Abstract
A catheter shaft is produced by forming a first polymeric layer onto a flexible inner core while maintaining the inner core in a solid state, and solidifying the first polymeric layer, wherein the solidified first polymeric layer fails to bond with the inner core and is slidable thereon upon flexion of the shaft. A second polymeric layer may be formed over the first polymeric layer, and is slidable thereon when the shaft bends.
