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.

Anti-penetration bone implant device and method

A device for engagement with a bone includes a dynamically expandable tip (12), a dynamically expandable ring (40), or other dynamically expandable insert (60, 62, 401L) that reacts to forces pushing the implant into bone tissue. The tip (12), ring (40) or insert (60, 62, 401L) expands at least normal to the direction of motion, increasing contact area between the surrounding bone tissue and the material and thereby reducing the occurrence of high areas of contact stress in the adjacent bone tissue. The tip (12), ring (40) or insert (60, 62, 401L) translates forces along an axis of motion into lateral frictional forces that can resist penetration into the bone tissue without the need for additional operator or patient interaction. A method of reducing migration of the device for engagement includes the steps of providing the device and inserting the device within bone tissue.

BONE ANCHOR HAVING DEFORMABLE MEMBERS
20200315605 · 2020-10-08 ·

The provided system includes an inserter, a bone anchor, and one or more sutures. The inserter includes a tube and a plunger within the tube's interior. The bone anchor is structured with multiple deformable members such that it can be transitioned from a compact configuration to an expanded configuration. When inserting the bone anchor, the bone anchor may initially be in a compact configuration within the inserter tube. The inserter tube may be inserted into a bone hole. Then, while the plunger is maintained in its positioned, the tube may be retracted so that the bone anchor is deployed from within the tube. The bone anchor may then be transitioned to an expanded configuration. In some instances, suture tension transitions the bone anchor. In other instances, a pre-set shape of a shape memory material transitions the bone anchor.

Padded transosseous suture

A bone suture assembly including a flexible generally cylindrical sleeve, a plurality of lengths of suture extending through the generally cylindrical sleeve, and at least one sleeve securing thread associated with the generally cylindrical sleeve. A bone suture retaining method including engaging a suture with a bone engaging sleeve, inserting the suture and the bone engaging sleeve engaged thereby into a transosseous tunnel formed into a bone by pulling the bone engaging sleeve into the transosseous tunnel and retaining the suture and the bone engaging sleeve in the transosseous tunnel by virtue of the bone engaging sleeve being unable to fit through an aperture in the bone.

SUTURE DEVICE
20200305860 · 2020-10-01 · ·

The suture device comprises a suture element of elongated shape and intended to be inserted through the flaps of a surgical wound, in which the suture element is made of a shape memory material and has a first pointed extremity adapted to pierce the flaps to allow the passage of the suture element through the latter and their mutual approach to define a suture, and a second extremity opposite the first extremity, and by the fact that the suture element comprises an initial configuration wherein the extremities and the flaps are spaced apart from one another and a final configuration wherein the extremities and the flaps are mutually approached to define the suture.

Method and apparatus for closing a fissure in the annulus of an intervertebral disc, and/or for effecting other anatomical repairs and/or fixations

Apparatus for attaching a suture to an object, the apparatus comprising: an anchor comprising a body having a distal end and a proximal end, and a vertical bore extending through the body substantially perpendicular to the longitudinal axis of the body; wherein the anchor further comprises a recess formed on one side of the body and a U-shaped slot formed on the opposing side of the body, whereby to form a flexible finger extending distally within the body, and further wherein the distal end of the finger is spaced from an opposing portion of the body; and wherein at least one of the flexible finger and the body comprises a cutout extending therethrough, with the cutout cooperating with the U-shaped slot and the recess so as to together form a suture loading hole extending through the body, with the suture loading hole being sized to receive a suture therein.

Crimping instrument with reduced dimension, continued compatibility, and tissue protection features
10772618 · 2020-09-15 · ·

An instrument for crimping a suture fastener to a surgical suture is disclosed. The instrument has a shaft and an expanded receiving face configured to receive the suture fastener and to provide a smoothing radius for a distal end of the shaft. The instrument also has an anvil in the distal end of the shaft. The instrument further has a hammer in the distal end of the shaft and moveable relative to the anvil for crimping the suture fastener therebetween and received in the expanded receiving face. The instrument also has a pusher moveable in a direction substantially parallel to a longitudinal axis of the shaft and configured to engage at least one of the hammer and the anvil for urging the hammer and the anvil together.

Fracture fixation device

Assemblies for securing fractured bone are provided. The assembly includes a first fixation element, a second fixation element, and an adjustable flexible member construct. The first fixation element having a male or a female sleeve is secured within a first portion of the fractured bone. The second fixation element having the other of the male or female sleeve telescopically received within the one of the male or female sleeve is secured within a second portion of the fractured bone. The adjustable flexible member construct extends between the first and second fixation elements and has at least one adjustable loop coupled to the first fixation element and the second fixation element and a pair of adjusting ends extending through an opening in the first fixation element. The pair of adjusting ends can be pulled to reduce a diameter of the adjustable loop and to compress fragments of the fractured bone.

Non-sliding soft anchor
