20120022557 | MULTIPLE ANCHOR DELIVERY TOOL - An anchor deployment tool includes a flexible outer tube, within which is positioned a flexible inner shaft, and a rotating deployment element coupled to a distal end of the shaft. The tool is configured to provide an anchor storage area, which initially stores a plurality of tissue anchors, such that the inner shaft passes through channels of the anchors along entire longitudinal lengths of the anchors, and the anchors are within the outer tube. The rotating deployment element is configured to directly engage the anchors in the anchor storage area one at a time, advance each of the anchors while engaged in a distal direction, and deploy each of the anchors through the distal tube end and into tissue of a subject. Other embodiments are also described. | 01-26-2012 |
20120022640 | TECHNIQUES FOR PERCUTANEOUS MITRAL VALVE REPLACEMENT AND SEALING - Apparatus and methods are described, including one or more valve support guide members that are delivered to one or more commissures of a native atrioventricular valve of a patient. A prosthetic valve support is advanced toward the native valve along the one or more valve support guide members and placed at the native valve. A prosthetic valve is coupled to the valve support. One or more sealing elements facilitate sealing of an interface between the prosthetic valve support and the native valve. Other applications are also described. | 01-26-2012 |
20120022644 | PARTIALLY-ADJUSTABLE ANNULOPLASTY STRUCTURE - Apparatus and methods are described including an annuloplasty structure configured for implantation along an annulus of an atrioventricular valve of a heart of a subject. The structure includes a coiled element comprising at least one first portion thereof which is flexible and longitudinally compressible, and at least one second portion thereof in series with the first portion, the second portion being flexible and less longitudinally compressible than the first portion. Other applications are also described. | 01-26-2012 |
20120330410 | CLOSURE ELEMENT FOR USE WITH AN ANNULOPLASTY STRUCTURE - Apparatus and methods are described including an implant structure configured to treat a native atrioventricular valve of a patient, the implant structure including a sleeve having a lumen and at least one end, the at least one end being shaped so as to define an opening. A closure element is disposed in a vicinity of the at least one end, the closure element being configured to facilitate closure of the opening. A contracting mechanism is coupled to the implant structure and configured to contract at least a contraction-facilitated portion of the implant structure. Other applications are also described. | 12-27-2012 |
20120330411 | CLOSED BAND FOR PERCUTANEOUS ANNULOPLASTY - An implantable structure includes a flexible sleeve, having first and second sleeve ends, and a contracting assembly, which is configured to longitudinally contract the sleeve, and includes a contracting mechanism, which is disposed longitudinally at a first site of the sleeve, and a longitudinal contracting member, having (a) a first member end, (b) a second member end, which is coupled to the sleeve longitudinally at a second site longitudinally between the first site and the second sleeve end, exclusive, and (c) a first member end portion, which is coupled to the contracting mechanism. The sleeve is arranged in a closed loop, such that first and second portions of the sleeve together define a longitudinally overlapping portion of the sleeve. The implantable structure is configured such that the contracting assembly longitudinally applies a longitudinal contracting force only between the first and the second sites, and not along the overlapping portion. | 12-27-2012 |
20130035759 | TECHNIQUES FOR PERCUTANEOUS MITRAL VALVE REPLACEMENT AND SEALING - Apparatus is described for use with a native heart valve of a subject, the apparatus including (1) a prosthetic valve support, comprising an upstream support portion, the upstream support portion having (a) a compressed configuration and an uncompressed configuration in which the upstream support portion has an inner perimeter that defines an opening; and (2) a prosthetic valve, advanceable into the opening defined by the upstream support portion, and intracorporeally couplable to the upstream support portion by being expanded within the opening defined by the upstream support portion, the apparatus being configured such that, when the prosthetic valve is expanded within the opening defined by the upstream support portion, the expansion of the prosthetic valve is restricted by the inner perimeter of the upstream support portion, without causing the prosthetic valve support to apply a radially-expansive force to the native annulus. Other embodiments are also described. | 02-07-2013 |
20130172992 | TECHNIQUES FOR PERCUTANEOUS MITRAL VALVE REPLACEMENT AND SEALING - Apparatus and methods are described including a prosthetic valve support ( | 07-04-2013 |
20140094903 | IMPLANTATION OF REPAIR CHORDS IN THE HEART - Apparatus is provided, including first and second longitudinal members coupled at respective first portions thereof to tissue surrounding the ventricle. The first portion of at least the first longitudinal member is coupled to a tissue anchor, and respective second portions of the first and second longitudinal members are coupled to respective first and second leaflets of a cardiac valve. The longitudinal members are arranged with respect to the tissue anchor and the portion of tissue surrounding the ventricle in a manner which facilitates adjustment of a degree of tension of the first and second longitudinal members to draw the first and second leaflets together. A longitudinal-member-coupling device is coupled to the first and second longitudinal members, and is advanceable toward a ventricular surface of the first and second leaflets, and responsively to draw together the first and second longitudinal members. Other applications are also described. | 04-03-2014 |
20140257475 | PERCUTANEOUS MITRAL VALVE REPLACEMENT AND SEALING - Apparatus is provided for use with a prosthetic valve for implantation at a native valve of a subject, the native valve including at least one native leaflet, the apparatus including (1) a prosthetic valve support, including (a) an upstream support portion, being configured to be placed against an upstream side of the native valve, and having an inner perimeter that defines an opening that is configured to receive the prosthetic valve, and (b) at least one clip (i) comprising at least two clip arms and a clip-controller interface, the clip-controller interface being coupled to at least one of the clip arms, and (ii) being configured to be coupled to a native leaflet of the native valve; and (2) at least one clip controller, reversibly couplable to the clip-controller interface, and configured to facilitate opening and closing of the clip. Other embodiments are also described. | 09-11-2014 |
20140324164 | TECHNIQUES FOR PERCUTANEOUS MITRAL VALVE REPLACEMENT AND SEALING - Apparatus is provided for use with a native valve of a heart of a subject, the apparatus including (1) an annular upstream support portion, configured to be transluminally placed against an atrial surface of the native valve; (2) a tissue-engaging element that includes a coupling portion configured to be transluminally coupled to tissue in a ventricle of the heart; (3) an elastically-stretchable holding element, configured to secure the upstream support portion against the atrial surface by elastically coupling the coupling portion to the upstream support portion; and (4) a prosthetic valve, configured to be transluminally delivered to the native valve and intracorporeally coupled to the upstream support portion subsequently to the securing of the upstream support portion against the atrial surface. Other embodiments are also described. | 10-30-2014 |
