  • Publication number: 20190133765
    Abstract: Systems and methods for percutaneous, transcatheter heart valve repair are disclosed. A system may include a catheter, an adjustable ring, and a stabilizer. The adjustable ring may include a body member that is transitionable from an insertion geometry to an operable geometry. The insertion geometry may be configured to allow percutaneous passage of the ring into the heart. The operable geometry may have an expanded state to conform to an annulus of a target valve and a contracted state to reduce a diameter of the annulus. The adjustable ring may also include a plurality of anchors deployable in the operable geometry to engage the annulus. The stabilizer may include a plurality of prongs configured to engage the ring in the operable geometry within the heart to enable percutaneous manipulation of the ring to orient and position the ring in intimate contact with the annulus.

  • Publication number: 20190083239
    Abstract: An implantable valve replacement system for a cardiovascular valve may include an adjustable stabilizing ring. The stabilizing ring may be composed of a body member that is transitionable from an elongate insertion geometry to an annular operable geometry. The stabilizing ring may further include a plurality of anchors deployable in the annular operable geometry to engage the annulus of the cardiovascular valve. The ring may be used in conjunction with an implantable valve frame. The valve frame may be located within the ring and the ring, in turn, may be stabilized through the anchors engaging the valve annulus. The valve replacement system may be applied by engaging the ring in its annular operable geometry with the valve annulus through the anchors. The valve frame may be inserted through the opening of the ring, thereby forming a stabilizing mechanical contact between the frame and the annulus.

  • Publication number: 20180161160
    Abstract: Apparatus, systems, and methods are provided for repairing heart valves through percutaneous transcatheter delivery and fixation of annuloplasty rings to heart valves. An annuloplasty ring includes an outer hollow body member including a plurality of regions. Adjacent regions cooperate with one another to change the body member from an elongate insertion geometry to an annular operable geometry. Adjacent regions are coupled by a biasing element or a stepped connector to allow expansion to an expanded state and contraction to a contracted state in the annular operable geometry. The annuloplasty ring also includes an internal anchor member located at least partially within the body member and having a plurality of anchors configured to attach the annuloplasty ring to tissue of a heart valve annulus. An angled ring closure lock allows coupling of the ends of an annuloplasty ring at an apex of a D-shape annular operable geometry.

  • Publication number: 20160331534
    Abstract: Apparatus, systems, and methods are provided for repairing heart valves through percutaneous transcatheter delivery and fixation of annuloplasty rings to heart valves via a trans-apical approach to accessing the heart. A guiding sheath may be introduced into a ventricle of the heart through an access site at an apex of the heart. A distal end of the guiding sheath can be positioned retrograde through the target valve. An annuloplasty ring arranged in a compressed delivery geometry is advanced through the guiding sheath and into a distal portion of the guiding sheath positioned within the atrium of the heart. The distal end of the guiding sheath is retracted, thereby exposing the annuloplasty ring. The annuloplasty ring may be expanded from the delivery geometry to an operable geometry. Anchors on the annuloplasty ring may be deployed to press into and engage tissue of the annulus of the target valve.
