| 20090048669 | METHODS AND SYSTEMS FOR MODIFYING VASCULAR VALVES - Described are methods and systems for modifying vascular valves in order to reduce retrograde blood flow through the valves. Preferred methods include connecting vascular valve leaflets with at least one remodelable material, such that the valve leaflets become fused by the ingrowth of the patient's native tissue. Preferred remodelable materials include collagenous extracellular matrix material, such as small intestine submucosa. | 02-19-2009 |
| 20090069838 | INFLATABLE OCCLUSION DEVICES, METHODS, AND SYSTEMS - Described are devices, methods and systems useful for achieving occlusion of vascular vessels. Percutaneous procedures can be used to occlude and obliterate the greater saphenous vein, for example in the treatment of varicose vein condition caused by venous reflux. Certain embodiments encompass the deployment and filling of an inflatable occlusion device via a percutaneous procedure, so as to occlude or obliterate a portion of a vascular vessel. | 03-12-2009 |
| 20090099589 | INVERTING OCCLUSION DEVICES, METHODS, AND SYSTEMS - Described are devices, methods and systems useful for achieving occlusion of vascular vessels. Percutaneous procedures can be used to occlude and obliterate the greater saphenous vein, for example in the treatment of varicose vein condition caused by venous reflux. Certain embodiments encompass the percutaneous delivery of an occlusion device inverted within a cannula, its deployment and filling, so as to occlude or obliterate a portion of a vascular vessel. | 04-16-2009 |
| 20100030314 | IMPLANTABLE SUPPORT DEVICE WITH GRAFT - Implantable medical devices comprising a support frame and a graft member attached to the support frame. The support frame can define one or more structural features that substantially prevent migration of the graft member along the support frame. | 02-04-2010 |
| 20100057191 | IMPLANTABLE VASCULAR DEVICE - An valve prosthesis, such as an artificial venous valve, having a support frame and leaf structure comprising one or more leaflets in which the outer edge of each leaflet engages the inner circumference of the bodily passageway along a serpentine path urged against the passageway by an expandable frame, while the inner edges move in response to fluid to restrict retrograde flow. Optionally, one or more elements can extend from the support frame/leaf structure to provide centering support and/or protection from the leaflet adhering to the vessel wall. In one embodiment, the centering support structure comprises a second or third expandable frames attached to and extending from the proximal and/or distal ends of main valve structure and support frame. In another embodiment, one or more support elements extend outward from the valve support frame to engage the vessel wall to provide greater longitudinal stability. | 03-04-2010 |
| 20100114296 | INTRALUMENALLY-IMPLANTABLE FRAMES - Implantable frames for use in body passages are provided herein. The implantable frames can include a plurality of hoop members joined by a plurality of longitudinal connecting members to form a tubular frame defining a cylindrical lumen. The plurality of longitudinal connecting members may include first and second longitudinal connecting members joining a first hoop member to a second hoop member such that the first and second longitudinal connecting members extend across an entire space separating the first and second hoop members. | 05-06-2010 |
| 20100131055 | ARTIFICIAL VALVE PROSTHESIS WITH IMPROVED FLOW DYNAMICS - An expandable venous valve having a support structure configured to enlarge the area adjacent the valve structure. The enlarged pocket areas can be created by forming an artificial sinus adjacent the valve structure in an unsupported section of vessel wall between two support frame sections. | 05-27-2010 |
| 20100280586 | MEDICAL DEVICE WITH TENSIONABLY ATTACHED REMODELABLE MATERIAL - Medical devices for implantation in a body vessel, and methods of using and making the same, are provided. A medical device includes a support frame having struts and a weakened frame portion, and a remodelable material tensionably attached to the support frame. The weakened frame portion has a first configuration in which the support frame has a first outward radial force and a second configuration in which the support frame has a second, lesser outward radial force. The remodellable material restricts expansion of the frame from a radially compressed configuration to a radially expanded configuration when the weakened frame portion is in the first configuration. The remodelable material can form one or more valve leaflets adapted to regulate fluid flow in a body vessel, such as a vein. | 11-04-2010 |
| 20110112621 | PERCUTANEOUSLY DEPLOYED VASCULAR VALVES - Described are percutaneous vascular valves free of attached support structures and deployment systems and methods for providing attachment of the valves within a vascular vessel. | 05-12-2011 |
