摘要:
A coating for an implantable medical device is provided comprising a first layer including a first polymer and a second layer including a second polymer. The second layer is disposed over at least a portion of the first layer. The second polymer has a lower degree of hydration than the first polymer.
摘要:
Provided herein is a PEA polymer blend and coatings or implantable devices formed therefrom. The PEA polymer blend is formed of a PEA polymer and a material capable of hydrogen bonding with the PEA. The PEA polymer blend can form a coating on an implantable device, one example of which is a stent. The coating can optionally include a biobeneficial material and/or optionally with a bioactive agent. The implantable device can be used to treat or prevent a disorder such as one of atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, and combinations thereof.
摘要:
Methods for fabricating coatings for implantable medical devices are disclosed. The coatings include hydrophilic and hydrophobic components. The methods provide for treatment of the coatings to cause enrichment a region close to, at or on the outer surface of the coating with the hydrophilic component.
摘要:
A method of manufacturing an implantable medical device, such as a drug eluting stent, is disclosed. The method includes subjecting an implantable medical device that includes a polymer to a thermal condition. The thermal condition can result in reduction of the rate of release of an active agent from the device subsequent to the implantation of the device and/or improve the mechanical properties of a polymeric coating on the device.
摘要:
Drug-delivery stents capable of providing release of two or more drugs such as everolimus and estradiol are provided. The stents can be used for treating a disease such as restenosis and vulnerable plaque.
摘要:
A poly(ester amide) (PEA) coating with enhanced mechanical and/or release rate for coating an implantable device, such as a drug-eluting stent, is disclosed. A method of forming the PEA coating onto a device and a method of treating a disorder, such as restenosis, are also disclosed.
摘要:
An implantable medical device, such as a stent, is disclosed having a coating. The coating includes a poly(butylene terephthalate-co-ethylene glycol) polymer. The coating can also include a drug.
