignment tool comprises a body having passage means therethrough including first and second inlet means for receiving and guiding into each end, respectively, of said passageway the proximal end of the medical catheter wire and the connecting means at the distal end of the extension wire. The alignment tool is preferably mounted in an extension wire dispensing assembly including means for receiving and holding a length of extension wire and a holder mounted to the dispensing means and having means for receiving and holding the alignment tool. The dispensing means include a coiled tube.
