Publication number: 20120035721Abstract: A temporary subvalvular check valve has a collar and an expandable seal structure connected by pivotable struts that together support flexible leaflets. The check valve can be introduced along a tool shaft and positioned in a chamber or vasculature by expanding the seal structure against an adjacent wall. Cardiac function is augmented during valve procedures, such as valve excision, valve implantation, or valve leaflet replacement, by placing the temporary check valve just upstream of the valve being treated. The temporary check valve is collapsible so that it can be inserted through a small incision or port in the apex of the heart or through the aorta, into the ventricular cavity. Such a system thus does not require arrest or pacing of the heart and will allow such valve repair or replacement procedures to be done without concern for time or compromise to the patients' physiology.Type: ApplicationFiled: August 9, 2011Publication date: February 9, 2012Applicant: ValveXchange, Inc.Inventor: Ivan Vesely

Patent number: 8100964Abstract: Valve repair apparatus and methods for ensuring proper coaptation and operation of the leaflets of a heart valve. Main aspects of the disclosure relate to devices including a support member configured for attachment to the heart valve annulus, a post extending from the support member away from the plane of the annulus and a connector coupled with the post and configured for attachment to at least one of the leaflets. The various embodiments may include a replacement heart valve connected with the support member for facilitating full replacement as opposed to near repair of an existing native heart valve. Various other devices include support structure and one or more posts connected to opposite sides of the support structure and extending from one side of the valve annulus to another to modify the shape of the annulus.Type: GrantFiled: March 13, 2009Date of Patent: January 24, 2012Assignee: Cardiac Valve Technologies LLCInventor: Paul A.

Publication number: 20120010701Abstract: An annuloplasty ring to resize a dilated aortic root during valve sparing surgery includes a scalloped space frame having three trough sections connected to define three crest sections. The annuloplasty ring is mounted outside the aortic root, and extends in height between a base plane and a spaced apart commissure plane of the aortic root. At least two adjacent trough sections are coupled by an annulus-restraining member or tether that limits the maximum deflection of the base of the annuloplasty ring. In use, the tether is preferably located in proximity to the base plane of the aortic root. The annuloplasty ring is movable between a first, substantially conical configuration occurring during a diastolic phase of the cardiac cycle, and a second, substantially cylindrical configuration occurring during a systolic phase of the cardiac cycle.Type: ApplicationFiled: September 8, 2011Publication date: January 12, 2012Applicant: CORONEO, INC.Inventors: Neil Bulman-Fleming, Raymond Cartier, Valerio Valentini, Anthony Paolitto

Publication number: 20120010700Abstract: A method for implanting a prosthetic valve apparatus in a novel location which replaces the function of a native diseased valve. The prosthetic valve apparatus includes a one way valve and an expandable valve seating. anchoring and securing apparatus in a newly created orifice near or at the center of the anterior valve leaflet. The prosthetic valve apparatus also causes the sealing of the native valve and thus results in a solution for paravalvular leakage and regurgitation.Type: ApplicationFiled: July 8, 2010Publication date: January 12, 2012Inventor: Benjamin Spenser

Patent number: 8092525Abstract: A method according to one embodiment may include providing a heart valve implant including an anchor capable of engaging coronary tissue, a shaft coupled to said anchor, and a valve body coupled to said shaft. The method may further include at least partially collapsing the heart valve implant and percutaneously inserting the heart valve implant into a heart. The percutaneously inserted implant may be secured within the heart and may then be expanded. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.Type: GrantFiled: October 26, 2005Date of Patent: January 10, 2012Assignee: Cardiosolutions, Inc.Inventors: Kenneth Arden Eliasen, Steven J.

DEVICES, SYSTEMS, AND METHODS FOR SUPPLEMENTING, REPAIRING OR REPLACING A NATIVE HEART VALVE LEAFLET
Publication number: 20110319990Abstract: An implant for supplementing, repairing, or replacing a native heart valve leaflet or leaflets provides a scaffold, which defines a pseudo-annulus. The implant further has at least two struts in generally oppositely spaced apart positions on the scaffold. The scaffold can be placed in an elastically loaded condition in a heart with the struts engaging tissue at or near the leaflet commissures of a heart valve annulus, to reshape the annulus for leaflet coaptation. The implant further provides a neoleaflet element coupled to the scaffold within pseudo-annulus, to provide a one-way valve function.Type: ApplicationFiled: September 8, 2011Publication date: December 29, 2011Applicant: MVRx, INC.Inventors: John A.

Publication number: 20110301704Abstract: A remodeling mitral annuloplasty ring with a reduced anterior-to-posterior dimension to restore coaptation between the mitral leaflets in mitral valve insufficiency (IMVI). The ring has a generally oval shaped body with a major axis perpendicular to a minor axis, both perpendicular to a blood flow axis. An anterior section lies between anteriolateral and posteriomedial trigones, while a posterior section defines the remaining ring body and is divided into P1, P2, and P3 segments corresponding to the three scallops of the same nomenclature in the posterior leaflet of the mitral valve. The anterior-to-posterior dimension of the ring body is reduced from conventional rings; such as by providing, in atrial plan view, a pulled-in P3 segment. Viewed another way, the convexity of the P3 segment is less pronounced than the convexity of the P1 segment. In addition, the ring body may have a downwardly deflected portion in the posterior section, preferably within the P2 and P3 segments.Type: ApplicationFiled: April 26, 2011Publication date: December 8, 2011Applicant: EDWARDS LIFESCIENCES CORPORATIONInventors: Ottavio Alfieri, Alain F.
