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 for making coatings on an implantable device such as a drug-eluting stent comprising a polymer and nano or microparticles of a drug in slow-dissolving polymorph, implantable devices produced by the methods and methods of using the coatings are provided.
摘要:
Methods of and systems for fabricating a polymeric stent with improved fracture toughness including radial expansion of a polymer tube along its entire length at the same time and fabricating a stent from the expanded tube are disclosed herein.
摘要:
A method for fabricating a coating for an implantable medical device is provided comprising applying a first polymer on at least a portion of the device to form a first layer of the coating and applying a second polymer on at least a portion of the first layer to form a second layer of the coating. The second polymer has a lower degree of hydration than the first polymer.
