Patent number: 8758350Abstract: A device for clamping fixation elements, which have been inserted into bone, for manipulating fragments of a fractured bone. The device incorporating a hollow body with a cavity having a wall, a clamping body moveable within the cavity between a first position and a second position, and a clamping device operably connected to the clamping body for moving the clamping body between the first position and the second position. The device being sized and configured so that when the clamping body is in the first position a free end of the fixation element(s) may be positioned between the clamping body and the wall of the cavity. Once the fixation element(s) is properly positioned within the cavity, the clamping device may be used to move the clamping body into the cavity, thereby wedging the fixation element(s) between the clamping body and the wall of the cavity. A bone fragment may then be manipulated using the device.Type: GrantFiled: October 13, 2010Date of Patent: June 24, 2014Assignee: Depuy Synthes Products, LLCInventors: Daniel Schmucki, Patrizio Frigeri, Peter Messmer

Publication number: 20110048409Abstract: In one instance, a solar collector uses vacuum to maintain or help maintain its components in an assembled position and to insulate or help insulate a plurality of thermal conduits. Curved members, edge members, and end caps combine to form an interior space and to provide a system with substantially no bending forces. An absorption-and-tensioning member traverses the interior space and keeps the curved members from collapsing when placed under partial or complete vacuum and helps absorb thermal energy. The edge members have seats for receiving the curved members that help firmly press the curved members into the seats to form a desired seal. Other solar collector systems, features, and methods are disclosed.Type: ApplicationFiled: July 23, 2010Publication date: March 3, 2011Applicant: Green Partners Technology Holdings GmbHInventor: Hans-Peter Messmer

Publication number: 20100319654Abstract: A rotary vane engine includes a sealing area that prevents or reduces carry-back between portions of the rotary vane engine. The rotary vane engine includes a stator housing having a stator wall with a first portion and a second portion. The first portion may be formed with a curvature that substantially matches the curvature of a rotor and provides the sealing. The rotary vane engine may include a first insert member for allowing adjustment of a fluid manipulation ratio (compression or expansion).Type: ApplicationFiled: June 15, 2010Publication date: December 23, 2010Inventor: Hans-Peter MESSMER

Publication number: 20090314005Abstract: The method for operating a piston engine system that includes modifying valve timing such that the gas displaced from the piston chamber is at a pressure and temperature nearly equivalent to the temperature and pressure at the end of the combustion stroke rather than being throttled as is the case for traditionally valve timings. When the high temperature and pressure gas enters an exhaust channel, thermally isolating means may line the exhaust channel such that the high temperature of the exhaust gas is maintained. A heat exchanger and an expander may be placed along the exhaust channel such that the high temperature and pressure of the exhaust gas are captured for useful work.Type: ApplicationFiled: December 19, 2008Publication date: December 24, 2009Inventor: Hans-Peter Messmer

Publication number: 20090158739Abstract: Systems and methods utilizing turbines, including a compressor turbine with a vaporizable liquid delivery device, are presented. A compressor turbine uses the evaporation of a vaporizable liquid at or near thermal equilibrium from the vaporizable liquid delivery device during the compression. The vapor created thereby typically carries the thermal energy discharged after the gas turbine cycle. The amount of liquid vaporized during compression, the length of time vaporization takes, the proximity to thermal equilibrium at which vaporization occurs, the amount of thermal energy recovered by recuperation, and the temperature at the inlet of the combustion chamber are generally interrelated parameters that can be controlled to increase efficiency.Type: ApplicationFiled: December 19, 2008Publication date: June 25, 2009Inventor: Hans-Peter Messmer

Patent number: 6855152Abstract: A device to be used in combination with a surgical navigation system for defining the position of a straight line determined by an operating surgeon within a three-dimensional coordinate system in an operating theater. The devices includes a body (1) with a surface (2) and at least three markers (3) which emit waves (19) and the position of which can be determined within a three-dimensional coordinate system by a position detector belonging to the surgical navigation system. A laser (4) mounted on the body (1) emits a laser beam (5), directed away from the body (1), which has a geometrical central beam (6) and a wavelength in the visible range. The laser beam (5) is emitted in a geometrically defined position relative to the markers (3) so that the position of the central beam (6) relative to the three-dimensional coordinate system can be calculated from the previously measured positions of the markers (3) by a computer, which is also part of the surgical navigation system.Type: GrantFiled: December 18, 2000Date of Patent: February 15, 2005Assignee: Synthes AG ChurInventors: Norbert Suhm, Peter Messmer, Pietro Regazzoni, Markus Hehli, Paul Muller

Patent number: 6814490Abstract: A device for moving an X-ray apparatus embodied in the form of a C-bow (9) in a controlled manner, the C-bow (9) being mounted on a pedestal (31) provided with motor-driven rollers (3) controllable in their direction of travel in such a way that it is displaceable in parallel in relation to at least two axes (18;19) and rotatable relative to three axes (18; 19, 21), each movement of the C-bow (9) with respect to a coordinate system (29) which is stationary relative to the room being carried out via controllable drive devices (6;7;37;38). These drive devices (6; 7; 37; 38) are controlled either by means of a control device (39;48) or via a computer (23), said control device being operated either via a sterile control console or by voice control. Any positions and projections of the C-bow (9) that have once been adjusted may be stored in the computer (23), so that a desired position and projection may be reproduced again.Type: GrantFiled: September 23, 2002Date of Patent: November 9, 2004Assignee: AO-Entwicklungsinstitut DavosInventors: Norbert Suhm, Peter Messmer, Pietro Regazzoni, Paul Müller, Urs Bopp, Markus Hehli, Silvio Koller

Publication number: 20030012342Abstract: A device to be used in combination with a surgical navigation system for defining the position of a straight line determined by an operating surgeon within a three-dimensional coordinate system in an operating theatre, including a body (1) with a surface (2) and at least three markers (3) which emit waves (19) and the position of which can be determined within a tree-dimensional coordinate system by a position detector belonging to the surgical navigation system. A laser (4) mounted on said body (1) emits a laser beam (5), directed away from the body (1), which has a geometrical central beam (6) and a wave length in the visible range. The laser beam (5) is emitted in a geometrically defined position in relation to the markers (3) so that the position of the central beam (6) in relation to the three-dimensional coordinate system can be calculated from the previously measured positions of said markers (3) by a computer which is also part of the surgical navigation system.Type: ApplicationFiled: August 15, 2002Publication date: January 16, 2003Inventors: Norbert Suhm, Peter Messmer, Pietro Regazzoni, Markus Hehli, Paul Muller
