Described herein are systems and methods for extracting a broken fragment of a dental abutment screw from a dental implant. One such system includes an extractor tool having a tubular outer body and a conductor positioned within the tubular outer body, and an applicator that receives and end of the extractor tool and also includes a heating element that converts electrical energy into heat that is conducted to the extractor tool to melt a thermoplastic adhesive in a cavity at the distal end of the extractor tool, such that the melted thermoplastic adhesive can conform to and engage with a broken fragment of a dental abutment screw within a dental implant when the adhesive cools. The extractor tool can then be rotated to unscrew the broken fragment from the dental implant.

A new implant for bone fracture treatment that can easily and securely fix bone fragments is provided. An implant 2 for bone fracture treatment that covers bone fragments gathered at a site to be treated for a bone fracture in a living body and reduces and fixes the site invasively includes a metal knit portion 10 formed by knitting a metal string 11 constituted by one or a plurality of biocompatible metal string elements 12 into a cylindrical shape by circular knitting. The implant 2 further includes a resin knit portion 30 formed by knitting a resin string 31 constituted by one or a plurality of biocompatible resin string elements into a cylindrical shape by circular knitting. The metal knit portion 10 and the resin knit portion 30 are knitted to be continuous in an axial direction.

Disclosed is a fenestrated bone anchor suitable for being anchored in live bone tissue of a human or animal patient. The bone anchor comprises a shaft with a proximal end and a distal end and a circumferential surface extending from the proximal end to the distal end. The shaft further comprises a longitudinal cavity extending from the proximal end towards the distal end and a plurality of lateral channels extending through a wall of the shaft from the axial cavity to the circumferential surface. The lateral channel has a pear-shaped cross section and/or the thickness of the wall increases gradually in selected ones of directions towards the lateral channels. The fenestrated bone anchor is e.g. a component of a surgical system comprising an interbody fusion device of the stand-alone type.

A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

A dynamic stabilization assembly includes a core, typically in the form of a tensioned cord, at least one pair of bone anchors, a spacer surrounding the core located between the bone anchors, at least one elastic bumper and at least one fixing or blocking member. The core is slidable with respect to at least one of the bone anchors, the spacer and the bumper. The bumper is compressed. Bone screws of the assembly include closure structures that lock against the bone screw independent of any fixing or sliding of the core with respect to the bone screw.

Staple cartridge assemblies for use with surgical stapling instruments and methods for manufacturing the same are provided. Scaffolds for use with a surgical staple cartridge and methods for manufacturing the same are also provided.

A joint stabilization (reduction) system and associated methods and tools for placement of the system in an open or minimally invasive technique. The joint stabilization system includes a flexible prosthetic band for stabilizing the bones in proper position and a connector mechanism for joining the two ends of the prosthetic band around the bones. One end of the prosthetic band can be permanently attached to the connector.

This disclosure relates to a medical device. The medical device comprises a first and a second component. The first component comprises a first portion having a first handle part and a second portion having a grip. The second component is linked to the first component and is configured to be in communication with the first component to be actuated from an open to a closed position. The second component defines a third portion and a fourth portion, the third portion defining a second handle part and the fourth portion defining a second grip that is configured to grip a tissue in combination with the first grip portion of the first component. In certain embodiments, the first component or second component comprises a substantially straight member attached distally from the grip.

A suture anchor retaining a suture is fixated in hard tissue, in particular in bone tissue, using any per se known method and is then secured using a securing element including a material having thermoplastic properties, which is liquefied in situ and made to penetrate the hard tissue in which the suture anchor is fixated. The securing element is e.g. a thermoplastic plug or thermoplastic sleeve which is anchored above the suture anchor in a mouth area of the same hard tissue opening. Alternatively the securing element is a thermoplastic pin which is introduced into an inner cavity of the suture anchor, wherein the material having thermoplastic properties is liquefied in this cavity and, in a liquid state is pressed through passages connecting the cavity with outer surfaces of the anchor.

One aspect relates to a bone cement applicator having a cartridge with an interior, a cartridge head with a delivery opening, a mixing member which is movable in the interior with a mixing rod. A delivery plunger is arranged in the cartridge and is mounted in the interior and is pressable in the direction of the delivery opening. The delivery plunger rests with an outer cylindrical circumferential surface against an inner wall of the cartridge. A clamping element is arranged on the inner wall of the cartridge in the region of a back side of the interior. The clamping element projects out of the inner wall of the cartridge. The cylindrical circumferential surface of the delivery plunger is resiliently deformable by the clamping element in the direction of a central cylinder axis, such that the delivery plunger is clampable in place with the at least one clamping element on the back side of the cartridge.
