20120083869 | DELIVERY SYSTEM FOR A PROSTHESIS - The invention provides a delivery system for a prosthesis, said delivery system comprising a catheter shaft with a distal end, a proximal end and a longitudinal axis, a space for a prosthesis with a distal end and a proximal end, the space being at the distal end of the catheter shaft, a sheath with a proximal end and a distal end, the sheath being disposed at the distal end of catheter shaft so as to surround the space, a pusher element attached to the distal end of the catheter shaft and arranged at the proximal end of the space for abutting prosthesis, a pull element with a longitudinal axis, the pull element running the length of the catheter shaft and having a distal end attached to the proximal end of the sheath and a proximal end for pulling the pull element proximally, thereby retracting the sheath proximally relative to the prosthesis space, and at least one fixation element having a proximal end and a distal end and being disposed within a flexible portion of the length of the shaft that lies between the proximal end of the sheath and the proximal end of the catheter shaft. The fixation element serves to limit a radial distance between the axis of the pull element outside the shaft and the axis of the catheter shaft along the length of the fixation element whenever a tensile stress in the pull element results in an endwise compressive stress on the shaft and a tendency of the shaft to bow, relative to the pull element. | 04-05-2012 |
20120157935 | Force-Transmitting Element for Use in Medical Catheters - The present invention relates to a force-transmitting element for a medical catheter. The element may, for example, be used in catheter introducers or stent delivery systems. An embodiment of the present invention may comprise a tube and a tubular sleeve, wherein the tube has formed through the wall thickness a plurality of axially-distributed slits formed so that the extent of each slit in the circumferential direction exceeds half of the circumference of the tube such that, when the tube is longitudinally flexed into a curve, the slits on the outside of the curve become relatively more opened and, when the element is subject to no external endwise compressive forces, the tube is retained by the tubular sleeve in a state of endwise compression such that the slits are relatively more closed than if the sleeve were absent. | 06-21-2012 |

20120255387 | DEVICE FOR ACTUATING A SHIFTING ELEMENT WITH TWO SHIFTING ELEMENT HALVES - A mechanism for actuating a shifting element. A first shifting element half of a brake is axially fixedly connected to a drive machine output shaft, which, when rotational movement of the output shaft equals the disengaging movement of the shifting element, is rotationally fixed to the output shaft. In the event of an engaging force, opposite the disengaging movement of the shifting element, an axial force acts on the output shaft, such that the first shifting element half frictionally engages with an axially and rotationally fixed second shifting element half. In the event of a disengaging force that acts in the disengaging direction of the shifting element, an axial force acts on the motor output shaft such that the first shifting element half of the brake is moved out of frictional engagement with the second shifting element half. | 10-11-2012 |
20120255828 | DEVICE FOR CHANGING AN OPERATIONAL STATUS OF A SHIFTING ELEMENT WITH TWO SHIFTING ELEMENT HALVES - A mechanism for changing the operating condition of a shifting element having two shifting element halves, which can either be functionally connected to connect two components or disengaged to break the connection between the components. The mechanism includes a drive machine and a drive converter unit in the area of which rotary drive motion of the drive machine can be converted into a translational actuation movement of the shifting element. A spring device is associated with the drive converter unit, whose spring force assists with actuating the shifting element in the engaging direction. The spring device includes an approximately circular flat spring element which, in at least one area of the drive converter unit, is in contact with at least one cam, whose stress condition varies as a function of an operating condition of the drive converter unit and is designed to be rotationally fixed. | 10-11-2012 |
