Method for manufacturing personalized naturally designed mitral prosthesis
A method for manufacturing a personalized naturally designed mitral valve prosthesis to precisely fit a specific patient for which the valve prosthesis is made for is provided. The method includes measuring size and shape of a mitral valve of the specific patient by using imaging methods, calculating geometry and dimensions of annular ring, leaflets and chords per the specific patient based on validated algorithms, and cutting and connecting the annular ring, leaflets and chords to form a personalized prosthesis mitral valve.
VALVE PROSTHESIS FIXATION TECHNIQUES USING SANDWICHING
A prosthetic apparatus for implantation at a native valve complex includes a main body configured for placement within the native valve, at least one downstream arm and at least one upstream arm, each coupled to and disposed outside of the main body. The main body includes a compressed state for delivery and an expanded state. In the expanded state, a space exists between the downstream arm and an outer surface of the main body to receive an edge of a native valve leaflet. A portion of the downstream arm is configured to extend behind the received native leaflet and engage a downstream surface of the native valve complex while the edge of the received native leaflet is not engaged by the downstream arm. The upstream arm is configured to engage an upstream surface of the native valve complex at a location opposite the portion of the downstream arm.
Intracardiac-Echocardiography-based Mitral and Trisucpid Replacement Valve
A method of constructing a replacement valve for repairing a heart having an annulus separating upstream and downstream regions. The method includes obtaining a representative perimetrical length of the annulus and fabricating a frame having a hub and legs extending outward from the hub to anchors axially offset from the hub. The method includes fabricating an annular band having a circumferential length corresponding to the representative length and attaching the band to the legs. The method includes forming a flexible component having a convex face having a margin and an axially offset region. And a concave face and connecting the offset region to the hub and portions of the margin to the band and/or a portion of the frame. The valve component moves to an open position when upstream pressure is greater than downstream pressure and to a closed position when downstream pressure is greater than upstream pressure.
MITRAL PROLAPSE VALVE RESTRICTOR
The present disclosure provides unique medical devices for treating prolapsing valves, as well as associated methods of forming and using those devices. The present disclosure provides cardiac valve implants configured to attach to or brace against patient tissue within the atrium.
Heart Valve Implant And Methods For Delivering And Implanting Same
Heart valve implants and methods for implanting and delivering same are described. A heart valve implant can include a shaft, having a first end and a second end, an anchor, and a plurality of wafers. The anchor is coupled to the first end of the shaft and configured to secure the heart implant to a patient's heart. The wafers are coupled to the second end of the shaft and configured to form a stacked array of wafers. The stacked array of wafers can partially reduce a flow of blood through a heart valve upon coming in contact with a portion of a leaflet of the heart valve.
REPLACEMENT HEART VALVE WITH IMPROVED STITCHING
A replacement heart valve implant may include an expandable anchor member, a plurality of valve leaflets disposed within the anchor member, a seal member disposed about a distal portion of the anchor member, one or more whip sutures attaching a distal end of the seal member to a distal end of the plurality of valve leaflets at a joint, one or more distal lashing sutures attaching a distal portion of the seal member to a distal end of the anchor member, and a plurality of proximal lashing sutures attaching a proximal portion of the seal member to the distal portion of the anchor member, wherein the one or more distal lashing sutures does not extend through the seal member.
Mitral valve prosthesis implantation
A heart valve prosthesis and methods of its implantation are described herein. The prosthesis can be implanted in a heart of a patient by positioning an upper support of an anchoring element into a left atrium of the patient. The upper support can expand adjacent to a native valve structure of the patient. Further, the upper support can be moved against the native valve structure in a direction toward a left ventricle of the patient. A lower support of the anchoring element can be positioned into the left ventricle, spaced apart from the upper support, the lower support being separate from the upper support and coupled to the upper support by a flexible connector. Finally, the lower support can expand within the left ventricle, and engagement members of the lower support can engage with tissue of the native valve structure.
Transcatheter stent-valves and methods, systems and devices for addressing para-valve leakage
Some embodiments of the present disclosure provide a stent-valve for transcatheter implantation to replace a cardiac valve. In some embodiments, the stent valve being compressible to a compressed state for delivery, and expandable to an operative state for implantation. In some embodiments, the stent-valve comprises a stent, a plurality of leaflets for defining a prosthetic valve, an inner skirt, an outer skirt, and a paravalve seal for sealing against surrounding tissue. In some embodiments, the paravalve seal comprising material that swells in response to contact with blood or components thereof.
ARTIFICIAL HEART VALVE
To provide an artificial heart valve capable of aiding the functions of the mitral valve of a patient in a minimally invasive manner. An artificial heart valve 1 which includes a valve leaflet securing part 2 and valve leaflets (a first valve leaflet 5 and a second valve leaflet 7), and in which the valve leaflets are connected to the valve leaflet securing part 2 at the top portion of the artificial heart valve 1, the valve leaflets each have a region which narrows in width toward the bottom of the leaflet, and the artificial heart valve is an artificial mitral valve or an artificial tricuspid valve.
Stented valve
A stented valve suitable for use in body ducts. The valve includes an expandable support structure and an attached flexible membrane that changes shape when the valve opens and closes. The expandable support structure has the shape of a stent with a series of interconnected expandable unit cells and elongated support beams. When the valve is open, body fluid can flow around the membrane and pass through the gap between it and the inner stent surface. In one configuration, a set of two valves is combined with an intermediate inflatable balloon to create a cardiac assist pumping device. In another embodiment, valve closure can be achieved by remotely controlled valve leaflets actuation. A double aorta valve frame is used to accommodate shape and diameter variations of the annulus in an outer valve frame, while the inner valve frame has dimensions for optimized performance of the valve membrane.
