摘要： A replacement prosthetic heart valve for engagement with a structure of a previously implanted prosthetic heart valve. The replacement heart valve includes a stent structure including a generally tubular body portion with an interior area and a series of wire portions arranged in a mesh-like configuration, and at least one stent post engaging structure extending radially outwardly from the body portion for engaging with an outer surface of a stent post of the previously implanted prosthetic heart valve. The stent structure further includes at least two leaflets attached within the interior area of the tubular body portion of the stent structure.

摘要： A method of percutaneously delivering a multi-layered stent assembly to a desired implantation location of a patient including the steps of radially compressing a multi-layered stent assembly to a compressed size for implantation in a patient, the multi-layered stent assembly including a first stent, a second stent coaxially positioned within at least a portion of a length of the first stent, and a valve, wherein the first stent comprises at least one different material property than the second stent. The method further includes delivering the multi-layered stent assembly to the desired implantation location of the patient using a delivery system and substantially simultaneously expanding the first stent and the second stent of the multi-layered stent assembly at the desired implantation location to a radially expanded size that is larger than the compressed size.

摘要： A heart valve that can be expanded following its implantation in a patient, such as to accommodate the growth of a patient and the corresponding growth of the area where the valve is implanted, and to minimize paravalvular leakage. In one aspect, the invention may maximize the orifice size of the surgical valve. The invention includes expandable implantable conduits and expandable bioprosthetic stented valves. In one aspect of the invention, the valve may be adapted to accommodate growth of a patient to address limitation on bioprosthetic valve lifespans.

摘要： A flexible annuloplasty prosthesis for repairing a heart valve having a valve annulus. The annuloplasty prosthesis comprises a flexible body defining an exterior of the prosthesis formed of a biocompatible material and configured to rest against and support the heart valve annulus upon implantation. The flexible annuloplasty prosthesis has a height of not more than 2.5 mm. This low profile characteristic enhances a surgeon's ability to implant the prosthesis. In one preferred embodiment, the flexible body is a fabric material folded onto itself along a length thereof, with the annuloplasty prosthesis being characterized by an elevated longitudinal stiffness.

摘要： An annuloplasty band comprising a sheath, and a generally arcuate stiffening element disposed within the sheath. The stiffening element extends from a first end to a second end, and preferably includes eyelets at its first and second ends adapted to receive sutures to secure the annuloplasty band to a valve annulus. The annuloplasty band preferably has a low profile (e.g., a thickness less than 3 mm). In embodiments intended for mitral valve repair, the eyelets are particularly adapted to receive sutures to secure the annuloplasty band to the antero-lateral trigone and postero-medial trigone. A holder and sizer device useful with the annuloplasty band are also provided.
