Annuloplasty ring holder
An annuloplasty ring holder including a head having an upper surface and an annuloplasty ring receiving surface facing opposite the upper surface. The annuloplasty ring holder also includes means for attaching an annuloplasty ring to the annuloplasty ring receiving surface. The means for attaching an annuloplasty ring to the annuloplasty ring receiving surface may include one or more suture guides operatively associated with the head and configured to position one or more sutures to removably associate an annuloplasty ring with the annuloplasty ring receiving surface. The head may include a central hub and more than one spoke radiating out from the central hub. If the head is thus configured, each spoke will include a portion of the annuloplasty ring receiving surface.
Prosthetic valve for transluminal delivery
A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable valve support. If desired, one or more anchor may be used. The valve support, which entirely supports the valve annulus, valve leaflets, and valve commissure points, is configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the assembly is properly positioned. The anchor engages the lumen wall when expanded and prevents substantial migration of the valve assembly when positioned in place. The prosthetic valve assembly is compressible about a catheter, and restrained from expanding by an outer sheath. The catheter may be inserted inside a lumen within the body, such as the femoral artery, and delivered to a desired location, such as the heart. When the outer sheath is retracted, the prosthetic valve assembly expands to an expanded position such that the valve and valve support expand within the deficient native valve, and the anchor engages the lumen wall.
Implantable prosthetic valve with non-laminar flow
A valve prosthesis device and methods for deployment is disclosed. The device comprises an expandable support stent and a valve assembly comprising a flexible conduit having an inlet end and an outlet, made of pliant material attached to the support beams providing collapsible slack portions of the conduit at the outlet. Flow is allowed to pass through the valve prosthesis device from the inlet to the outlet, but reverse flow is prevented as the collapsible slack portions of the valve assembly collapse inwardly. The device is configured so that retrograde flow will be altered from laminar flow and directed towards the leaflets to effect closing. The device can be deployed in a native heart valve position using a deployment catheter advanced through a body lumen such as a blood vessel, including an aorta.
CONDUIT DEVICE AND SYSTEM FOR IMPLANTING A CONDUIT DEVICE IN A TISSUE WALL
Various embodiments of the present invention provide a conduit device including an attaching device configured for defining a helical pathway through a tissue wall and complementary ring in cooperation for securing the device within an aperture defined in the tissue wall. Some embodiments of the present invention further provide a system for implanting a conduit device in a tissue wall. More specifically, some embodiments provide a system including a coring device for defining an aperture in a tissue by removing and retaining a tissue core and securely implanting a conduit device therein so as to provide fluid communication between a first and second surface of the tissue wall via the conduit device.

Prevention of myocardial infarction induced ventricular expansion and remodeling
A method for direct therapeutic treatment of myocardial tissue in a localized region of a heart having a pathological condition. The method includes identifying a target region of the myocardium and applying material directly and substantially only to at least a portion of the myocardial tissue of the target region. The material applied results in a physically modification the mechanical properties, including stiffness, of said tissue. Various devices and modes of practicing the method are disclosed for stiffening, restraining and constraining myocardial tissue for the treatment of conditions including myocardial infarction or mitral valve regurgitation.
Devices, systems, and methods for reshaping a heart valve annulus
Devices, systems, and methods employ an implant that is sized and configured to attach to the annulus of a dysfunctional heart valve annulus. In use, the implant extends across the major axis of the annulus above and/or along the valve annulus. The implant reshapes the major axis dimension and/or other surrounding anatomic structures. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets during systole, which, in turn, reduces regurgitation. The implant improves function to the valve, without surgically cinching, resecting, and/or fixing in position large portions of a dilated annulus, or without the surgical fixation of ring-like structures.
Annuloplasty Ring Holder
An annuloplasty ring holder including a head having an upper surface and an annuloplasty ring receiving surface facing opposite the upper surface. The annuloplasty ring holder also includes means for attaching an annuloplasty ring to the annuloplasty ring receiving surface. The means for attaching an annuloplasty ring to the annuloplasty ring receiving surface may include one or more suture guides operatively associated with the head and configured to position one or more sutures to removably associate an annuloplasty ring with the annuloplasty ring receiving surface. The head may include a central hub and more than one spoke radiating out from the central hub. If the head is thus configured, each spoke will include a portion of the annuloplasty ring receiving surface.
Collapsible prosthetic valve
A prosthetic valve is provided for implantation in a stenosed aortic valve. The prosthetic valve includes a radially collapsible frame configured for advancement through a patient's vasculature using a catheterization technique. A collapsible valvular structure is sewn to the frame for permitting blood to flow in only one direction. An internal cover extends along an internal surface of the frame. The internal cover forms a tubular sleeve positioned between a lower extremity of the frame and the valvular structure. The internal cover prevents the passage of blood through spaces between bars of the frame. An upper end of the internal cover is sutured to the valvular structure. The internal cover is preferably made of pericardium.
Unstented Heart Valve with Formed in Place Support Structure
An implantable prosthetic valve has an in situ formable support structure. The valve comprises a prosthetic valve, having a base and at least one flow occluder. A first flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The first component extends proximally of the base of the valve. A second flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The second component extends distally of the base of the valve. At least one rigidity component combines with at least one of the first and second flexible components to impart sufficient rigidity to the first or second components to retain the valve at the site.
