CHORDA REPLACEMENT APPARATUS AND METHOD
Apparatus for coupling a prosthetic chorda to an atrioventricular valve leaflet, the apparatus comprising: a neochorda delivery system comprising a steerable and pushable catheter housing a neochorda attached to a neochorda puncture needle, the catheter operable to push the puncture needle to puncture and thread the neochorda through a papillary muscle of a ventricle; a retriever system comprising a catheter housing a grabber operable to capture the neochorda puncture needle after being threaded through the papillary muscle and withdraw the neochorda puncture needle and neochorda from the ventricle; and a tissue clamping system comprising a catheter housing distal and proximal tissue clamps deployable to clamp a region of an atrioventricular valve between them and hold the region so that it may be punctured by the puncture needle to deliver the neochorda through the leaflet and to the papillary muscle.
SURGICAL TOOL AND METHOD OF USE
A surgical tool incorporates a suture guide with an anchor driver supporting an anchor where the anchor is maintained at a distance from the suture guide until release of a detent mechanism. Thereafter, the anchor is allowed to move into proximity to the suture guide, fixing a suture supported by the suture guide to a substrate, the entire procedure being achievable with a single hand.
Devices, systems, and methods for repairing soft tissue and attaching soft tissue to bone
Devices, systems and/or methods for repairing soft tissue adjacent a soft tissue repair site. In one embodiment, a repair device includes an anchor member, a capture member and one or more flexible members. The anchor member includes a base with at least four legs extending integrally from the base, the at least four legs configured to be moveable from a straight first position to a formed second position. The capture member is configured to be coupled to the anchor member such that the at least four legs of the anchor member move around structural portions of the capture member with the at least four legs of the anchor member in the formed second position. The one or more flexible members are coupled to the base of the anchor member, the one or more flexible members extending at least partially along the base of the anchor member.
Knotless self-locking anchor constructs and methods of tissue fixation
Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with a fixation device, a flexible coupler and an optional shuttle/pull device attached to the flexible strand. An accordion-style weave region is formed by pulling on the shuttle/pull device subsequent to the fixation device being secured into the bone, to allow desired tensioning of soft tissue to be fixated or repaired relative to the bone and secured self-locking of the construct.
LOCKING SUTURE CONSTRUCT
A locking suture construct having suture material with a first end and a second end, each attached to a first body in a slidable manner, a constricting member formed in the second end of the suture material, and a bight in the suture material between the first end and the second end. The bight can be pulled through the constricting member around a second body to create a locking loop. The first end and the second end are passed through the locking loop. Pulling the first end increases a perimeter of the locking loop and moves the constricting member toward the second body. When the constricting member reaches the second body, pulling the first end reduces the perimeter of the locking loop and moves/rotates the constricting member around the second body toward the first body to hold the first body in relative position to the second body.
SUTURE ANCHOR
The present application relates to the field of medical devices, and in particular to a suture anchor. A suture anchor includes an anchor head and an anchor body, wherein a threading hole is formed on the anchor head, the anchor body includes a side pressing portion integrally formed by a plurality of layers of round tables, and at least two opposite longitudinal cuts are formed on each round table of the side pressing portion; from a direction close to the anchor head to a direction away from the anchor head, positions of the longitudinal cuts on adjacent round tables are deflected toward a same side.
Implant with Hole Having Porous Structure For Soft Tissue Fixation
Disclosed herein are an implant with an attachment feature and a method for attaching to the same. The implant may include a cavity with a porous layer disposed within a non-porous layer wherein the non-porous layer defines a chamber. The chamber may receive and confine liquefiable material and direct liquefiable material to permeate through the porous layer. A method of attaching a device to the implant may include liquefying a liquefiable portion of the device and allowing the liquefied material to interdigitate with the second layer and then solidify to prevent pullout.
Knotless suture anchor and deployment device
A deployment device, including a driver shaft; an implant attached to the distal end of the driver shaft; a handle assembly connected to the proximal end of the driver shaft including a handle and a knob positioned distally to the handle; a cleat configured to secure a proximal end of a suture received from the implant through an aperture of the driver shaft resulting in a first applied tension value when the implant is placed in a pilot hole, wherein each of the implant, proximal handle and cleat is connected to the driver shaft such that rotation of the proximal handle in a first direction results in the rotation of the implant in the first direction and the maintenance of at least 50% of the first applied tension value when the implant is rotated in the first direction and advanced in the distal direction within the pilot hole.
Method for knotless fixation of tissue
A swivel suture anchor for knotless fixation of tissue. The suture anchor includes an anchor tip configured to capture suture, the anchor tip being rotatably received within a fixation device upon advancement of the fixation device over a shaft of the anchor tip. The anchor tip is configured to receive a suture to be anchor in bone without requiring suture knots. The anchor tip can be a conical metal tip which is self-punching and avoids the need for pre-drilling a hole in bone. The anchor tip includes a closed aperture to allow free sliding of a suture strand. The suture is secured in a hole in bone by inserting the anchor tip into bone, and advancing a fenestrated fixation device, such as a cannulated interference screw, over a shaft of the anchor tip.
