  • Collapsible-Expandable Prosthetic Heart Valves With Structures for Clamping Native Tissue
    Publication number: 20200015963
    Abstract: A prosthetic heart valve is designed to be circumferentially collapsible for less invasive delivery into the patient. At the implant site the valve re-expands to a larger circumferential size, i.e., the size that it has for operation as a replacement for one of the patient's native heart valves. The valve includes structures that, at the implant site, extend radially outwardly to engage tissue structures above and below the native heart valve annulus. These radially outwardly extending structures clamp the native tissue between them and thereby help to anchor the prosthetic valve at the desired location in the patient.

  • Mitral valve loading tool
    Patent number: 10531954
    Abstract: A loading tool for loading a collapsible prosthetic heart valve into a delivery device may include a body extending in a longitudinal direction between a proximal end and a distal end, an extension on the distal end of the body, and a slot extending through the extension from a free end of the extension toward the distal end of the body. The body may include a lumen extending between the proximal end and the distal end, the body lumen having a first diameter. The extension may have a lumen coaxial with the body lumen, the extension lumen having a second diameter less than the first diameter so as to define a shelf surface between the proximal end of the body and the free end of the extension.

  • Stent Assembly For Use in Prosthetic Heart Valves
    Publication number: 20200008939
    Abstract: A prosthetic heart valve having a cuff attached to a stent provides a seal for preventing paravalvular leakage. The cuff may be constructed from known sealing materials to fill in and around paravalvular leakage gaps, while continuously collapsing down into a low profile volume within the stent. The cuff has a first cuff portion positioned on the luminal surface of the stent and a second cuff portion. The second cuff portion has a deployed configuration in which a region of the second cuff portion is spaced from the abluminal surface of the stent and an initial configuration different from the deployed configuration.

  • Stationary intra-annular halo designs for paravalvular leak (PVL) reduction—active channel filling cuff designs
    Patent number: 10500039
    Abstract: A prosthetic heart valve may include a collapsible and expandable stent extending in a flow direction between a proximal end and a distal end, a cuff attached to an annulus section of the stent and having an outer surface facing in a radial direction orthogonal to the flow direction, a plurality of prosthetic valve leaflets attached to the cuff, and a sealing structure attached to the annulus section of the stent at an inner edge of the sealing structure. The flow direction may be defined from the proximal end toward the distal end. The sealing structure may have an outer edge remote from the inner edge. The sealing structure may have a collapsed condition with the outer edge disposed adjacent the outer surface of the cuff and an expanded condition with the outer edge spaced apart from the outer surface of the cuff.

  • Valve assembly for crimp profile
    Patent number: 10470880
    Abstract: A method of assembling a prosthetic heart valve includes providing a collapsible and expandable stent having an annulus section and an aortic section. The annulus section has a first diameter in a relaxed condition and a second diameter less than the first diameter in a collapsed condition. A constraint is applied to the stent to constrain the annulus section to a predetermined diameter between the first and second diameters. Applying a cuff and/or a plurality of leaflets to the stent in the constrained condition enables less material to be used. The resultant prosthetic valve is therefore able to be collapsed to a smaller diameter for introduction into a patient.

A pattern of stitches may be circumferentially disposed around the flat bottom edge of the cuff, the pattern of stitches alternating between stitches sewn to the cuff only and stitches sewn to both the cuff and the stent.

  • Stent assembly for use in prosthetic heart valves
    Patent number: 10420641
    Abstract: A prosthetic heart valve having a cuff attached to a stent provides a seal for preventing paravalvular leakage. The cuff may be constructed from known sealing materials to fill in and around paravalvular leakage gaps, while continuously collapsing down into a low profile volume within the stent. The cuff is coupled circumferentially about the stent by members which may be in the nature of dimension and/or shape memory material having a tensioned and relaxed state. The members may be in the form of elongated elastic members or coiled members. When in the tensioned state, the cuff is located within the stent volume to provide a low profile prosthetic heart valve. Upon relaxing of the members, the cuff is pulled over the abluminal surface of the stent to form a cuff seal circumscribing the stent for preventing paravalvular leakage.

  • Prosthetic Heart Valves
    Publication number: 20190269508
    Abstract: A prosthetic heart valve (e.g., a prosthetic aortic valve) is designed to be somewhat circumferentially collapsible and then re-expandable. The collapsed condition may be used for less invasive delivery of the valve into a patient. When the valve reaches the implant site in the patient, it re-expands to normal operating size, and also to engage surrounding tissue of the patient. The valve includes a stent portion and a ring portion that is substantially concentric with the stent portion but downstream from the stent portion in the direction of blood flow through the implanted valve. When the valve is implanted, the stent portion engages the patient's tissue at or near the native valve annulus, while the ring portion engages tissue downstream from the native valve site (e.g., the aorta).

  • Collapsible and Re-expandable Prosthetic Heart Valve Cuff Designs and Complementary Technological Applications
    Publication number: 20190247184
    Abstract: A prosthetic heart valve is provided with a cuff having features which promote sealing with the native tissues even where the native tissues are irregular. The cuff may include a portion adapted to bear on the LVOT when the valve is implanted in a native aortic valve. The valve may include elements for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part of the cuff may be movable relative to the stent during implantation.
