ADJUSTABLE PERCUTANEOUS ANNULOPLASTY DEVICES, DELIVERY SYSTEMS, A METHOD FOR PERCUTANEOUSLY DEPLOYING AN ANNULOPLASTY DEVICEA AND A METHOD PERFORMED BY ONE OR MORE PROCESSING DEVICES
An adjustable annuloplasty device (1) which comprises a tubular, longitudinally extending cage (2) having a basically annular shape or being adapted to be brought into an annular shape upon release from a delivery device (3). The annuloplasty device additionally comprises a separate, tubular, longitudinally extending base (4) having at least a part of the basically annular shape of the cage (2) or being adapted to be brought into at least partially into the annular shape of the cage (2) upon release from a delivery device. The tubular cage (2) is attachable to the base (4) and the base (4) is flexible such that the annular shape of the base (4) is adjustable.
DELIVERY DEVICE FOR AN ANNULOPLASTY IMPLANT
A delivery device for an annuloplasty implant is disclosed comprising an outer sheath, a delivery wire being movable within said sheath in a longitudinal direction thereof, a holder being releasably connectable to said implant, said holder being pivotably connected to a distal portion of said delivery wire, wherein said holder is folded inside said outer sheath in a delivery configuration, and wherein said holder is foldable from said delivery configuration to an expanded deployed configuration outside said outer sheath. A system comprising such delivery device and an annuloplasty implant, and a method of delivering such implant is also disclosed.
SYSTEMS AND METHODS FOR HEART VALVE THERAPY
Prosthetic mitral valves described herein can be deployed using a transcatheter mitral valve delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native mitral valve. This document describes prosthetic heart valve designs that interface with native mitral valve structures to create a fluid seal, thereby minimizing mitral regurgitation and paravalvular leaks. This document also describes prosthetic heart valve designs and techniques to manage blood flow through the left ventricular outflow tract. In addition, this document describes prosthetic heart valve designs and techniques that reduce the risk of interference between the prosthetic valves and chordae tendineae.
Device And Method For Improving Function Of Heart Valve
A device for improving the function of a heart valve comprises a first loop-shaped support, which is configured to abut a first side of the heart valve, and a first flange unit being connected to said first loop-shaped support. The flange unit is configured to be arranged against said annulus when said first loop-shaped support is abutting said heart valve.
HEART VALVE REPAIR
In some examples, the disclosure describes annuloplasty devices, systems, and methods involving one or more flexible elongated elements attached to one or more anchors secured proximate an annulus of a cardiac or vascular valve. In some examples one or more anchors are proximate a first side of a valve annulus. One or more flexible elements attached to the anchors are tightened to pull the first side closer to a second side of the annulus, thus reducing a dimension of the annulus. In some examples, an annuloplasty system includes an annuloplasty ring and one or more anchors configured to attach the ring proximate a valve annulus. The ring may include permanently deformable section that can be deformed after implantation to change a dimension of a corresponding valve annulus.
STABILIZING AND ADJUSTING TOOL FOR CONTROLLING A MINIMALLY INVASIVE MITRAL / TRICUSPID VALVE REPAIR SYSTEM
Disclosed herein are embodiments related to a method for performing a minimally invasive procedure, the method including delivering an annuloplasty ring in a linear shape using a delivery system. In some embodiments, the delivery of the annuloplasty ring may utilize a trans-septal approach or a trans-apical. In some embodiments, the delivery system may position the annuloplasty ring using a flexible stabilizing mechanism and/or activate one or more anchors to extend outward from the annuloplasty ring.
Thrombus Management And Structural Compliance Features For Prosthetic Heart Valves
A prosthetic heart valve can include an outer support assembly, an inner valve assembly, which define between them an annular space, and a pocket closure that bounds the annular space to form a pocket in which thrombus can be formed and retained. Alternatively, or additionally, the outer support assembly and the inner valve assembly can be coupled at the ventricle ends of the outer support assembly and the inner valve assembly, with the outer support assembly being relatively more compliant in hoop compression in a central, annulus portion than at the ventricle end, so that the prosthetic valve can seat securely in the annulus while imposing minimal loads on the inner valve assembly that could degrade the performance of the valve leaflets.
MITRAL VALVE TREATMENT TECHNIQUES
A method is provided, including treating a heart valve of a patient by implanting at the heart valve an implant including an elongate element including at least in part a tension element, by placing the implant at the heart valve of the patient, and subsequently to the placing, increasing tension of the elongate element at least in part. The tension element is configured to undergo conformational changes, subsequently to the placing, responsively to a cardiac cycle of the patient. Implanting the implant includes implanting the implant such that the tension element undergoes the conformational changes responsively to the cardiac cycle of the patient in a manner in which the tension element cyclically increases and decreases pressure applied to at least one leaflet of the heart valve by the elongate element.
Methods of implanting an annuloplasty ring for reduced dehiscence
A prosthetic remodeling annuloplasty ring for use in tricuspid or mitral valve repairs to provide support after annuloplasty surgery. The annuloplasty ring includes a relatively rigid core extending around an axis that is discontinuous to define two free ends. A suture-permeable interface surrounding the core includes floppy regions adjacent both free ends of the core. Sutures are used to attach the annuloplasty ring to the annulus, including at least one suture through each of the floppy regions to secure the free ends of the ring and minimize the risk of ring dehiscence, or pull through of the sutures through the annulus tissue. The floppy regions may project from each free end into the gap toward each other, be radially enlarged such as paddle-like extensions, or may comprise outwardly lateral extensions at the free ends of the core.
