Abstract: The present invention includes an improved configuration and method of forming an inflatable silicone balloon on a cured silicone catheter that does not require a release agent to free the balloon from the catheter. The method includes a catheter having an inflation lumen therein and an inflation port on the distal end thereof communicating the inflation lumen with the outer surface of the catheter within the interior of the balloon, comprising the following steps:Providing a substantially cured silicone compound sleeve having an inner diameter corresponding to the outer diameter of the catheter and having a length corresponding to the desired length of the inflatable balloon. Positioning the sleeve onto the distal end of the catheter and centered on the inflation port. Overdipping the distal end of the catheter and the sleeve into an uncured silicone dispersion compound to a depth of about 0.25 inches beyond the sleeve, forming an uncured silicone compound layer over the catheter and the sleeve.
