BALLOON CATHETER AND METHOD OF MANUFACTURE

摘要

A method of manufacturing a balloon catheter in which an extruded tubular balloon parison is attached to a component of a catheter shaft prior to blow molding a balloon from the extruded tubular balloon parison. A distal end region of the tubular balloon parison is attached to the outer surface of the elongate catheter shaft component to form a distal bond region between the tubular balloon parison and the catheter shaft component, and then the assembly is positioned in a balloon mold. An annular space between an inner surface of the tubular balloon parison and the outer surface of the elongate tubular member is pressurized to expand the tubular balloon parison in the cavity of the balloon mold to form an inflatable balloon.

1. A method of manufacturing a balloon catheter, comprising:
attaching a first end region of a tubular balloon parison to an outer surface of an elongate tubular member of a catheter shaft to form a first bond region between the tubular balloon parison and the elongate tubular member of the catheter shaft; positioning the tubular balloon parison and the elongate tubular member in a balloon mold with the first bond region positioned in a cavity of the balloon mold; pressurizing an annular space between an inner surface of the tubular balloon parison and the outer surface of the elongate tubular member to expand the tubular balloon parison in the cavity of the balloon mold to form an inflatable balloon; removing the inflatable balloon and the elongate tubular member from the balloon mold; and attaching a waist of the inflatable balloon to the catheter shaft.
