A tissue fixation system including a delivery tube and an elongated fastener with a loop at a proximal end and a distal end. A proximal end of an elongated curved needle is attached to the delivery tube. A distal end of the needle is configured to penetrate tissue. The needle includes an open channel sized to receive the elongated fastener with the loop located near the proximal end of the elongated curved needle and the distal end of the elongated fastener located near the distal end of the elongated curved needle. A capture needle is slidably positioned in the delivery tube to slide through the loop in the proximal end of the elongated fastener. The capture needle is configured to grasp the distal end of the elongated fastener and pull the distal end of the elongated fastener through the loop to cinch the elongated fastener.

A suturing device includes an elongated body having an outer wall defining an interior space of the body, a shaft located in the interior space, and a needle mounted on a distal end of the shaft. The needle has a distal section transverse to a longitudinal axis of the shaft. The distal section of the needle terminates in a first jaw and a second jaw forming a forceps defining a piercing tip. The first jaw and second jaw have a grasping position wherein the first jaw and second jaw grasp a suturing material, and a release position wherein the first jaw and second jaw release the suturing material. After grasping the suturing material with the needle, the shaft rotates the needle to advance the needle and suturing material through tissue and mesh placed on the tissue. Spaced apart portions of the suturing material are then fused to create a suture.

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.

A three-dimensional thread making method using ultrasonic waves is provided. The method includes inserting a yarn into a position corresponding to an engraved pattern of a mold base between an ultrasonic wave generator and the mold base at positions adjacent to each other, applying ultrasonic waves to the yarn while the ultrasonic wave generator pressurizes the yarn, and injecting a medical anti-loosening member made in a form of the engraved pattern due to the ultrasonic waves. The medical anti-loosening member includes a medical three-dimensional thread formed to have a plurality of protrusions facing each other on both sides and a medical anti-loosening screw.

An implantable device for aiding in generating connective tissue between a pair of anatomical structures in a mammalian body is provided. The device includes an elongate, flexible tether which can be secured between the anatomical structures and which carries a scaffold which is generally porous so as to be capable of promoting tissue ingrowth and collagen deposition along its length. The scaffold extends along the tether for a sufficient distance so that it is securable in at least close proximity to an anatomical structure at either end. The pores in the scaffold extend through the scaffold and each has a diameter in the range of about 10 m to about 200 m. The length of the tether is selected to be a desirable maximum distance between the anatomical structures along a desired path when secured therebetween.

Polymeric fibers, and apparatuses for and methods of processing such fibers to be useful as sutures, where at least one end of a fiber includes a termination feature. The termination feature is formed through the application of energy to a coiled region of the fiber.

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.

A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.
