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:
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:
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.
摘要:
A medical article is disclosed, comprising a biologically degradable AB block copolymer and a biologically degradable polymer that is capable, at equilibrium and at room temperature, of absorbing less than about 5 mass % water.
摘要:
A stent comprising a coating layer is disclosed. The coating layer has a hydrophobic component and a hydrophilic component, wherein a region of the coating layer on or about the outermost surface of the coating layer has a higher content or concentration of the hydrophilic component than the hydrophobic component.
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:
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:
Methods for modulating and enhancing thermal and mechanical properties and biocompatibilities of coatings on implantable devices are disclosed. Implantable devices containing the enhanced thermal and mechanical properties and biocompatibilities are also described. The implantable devices can be used to treat a medical condition such as vulnerable plaque or restenosis.
摘要:
Coatings for an implantable medical device and a method of fabricating thereof are disclosed, the coatings comprising a biologically degradable, biologically erodable, and/or biologically resorbable ABA or AB block copolymer. A biologically active agent can be conjugated to the block copolymer.
