20200138577 · 2020-05-07 ·

There is provided herein a supra mitral device for mitral/tricuspid valve repair in a subject in need thereof, the device comprising: a main body portion having essentially annular D-shape with an eccentric opening, such that a posterior section of said main body portion is wider than an anterior section of said main body portion, said posterior section of said main body portion configured for coverage and attachment to essentially the whole section of the posterior leaflet of the mitral valve which faces the left atrium on systole, thereby preventing and/or reducing mitral regurgitation, wherein said posterior section of said main body portion is made of a pliable material, adapted to stiffen after implantation of the device.

Biceps Tenodesis Implants and Delivery Tools

Methods and devices are provided for anchoring a ligament or tendon to bone. In one embodiment, a surgical implant is provided having a sheath and an expander that is received within the sheath. Various delivery tools, including a sheath inserter and a driver, are also provided. In use, the sheath inserter can be used to position a tendon within a prepared bone hole, and it can be used to deliver the sheath with a guidewire coupled thereto into the bone hole. The driver can be provided for delivering the expander into the sheath. A loader can optionally be used to load the driver and expander onto the guidewire coupled to the implanted sheath.

Treating dysfunctional cardiac tissue

Medical devices, systems, and methods reduce the distance between two points in tissue, often for treatment of congestive heart failure and often in a minimally invasive manner. An anchor is inserted along an insertion path through a first wall of the heart. An arm of the anchor is deployed and rotationally positioned according to a desired alignment. Application of tension to the anchor may draw the first and second walls of the heart into contact along a desired contour so as to effect a desired change in the geometry of the heart. Additional anchors may be inserted and aligned with the first anchor to close off a portion of a ventricle such that the ventricle is geometrically remodeled and disease progression is reversed, halted, and/or slowed.

System and method for attaching soft tissue to bone

Methods and devices for securing soft tissue to a rigid material such as bone are disclosed herein. A bone anchor is described that comprises a base and a top such that suture material may be compressed between surfaces on the base and top to secure the suture to the anchor. Also described is an inserter that can be used to insert the bone anchor into bone and move the anchor top relative to the anchor base to clamp suture material there between. Also described is a soft-tissue and bone piercing anchor and associated inserter. Methods are described that allow use of the bone anchors to provide multiple lengths of suture material to compress a large area of soft tissue against bone.

SURGICAL ARTICLES AND METHODS

Described are devices, implants, kits, and related methods for treating pelvic conditions such as urinary in incontinence, in a male or a female patient. The invention includes, in one embodiment, a multi-piece implant, including a tissue support piece, extension portion, and one or more self-fixating tips. The device may be employed through a medial incision in the pelvic region of the patient.

Method for knotless fixation of tissue

A suture anchor for knotless fixation of tissue. A swivel suture anchor has an anchor tip for receiving a suture strand, for surgical tissue repair without requiring suture knots. Tension on the repair constructs is adjustable. The swivel anchor is secured in a hole in bone by advancing a fixation device, such as a cannulated interference screw, over the body of the anchor.

SYSTEM AND METHOD FOR SECURING TISSUE TO BONE

Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A tissue capture anchor is described that includes an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and spreader and inside surfaces of a bone hole to secure the tissue within the hole. A bone anchor is described that includes an anchor body with expandable tines and a spreader that expands the tines into bone. The spreader captures tissue via a suture loop at the distal end of the bone anchor. Also described is an inserter that can be used to insert the anchor into bone and move the spreader within the anchor to expand the anchor and capture the tissue between the anchor and the bone. Methods are described that allow the use of bone anchors to secure tissue to bone.

Luminal Structure Anchoring Devices and Methods

The present invention relates to a device for endoscopy or endosonography-guided transluminal interventions whereby two luminal structures in the body may be drawn toward each other and a fluid conduit formed in between. The device may have a hollow central member to which is coupled a distal retention member and in one embodiment a proximal retention member. The retention members may each be positioned inside one of the luminal structures and expanded from a first condition to an expanded second condition having an increased radius. The length of the central member may be shortened and its diameter expanded to approximate the two retention members and thereby the luminal structures.

Percutaneous repair of mitral prolapse

A mitral valve leaflet repair system may include a delivery catheter having at least one lumen extending proximally from a distal end of the delivery catheter, a plurality of anchor elements disposed within the at least one lumen, each of the plurality of anchor elements being configured to extend through one layer of mitral valve leaflet tissue, and a securing element configured to secure at least two of the plurality of anchor elements together on one side of the mitral valve leaflet tissue. The at least one lumen may include a suction lumen configured to grasp a mitral valve leaflet prior to extending the plurality of anchor elements through one layer of mitral valve leaflet tissue.

Mitral valve repair devices

This document provides devices and methods for repairing a prolapsing mitral valve leaflet using minimally invasive catheter based approaches. For example, percutaneous procedures that involve folding and securing a segment of a prolapsing leaflet onto or pulling and securing a segment of a prolapsing leaflet through part of the greater mitral valve leaflet are provided. In some cases, artificial chordae are installed to stabilize and maintain desired orientation of the leaflets.
