20120172981 | PROSTHETIC VALVES FORMED WITH SUPPORTING STRUCTURE AND ISOTROPIC FILTER SCREEN LEAFLETS - In one embodiment of the invention, a prosthetic check valve is disclosed with leaflets cut from filtration screen material with uniform pore size having openings with a dimension inclusively between fifteen and sixty microns. The screen material is made from biocompatible material, such as polyester or polypropylene. One or more outer edges of the leaflet are fused or sealed to prevent fraying of the material and to form a more non-thrombogenic surface. The prosthetic check valve includes a supporting structure to which the leaflets may couple. Prosthetic check valves assembled with the leaflets can be collapsed to a diameter of less than or equal to twenty-nine french (29 f), sterilized, and stored in a collapsed state. The collapsed valve can be implanted without prior rinsing to remove sterilant. | 07-05-2012 |
20120172980 | KITS WITH PROSTHETIC VALVES FORMED WITH ISOTROPIC FILTER SCREEN LEAFLETS AND METHODS THEREOF - In one embodiment of the invention, a catheter delivery system or kit is disclosed. The kit contains a prosthetic check valve with leaflets cut from filtration screen material with uniform pore size having openings with a dimension inclusively between fifteen and sixty microns. The screen material is made from biocompatible material, such as polyester or polypropylene. One or more outer edges of the leaflet are fused or sealed to prevent fraying of the material and to form a more non-thrombogenic surface. Prosthetic check valves assembled with the leaflets can be collapsed to a diameter of less than or equal to twenty-nine french (29 f), sterilized, and stored in a collapsed state. The compressed or collapsed valve may be sterilized and included as part of a sterile catheter delivery system or kit, ready for minimally invasive implantation without rinsing prior to use. | 07-05-2012 |
20120172979 | METHODS FOR PROSTHETIC VALVES FORMED WITH ISOTROPIC FILTER SCREEN LEAFLETS - In one embodiment of the invention, a method of forming a prosthetic check valve is disclosed. The prosthetic check valve is formed of leaflets cut from filtration screen material with uniform pore size having openings with a dimension inclusively between fifteen and sixty microns. The screen material is made from biocompatible material, such as polyester or polypropylene. One or more outer edges of the leaflet are fused or sealed to prevent fraying of the material and to form a more non-thrombogenic surface. Prosthetic check valves assembled with the leaflets can be collapsed to a diameter of less than or equal to twenty-nine french (29 f), sterilized, and stored in a collapsed state.
