Patent number: 10856917Abstract: A resorbable implant for osteosynthesis for stiffening in a central joint (e.g., the proximal interphalangeal joint referred to as PIP) during arthrodesis or for stiffening in an end joint (e.g., the distal interphalangeal joint referred to as DIP) during arthrodesis and for osteosynthesis and stabilization of fractures of small bones of the human skeleton includes two shafts placed against each other. At least one fixing aid is located between the shafts. The fixing aid protrudes beyond a diameter of the shafts. Each shaft may have longitudinal grooves and transverse grooves. The implant is a magnesium-based material which can be resorbed by the human body. The disclosed implant has a relatively high tensile strength, excellent stability, optimal healing properties, and an optimally adapted resorption speed.Type: GrantFiled: May 4, 2016Date of Patent: December 8, 2020Assignee: SYNTELLIX AGInventors: Carsten Wingenfeld, Robert Schavan, Jan-Marten Seitz, Arne Lucas

Publication number: 20180140338Abstract: The invention relates to an implant for the osteosynthesis of the PIP arthrodesis or the DIP arthrodesis of small joints and for the osteosynthesis and stabilisation of fractures of small bones of the human skeleton, said implant being resorbable by the human body. The implant consists of two shafts placed against each other. At least one fixing aid is located between the shafts, said fixing aid protruding beyond the diameter of the shaft. Each shaft can optionally have longitudinal grooves and transverse grooves. The implant consists of a magnesium-based material which can be resorbed by the human body. The invention provides an implant which has an extremely high tensile strength, excellent stability, optimal healing properties, and an optimally adapted resorption speed.Type: ApplicationFiled: May 4, 2016Publication date: May 24, 2018Inventors: Carsten WINGENFELD, Robert SCHAVAN, Jan-Marten SEITZ, Arne LUCAS

Patent number: 9402669Abstract: A method for producing a medical implant, such as a bone screw, a bone nail, a bone pin, a plate, a suture anchor, etc. for fastening soft parts, such as tendons, muscles, and ligaments, to a bone, or in the form of an endoprosthesis or at least a part thereof, from a magnesium alloy having a magnesium fraction of at least 80 wt %, in particular of at least 90 wt %, including the following steps: a) melting the magnesium alloy to obtain an alloy melt, b) atomizing the alloy melt under a protective-gas atmosphere and cooling the atomized alloy melt to below the solidification point thereof in order to obtain an alloy powder, c) shaping the alloy powder by pressing to obtain an alloy green body, d) extruding the alloy green body to obtain a magnesium alloy molded part, and e) producing the medical implant from the magnesium alloy molded part.Type: GrantFiled: August 28, 2012Date of Patent: August 2, 2016Assignee: Syntellix AGInventors: Volkmar Neubert, Robert Schavan

Publication number: 20110295325Abstract: A bone plate includes an upper surface, a bone contacting surface, and at least one hole extending through the upper and bone contacting surfaces. The bone plate defines a longitudinal axis. The at least one hole defines a central axis and is elongated in a direction substantially aligned with the longitudinal axis. The hole may include a threaded portion and a non-threaded portion, and the threaded portion may extend through an angle of between about 190° and about 280° with respect to the central axis.Type: ApplicationFiled: June 2, 2011Publication date: December 1, 2011Inventors: Michael WAGNER, Robert FRIGG, Robert SCHAVAN

Patent number: 6206881Abstract: A bone plating system for the internal stabilization of a fractured bone is disclosed. The system includes a bone plate having a plurality of conical plate holes tapering toward a bone contact surface and at least two bone screws for anchoring the bone plate to a bone. The screws have a conical head with a textured or structured lateral outside surface which is greater in hardness than the portion of the bone plate which is proximal to the plate holes. The present system provides positive locking between the screw heads and the plate holes.Type: GrantFiled: February 27, 1998Date of Patent: March 27, 2001Assignee: Synthes (USA)Inventors: Robert Frigg, Robert Schavan, Markus Hehli
