Securing graft tissue in a bone tunnel and implementations thereof
This disclosure describes embodiments of an anchor with a body configured to expand radially outwardly along its entire length. The anchor includes, but is not limited to, an elongate body having a distal end, a proximal end, and a longitudinal axis extending therebetween, the elongate body having an outer surface and an inner surface, the inner surface defining a bore aligned with and extending along the longitudinal axis, the elongate body comprising a slot penetrating into the outer surface towards the longitudinal axis, the slot forming a path circumscribing the longitudinal axis.
MULTI-SUTURE KNOTLESS ANCHOR FOR ATTACHING TISSUE TO BONE AND RELATED METHOD
A multi-suture knotless anchor and related method for securing soft tissue, such as tendons, to bone are described. The suture anchor includes a body, a sleeve, and an outer deformable bone locking structure. The bone locking structure has a first low profile configuration for insertion into the bone, and a second larger profile configuration for engaging the bone when actuated. The bone anchor and methods permit a suture attachment that lies beneath the cortical bone surface and does not require tying of knots in the suture.
Distal tip two piece external expansion anchor
Examples of a suture anchor (100) having a non-expandable body (105) and expendable cap (110) are described herein. In response to an axial insertion force that brings the non-expandable body and expendable cap together inside a bone hole, the expendable cap expands radially. This creates a radial force of expansion that advantageously augments an interference fit between the suture anchor and bone hole, which leads to higher fixation strength. Other examples include retention features that inhibit the expendable cap from returning back into its unexpanded state. This advantageously maintains the radial force of expansion against the surrounding pressure of the walls of the bone hole pressing back on the suture.
DEVICES AND METHODS FOR OCCLUDING OR PROMOTING FLUID FLOW
Devices and methods for occluding or promoting fluid flow through openings are disclosed. In one exemplary embodiment an occlusion device is provided having an expandable outer elongate tubular body, a guide member extending from a distal end of the outer body, and a slide tube disposed within the outer body, the proximal portions of the outer body and the slide tube being fixedly mated. The slide tube is configured to slide distally within the outer tubular body when the tubular body is expanded to form wings. A tether can be included as part of the device and it can be used to assist in positioning and locking a location of the device in an opening. Exemplary methods for delivering devices disclosed herein are also provided.
METHOD AND APPARATUS FOR RE-ATTACHING THE LABRUM TO THE ACETABULUM, INCLUDING THE PROVISION AND USE OF A NOVEL SUTURE ANCHOR SYSTEM
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.
Soft suture anchor assembly with barbed suture and attached tissue fixation disk
A suture anchor assembly and a method of tissue repair using the assembly. The assembly includes a soft suture anchor formed of a flexible tubular sheath with opposing open ends which receives a suture strand from a suture construct. The suture strand has a tensioning free end and an opposite tissue-fixation end. A tissue-fixation device, such as a disk, is coupled to the tissue-fixation end of the suture strand. The suture strand has uni-directional barbs which allow one-way tensioning, to provide secure fixation of soft tissue to bone as the strand is pulled through the sheath of the soft anchor.
Bioabsorbable Deformable Anchors
Biodegradable and bioabsorbable anchors and anchor systems for use in musculoskeletal fixation applications comprising (1) an anchor body comprising a longitudinal axis, a proximal end, a distal end, an outer surface, and a bore extending from the proximal end and parallel to the longitudinal axis, wherein the bore defines an inner surface of the anchor body, and wherein at least a portion of the anchor body is expandable in a direction non-parallel to the longitudinal axis, and (2) an expansion pin comprising a longitudinal axis, a proximal end, a distal end, and a surface, and configured for insertion into the bore such that, when inserted, it expands the expandable portion of the anchor body in a direction non-parallel to the longitudinal axis. Both the disclosed anchors and anchor systems are at least in part formed from a citrate-based polymer.
Methods and apparatus for implanting prostheses
A deployment device for a tissue repair system includes a front delivery assembly that is detachable from a base assembly of the deployment device. The front delivery assembly includes at least one prosthesis and at least one driven assembly that actuates the at least one prosthesis. The base assembly includes a driving assembly that may engage the at least one driven assembly of the at least one prosthesis. The front delivery assembly can be rotated so that the position of a prosthesis in the front delivery assembly is moved in and out of alignment with the driving assembly. A kit of parts may be provided that includes a base assembly as well as two or more detachable front delivery assemblies.
Fixation Member With Separate Eyelet And Methods Of Use Thereof
In one embodiment of the present disclosure, an implant system for securing tissue to bone, including a first fixation member releasably engaged to a first inserter, the first fixation member having a throughbore adapted to accept a filament therethrough and a cannulation extending from a proximal end of the first fixation member to a distal end of the first fixation member, the first inserter positioned through the cannulation and having a distal tip extending distally beyond the distal end of the first fixation member, and a second fixation member releasably engaged to a second inserter different from the first inserter, the second fixation member having a size capable of being positioned within the bonehole.
OVERDRIVE PREVENTION FOR EXPANDABLE ANCHOR
Surgical devices and methods are provided for anchoring tissue to bone, and more particularly methods and devices are provided for preventing over-insertion of an expander into a sheath of a two-piece anchor. For example, a tendon anchoring system is provided with an anchor assembly and an inserter tool. The anchor assembly includes a sheath with a threaded lumen and a threaded expander screw configured to be threadably disposed within the sheath to cause the sheath to expand outward. The inserter tool includes an elongate outer shaft with a distal end configured to couple to a proximal end of the sheath, and an elongate inner shaft with a distal drive tip configured to engage a proximal end of the expander screw. In one embodiment, the inner shaft can be rotatable relative to the outer shaft to thread the expander screw into the sheath, and the inner shaft can be prevented from rotating relative to the outer shaft when the expander screw is fully threaded into the sheath to prevent over-insertion of the expander screw into the sheath.
