Method of manufacturing a catheter assembly

摘要

A catheter assembly includes a catheter having a proximal end and a distal end; an expandable device releasably attached to the catheter near the distal end; a generally tubular constraining sleeve extending around and compressing the device to an outer peripheral dimension suitable for endoluminal delivery; a tip fixedly secured to the distal end of the catheter; and a bridge member disposed between the tip and the expandable device so as to fill a gap therebetween as the catheter assembly is bent during endoluminal delivery of the expandable device to a treatment site.

1. A method of manufacturing a catheter assembly including:
providing a catheter having a distal end and an expandable device fixedly secured thereto; providing a bridge member generally coaxial with the catheter and disposed onto an exposed portion of the distal end of the catheter; providing a tip generally coaxial with the catheter and disposed onto the exposed portion of the distal end of the catheter; axially compressing the bridge member between the expandable device and the tip; and fixedly securing the tip to the catheter to retain the bridge member in the compressed state between the expandable device and the tip.
