Abstract
An integrated catheter tip that is fabricated to include an inflation balloon that is formed/bonded to the catheter tip as part of an initial molding operation. A tip portion of the integrated catheter tip is formed of a first high durometer polymer while the inflation balloon is formed using a second low durometer polymer. Utilizing a two-step molding operation, the first high durometer polymer can be injected to form the catheter tip and subsequently allowed to cool. Next, the second low durometer polymer is injected to form the inflation balloon and to bond the inflation balloon to the catheter tip so as to create an integrated catheter tip. Once the integrated catheter tip has been formed, the integrated catheter tip can be attached to a catheter body utilizing a conventional attachment method.
