Abstract:
Methods for fabricating a polymeric stent with improved fracture toughness including radial expansion of a polymer tube and fabricating a stent from the expanded tube are disclosed. The polymer tube is disposed within a mold and may be heated with radiation. The heated tube radially expands within the mold.
Abstract:
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.
Abstract:
The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix that include designing and creating a predetermined initial morphology (IM) profile in a polymeric matrix. The teachings indicate, inter alia, that control over the release rate of agents can provide for an improved control over the administration of agents as well as have an effect upon the mechanical integrity and absorption rate of the polymeric matrix.
Abstract:
A polymer comprising phospholipid moieties and a biocompatible polymer backbone, a composition comprising the polymer and optionally a bioactive agent, an implantable devices such as a DES comprising thereon a coating comprising the polymer and optionally a bioactive agent, and a method of using the device for the treatment of a disorder in a human being are provided.
Abstract:
Medical devices having a catalyst capable of catalyzing the generation of nitric oxide in vivo and methods of treating a vascular condition using the devices are provided.
Abstract:
Coatings for an implantable medical device and a method of fabricating thereof are disclosed, the coatings comprising polymers of lactic acid.
Abstract:
Methods for making coatings on an implantable device, such as a drug-eluting stent. The coatings comprise a polymer and a drug in a crystalline or partially crystalline form. In addition, implantable devices produced by the methods and methods of using the coated implantable devices are described.
