20100008970 | Drug-Eluting Endoprosthesis - A drug-eluting endoprosthesis that includes a bioerodible metal portion and a therapeutic agent. In some aspects, the endoprosthesis includes a plurality of discrete deposits and a plurality of overlying layers each overlying one of the plurality of discrete deposits. Each discrete deposit includes one or more therapeutic agents and each overlying layer includes one or more bioerodible metals. In other aspects, the bioerodible metal portion includes at least two bioerodible metal regions having different electronegativities. The at least two bioerodible metal regions being in electrical contact with each other. The bioerodible metal erodes in a physiological environment to release the therapeutic agent. | 01-14-2010 |
20100222873 | Self-Buffering Medical Implants - A medical implant includes a bioerodible portion that includes a bioerodible polymer and a bioerodible metal. The bioerodible polymer matrix degrades under physiological conditions to form acidic degradation products. The bioerodible metal degrades under physiological conditions to form basic degradation products. The acidic degradation products and the basic degradation products buffer at least a portion of the medical implant. In one aspect, the bioerodible portion includes a bioerodible polymer matrix and a bioerodible metal within the bioerodible polymer matrix. In another aspect, the medical implant can include a body, a plurality of discrete deposits of the bioerodible polymer on the body, and a plurality of discrete deposits of the bioerodible metal on the body. | 09-02-2010 |

20120059455 | Bioerodible Magnesium Alloy Containing Endoprostheses - A bioerodible endoprosthesis includes a bioerodible magnesium alloy. The bioerodible magnesium alloy includes magnesium, between 7 and 8 weight percent aluminum, between 0.4 and 0.8 weight percent zinc, and between 0.05 and 0.8 weight percent manganese. | 03-08-2012 |
20120177910 | Coated Medical Devices - The present invention relates to medical devices, and in particular, medical devices that have an inorganic coating, e.g., a coating capable of releasing inorganic nanoparticles into a passageway to be treated with the medical device. | 07-12-2012 |
20120239138 | IMPLANTABLE MEDICAL DEVICES INCORPORATING X-RAY MIRRORS - An implantable medical device includes a radiolucent member provided with an x-ray mirror that reflects incident x-ray radiation to enable visualization of the device. The x-ray mirror includes a multilayer nanolaminate having alternating layers of a first metal or ceramic layer deposited by atomic layer deposition having a first refractive index, and a second metal or ceramic layer deposited by atomic layer deposition having a second refractive index that is different from the first refractive index. The nanolaminate includes a total of at least four layers. | 09-20-2012 |
20120316633 | Durable Stent Drug Eluting Coating - In embodiments, medical devices, such stents, can deliver a therapeutic agent to body tissue of a patient. The medical device includes a porous therapeutic layer that is substantially free of a polymer matrix which can withstand expansion or contraction of the medical device, with minimal delamination. | 12-13-2012 |
20130123714 | VESSEL PROTECTION MEMBRANE - A medical device assembly may include an elongated guidewire, an elongated flexible tubular membrane disposed about the guidewire, and a percutaneous medical device, wherein the membrane is configured to permit the percutaneous medical device to pass through the lumen. A method of advancing a medical device through a vessel may include advancing an elongated flexible tubular membrane through the vessel to a treatment site, inserting the medical device into the membrane, and advancing the medical device through the membrane while maintaining the membrane in an axially stationary position relative to the vessel. | 05-16-2013 |
20130226287 | VALVULOPLASTY DEVICE - The disclosure pertains to valvuloplasty devices which include a first outer shaft, a second inner shaft, a plurality of elongate members disposed therebetween and adapted to be expanded radially by relative motion between the first outer shaft and second inner shaft and a circumferential member disposed about the central portions of the plurality of elongate members, wherein the circumferential member is urged by radial expansion of the plurality of elongate members to contact the valve to be treated thereby effecting a valvuloplasty and methods of use therefor. | 08-29-2013 |
