Abstract:
A carbon coating on a stent having a bioactive agent covalently attached thereto and methods of making the same are described. The covalent attachment may be achieved via a photo-reactive chemical or a thermo-reactive chemical. In some embodiments, the carbon coating includes a diamond-like material. The bioactive agent may be heparin or superoxide dismutase enzyme or a mimetic thereof.
Abstract:
A coating for a medical device, particularly for a drug eluting stent, is described. The coating can include a polymer having in a dry state a glass transition temperature within a range of between about 20° C. and about 55° C.
Abstract:
A method of coating an implantable medical device, such as a stent, is disclosed. The method includes applying a formulation on a first polymer layer containing a therapeutic substance to form a second layer. The formulation can contain a highly hydrophobic polymer or a solvent which is a poor solvent for the drug or the polymer of the first layer. The formulation can have a low surface tension value or a high Weber number value.
Abstract:
A method of manufacturing an implantable medical device including applying a composition to an implantable medical device, the composition including a polymer, an active agent and a solvent; allowing the solvent to evaporate to form a dry coating, the dry coating comprising less than about 2% residual fluid content (w/w); applying a fluid to the dry coating, the fluid being substantially free from any polymer; and allowing the fluid to evaporate from the coating.
Abstract:
Stents or scaffolds made from magnesium or magnesium alloys including additives or barrier coatings that modify the corrosion rate of the stent are disclosed. Methods of forming barrier coatings that modify the corrosion rate of the stent are disclosed.
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.
