An implant to be fastened to a tissue, a tool a kit and a method. The implant has a first end, a second end and an elongated shank made in part from a first polymer material. The implant includes a contact surface for receiving external mechanical energy for deforming the shape of the implant such that the shape of the implant can be deformed and locked in the tissue by the effect of the external mechanical energy.

Implant, implantation tool, kit and method

A novel polymer composition is provided which includes a base material including a biodegradable polymer or copolymer, and a copolymer additive including one or more monomers imparting a tensile strength to the polymer composition at room temperature that is lower than a tensile strength at room temperature for the base material.

Resorbable polymer compositions

A one-piece suture anchor for anchoring a suture into a bone comprising an elongated body having proximal and distal ends, the body comprising at least one channel for receiving a suture, the channel comprising two elongated longitudinal guides continuing from the proximal end of the suture anchor towards the distal end of the anchor suture, wherein the guides are connected to each other by a section of channel that is configured such that it is not bent at any given point at an angle greater than or equal to ninety degrees.

Suture anchor

A fixation implant generally includes at least one shaft configured to securely fit into a hole formed in bone. The shaft is of sufficient length relative to the interior diameter of the hole and, in some preferred embodiments, has locking protuberances, like threads, ridges, or barbs, that resist removal of the shaft from the hole in the bone when different types of forces, such as tensile or bending forces, are applied to the implant. The shaft is generally cylindrical in shape, however, in various embodiments, different cross-sections could be used. In a preferred embodiment the implant has a flattened and bent end portion emerging from only one side of the shaft. At the other side of the implant the outer surface of the shaft and the emerging end portion form a smooth surface, without any projections. This smooth surface at the end of the implant prevents irritation of the surrounding tissue. The end portion has a mating surface configured to grip a portion of the soft tissue surrounding the hole between the bone and the mating surface. The longitudinal axis of the shaft is oriented at an angle of less than 90 degrees relative to the mating surface. In this fashion, the implant anchors soft tissue, such as rotator cuff tissue, to bone.

Anatomical fixation implant

A bioabsorbable surgical implant for use in supporting soft tissue in a superior position in the body is described. The surgical implant includes a shaft that connects the implant to a bone or hard tissue and a head secured to the shaft. The head of the implant has a concave lower surface so that a suture (or sutures) can easily be wound around the shaft below the head and locked to this position by tightening the head against bone or hard tissue and by pushing or turning the shaft into the bone or hard tissue. The connected shaft and head are formed from a resorbable polymer, copolymer, polymer alloy or composite, which maintains a specified strength for a period of time at least equal to a healing period for the patient. Thereafter, the surgical implant is substantially resorbed by the body over a period of time needed for healing. The surgical implant is particularly adapted for use in endoscopic face and/or brow lift surgery and other endoscopic cosmetic, plastic and reconstructive surgical procedures, where sutures are applied for tissue lifting.
