  • Patent number: 11166810
    Abstract: An implantable prosthetic valve includes an annular metallic frame and a valve assembly supported within the frame. The annular support frame is constructed with three longitudinal support beams of fixed length and web-like constructions that extend between and connect the support beams. The support beams are spaced apart in a substantially equidistant manner. The web-like constructions allow the annular support frame to be radially collapsible and expandable. Each support beam preferably has a column of pre-formed openings or bores extending along a length of the support beam. The valve assembly includes three valve leaflets, wherein each leaflet has opposing side portions and each side portion is paired with an adjacent side portion of an adjacent leaflet to form a commissure. The three commissures are secured to three respective support beams with stitching that extends through the leaflets and through the pre-formed openings or bores.

  • Patent number: 11123182
    Abstract: A system for replacing a deficient native aortic valve includes an implantable prosthetic valve having a self-expandable frame and a valve assembly formed with three valve leaflets. The self-expandable frame includes three angularly spaced longitudinal bars of fixed length defining respective slots and a plurality of web-like constructions extending between and connected to the longitudinal bars. The valve assembly includes commissures extending outwardly through the slots where they are supported on the outside of the frame. Each leaflet includes an inlet end portion secured to the inside of the frame with stitching extending through the leaflet and around adjacent frame portions. The system also includes a restriction tube adapted for insertion into a patient's body. The prosthetic valve is capable of being crimped for insertion into the restriction tube and capable of self-expansion upon release from the restriction tube for deployment in the deficient native aortic valve.

  • Publication number: 20200315787
    Abstract: A method of treating a native mitral valve without open-heart surgery is disclosed. An expandable prosthesis includes an anchoring portion and an occluding member coupled to the anchoring portion. The prosthesis is loaded into a distal end portion of a delivery catheter and is advanced through a femoral vein and through a pre-made puncture in an atrial septum. The anchoring portion self-expands within the left atrium for anchoring the occluding member in a fixed position. The anchoring portion is preferably a laser cut structure that conforms to the left atrium and uniformly distributes anchoring forces within the left atrium. After deployment, the occluding member prevents blood from flowing from the left ventricle to the left atrium during systole. The occluding member is preferably made from a flexible material, such as pericardial tissue.

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.

  • Patent number: 10052203
    Abstract: A prosthetic heart valve comprises a radially crimpable and radially expandable, net-like, annular support frame and a valve assembly disposed therein, the valve assembly comprising a conduit tapering from an inlet towards an outlet thereof. 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.

  • Patent number: 9629717
    Abstract: A prosthetic heart valve assembly suitable for implantation in body ducts via a catheter. The prosthetic heart valve assembly includes a collapsible and expandable tubular frame having an inlet end and an outlet end. The frame is preferably made from a self-expanding material. Three pericardial leaflets form a tricuspid valve having a top portion, a middle portion, and a bottom portion. Three longitudinal support members are positioned along an internal surface of the frame, desirably proximate to the outlet end. Each support member includes a pair of longitudinal surfaces that extends radially inwardly. End portions of adjacent valve leaflets extend through a gap between the pairs of longitudinal surfaces of each support member. The end portions are sutured to the longitudinal support members. The bottom portion of the tricuspid valve is sutured to the inlet end of the frame.
