Abstract: A method of forming an introducer sheath having a crease-free tapered distal tip portion. A mandrel is provided having an outer configuration comprising an elongated body and a tapered distal tip portion. A generally tubular inner liner comprising heat shrinkable PTFE, is positioned over the mandrel. The inner liner is heat shrunk to the outer configuration of the mandrel, in a manner that avoids the formation of creases along the inner diameter of the liner. A reinforcing member is positioned over a length of the inner liner, and an outer jacket is positioned over the reinforcing member and the inner liner. The liner, reinforcing member, and outer jacket are heated in a heat shrink enclosure, whereby the outer jacket melts and bonds to an outer surface of the inner liner.

Abstract: A balloon catheter device (400) of the present invention includes an elongate catheter shaft (401) comprising multifilar cable tubing having a proximal portion and a distal portion. The proximal portion includes a coating that allows the shaft to provide a patent fluid passage, and a part of the distal portion inside a balloon (406) 5 may be uncoated or otherwise open to the balloon lumen, allowing for passage of fluid through the shaft into the balloon lumen.
