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 surgical implant made of a polymer, copolymer, polymer mixture or polymer composite that dissolves in the organ system. The manufacturing material is dyed with the coloring agent D&C Violet No. 2 or D&C Green No. 6. Preferably, the amount of the coloring agent is at most approximately 0.03 percent by weight and the implant is sterilized by radiation.

Surgical implant

A fastener for the treatment of fractures and the materials for production thereof. The fastener having a head with a contact portion for an installation tool and an attaching part having a treaded portion. The threads of the threaded portion are 5 to 20 % of the height of the outer diameter of the thread. The material for producing the fastener is a blend containing a biodegradable base material and one or more copolymer additives so that at room temperature the ductility of the blend is substantially higher than that of the pure base material. The base material may be a biodegradable polymer and/or a copolymer.

Bone fracture fastener and material for production thereof

An instrument for shaping a mouth part of a drilled tunnel provided in a bone. The instrument includes a shaft having a longitudinal axis and a first and a second end. The first end of the shaft is provided with a projection, which includes a blade for shaping the mouth part of the drilled tunnel when the instrument is turned around the longitudinal axis of the shaft. The instrument is asymmetric at an intersecting surface perpendicular to the longitudinal axis and intersecting with the blade, the instrument thus shaping the surfaces surrounding the first end only substantially within an area corresponding with a turning angle of such a turning movement.

Instrument

A bone plate for supporting bone. At least one shaping area reducing the shaping resistance of the shape of the bone plate and the bending and/or torsional resistance of the body is arranged in the section of the bone plate between fixation holes.

Bone plate implant

The present invention relates generally to body tissue fixation systems, including body tissue fixation hardware comprising biocompatible, bioabsorbable (resorbable) thermoplastic plates, and methods of using those systems and hardware.

Bioabsorbable, deformable fixation plate

The present invention relates to a surgical fastener or device (implant) formed in the shape of an arrow comprising a shaft with a proximal (first) portion having protrusions and a blunt end and a distal (second) portion having protrusions and a pointed end, the protrusions of the proximal and distal portions configured to lock the implant in a position inside a soft and/or tough tissue according to the use of the implant. The implant may be manufactured of a polymer or a polymeric compound which is substantially (bio)absorbable in tissue conditions and contains oriented reinforcing structure or the like of a polymer or polymeric compound or ceramic bioglass compound. The surgical implant of the invention is particularly but not solely intended to be used in repair surgery of traumas of soft and/or tough tissues containing fibrous structures, such as knee meniscal tissues.

Surgical fastener for tissue treatment

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

The present invention relates to a surgical fastener or device (implant) formed in the shape of an arrow comprising a shaft with a proximal (first) portion having a blunt end and tapered form, such that the proximal portion is broad at its blunt end and tapers in the direction of a distal (second) portion of the shaft, the distal portion having protrusions and a pointed end, wherein the tapered form of the proximal portion and the protrusions of the distal portion are configured to lock the implant in a position inside a soft and/or tough tissue according to the use of the implant. The implant may be manufactured of a polymer or a polymeric compound which is substantially (bio)absorbable (resorable) after implantation in tissue and contains an oriented reinforcing structure or the like of a polymer or polymeric compound or ceramic bioactive glass compound.

Bioabsorbable surgical fastener for tissue treatment

This invention relates to a material that degrades after implantation into a patient's tissue, and resorbs into the patient's body, which material is manufactured of polymer, copolymer or polymer alloy. The material has a non-crystalline, i.e., amorphous structure and is molecularly oriented and reinforced by mechanical deformation. Further, the material can be formed into surgical devices, such as screws and pins, for implantation into a patient.

Under tissue conditions degradable material and a method for its manufacturing

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

The Applicants' invention is a bioactive, biocompatible, bioabsorbable surgical composite that is fabricated bioabsorbable polymers, copolymers or polymer alloys that are self-reinforced and contain ceramic particles or reinforcement fibers, and also can be porous. The composite of the invention can be formed into devices like pins, screws, plates, tacks, bolts, intramedullary nails, suture anchors, staples, and many other devices, all of which are useful in bone-to-bone, soft tissue-to-bone or soft tissue-to-soft tissue fixation or in fixation of bioabsorbable and/or biostable implants in or on bone or soft tissue.

Bioactive, bioabsorbable surgical composite material

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 surgical device made of biodegradable material for keeping open a tissue cavity. The tissue includes at least one tissue type selected from the group consisting of healthy tissue or parts thereof, operated tissues or parts thereof, and damaged tissue or parts thereof. The device includes an elongated rod made of the biodegradable material. The elongated rod is at least partially wound, at least once, around a winding center into a helical configuration in a manner that there exists a space free of material of the biodegradable rod between portions of the elongated rod that are adjacent in the wound structure. The rod is at least partially reinforced with biodegradable reinforcement elements oriented in the longitudinal direction of the elongated rod so as to produce an opening force in the winding due to the effect of the winding of the elongated rod into the helical configuration.
