摘要:
Pro-healing agent formulation compositions, methods and treatments for enhancing vascular healing are disclosed herein. In some embodiments, a pro-healing agent is encapsulated, suspended, disposed within or loaded into a biodegradable carrier for sustained-release delivery to a denuded or damaged endothelium treatment area in a blood vessel. In some applications, the pro-healing agent can accelerate re-endothelialization of a denuded vascular region. In some applications, the pro-healing agent can assist in the regaining of endothelium functionality. The formulation can be delivered by a delivery assembly such as an infusion catheter, a porous balloon catheter, a needle injection catheter, a double balloon catheter or the like.
摘要:
A method of manufacturing a drug-delivery coating for a stent is disclosed. The method comprises covering the outer surface of the stent; applying a first composition to the inner surface of the stent to form a first coating; covering the first coating on the inner surface of the stent; and applying a second composition to the outer surface of the stent to form a second coating.
摘要:
The present invention generally encompasses a medical article, such as a medical device or coating comprising an agent or combination of agents, wherein the agent is distributed throughout a polymeric matrix. The polymeric matrix comprises an agent and a poly(ester amide) having a design that was preselected to provide a predetermined release rate of the combination of agents from the medical article.
摘要:
Various medical implants and methods of using the implants are disclosed. In an embodiment, the implants include piezoelectric polymers for treating unwanted medical conditions of a patient. The medical implants may be delivered to an organ of the patient to treat conditions of those organs.
摘要:
A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold has a pattern including an asymmetric closed cell connecting links connecting the closed cells.
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:
An apparatus for coating implantable medical devices, such as stents, and a method of coating stents using the apparatus is also disclosed. The apparatus includes a barrier or barriers for isolating an area of the stent on which a composition for coating a stent is applied. Two coating compositions can be applied simultaneously to a stent by separate nozzles on different sides of a barrier. Cross-contamination of the compositions is prevented by the barrier.
