| 20130131793 | REPLACEMENT HEART VALVE AND METHOD - A heart valve includes a valve body made of a flexible material such as pericardium. The valve body is made of two layers of material, an outer layer, and an inner layer that defines a plurality of leaflets. The leaflets of the inner layer are attached to the outer layer. In some embodiments the valve body is made by cutting a single piece of flat source tissue, folding the cut tissue and forming it into a tubular pattern having the inner and outer layers. The multi-layer valve body can be mounted on a stent for delivery within a patient's heart. | 05-23-2013 |
| 20130131788 | BODY CAVITY PROSTHESIS - A prosthesis can be configured to be deployed within a body cavity. The prosthesis has an expandable frame, a plurality of proximal anchors, and a plurality of distal anchors, where the various anchors are connected to the frame. Radial expansion of the frame can cause the ends of the proximal anchors and the ends of the distal anchors to draw closer together. | 05-23-2013 |
| 20120215303 | REPLACEMENT HEART VALVE AND METHOD - A replacement heart valve has an expandable frame configured to engage a native valve annulus and a valve body mounted to the expandable frame. The valve body can have a plurality of valve leaflets configured to open to allow flow in a first direction and engage one another so as to close and prevent flow in a second direction, the second direction being opposite the first direction. | 08-23-2012 |
| 20120179239 | VASCULAR PROSTHESIS CONNECTING STENT - An expandable vascular stent includes an m 3 n array of ovals formed in a cylinder, m being the number of columns of ovals in the circumferential direction and n being the number of rows of ovals in the axial direction, and a plurality of prongs extending inwardly from the outer ends of respective ovals in rows 1 and n of the m 3 n array, and being arranged in facing pairs extending from axially-aligned ovals. The cylinder is expandable from an initial diameter to a pre-determined final diameter, wherein an increase in the diameter of the stent results in a substantial decrease in the length of the stent. The tube and the prongs can be made of surgical stainless steel, the tube being expandable using an angioplasty balloon; or the tube and the prongs can be made of a memory metal and the tube is self-expanding. | 07-12-2012 |
| 20120078353 | REPLACEMENT HEART VALVES, DELIVERY DEVICES AND METHODS - A replacement heart valve and method of treating valve insufficiency includes an expandable frame configured to engage a native valve annulus. A valve body is coupled to the frame. The valve body can include a leaflet portion and possibly a skirt portion. A portion of the frame has a foreshortening portion configured to longitudinally expand when urged to a radially compacted state and longitudinally contract when urged to a radially expanded state. In one embodiment the valve skirt is attached to the frame so that it can adapt to changes in the length of the frame. A delivery device in some embodiments can use one or more coverings, such as sheaths, to controllably release the replacement heart valve at a native heart valve. | 03-29-2012 |
| 20090012602 | System and method for endoluminal grafting of bifurcated and branched vessels - A system and method for endoluminal grafting of a main anatomic conduit in its diseased state in which it dilates to pose a life threatening condition and its various conduits that emanate from the main anatomic conduit. The grafting system comprises an endoaortic graft having at least one opening therein and at least one branch graft that is passable through the opening of the endoaortic graft into the branch anatomic conduit(s) such that the junction between the branch graft and the endoaortic graft is substantially fluid tight. A system and method for delivery of the endoaortic graft and also a system and method for efficient alignment and deployment of the branch (e.g., side branch) graft such that the coupling of the branch graft with the endoaortic graft is efficient and exact and fluid-tight; and a system and method for coupling the branch to the endoaortic graft via a coupling mechanism employing a memory metal alloy; a system and method for the proper and exact alignment of the endoaortic graft and the branch using magnetic force of a suitable nature, and which does not use the magnetic force as the coupling mechanism. | 01-08-2009 |
