Patent number: 9039748Abstract: A method for securing an implantable medical device onto a balloon which includes applying a coating, which includes a film-forming polymer and at least one solvent, to the outer surface of the balloon. The solvents can include alcohol, water, ether and combinations thereof. The film-forming polymer can include a zwitterionic polymer, such as, for example a phosphorylcholine polymer. The coating can be applied to the entire balloon surface or a portion of the surface. The implantable medical device is then positioned on the outer surface of the balloon and secured. The film-forming polymer is then allowed to cure in order to define an adhesive layer between an inner surface of the implantable medical device and the outer surface of the balloon. This method prevents or reduces the leaching or redistribution of any therapeutic agents dispersed within or on the surface of the implantable medical device.Type: GrantFiled: April 7, 2009Date of Patent: May 26, 2015Assignee: Abbott Cardiovascular Systems Inc.Inventors: Keith R. Cromack, Donald Verlee
