Abstract:
The present disclosure relates to an interference screw having a body with a proximal end, distal end, and longitudinal axis extending between thereinbetween. The screw further includes threads for fixing the screw into bone. The screw further includes a through bore defined by the body. The through bore extends between the proximal and distal ends along the longitudinal axis, and has a surface. The screw further includes a controlling member formed by the through bore surface. To install the screw into bone, a surgeon turns the screw with a driver that engages with the controlling member. The driver only engages the controlling member when it is in a driving orientation with respect to the controlling member. Advantageously, with this “one-way” engagement the surgeon can control and confirm the orientation of the driver without seeing the driver and/or screw.
Abstract:
The present invention provides suture retention devices for retaining a suture on a bodily wall, e.g. for affixing the suture to the skin such as during the creation of an external percutaneous fluidic connection. In one embodiment, a device includes a base member and a swivel member. In another embodiment, the device includes a base member, first and second jaws, and a key. Operation of the swivel member or key serves to lock the suture to the device, and hence maintain tension on the suture while affixed to the skin.
Abstract:
A suture anchor is described. The suture anchor includes an elongate anchor body having a proximal end and a distal end, at least one suture secured within the anchor body, and at least one piercing structure secured within the body extending proximally out of the proximal end of the body, wherein the at least one piercing structure is engaged with the at least one suture. A method of attaching soft tissue to bone in a subject is also described. The method includes the steps of securing an anchor device into a bore formed in the bone, the anchor device comprising an anchor body and at least one pre-loaded piercing structure with at least one suture attached to both the anchor body and the piercing structure, piercing a soft tissue by forcing the at least one piercing structure through the soft tissue, such that at least a portion of the at least one suture passes through the soft tissue, and tying the at least one suture against the soft tissue to secure the soft tissue to the bone.
Abstract:
Examples of the invention include implants, instruments, and methods for surgical transosseous attachment to a bone. More particularly, examples of the invention relate to knotless suture anchors.
Abstract:
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 relate to multi-anchor constructs formed by. a. affixing at least one suture to the bone medial to the lateral edge of the soft tissue using a first implant, such as a cannulated knotless suture anchor, such that no portion of the implant lies lateral to the soft tissue edge; b. passing a first length of suture from the first implant over the soft tissue; c. forming a socket lateral to the edge of the soft tissue such that it is not underneath the soft tissue; d. establishing a desired tension in the first length of suture; and e. placing the implant in the socket so as to trap a portion of the first length of suture between at least a first portion of the implant and the wall of the socket so as to provide fixation. Multi-anchor constructs of the present invention may employ threaded implants exclusively, push-in implants exclusively, or a combination of threaded and push-in implants.
Abstract:
A suture anchor includes a threaded anchor body having a first central bore in communication with a second central bore. The suture anchor includes an internal eyelet formed of a loop disposed at least partially inside the first central bore. The ends extending from the loop are tied together to form at least one knot which is housed in the second central bore provided at the distal end of the anchor body. The knot increases the pullout strength of the suture even in soft bone, provides increased suture fixation, and eliminates the anchor “pull back.”
Abstract:
Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with splices and loops having attached flexible materials that are pre-loaded onto modified knotless anchors (for example, swivel and/or screw-in suture anchors and/or push-in suture anchors with a distal eyelet) to position the self-locking, adjustable construct at the repair site. The systems allow for knotless tensioning of the tissue after the knotless anchors have been implanted.
Abstract:
Disclosed herein are exemplary embodiments of suture securement devices that replace the need to tie knots in sutures. Some embodiments comprise an annular outer body and one or more suture engagement tabs extending inwardly from the outer body. The devices can comprise a superelastic and/or shape-memory material and have a generally in-plane initial configuration. The suture engagement portions are deformable out-of-plane to an active configuration with the outer body compressed and the tabs interlocked with each other. The device can be heat-set in the deformed configuration. The interlocked tabs exert a pinching force on sutures passing between them that restricts the sutures from sliding through the opening in one longitudinal direction.
Abstract:
A method and apparatus for surgically repairing a tear in soft tissue is disclosed. A plurality of collapsible tubes are positioned about the suture. The collapsible tubes are pushed through soft tissue and orthopedic mesh on opposite sides of a tear in soft tissue. When tension is applied to the suture, the tubes are compressed to fix the suture to the soft tissue and draw the soft tissue portions together.
Abstract:
A method for securing a strand to a fixation member for arthroscopic fixation, wherein the fixation member includes a channel on an exterior surface and an aperture therethrough. The method includes passing a strand having first and second ends through a flexible sleeve, passing the sleeve through the aperture of the fixation member in a first direction, tensioning the strand, and pulling the sleeve in a second direction different than the first direction to secure the sleeve to the fixation member without tying the strand on the fixation member.
