20110257729 | Implantable Prosthetic Valve - A valve prosthesis device is disclosed suitable for implantation in body ducts. The device comprises a support stent, comprised of a deployable construction adapted to be initially crimped in a narrow configuration suitable for catheterization through the body duct to a target location and adapted to be deployed by exerting substantially radial forces from within by means of a deployment device to a deployed state in the target location, 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. The support stent is provided with a plurality of longitudinally rigid support beams of fixed length. When flow is allowed to pass through the valve prosthesis device from the inlet to the outlet, the valve assembly is kept in an open position, whereas a reverse flow is prevented as the collapsible slack portions of the valve assembly collapse inwardly providing blockage to the reverse flow. | 10-20-2011 |

20120277856 | IMPLANTABLE PROSTHETIC VALVE - A method of replacing a deficient native aortic valve with a self-expandable prosthetic valve is disclosed. The method involves advancing a self-expandable prosthetic valve through a tapered tube for crimping the prosthetic valve into a crimped diameter. The prosthetic valve is then advanced into a restriction tube for maintaining the prosthetic valve in the crimped diameter. The prosthetic valve is then advanced into a body and is positioned within the deficient native aortic valve. The prosthetic valve is then released from the restriction tube such that the prosthetic valve self-expands to an expanded diameter for anchoring within the deficient native aortic valve. The prosthetic valve comprises an expandable tubular support frame and a valve assembly positioned within the support frame. The valve assembly is formed with pericardial tissue and has three leaflets for providing blockage to a reverse flow of blood. | 11-01-2012 |
20130268069 | DEVICE AND METHOD FOR REDUCING MITRAL VALVE REGURGITATION - In one embodiment, the present invention provides a prosthesis that can be implanted within a heart to at least partially block gaps that may be present between the two mitral valve leaflets. In one preferred embodiment, the prosthesis includes an anchoring ring that expands within the left atrium to anchor the prosthesis and a pocket member fixed to the anchoring ring. When the mitral valve is open, blood flows past the pocket member, maintaining the pocket member in a collapsed state. When the mitral valve closes, the backpressure of the blood pushes into the pocket member, expanding the pocket member to an inflated shape. The mitral valve leaflets contact the expanded pocket member, allowing the prosthesis to block at least a portion of the openings between the leaflets, thereby minimizing regurgitated blood flow into the left atrium. | 10-10-2013 |

Some embodiments or the support frame comprise a proximal portion and a distal portion, a diameter of the proximal portion smaller than a diameter of the distal portion. The proximal portion is dimensioned for deployment in an annulus of a native aortic valve and a distal portion for deployment in an ascending aorta. Some embodiments of the conduit comprise a support construction with a three-cusp, crown-shaped cut line, the support construction sutured to the support frame around a bottom portion thereof and around the cut line. A method for using the prosthetic heart valve to replace a defective native aortic valve uses a minimally invasive procedure. | 05-15-2014 |
