Devices are disclosed for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the mitral valve and an edge to edge device. Methods are disclose for reducing mitral valve regurgitation at low left ventricle pressure and high left ventricle pressure during the cardiac cycle. Devices are disclosed for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the mitral valve with an adaptive coaptation element.
Device, system, and method for transcatheter treatment of valvular regurgitation
The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the valve; a system including the coaptation assistance element and anchors for implantation; a system including the coaptation assistance element and delivery catheter; and a method for transcatheter implantation of a coaptation element across a heart valve.
Surgery for correcting tricuspid valve regurgitation
A method is presented for tricuspid valve commissural annuloplasty for secondary tricuspid insufficiency. The method comprises suturing through a valve annulus, and bringing the valve annulus to its normal size while eliminating its regurgitation. The suturing comprises applying individual sutures on pledgets through the tricuspid valve annulus from a right ventricle side along anteroposterior and posteroseptal commissures on both sides of each of said commissures, spaced-apart from them; taking out needles of said sutures from a right atrium side and tying knots along the commissures between them.
Ring-based prosthetic cardiac valve
A prosthetic cardiac valve assembly and method of implanting the same is disclosed. In certain disclosed embodiments, the prosthetic valve assembly is an annuloplasty ring with an attached artificial valve. The prosthetic valve assembly can be secured to native heart tissue by suturing or other suitable method of the annuloplasty ring to the native heart tissue. The prosthetic valve leaflets of the prosthetic valve can also be anchored to the native heart tissue to prevent prolapse. In certain embodiments, the prosthetic valve leaflets are anchored to the native papillary muscles. In still other embodiments, the prosthetic valve assembly contains exactly the number of prosthetic valve leaflets as are in the native valve that the prosthetic valve assembly is configured to replace. With the prosthetic valve assembly properly positioned, it will replace the function of the native valve.
Annuloplasty implant
An annuloplasty implant is disclosed comprising first and second support rings arranged in a coiled configuration around an axial direction, and being adapted to be arranged on opposite sides of native heart valve leaflets to pinch said leaflets. At least part of said first and second support ring is formed from a carbon fiber material. The first and second support rings are resiliently movable with respect to each other in opposite directions along said axial direction. A method of manufacturing an annuloplasty implant is also disclosed.
Cardiac valve repair devices with annuloplasty features and associated systems and methods
Cardiac valve repair devices with annuloplasty features and associated systems and methods are disclosed herein. A cardiac valve repair device configured in accordance with embodiments of the present technology can include, for example, an atrial fixation member configured to engage tissue within a left atrium proximate to a native mitral valve and a spring mechanism coupled to an inferior edge portion of the atrial fixation member. The spring mechanism has an extended state with a first length corresponding to a dimension of the atrial fixation member in a deployed state and a relaxed state with a shorter length corresponding to a desired dimension of the native valve annulus. When implanted, the spring mechanism contracts the atrial fixation member such that the native mitral annulus anchored to the atrial fixation member reduces in a cross-sectional dimension.
IMPLANT FOR HEART VALVE
A heart valve repair system includes a delivery sheath and an implant that includes a frame having a surface configured to contact an upstream surface of a native heart valve. First and second gripping members are coupled to the frame and each (1) includes first and second arms and (2) is configured to clamp a respective native leaflet. The implant is disposed in the sheath in a delivery state in which the frame defines a wall fully surrounding a central longitudinal axis of the implant. The distal end of the wall defines a distal opening of the frame. The distal end of the wall is disposed proximally to the entire first tissue-engaging surface of each of the gripping members and proximally to the entire second tissue-engaging surface of each of the gripping members. Other embodiments are also described.
PROSTHETIC HEART VALVE
Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve can include an annular frame having an inflow end, an outflow end and a central longitudinal axis extending from the inflow end to the outflow end. The valve can include a support layer, where a first portion of the support layer extends circumferentially around the central longitudinal axis along an outer surface of the frame and a second portion of the support layer extends circumferentially around the central longitudinal axis axially beyond the inflow end of the frame. The valve can further include a valvular structure, where at least a portion of the valvular structure is connected to the second portion of the support layer and is unsupported by the frame.
SURGICAL PADS AND SPACERS
A surgical pad can comprise a flexible pad portion configured to be positioned over an opening in a target tissue. A plurality of elongate ribs can be distributed across a surface of the flexible pad portion oriented away from the target tissue and can be coupled to the flexible pad portion. A surgical pad can comprise a central opening configured to be aligned with an opening in a target tissue, and a plurality of edge openings distributed around an outer edge portion. A method can comprise positioning a spacer between a target tissue and a surgical pad to adjust the tension of surgical cords secured to surgical pad. A method can comprise positioning a spacer between a surface of a surgical pad oriented away from a target tissue and portions of surgical cords secured over the surface of the surgical pad, to adjust the tension of the surgical cords.
Prosthesis with anti-paravalvular leakage component including a one-way valve
A transcatheter prosthesis includes a stent, a prosthetic valve component, and an anti-paravalvular leakage component. The anti-paravalvular leakage component is coupled to the stent and includes an inner skirt, an outer wrap, a cavity, an opening, and a one-way valve. The inner skirt is disposed on an inner surface of the stent and has an inflow end and a downstream end. The outer wrap is disposed around an outer surface of the stent and has an inflow end coupled to the inflow end of the inner skirt and a downstream end. The cavity is formed between an outer surface of the inner skirt and an inner surface of the outer wrap. An opening is disposed between the inner skirt and the outer wrap. The one-way valve includes a flap at the opening configured to open to allow blood flow into the cavity but prevent blood flow out of the cavity.
