Methods for securing a transcatheter valve to a bioprosthetic cardiac structure

A spacer for creating a docking station for a transcatheter heart valve is provided. The spacer changes an effective diameter and/or a shape of an implanted bioprosthetic structure such as a bioprosthetic heart valve or annuloplasty ring, providing a supporting structure into which the transcatheter valve expands without over expanding. The spacer may be deployed through an interventional technique either through transseptal access, transfemoral access, or transapical access and is typically deployed at least in part on an inflow portion of the implanted bioprosthetic structure.

CATHETER FOR MANIPULATING ANATOMICAL STRUCTURE AND RELATIVE POSITION OF THE CATHETER AND THE ANATOMICAL STRUCTURE
20220409373 · 2022-12-29 ·

A catheter for changing or manipulating a shape of a surrounding anatomical structure or position the catheter in relation to said surrounding anatomical structure has distal and proximal ends. Further the catheter includes at least a first body extending along the catheter in the distal end portion of the catheter, wherein said body has an activated state and inactivated state. In said activated state a second diameter or a second volume of the body is bigger than a first diameter or a first volume of the body in said inactivated state. In addition, in said activated state said body is configured to support the catheter to an anatomical structure surrounded the catheter, such as e.g. chordae, blood vessel or urethra, and thereby change a relative position of the catheter and the surrounding anatomical structure and again to change or manipulate the shape of the surrounding anatomical structure or position the catheter in relation to said surrounding anatomical structure.

Stabilizing and adjusting tool for controlling a minimally invasive mitral / tricuspid valve repair system

Disclosed herein are embodiments related to a method for performing a minimally invasive procedure, the method including delivering an annuloplasty ring in a linear shape using a delivery system. In some embodiments, the delivery of the annuloplasty ring may utilize a trans-septal approach or a trans-apical. In some embodiments, the delivery system may position the annuloplasty ring using a flexible stabilizing mechanism and/or activate one or more anchors to extend outward from the annuloplasty ring.

11517435 · 2022-12-06 · ·

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.

ENHANCED FLEXIBILITY ANNULOPLASTY BANDS
20220370200 · 2022-11-24 ·

An annuloplasty band having a differentiation in area moment of inertia, where the area moment of inertia in the out of plane direction is much less than the area moment of inertia in the plane of the annulus. This makes the band stiff enough to hold the annulus in the correct shape while being flexible enough out of plane to minimize the risk of suture dehiscence or breakage. One example is a C-shaped band with a core formed of nitinol and having a constant cross-section with a wider radial dimension than an axial dimension. The cross-section may be rectangular. The band is asymmetric across a minor axis with one end extending around the anterior side farther than the other. The free ends rise up from adjacent lateral sides, and a continuous posterior mid-section also rises upward.

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.

A method is provided, including treating a heart valve of a patient by implanting at the heart valve an implant including an elongate element including at least in part a tension element, by placing the implant at the heart valve of the patient, and subsequently to the placing, increasing tension of the elongate element at least in part. The tension element is configured to undergo conformational changes, subsequently to the placing, responsively to a cardiac cycle of the patient. Implanting the implant includes implanting the implant such that the tension element undergoes the conformational changes responsively to the cardiac cycle of the patient in a manner in which the tension element cyclically increases and decreases pressure applied to at least one leaflet of the heart valve by the elongate element.
