20120035712 | METHOD AND APPARATUS FOR TRICUSPID VALVE REPAIR USING TENSION - Apparatus is provided, including a radially-expandable percutaneous implant, a tissue anchor, and a connecting element shaped so as to provide an annular loop surrounding a proximal portion of the tissue anchor in a manner which enables rotation of the anchor about a central longitudinal axis thereof when surrounded by the annular loop. The apparatus also includes a flexible longitudinal member coupled at a first portion thereof to at least a portion of the percutaneous implant and at a second portion to the connecting element. The annular loop of the connecting element facilitates rotation of the tissue anchor about the central longitudinal axis such that the anchor can rotate about the central longitudinal axis with respect to the annular loop, the flexible longitudinal member, and the percutaneous implant. Other applications are also described. | 02-09-2012 |
20130018459 | METHOD AND APPARATUS FOR TRICUSPID VALVE REPAIR USING TENSION - Apparatus is provided including a first tissue-engaging element, a first flexible longitudinal member coupled at a first end portion thereof to at least a portion of the first tissue-engaging element, and a first flexible-longitudinal-member-coupling element coupled to the first flexible longitudinal member at a second end portion of the first flexible longitudinal member. Apparatus includes a second tissue-engaging element, a second flexible longitudinal member coupled at a first end portion thereof to at least a portion of the second tissue-engaging element, and a second flexible-longitudinal-member-coupling element coupled to the second flexible longitudinal member at a second end portion of the second flexible longitudinal member, the first and second flexible-longitudinal-member-coupling elements being couplable to couple together the first and second flexible longitudinal elements. Other applications are also described. | 01-17-2013 |
20130046380 | TRICUSPID VALVE REPAIR USING TENSION - Apparatus is provided including a stent, which is configured to assume compressed and expanded states. The stent includes one or more elongated members, and two or more rings, which are coupled together by the one or more elongated members and by no other elements of the stent. The rings define respective planes that are generally perpendicular to the elongated members when the stent is in its expanded state. A longitudinal member, having a proximal end and a distal end, is coupled to the stent at the proximal end of the longitudinal member. A tissue anchor is coupled to the distal end of the longitudinal member. Other applications are also described. | 02-21-2013 |
20140114390 | TRICUSPID VALVE REPAIR USING TENSION - Apparatus is provided that includes first and second tissue-engaging elements, and first and second flexible longitudinal members, coupled at respective first end portions thereof to the first and the second tissue-engaging elements, respectively. The apparatus further includes a first flexible-longitudinal-member-coupling element coupled to a second end portion of the first flexible longitudinal member, a second flexible-longitudinal-member-coupling element coupled to a second end portion of the second flexible longitudinal member, and a flexible longitudinal guide member reversibly coupled to the first flexible-longitudinal-member-coupling element. The first and second flexible-longitudinal-member-coupling elements are configured to be couplable together to couple together the first and the second flexible longitudinal elements. Other applications are also described. | 04-24-2014 |
20150119936 | PERCUTANEOUS TETHER LOCKING - A tether-securing device is provided that includes a tubular element, which is shaped so as define a lateral wall that surrounds a lumen. The lateral wall is shaped so as to define a one-way locking opening. The tether-securing device further includes at least one tether, which (a) has at least a first tether end portion, and (b) passes through the lumen and the one-way locking opening. The tether-securing device additionally includes first and second tissue anchors. The first tissue anchor is connected to the first tether end portion. The one-way locking opening is configured to (a) allow sliding of the at least one tether in a first direction through the one-way locking opening, and (b) inhibit sliding of the at least one tether in a second direction opposite the first direction. Other embodiments are also described. | 04-30-2015 |
20150119979 | HEART VALVE REPAIR SYSTEM - Techniques are described for use with one or more sutures. For some applications, techniques are described for fixedly-coupling two or more sutures to each other. For some applications, such techniques are used for treating a heart valve of a subject. Techniques are also described for treating a heart valve of a subject by coupling leaflets of the heart valve to a support using tissue-piercing elements. Other embodiments are also described. | 04-30-2015 |
20150351910 | SOFT TISSUE ANCHORS AND IMPLANTATION TECHNIQUES - A tissue anchor (20) comprises a helical tissue-coupling element ( | 12-10-2015 |
20150374398 | LEAD EXTRACTION - Apparatus for removing a lead from a lumen of a subject including a flexible control tube shaped to define a control-tube lumen; and a flexible grasping tube shaped to define a grasping-tube lumen. The grasping tube is disposed within the control-tube lumen and includes a torque-transfer non-distal portion; and a helically-cut distal portion, that is (a) fixed at a distal end thereof to a distal end of the control tube, and (b) rotatable at least at a proximal end thereof with respect to the control tube. The helically-cut distal portion is configured to grasp the lead within the grasping-tube lumen upon the proximal end of the helically-cut distal portion being rotated with respect to the control tube. | 12-31-2015 |
