  • Publication number: 20240081996
    Abstract: The present disclosure relates to an annuloplasty device configured for being implanted via a catheter, a cinching device applied in annuloplasty, and a method of implementing annuloplasty. The annuloplasty device comprises a shaping ring and a tissue anchoring element. The shaping ring includes a first bar member, a second bar member and a third bar member that are connected via an extendable and compressible element. The first bar member, the second bar member and the third bar member are each provided with a connection portion for anchoring the shaping ring to the physiological tissue by the tissue anchoring element. An adjustment wire is provided in an inner cavity of the extendable and compressible element, for adjusting the size of the shaping ring, thereby adjusting the size of the physiological annulus.

  • Publication number: 20240000570
    Abstract: An exemplary system for delivering annuloplasty implants includes an elongated inner catheter assembly, a manifold attached to the proximal portion of the inner catheter, a steering knob assembly coupled to the manifold, a torquer control knob assembly coupled to the manifold, and a central lead extending from a proximal portion of the torquer control knob assembly to the distal portion of the inner catheter assembly. The manifold is configured to present a medial driver tube, a lateral driver tube, a medial lead, a lateral lead, a medial tether puller and a lateral tether puller to a surgeon. Additional annuloplasty implant instrumentation and methods of use are also disclosed.

  • Publication number: 20230355392
    Abstract: An exemplary method of performing an annuloplasty procedure includes introducing a catheter into a left atrium of a heart, deploying first and second members from the catheter and anchoring them to an anterior side of a mitral valve, and deploying a third member from the catheter and anchoring it to a posterior side of the mitral valve. The first member has a first flexible tensile member attached and the second member has a second flexible tensile member attached. The third member slidably tracks over the first and the second flexible tensile members when it is being deployed. Tension is applied to the first and the second tensile members to draw the first member and the second member toward the third member, thereby bringing the posterior side and the anterior side of the mitral valve annulus into closer approximation. Annuloplasty systems, devices and components are also disclosed.

  • Patent number: 11672661
    Abstract: An exemplary method of performing an annuloplasty procedure includes introducing a catheter into a left atrium of a heart, deploying a first member from the catheter, anchoring the first member to a posterior side of a mitral valve annulus in the left atrium, deploying a second member from the catheter, anchoring the second member to an anterior side of the mitral valve annulus in the left atrium, deploying a flexible tensile member from the catheter, attaching the tensile member to both the first member and the second member and applying tension to the tensile member to draw the first member and the second member toward one another and bring the posterior side and the anterior side of the mitral valve annulus into closer approximation. Annuloplasty systems and components are also disclosed.

  • Publication number: 20170325943
    Abstract: A method for reducing an axial profile of a valve implant includes providing a valve implant having a longitudinal axis and a delivery catheter having a central axis and a distal receiving section. The method further includes helically rolling the valve implant around a rolling axis that is offset at an angle of about 15 degrees to about 60 degrees with respect to the longitudinal axis to form a rolled valve implant having a rolled axis, where the rolled axis is the same as the rolling axis. The method further includes aligning the rolled axis of the rolled valve implant with the central axis of the delivery catheter. The method further includes inserting the rolled valve implant into the distal receiving section of the delivery catheter.
