20090118815 | STENT - Endoprosthesis includes coatings of selected porosity formed of particulates of ceramics, metals, drugs and/or polymers. | 05-07-2009 |
20090259300 | Medical Devices With an Interlocking Coating and Methods of Making the Same - Disclosed herein are medical devices, such as intravascular stents, for delivering a therapeutic agent to the body tissue of a patient, and a method for making such medical devices. More particularly, the medical devices have a coating that includes a polymer that adheres to the surface of the medical device so that the coating is able to resist damage during loading, deployment and implantation. | 10-15-2009 |
20090281613 | Endoprostheses - An endoprosthesis includes a body defining a flow passage therethrough. The body is capable of maintaining patency in a blood vessel and includes iron or an alloy thereof. The body has a nano-structured surface comprising iron oxide in which the individual nano-structures have a height to thickness aspect ratio of at least 5:1. | 11-12-2009 |
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 |
20100030140 | LOCATING SIDE CATHETER BRANCH RELATIVE TO INFLATION PORTION - A side catheter branch of a catheter assembly is oriented with respect to the main or side balloons of a catheter assembly. In some examples, the orientation is accomplished by connecting the side catheter branch to the main and/or side balloons or waste portions thereof. In other examples, the side catheter branch is positioned within the folds of the main or side balloons during assembly of the catheter assembly. In this manner, the side catheter branch remains in a known orientation with respect to the main and/or side balloons prior to and/or after deployment. | 02-04-2010 |
20100152711 | OFFSET COUPLING REGION - The invention provides a medical device delivery system comprising an offset coupling region interposed between an elongated hypotube guide member or catheter and a support segment. The medical device to be delivered is disposed about the support segment and contained and/or constrained within a containment element. The medical device may be released from the containment element by moving an actuation element from a first position to a second position. The offset coupling region allows the actuation element to exit a lumen within the guide member and to engage the containment element in the first position while traveling along a line generally coaxial with the lumen of the guide member. | 06-17-2010 |
20110054514 | EMBOLIC PROTECTION DEVICES WITH AN IMPROVED FILTER MEMBRANE - Embolic protection filtering devices and methods for making and using the same. An example embolic protection filter device may include an elongate shaft. A filter may be coupled to the shaft. The filter may include a filter frame and a filter membrane having a plurality of apertures formed therein attached to the filter frame. The filter may be configured to shift between a first collapsed configuration and a second expanded configuration. The apertures may have a first shape when the filter is in the first configuration and a second shape when the filter is in the second configuration. | 03-03-2011 |
