Abstract: A stent delivery catheter system having a catheter with stent releasably mounted on a stent retention portion of the catheter for delivery and deployment within a patient's body lumen, and a method of mounting the stent on the stent retention portion of the catheter. The method generally includes exposing the stent retention portion and/or the stent to a solvent, the solvent being in the vapor phase. The vapor phase solvent typically softens the stent retention portion of the catheter, and/or, in one embodiment in which the stent has a coating on the stent body, the vapor phase solvent softens the stent coating. In a presently preferred embodiment, the stent polymeric coating has a therapeutic agent, and the method of the invention prevents or inhibits disadvantageously affecting the therapeutic agent coating during mounting of the stent on the catheter.
