Anchors and methods for securing suture to bone
11612387 · 2023-03-28 · ·

A method for securing suture to bone comprises drilling a hole in a desired portion of bone at a desired procedural site, passing a strand of suture through a portion of soft tissue to be approximated to the portion of bone, and extending the free suture ends proximally from the soft tissue. The suture is loaded into an anchor implant. Using an inserter, on a distal end of which is attached the anchor implant, the anchor implant is manipulated into the bone hole. The suture is then tensioned to a desired level by pulling on the free suture ends, after the anchor implant is positioned in the bone hole. The free suture ends are wrapped about a suture cleat on an inserter handle once the desired tension level is achieved. A proximal anchor component is moved distally to engage with a distal anchor component to lock the anchor in place within the bone hole, and to lock the suture in place within the anchor. Then, the inserter is removed from the procedural site.

Disclosed are devices, methods and/or systems for securing tissue to bone, including a suture anchor implant having a body with an internal cavity and one or more helical cutting flutes positioned on an external surface of the body which direct at least a portion of the cut bony material into the internal cavity as the body is rotated into bone.

Suture-locking washer for use with a bone anchor, and method for supporting the thumb of a patient after basal joint arthroplasty, and other novel orthopedic apparatus and other novel orthopedic procedures

The invention provides surgical methods, devices, apparatus, and systems for supporting the thumb of a patient after basal joint arthroplasty. The embodiments of the invention comprise at least one index metacarpal anchor, at least one thumb metacarpal anchor, at least one sling for positioning the thumb metacarpal anchor relative to the index metacarpal anchor, and at least one anchor washer for tightening and securing the sling(s) without the need to tie the suture(s) components of the sling(s) into knots. Index and thumb metacarpal anchors comprise at least one bone-engaging element for engaging the respective metacarpal. The anchor washer may incorporate one or more sling-engagement mechanisms. Increasing the number of sling-engagement mechanisms associated with the anchor washer increases the surface area of the sling(s) and provides multiple sling elements to provide redundancy and increase the pull force of the sling(s) attachment(s) used to affix the thumb and index metacarpal anchors into a position relative to each other.

CLEATING SYSTEM FOR A MEDICAL CANNULA
20220338860 · 2022-10-27 · ·

A suture cleating system for arthroscopic or endoscopic cannula to facilitate suture management while preserving seal functionality. The suture cleating system includes an end cap with an aperture extending therethrough and one or more cleats extending therefrom. A cannula body extends distally from the end cap. A seal is connected between the cannula body and the end cap. The seal has a seal slit extending therethrough and the seal slit is substantially aligned with the aperture of the end cap. In use, a suture extends through the cannula, the seal slit, and the aperture in the end cap. The suture can be tensioned from the aperture in the end cap and secured in a suture slot between two cleats.

KNOTLESS SUTURE ANCHORS

Methods and systems are provided for securing tissue to bone. A suture anchor system can include a cannulated suture anchor having at least one driven feature disposed in a lumen and a bone-engaging feature disposed on an external surface. A cannulated inserter member can have an elongate member with a lumen and can be disposed within the lumen of the anchor. The elongate member can have a drive feature that can engage the driven feature. The inner tube can be disposed within the lumen of the inserter member. The inner tube can have a lumen and a length greater than the anchor such that the inner tube extends distally beyond the anchor. A distal swivel member can have a lumen and a distal end having a suture separating feature. The distal swivel member can be mounted adjacent to the anchor and can be rotatable relative to the anchor.

KNOTLESS SUTURE ANCHOR SYSTEM WITH SUTURE MANAGEMENT STRUCTURE

Methods and systems are provided for securing tissue to bone. A suture anchor system can include an inserter tool having a lumen and an inserter shaft with an anchor receiving portion that is proximal to a distal extension. The anchor receiving portion can have a drive feature and the distal extension can have a diameter less than the anchor receiving portion. An anchor can be disposed on the anchor receiving portion of the inserter tool, and can have a driven feature disposed in a lumen configured to engage the drive member of the anchor receiving portion and a bone-engaging feature disposed on an external surface. A suture seating member can be removably disposed on the distal extension, can be rotatable independent of the anchor, and can have a lumen with an opening on a distal end, where the distal end of the suture seating member has a suture seating surface.

KNOTLESS SUTURE ANCHORS

Methods and systems are provided for securing tissue to bone. A suture anchor can include an elongate body having a proximal end and a distal end and an external surface with a plurality of longitudinally spaced bone-engaging features formed at least partially circumferentially thereon over at least a portion of a length of the suture anchor. The proximal end can have a lumen extending at least partially into the elongate body and the distal end can have a suture engaging feature proximate thereto. A first series of bone-engaging features can have a dimension that increases from a distal to a proximal end of each bone-engaging feature of the first series of bone-engaging features. A second series of bone-engaging features can have a dimension that decreases from a distal to a proximal end of each bone-engaging feature of the second series of bone-engaging features.

System and method for repairing articular surfaces

A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.

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.
