| 20080241218 | Coated medical devices for abluminal drug delivery - The invention relates generally to an implantable medical device for delivering a therapeutic agent to the body tissue of a patient, and a method for making such a medical device. In particular, the invention pertains to an implantable stent, such as an intravascular stent, having a coating comprising an inorganic or ceramic oxide, metal or inert carbon and a plurality of reservoirs in such material that contain a therapeutic agent. | 10-02-2008 |
| 20080243231 | Medical device with a porous surface for delivery of a therapeutic agent - The present invention is generally directed to implantable medical devices for delivering therapeutic agents to the body tissue of a patient and methods for making such medical devices. In particular, the present invention is directed to implantable medical devices, such as intravascular stents, having a surface that includes a plurality of cavities and a plurality of pores and a composition disposed in the pores and/or cavities, as well as, implantable medical devices, such as intravascular stents, having a surface that has a coating composition disposed on the surface, wherein the coating composition includes a plurality of cavities and a plurality of pores and another coating composition disposed in the pores and/or cavities. | 10-02-2008 |
| 20080281409 | STENTS WITH DRUG ELUTING COATINGS - Provided is a coated medical device (e.g., a stent) comprising one or more surfaces having dispersed thereon a plurality of microparticles comprising an active pharmaceutical ingredient (API) and a polymer. Specifically, the microparticles are disposed on a device surface in a microparticulate phase coating, i.e., as discrete microparticles in the absence of a continuous phase coating. The medical device effectively adheres one or more APIs to its surface, and allows controlled release of the APIs from the device surface to a desired treatment area by using a minimal amount of polymer. The medical device is suitable for insertion or implantation into a subject, preferably a human. Also provided are methods for preparing and using the coated medical device. | 11-13-2008 |
| 20090035448 | MEDICAL DEVICE COATING BY LASER CLADDING - Methods for making medical devices having porous coatings. Methods may comprise providing a tubing section having inner and outer surfaces and positioning a nozzle proximate to a target surface of the parent tubing section. A powder form of the porous coating may be delivered toward the tubing section, and a laser may be directed at the powder to melt the powder to form a melt pool. The melt pool can solidify to form the porous coating on the target surface. Portions of the parent tubing section may then be cut away to form the support structure of the medical device, such as a stent. | 02-05-2009 |
| 20100015206 | MEDICAL DEVICES HAVING METAL COATINGS FOR CONTROLLED DRUG RELEASE - Medical devices having a plurality of nanoparticles disposed over a surface of the medical device. The nanoparticles have a core comprising a therapeutic agent and a shell surrounding the core, wherein the shell comprises a metal. A barrier layer is disposed over the nanoparticles. The barrier layer is water-permeable and comprises a metal that may be different from the metal used in the nanoparticle shells. In certain embodiments, the metal in the barrier layer undergoes galvanic corrosion. Also disclosed are medical device having a reservoir containing a therapeutic agent, with nanoparticles and a barrier layer being disposed over the reservoir; and medical devices having multiple barrier layers and multiple reservoirs containing therapeutic agents. | 01-21-2010 |
| 20100125328 | BIOABSORBABLE STENT - A medical device includes a support structure formed of a metal that is absorbable by a mammalian body. A polymer is disposed on the support structure in at least partially overlying relationship. The polymer has a thickness and a rate of absorption by a mammalian body such that said polymer is substantially completely absorbed, exposing the underlying portion of the support structure, before the underlying portion of the support structure is absorbed. In another embodiment, the medical device includes a support structure formed of a first material, the first material being absorbable by a mammalian body. An absorption inhibitor disposed on the support structure in at least partially overlying relationship and formed of a second material different from the first material. The second material being absorbable by the mammalian body The absorption inhibitor reducing a rate of absorption of the portion of the support structure. | 05-20-2010 |
| 20100161037 | MEDICAL DEVICES COATED WITH POROUS CARBON AND METHODS OF MANUFACTURING THE SAME - A method of creating a porous carbon coating on a medical device by applying a precursor carbon material on the medical device and then pyrolysing the precursor carbon material by laser irradiation. The laser irradiation may be focused to carbonize only certain portions of the medical device and any uncarbonized areas can be removed by solvent washing. Also provided is a medical device having a carbonized coating created according to the method of the present invention. | 06-24-2010 |
| 20110022160 | Medical Devices Having an Inorganic Coating Layer Formed by Atomic Layer Deposition - Medical devices having a coating that comprises one or more inorganic coating layers. The inorganic coating layer may be formed by a self-limiting deposition process, such as atomic layer deposition. The inorganic coating layer may have a thickness of less than 30 nm. The inorganic coating layer may also be used in combination with a therapeutic agent as a control release barrier. The inorganic coating layer may have various desirable properties, including, for example, resistance to cracking or delamination, high degree of uniformity, high degree of conformality, and/or compatibility with low deposition temperatures. | 01-27-2011 |
| 20110137155 | DELIVERY DEVICE FOR LOCALIZED DELIVERY OF A THERAPEUTIC AGENT - Therapeutic agent delivery devices and methods for delivering a therapeutic agent to a target location as well as methods for determining the location of a lesion on a vessel wall are disclosed. Various embodiments disclose an expandable member comprising a drug delivery matrix for selectively delivering a therapeutic agent to a lesion on a vessel wall. The drug delivery matrix may comprise one or more sensors and an electroactive polymer for releasing the therapeutic agent.
