Abstract

A method is provided for mounting a stent onto a catheter system. The method includes selecting a catheter having a first end where the first end includes an inflatable portion thereat. An adhesive bond is formed between the stent and the inflatable portion causing the stent to adhere to the inflatable portion. The formed adhesive bond is such that upon release of the stent from the inflatable portion upon inflation, the adhesive bond remains with the inflatable portion.

Claims

1. A method for mounting a stent onto a catheter system, the method comprising:

selecting a catheter having a first end including an inflatable portion; and

forming an adhesive bond between the stent and the inflatable portion causing the stent to adhere to the inflatable portion,

said formed adhesive bond being such that upon release of said stent from the inflatable portion said adhesive bond remains with the inflatable portion.

2. The method according to claim 1, wherein the adhesive connection comprises adhesive forces between the stent and the inflatable portion which are less powerful than shear forces applied by the inflatable portion such that the stent is releasably attached to the inflatable portion.

3. The method according to claim 1, wherein the catheter is a balloon catheter and the stent is formed of one or more metal threads or an expandable tubular member with perforations.

4. The method according to claim 1, wherein the inflatable portion is made up of a elastically deformable material.
