TISSUE ANCHORING DEVICE AND USE THEREOF

A tissue anchor for use in holding a tissue to a bone is provided. The anchor includes a distal tip, a proximal end, and an elongated body extending from the distal tip to the proximal end along a longitudinal axis. The elongated body can include a cannulated tunnel having an opening at the proximal end. An engagement member can be disposed inside of the elongated body and configured to enable the loading of a first thread-like fixation element through the cannulated tunnel. The distal tip of the tissue anchor can include an opening dimensioned and configured to capture and retain a second thread-like fixation element.

POINT-LOADING KNOTLESS FIXATION DEVICES

Surgical constructs and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair constructs include a fixation device, a flexible strand, and a shuttle/pull device attached to the flexible strand and provided within the body of the fixation device. A splice is formed by pulling on the shuttle/pull device to allow desired tensioning of soft tissue to be fixated or repaired relative to the bone.

Knotless suture anchor and deployment device
11490884 · 2022-11-08 · ·

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.

Medical implant and method for heart valve repair

A sutureless implant for replacing damaged natural chordae tendineae of a human or possibly animal heart, the implant including a distal implant part, a proximal implant part, and an artificial chord. The distal implant part is configured to fit in a lumen of an implant delivery device and includes a self-spreading portion spreading radially outside when the distal implant part is released from the lumen, the self-spreading portion being capable of anchoring the distal implant part in human muscle tissue. The proximal implant part is configured to fit in the lumen of the implant delivery device and comprises a self-spreading portion spreading radially outside when the proximal implant part is released from the lumen, the self-spreading portion being capable of bearing on a tissue portion of leaflet tissue. The distal implant part and the proximal implant part are connected by the chord.

METHOD AND APPARATUS FOR REATTACHING THE LABRUM TO THE ACETABULUM, INCLUDING THE PROVISION AND USE OF A NOVEL SUTURE ANCHOR SYSTEM
20230099495 · 2023-03-30 ·

Apparatus for securing an object to bone, the apparatus comprising: an anchor assembly comprising an anchor and an actuation element extending from the anchor, wherein applying a force to the actuation element when the anchor is disposed in a hole formed in a bone secures the anchor to the bone; and an inserter for deploying the anchor assembly in a hole formed in a bone, the inserter comprising: a shaft for releasably engaging the anchor; and a force delivery mechanism mounted to the shaft and connected to the actuation element, the force delivery mechanism being constructed so as to receive an input force from an external source and to selectively apply an output force to the actuation element, with the force delivery mechanism being constructed so that the magnitude of the output force is limited regardless of the magnitude of the input force.

KNOTLESS SUTURE ANCHOR

A suture anchor comprises a tubular body having an axial bore therethrough and having one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole, such as threads. A lateral port passes through the body from the bore to the exterior surface and is formed of a slot entering the body from its proximal end. A length of suture for attaching soft tissue to bone passes down along the exterior surface over the one or more purchase enhancements, over a distal end of the body, up into the bore through and then back out of the bore and up along the exterior surface over the one or more purchase enhancements.

METHOD FOR COUPLING SOFT TISSUE TO A BONE
20230084732 · 2023-03-16 ·

A method for coupling tissue with a flexible member including a tail and a self-locking construct coupled to the tail. The self-locking construct includes an adjustable first loop and an adjustable second loop coupled thereto. The method includes implanting an anchor in bone, the anchor slidably mounted to the tail. The tail is positioned relative to the tissue. An end of the tail is inserted through the first loop. The tail is passed through the first loop, the second loop is pulled into the anchor, and the self-locking construct is positioned relative to the tissue. The self-locking construct is tightened against the tissue by pulling on an end of the self-locking construct. The first loop is tightened onto the second loop.

ONE-HANDED AND DOUBLE ROW METHODS FOR TISSUE FIXATION

Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture. Particularly preferred embodiments allow for the one-handed operation, namely embodiments in which relative axial movement between the inner tensioning device and outer driver device is optionally physically constrained, for example by means of cooperating and/or compressive elements disposed in the respective hub and handle portions, are described herein. Other preferred embodiments of the present invention relate to multi-anchor constructs that may employ threaded implants exclusively, push-in implants exclusively, or a combination of threaded and push-in implants.

Devices, systems and methods for treating benign prostatic hyperplasia and other conditions

Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures.
