20120191182 | PROSTHETIC INSERT FOR TREATING A MITRAL VALVE - A prosthetic insert member for improving the function of a mitral valve is disclosed. The insert member is configured for insertion between leaflets of mitral valve. The insert member has an elongated cross-sectional profile for conforming to the opening in the mitral valve. The device also includes an anchoring member for attachment to heart tissue for maintaining the insert member in the mitral valve. In operation, the insert member fills the opening between the leaflets of the mitral valve and reduces regurgitation while preferably allowing the leaflets to function in a substantially normal manner. In one embodiment, the insert member is formed with a valve member disposed in a passageway for allowing blood to pass through the insert member in one direction. | 07-26-2012 |
20120239142 | PROSTHETIC HEART VALVE DELIVERY APPARATUS - Certain embodiments of the present disclosure provide a prosthetic valve (e.g., prosthetic heart valve) and a valve delivery apparatus for delivery of the prosthetic valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic heart valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. The delivery apparatus in particular embodiments is configured to deploy a prosthetic valve from a delivery sheath in a precise and controlled manner at the target location within the body. | 09-20-2012 |
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 |
20140163670 | PROSTHETIC HEART VALVE DELIVERY SYSTEM AND METHOD - A method for delivering a self-expanding prosthetic heart valve comprises positioning the prosthetic heart valve in an annulus of a native heart valve while mounted in a radially compressed state in a delivery cylinder, the delivery cylinder coupled to a distal end portion of the torque shaft, and rotating a torque shaft coupled to the delivery cylinder. Rotating the torque shaft retracts the delivery cylinder, thereby exposing the prosthetic heart valve, allowing the prosthetic heart valve to self-expand in the native valve annulus. In some embodiments, the torque shaft is rotated by a motor disposed in a handle at a proximal end of the delivery device. | 06-12-2014 |
20140309730 | Heart Valve Repair Device - A heart valve annulus repair device having a tissue engaging member and a plurality of anchors. The tissue engaging member includes a loop of wire. Each of the anchors has a pointy front end and a back end and a slot that runs in a front-to-back direction. The anchors are distributed about the loop of wire with the front ends of the plurality of anchors facing the heart valve annulus and with the loop of wire passing through the slots. The device further includes means for implanting the anchors into the heart valve annulus tissue so that the tissue engaging member becomes affixed to the heart valve annulus. | 10-16-2014 |
20150134050 | DEVICE AND METHOD FOR IMPROVING HEART VALVE FUNCTION - The invention is a method for reducing regurgitation through a mitral valve. The device and method is directed to an anchor portion for engagement with the heart wall and an expandable valve portion configured for deployment between the mitral valve leaflets. The valve portion is expandable for preventing regurgitation through the mitral valve while allowing blood to circulate through the heart. The expandable valve portion may include apertures for reducing the stagnation of blood. In a preferred configuration, the device is preferably configured to be delivered in two-stages wherein an anchor portion is first delivered and the valve structure is then coupled to the anchor portion. In yet another embodiment, the present invention provides a method of forming an anchor portion wherein a disposable jig is used to mold the anchor portion into a three-dimensional shape for conforming to a heart chamber. | 05-14-2015 |
20150173900 | PROSTHETIC INSERT FOR TREATING A MITRAL VALVE - A method of using a device to improve the function of a heart valve is disclosed. In one preferred embodiment, the method includes positioning a prosthetic insert member between leaflets of mitral valve. The insert member has an elongated cross-sectional profile for conforming to gap between leaflets of a mitral valve. The device also includes an anchoring member for attachment to heart tissue for maintaining the insert member in the mitral valve. The insert member is used to plug the gap between the leaflets of the mitral valve and thereby reduce undesirable regurgitation while allowing the leaflets to function in a substantially normal manner. An anchoring member secures the prosthetic insert member to a heart wall. The anchoring member preferably includes a plurality of tissue penetrating hooks or prongs. | 06-25-2015 |
20150202043 | DEVICE AND METHOD FOR TREATMENT OF HEART VALVE REGURGITATION - A method of treating a mitral valve without open-heart surgery is disclosed. An expandable prosthesis comprises an anchoring portion and an occluding member coupled to the anchoring portion. The prosthesis is loaded into a distal end of a delivery catheter and advanced through a femoral vein and through a pre-made puncture in an atrial septum. The occluding member is then positioned in the mitral valve and the anchoring portion is positioned in the left atrium for maintaining the occluding member between the leaflets of the mitral valve. After deployment, the occluding member prevents blood from flowing from the left ventricle to the left atrium during systole. | 07-23-2015 |
