摘要:
An apparatus and method for controlling inflation pressure, pressurization rate, and volumetric flow rate of a balloon during deployment of a stent or scaffold is disclosed.
摘要:
Methods and systems for controlling the moisture content of biodegradable and bioresorbable polymer resin during extrusion above a lower limit that allows for plasticization of the polymer resin melt and below an upper limit to reduce or prevent molecular weight loss are disclosed. Methods are further disclosed involving plasticization of a polymer resin for feeding into an extruder with carbon dioxide and freon.
摘要:
Methods are disclosed to improved adhesion of polymer coatings over polymer surfaces of stents which include plasma treatment, applying an adhesion promoting layer, surface treatments with solvents, and mechanical roughening techniques.

摘要:
Various embodiments of the present invention include implantable medical devices such as stents manufactured from polymers, and more particularly, biodegradable polymers including biodegradable polyesters. Other embodiments include methods of fabricating implantable medical devices from polymers. The devices and methods utilize one or more stabilizers, where each stabilizer may be chosen from the following categories: free radical scavengers, peroxide decomposers, catalyst deactivators, water scavengers, and metal scavengers.
