The dried biocompatible tissue material is folded and rehydrated in such a way that forms a two- or three-leaflet/cusp valve without affixing of separate cusps or leaflets or cutting slits into the biocompatible tissue material to form the cusps or leaflets. After the biocompatible tissue material is folded, it is affixed at one or more points on the outer surface to the inner cavity or a stent. | 2014-09-11 |
20140257470 | METHOD AND APPARATUS FOR RESECTING AND REPLACING AN AORTIC VALVE - Apparatus for resecting a diseased heart valve, the apparatus comprising: a body portion; a first handle and a second handle; a cutting blade; a set of retaining arms; a pass-off tool having a first attachment device configured to selectively engage the first handle attached to the body portion so as to allow placement of the second handle of the body portion adjacent to the diseased heart valve, and a controller tool having a second attachment device at the distal end thereof, the second attachment device configured to selectively engage the second handle attached to the body portion so as to allow positioning of the body portion adjacent to the diseased heart valve, a cutting blade actuator configured to cause the cutting blade to selectively rotate, and a retaining arm actuator configured to selectively position the set of retaining arms from the contracted state to the expanded state. | 2014-09-11 |
20140257471 | Controlled Tip Release Stent Graft Delivery System and Method - An apparatus and method of deploying a stent graft having a proximal anchor stent ring includes restraining proximal apexes of the proximal anchor stent ring between a spindle body of a spindle and a control release sleeve of a tapered tip. The control release sleeve is advanced relative to the spindle to release a first proximal apex through an opening in the control release sleeve while the remaining proximal apexes remain restrained by the control release sleeve. The control release sleeve is further advanced relative to the spindle to release the remaining proximal apexes from the control release sleeve. In another example, a stent capture fitting has variable length stent capture fitting arms. As the stent capture fitting is retracted, the proximal apexes of the proximal anchor stent ring are sequentially exposed from and released by the variable length stent capture fitting arms. By using the control release sleeve or the stent capture fitting, controlled sequential release of the proximal apexes is achieved. | 2014-09-11 |
20140257472 | METHOD OF PREPARING A TISSUE SWATCH FOR A BIOPROSTHETIC DEVICE - A method of preparing a tissue swatch comprising one or more desired thicknesses for use in the manufacture of a bioprosthetic device, said method comprising sectioning a sheet of frozen tissue to produce a tissue swatch of said one or more desired thicknesses. | 2014-09-11 |
20140257473 | METHODS FOR INHIBITING STENOSIS, OBSTRUCTION, OR CALCIFICATION OF A STENTED HEART VALVE OR BIOPROSTHESIS - The present invention relates to methods for inhibiting stenosis, obstruction, or calcification of a valve following implantation of a valve prosthesis which may involve disposing a coating composition on an elastical stent or valve leaflet. The valve prosthesis is mounted on the elastical stent such that the elastical stent is in contact with the valve. | 2014-09-11 |
