  • Publication number: 20080140190
    Abstract: An implant is sized and configured to be positioned in a left atrium above the plane of a native mitral heart valve annulus having leaflets. The implant, when deployed, engages a wall of the left atrium above the plane of the native mitral valve annulus to interact with movement of the leaflets of the mitral heart valve to affect mitral heart valve function. The implant is deployed into the left atrium through an intravascular access path that extends from a right atrium through a septum and into a left atrium.

  • Publication number: 20080140188
    Abstract: Devices, systems, and methods employ a heart implant structure that is sized and configured to be positioned in a left atrium above the plane of a native mitral heart valve annulus to affect mitral heart valve function. The implant structure includes a portion sized and configured to engage a wall of the left atrium above the plane of the native mitral valve annulus and to extend across the left atrium along a minor axis of the annulus.

  • Patent number: 7381220
    Abstract: Devices, systems and methods supplement, repair, or replace a native heart valve. The devices, systems, and methods employ an implant that, in use, extends adjacent a valve annulus. The implant includes a mobile neoleaflet element that occupies the space of at least a portion of one native valve leaflet. The implant mimics the one-way valve function of a native leaflet, to resist or prevent retrograde flow. The implant restores normal coaptation of the leaflets to resist retrograde flow, thereby resisting eversion and/or prolapse, which, in turn, reduces regurgitation.

  • Publication number: 20080065204
    Abstract: 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.

  • Publication number: 20060252984
    Abstract: Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial retrievability. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilize a bridge stop to secure the implant, and the methods of implantation employ various tools.

  • Publication number: 20060106456
    Abstract: Devices, systems, and methods employ an implant that is sized and configured to attach to the annulus of a dysfunctional heart valve annulus. In use, the implant extends across the major axis of the annulus above and/or along the valve annulus. The implant reshapes the major axis dimension and/or other surrounding anatomic structures. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets, which, in turn, reduces retrograde flow or regurgitation. The implant improves function to the valve, without surgically cinching, resecting, and/or fixing in position large portions of a dilated annulus, or without the surgical fixation of ring-like structures.

  • Publication number: 20060069430
    Abstract: Devices, systems and methods retain a native heart valve leaflet to prevent retrograde flow. The devices, systems, and methods employ an implant that, in use, rests adjacent a valve annulus and includes a retaining structure that is sized and shaped to overlay at least a portion of one or more native valve leaflets. The retaining structure retains the leaflet or leaflets it overlays, to resist leaflet eversion and/or prolapse. In this way, the implant prevents or reduces regurgitation. The implant does not interfere significantly with the opening of and blood flow through the leaflets during periods of antegrade flow.

  • Publication number: 20050228495
    Abstract: A valve prosthesis is sized and configured to rest within a blood path subject to antegrade and retrograde blood flow. A trestle element on the prosthesis extends across the blood path. A leaflet assembly is suspended from the trestle element and extends into the blood path in alignment with blood flow. At least one mobile leaflet member on the leaflet assembly is sized and configured to assume orientations that change according to blood flow direction. The mobile leaflet member has a first orientation that permits antegrade blood flow and a second orientation that resists retrograde blood flow. The valve prosthesis, when implanted in a heart chamber or great vessel, serves to supplement and/or repair and/or replace native one-way heart valve function.

  • Publication number: 20050228468
    Abstract: Devices, systems and methods establish scaffold-like structures within the heart or a body cavity. The scaffold-like structures establish a stable platform that makes it possible to accomplish a desired therapeutic and/or diagnostic objective in a targeted fashion in one or more tissue regions. The desired therapeutic and/or diagnostic objectives can include, e.g., (i) the delivery of various chemical, drug, and/or biological agents (in liquid, gel, or wafer form) into contact on or in the tissue regions, to accomplish, e.g., ablation or other therapeutic objectives in a controlled, precise fashion; and/or (ii) the delivery of mechanical, heat, cooling, or electrical energy to the tissue region—e.g.

  • Publication number: 20050216079
    Abstract: A heart valve implant has a body sized and configured to rest near or within a heart valve annulus. A plurality of spaced-apart retainers extend outwardly from the body to contact tissue near or within the heart valve annulus. The retainers are sized and configured to secure the body to the heart valve annulus. The implant can be secured, e.g., without the use of sutures.

  • Patent number: 6893459
    Abstract: A method of implanting a universal heart valve prosthetic anchor device for receipt of a mating occluder. The anchor device includes a pair of rings axially shiftable from a retracted to a deployed position. The anchor device further formed with a plurality of flexible retaining elements received within the anchor rings and which are capable of laterally downwardly outward movement upon deployment of the rings. The deployment tool includes an elongated tubular housing mounted at its distal end with radially outwardly diverging tines for reversible engagement with the anchoring rings. A wire is telescoped through the tines for actuation of the fork thereby causing deployment of the anchoring rings. Once placed at the desired location within the heart muscle, the deployment tool is actuated causing the anchor device to shift axially thereby causing the retainers to deploy outwardly and upwardly to secure the valve anchor in place at the heart valve annulus shelf.
