ABSTRACT:
The present invention concerns a mechanism for securely mounting an expandable stent onto a balloon catheter for intraluminal delivery within a patient. The stent is secured to the balloon of the delivery catheter by forming the surface of the balloon to project into the interstices of the stent. To mount the stent it first is slid over an evacuated and wrapped balloon while in its compact delivery diameter. A rigid tube then is placed over the stent and balloon assembly and the balloon is pressurized while a solvent is applied to the balloon. The rigid tube prevents the stent from expanding but allows the balloon to deform so that its surface projects slightly through either or both of the interstices and ends of the stent. The solvent causes the balloon material to take a permanent set into the stent such that once pressure is removed, the stent is interlocked with the surface of the balloon. The engagement of the stent with the balloon prevents unintended axial sliding of the stent with respect to the balloon during delivery through the vessel of the patient.
