20080262507 | INSTRUMENT AND METHOD FOR IN SITU DEPLOYMENT OF CARDIAC VALVE PROSTHESES - An instrument for deploying a cardiac valve prosthesis, including a plurality of radially expandable portions, at an implantation site, includes a plurality of deployment elements each independently operable to obtain the radial expansion of a radially expandable portion of the valve prosthesis. A method for deploying the cardiac valve prosthesis includes advancing the instrument to an implant site and independently actuating the radially expandable portions. | 10-23-2008 |
20110288636 | SUPPORT DEVICE FOR VALVE PROSTHESES AND CORRESPONDING KIT - A support device for implanting stentless valve prostheses, such as biological heart valves, includes a hub and a plurality of support portions for supporting the stentless valve prosthesis. The hub defines a manipulation axis for the device and is flexibly connected to the support portions to allow displacing the manipulation axis for the device between the support portions. | 11-24-2011 |
20130172991 | PROSTHETIC VASCULAR CONDUIT AND ASSEMBLY METHOD - A kit for implanting a prosthetic vascular conduit includes a prosthetic vascular conduit for coupling to a prosthetic valve having an annular portion. The conduit includes a terminal collar member for receiving the valve. The kit further includes a holder including a shaft and a hub including a receiving portion configured for housing a prosthetic valve. The conduit is fitted on the holder so that at least a portion of the conduit wraps over the receiving portion of the hub. A sleeve member fitted onto the conduit in a position corresponding to the receiving portion of the hub, and a portion of the collar member is wrapped or folded over the sleeve member. The sleeve member is slidable away from the hub to unwrap the collar member such that it is disposed around the annular portion of a prosthetic valve. | 07-04-2013 |
20130253643 | COLLAPSIBLE VALVE PROSTHESIS - A collapsible valve prosthesis includes an armature and a set of prosthetic valve leaflets supported by the armature. The armature is expandable from a contracted condition to an expanded condition for anchoring at an annulus of a natural valve site, and includes a tubular intra-annular portion defining a blood flow lumen having an inflow side and an outflow side. The tubular intra-annular portion supports the prosthetic valve leaflets in the blood flow lumen and is provided with outward formations for coupling with the natural valve site. The armature includes an over-annular portion linked to the intra-annular portion to extend collar-like over the annulus of the natural valve site at the inflow side of the blood flow lumen. The armature may also include an under-annular portion to extend collar-like at the outflow side of the blood flow lumen. The prosthesis may permit mitral valve replacement (MVR) without removing the native valve leaflets and the chordae tendineae. | 09-26-2013 |
20140046434 | VALVE PROSTHESIS AND KIT - Described is a valve prosthesis comprising: an annular structure, and a plurality of valve leaflets, and a plurality of anchoring members attached around the annular structure, the anchoring members including: a web portion coupled to the annular structure and extending axially thereto, and two end portions at axially opposed sides of the web portion, the end portions having: an insertion condition for insertion of the prosthesis, wherein the end portions are aligned to the web portion and extend axially with respect to the annular structure; and an anchoring condition for anchoring the prosthesis, wherein the end portions extend at an angle to the web portion radially outwardly of the annular structure to provide anchoring of the prosthesis proximally and distally, respectively, of the annulus, and wherein one end portion forms an obtuse angle with the web portion. | 02-13-2014 |
20140188217 | PROSTHETIC VASCULAR CONDUIT AND ASSEMBLY METHOD - A kit for implanting a prosthetic vascular conduit includes a prosthetic vascular conduit for coupling to a prosthetic valve having an annular portion. The conduit includes a terminal collar member for receiving the valve. The kit further includes a holder including a shaft and a hub including a receiving portion configured for housing a prosthetic valve. The conduit is fitted on the holder so that at least a portion of the conduit wraps over the receiving portion of the hub. A sleeve member fitted onto the conduit in a position corresponding to the receiving portion of the hub, and a portion of the collar member is wrapped or folded over the sleeve member. The sleeve member is slidable away from the hub to unwrap the collar member such that it is disposed around the annular portion of a prosthetic valve. | 07-03-2014 |
20150051698 | APPARATUS AND METHOD FOR CHORDAL REPLACEMENT - Described is a prosthetic device and methods for repairing a mitral valve having an annulus, leaflets, and chordae tendinae. The device comprises an elongate band including a plurality of reference elements that are located along the elongate band and protrude inwardly with respect thereto towards a center of the annulus, the plurality of reference elements being adapted to receive a corresponding plurality of artificial cords that are tied onto the reference elements and the plurality of reference elements adapted to be cut or removed in order to release the tied artificial cords. | 02-19-2015 |
20150374495 | APPARATUS AND METHOD FOR CHORDAL REPLACEMENT - Described is a prosthetic device and methods for repairing a mitral valve having an annulus, leaflets, and chordae tendinae. The device comprises an elongate band including a plurality of reference elements that are located along the elongate band and protrude inwardly with respect thereto towards a center of the annulus, the plurality of reference elements being adapted to receive a corresponding plurality of artificial cords that are tied onto the reference elements and the plurality of reference elements adapted to be cut or removed in order to release the tied artificial cords. | 12-31-2015 |
