20100057193 | FLEXIBLE HEART VALVE AND ASSOCIATED CONNECTING BAND - A highly flexible tissue-type heart valve is disclosed having a structural stent in a generally cylindrical configuration with cusps and commissures that are permitted to move radially. The stent commissures are constructed so that the cusps are pivotably or flexibly coupled together at the commissures to permit relative movement therebetween. The stent may be cloth-covered and may be a single element or may be made in three separate elements for a three cusp valve, each element having a cusp portion and two commissure portions; adjacent commissure portions for each pair of adjacent stent element combining to form the stent commissures. If the stent has separate elements their commissure portions may be pivotably or flexible coupled, or may be designed to completely separate into independent leaflets at bioresorbable couples. The cloth covering may have an outwardly projecting flap that mates with valve leaflets (e.g., pericardial leaflets) along the cusps and commissures. A connecting band may be provided that follows the cusps and commissures and extends outwardly. The valve is connected to the natural tissue along the undulating connecting band using conventional techniques, such as sutures. The connecting band may be a cloth-covered silicon member and attaches to the underside of the valve at the cusps to provide support to the stent and to the outer side of the valve at the commissures. The connecting band includes commissure portions defining generally axial gaps that help permit flexing of the valve. | 03-04-2010 |
20110054586 | APPARATUS AND METHOD OF PLACEMENT OF A GRAFT OR GRAFT SYSTEM - Some embodiments relate to endoluminal prostheses having a first stent portion and a second stent portion, a main graft body comprising first, second, and third portions, the second portion having a cross-sectional size that is significantly larger than a cross-sectional size of the first or third portions, and also significantly larger than a cross-sectional size of the target vessel. In some embodiments, the first portion of the main graft body can be attached to the first stent portion and the third portion of the main graft body can be attached to the second stent portion. The prostheses can be configured such that the second portion of the main graft body is not directly attached to the first stent portion, the second stent portion, or any other internal support structure. In some embodiments, one or more openings can be formed in the second portion of the main graft body. | 03-03-2011 |
20110054587 | APPARATUS AND METHOD OF PLACEMENT OF A GRAFT OR GRAFT SYSTEM - Some embodiments of the present disclosure are directed to a method of deploying a graft in a patient's blood vessel having at least a first and a second branch blood vessel, comprising advancing a delivery catheter into a blood vessel, the delivery catheter supporting a fenestrated prosthesis therein, wherein the prosthesis comprises a main graft body, exposing at least one branch sheath, the branch sheath being positioned within the delivery catheter so as to project from a main lumen of the prosthesis through a first opening formed through a wall of the prosthesis, and advancing an angiographic catheter into the branch sheath and cannulating a first target branch vessel before expanding the main graft body of the prosthesis. | 03-03-2011 |
20110054594 | FENESTRATED PROSTHESIS - Some embodiments of the present disclosure are directed to endoluminal prostheses having one or more reinforced fenestrations therein. The one or more reinforced fenestrations can have improved sealing capabilities with respect to branch grafts deployed within the fenestrations, improved tear resistance and expandability, and improved pull-out resistance for branch grafts. In some embodiments, the endoluminal prosthesis can have a main graft body defining a flow lumen therethrough, a first opening passing through a wall of the main graft body, and a first support member supported by the main graft body and overlapping an edge of the first opening, the first support member being configured to at least increase the tear resistance of the main graft body adjacent to the first opening. The support member can be stitched or otherwise attached to the main graft adjacent to the fenestration. | 03-03-2011 |
