20090118812 | ENDOPROSTHESIS COATING - A method includes: providing a substrate, depositing a ceramic and an extractable material onto the substrate, forming a porous structure in the ceramic by removing the extractable material, and utilizing the ceramic in an endoprosthesis. An endoprosthesis, such as a stent, including a coating formed of a ceramic and an extractable material that can be removed from the coating to form voids is also disclosed. | 05-07-2009 |
20090149942 | ENDOPROSTHESIS HAVING A NON-FOULING SURFACE - An endoprosthesis, e.g., a stent, that includes a pro-healing surface and a temporary non-fouling material attached to the surface, and a method of making the same are disclosed. | 06-11-2009 |
20100023115 | DRUG-ELUTING STENT - A stent for delivering therapeutic agents to a body lumen includes a plurality of circumferential serpentine bands with each band comprising a plurality of struts. At least one strut has at least one first well region and at least one second well region. The at least one first well region has a first thickness, the at least one second well region has a second thickness, the first thickness being greater than the second thickness. Each well region defines a well having a depth. At least some of the wells contain a therapeutic agent. | 01-28-2010 |
20100292777 | Stent - An expandable stent has a plurality of expandable rings formed of a plurality of struts and at least one first connector interconnecting adjacent expandable rings. The plurality of struts include a first strut and the at least one first connector has a first arm. A first portion of the first arm is engaged to a first portion of the first strut so that the first portion of the first arm and the first portion of the first strut define a through hole. | 11-18-2010 |
20110066227 | Stent with Dynamic Drug Reservoirs - A stent having one or more beneficial agents which enhance the healing effect of the stent. The agent is positioned within a reservoir. The reservoir dynamically releases the agent when the stent is expanded. The reservoir makes use of various changes in stent shape during expansion to assure proper release of the agent. Agent release can be modulated at various points along the stent and with various rates of release. The reservoirs can also be cooperatively combined with features that enhance stent flexibility, structural integrity, and which prevent recoil. | 03-17-2011 |
20110270378 | Mobile External Coupling with Internal Sealing Cuff for Branch Vessel Connection - An endovascular prosthesis includes a tubular body and a mobile external coupling. The tubular body includes a graft material and stents coupled thereto, a forms a lumen therethrough. The mobile external coupling extends outwardly from the tubular body. The mobile external coupling includes a graft material and is generally frustoconically shaped. The mobile external coupling includes a base coupled to the tubular body, a top spaced from the tubular body, and a coupling lumen disposed between the base and the top, wherein the coupling lumen is in flow communication with the body lumen. A cylindrical sealing cuff of graft material is attached to and extends from the top of the mobile external coupling towards the tubular body within the coupling lumen. The sealing cuff is configured to contact a portion of a branch vessel prosthesis and thereby provides an elongated interference seal between the branch vessel prosthesis and the mobile external coupling. | 11-03-2011 |
20120271399 | High Metal to Vessel Ratio Landing Zone Stent-Graft and Method - A method includes covering an ostium of a branch vessel emanating from a main vessel with a proximal landing zone of a high metal to vessel ratio landing zone stent-graft, wherein a metal to vessel ratio of the proximal landing zone when deployed is sufficiently high to encourage tissue ingrowth around the proximal landing zone yet is sufficiently low to ensure perfusion of the branch vessel through the proximal landing zone. The method further includes covering an aneurysm of the main vessel with an exclusion zone of the high metal to vessel ratio landing zone stent-graft, the exclusion zone being formed of graft material. By forming the exclusion zone of graft material, excellent exclusion of the aneurysm is achieved. | 10-25-2012 |
20130261727 | VARIABLE ZONE HIGH METAL TO VESSEL RATIO STENT AND METHOD - A variable zone high metal to vessel ratio stent includes a proximal high metal to vessel ratio zone, a central low metal to vessel ratio zone, and a distal high metal to vessel ratio zone. The proximal high metal to vessel ratio zone is deployed with fixation and sealing to healthy tissue of a main vessel superior to branch vessels and an aneurysm. The central low metal to vessel ratio zone is deployed directly on ostai of the branch vessels. However, as the central low metal to vessel ratio zone is highly permeable, blood flows from the main vessel through the central low metal to vessel ratio zone and into branch vessels. | 10-03-2013 |
20130261728 | HIGH METAL TO VESSEL RATIO STENT AND METHOD - A method includes covering ostai of branch vessels emanating from a main vessel and an aneurysm with a high metal to vessel ratio stent. A metal to vessel ratio of the high metal to vessel ratio stent is sufficiently high to encourage tissue ingrowth around the high metal to vessel ratio stent yet is sufficiently low to ensure perfusion of the branch vessels through the high metal to vessel ratio stent. The ingrowth of tissue provides secure fixation and sealing of the high metal to vessel ratio stent to the main vessel and remodels and essentially eliminates the aneurysm. Further, as the entire high metal to vessel ratio stent is permeably, the high metal to vessel ratio stent is deployed without having to rotationally position the high metal to vessel ratio stent. | 10-03-2013 |
20130261732 | INTEGRATED MESH HIGH METAL TO VESSEL RATIO STENT AND METHOD - A method includes covering ostai of branch vessels emanating from a main vessel and an aneurysm with an integrated mesh high metal to vessel ratio stent. The integrated mesh high metal to vessel ratio stent includes serpentine rings integrated with an integrated mesh having holes formed therein. A metal to vessel ratio of the integrated mesh high metal to vessel ratio stent is sufficiently high to encourage tissue ingrowth around the integrated mesh high metal to vessel ratio stent yet is sufficiently low to ensure perfusion of the branch vessels through the integrated mesh high metal to vessel ratio stent. | 10-03-2013 |
