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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
