Patent number: 9839519Abstract: 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.Type: GrantFiled: February 27, 2013Date of Patent: December 12, 2017Assignee: VALCARE, INC.Inventors: Samuel M.

Publication number: 20170042670Abstract: 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.

Publication number: 20160331534Abstract: 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.Type: ApplicationFiled: June 28, 2016Publication date: November 17, 2016Applicant: VALCARE, INC.Inventors: Maurice Buchbinder, Samuel M.

Patent number: 8821570Abstract: Annuloplasty rings are employed to treat heart valve defects, such as regurgitation. Synching the heart tissue to the ring restores the valve opening to its approximate original size and operating efficiency. Adjustable annuloplasty rings allow for a proper degree of synching both during open heart surgery and over the patient's lifetime. A subcutaneous port may be coupled to an adjustable annuloplasty ring such that an external activation energy generator can be used to heat the adjustable annuloplasty ring and thereby adjust the size of the annuloplasty ring.Type: GrantFiled: July 20, 2010Date of Patent: September 2, 2014Assignee: MiCardia CorporationInventors: Jeffrey P.
