摘要:
Provided herein is a poly(ester amide) (PEA) polymer blend and a polymeric coating containing the PEA polymer blend. The PEA polymer blend has a Tg above the Tg of poly(ester amide benzyl ester) (PEA-Bz) or the Tg of poly(ester amide TEMPO). 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:
The present invention relates to implantable medical devices coated with polymer having hemocompatible and/or prohealing moieties appended thereto and to their use in the treatment of vascular diseases.
摘要:
Methods are disclosed for controlling the morphology and the release-rate of active agent from a coating layer for medical devices comprising a polymer matrix and one or more active agents. The methods comprise exposing a wet or dry coating to a freeze-thaw cycle. The coating layer can be used for controlled delivery of an active agent or a combination of active agents.

An electrotransport reservoir housing which contains, integrally formed therein, at least one region of conductive material which allows for a liquid and moisture tight barrier, while at the same time providing a means for conducting an electric current therethrough.
摘要:
An iontophoretic delivery device (10) is provided. Device (10) has an electronic circuit (32) having electronic components such as batteries (30) mounted thereon. Device (10) also includes a pair of electrode assemblies (18, 19). The electronic circuit (32) is electrically connected to the electrode assemblies (18, 19) using an electrically conductive adhesive (34). The adhesive can also be used to electrically connect two or more electronic components within circuit (32) or to connect an electronic component to the electronic circuit (32). In one practice of the invention, the electrically conductive adhesive (44) functions as an electrode and electrically connects the circuit (32) to an agent-containing reservoir (24, 25). In a further practice of the invention, the electrically conductive adhesive (93) functions as an agent reservoir and contains the agent to be iontophoretically delivered.
