Flexible canopy valve repair systems and methods of use
A system for treating valvular regurgitation in a heart valve includes a flexible canopy and an elongated tether including an elastic portion and an inelastic portion. When the system is in a deployed configuration, a proximal end of the flexible canopy is coupled to an annulus of the heart valve and a distal end of the elongated tether is coupled to a ventricle. The flexible canopy is configured to overlay a first native leaflet of the heart valve, and tension on the elongated tether is applied and/or adjusted to prevent the first leaflet from prolapsing, to maximize coaptation of the flexible canopy with a second native leaflet of the heart valve, and to minimize regurgitation of the heart valve.
Fistula treatment device
A fistula treatment system comprises a guide such as a guide coil 1101 which is adapted to extend partially around a tissue tract and an implant element 1102. The implant element 1102 is activated to draw tissue surrounding the tract inwardly.
SELF-LOCKING WINCH
A system includes a transcatheterally-advanceable driver and an implant. The implant includes a winch, and a tether that has an end portion. The winch includes a spool, a mount, and a driver interface engageable and drivable by the driver. The mount is coupled to the driver interface such that driving of the driver interface by the driver rotates the mount about a rotation axis. The spool is coupled to the tether, and defines a spool axis that is non-coaxial with the rotation axis. The tether extends away from the winch toward the end portion. The spool is fixedly coupled to the mount such that rotation of the mount about the rotation axis draws the end portion of the tether toward the spool by winding the tether around the spool axis of the spool. Other embodiments are also described.
SUTURE TENSION DISTRIBUTION
A tension-distribution device includes a rotationally-symmetric structure and two or more suture-engagement features associated with the rotationally-symmetric structure, the suture-engagement features being configured to receive one or more suture portions therein. The two or more suture-engagement features are evenly spaced rotationally about an axial center of the rotationally-symmetric structure.
DEVICE FOR MENISCAL REPAIR
The present disclosure relates to a device for meniscal repair for use in areas of a human body where tissue can either be surgically reattached to bone or surgically repaired when a tear forms in the tissue. The device may take one of three forms; in a first form, the device comprises a handle and a deployment member permitting the deployment of anchors or sutures to the tissue requiring repair; subsequently the device may take a second form comprising the handle, still in place, and a cutter member for manipulating and cutting anchors and sutures to assist in repair of the tissue; in its third form, the device comprises the handle, still in place, and a fluid injection member for applying a fluid to aid in improving biological conditions for the tissue to heal.
GUIDED ADVANCEMENT OF AN IMPLANT
A tissue-engaging element is advanced to a heart, while coupled to a guide member. The tissue-engaging element is then coupled to tissue of the heart. An elongate implant is subsequently slid distally along the guide member toward the tissue-engaging element, and the elongate implant is subsequently locked to the tissue-engaging element. Other embodiments are also described.
PROSTHETIC MITRAL VALVE AND DELIVERY METHOD
A valve prosthesis and methods for implanting the prosthesis are provided. The prosthesis generally includes a self-expanding frame and two or more engagement arms. A valve prosthesis is sutured to the self-expanding frame. Each engagement arm corresponds to a native mitral valve leaflet. At least one engagement arm immobilizes the native leaflets, and holds the native leaflets close to the main frame. The prosthetic mitral valve frame also includes two or more anchor attachment points. Each anchor attachment point is attached to one or more anchors that help attach the valve prosthesis to the heart.
TECHNIQUES FOR GUIDE-WIRE BASED ADVANCEMENT OF A TOOL
An anchor is shaped to define a helix. A deployment tool is reversibly coupled to the anchor, and includes a lance. The deployment tool is configured to transluminally advance the anchor to the heart, and to stabilize the anchor at the tissue by driving the lance into the tissue. The deployment tool is also configured to anchor the anchor to the tissue, for example, by driving the tissue-penetrating helix into the tissue while the anchor remains stabilized at the tissue by the lance in the tissue, and to subsequently retract the lance from the tissue while leaving the anchor anchored to the tissue. Other embodiments are also described.
ANCHOR MAGAZINES
A catheter device includes a tube, and an extracorporeal unit coupled to a proximal end of the tube. An implant includes a series of anchors and a tether. The series of anchors includes a first anchor and other anchors, arranged along the extracorporeal unit. Each of the anchors includes a tissue-engaging element, and a head that defines an eyelet. The tether extends, along the extracorporeal unit, through the eyelet of each of the other anchors to the first anchor such that (i) the first anchor is advanceable, with a distal end of the tether, distally into and through the tube toward the tissue, and (ii) subsequently, the other anchors are slidable, sequentially, over and along the tether, distally into and through the tube toward the first anchor. Other applications are also described.
KNOTLESS ANCHOR TEMPORARY SUTURE CAPTURE
Various exemplary devices, systems, and methods for knotless anchor temporary suture capture are provided. In general, an inserter tool is configured for knotless anchor insertion in a soft tissue repair surgical procedure. The inserter tool is configured to insert an anchor into a bone of a patient to secure a soft tissue relative to the bone. A suture coupled to the soft tissue is secured relative to the bone by being trapped between an exterior surface of the anchor and a bone surface defining a hole in the bone in which the anchor is positioned. The inserter tool and the anchor are configured to cooperate with one another to temporarily capture and lock the suture with respect to the anchor and the inserter tool before the anchor is secured in the bone hole.
