| 20090023109 | BONE ANCHOR FIXTURE FOR A MEDICAL PROSTHESIS - A screw-shaped anchoring fixture for anchoring a prosthesis in the skull bone. The anchoring fixture comprises a main body configured to be implanted into the bone and a flange configured to function as a stop to prevent the main body from completely penetrating through the bone. The main body comprises a distal tapered apical portion, a first portion, and a second portion. The inner diameter of the second portion is greater than the inner diameter of the first portion. The method for inserting the anchoring fixture includes providing the anchoring fixture, drilling a hole, and inserting the anchoring fixture into the hole until the flange contacts the skull bone, wherein the hole has a diameter that is greater than the inner diameter of the first portion and less than the outer diameter of the second portion. | 01-22-2009 |
| 20090082817 | COUPLING APPARATUS FOR A BONE ANCHORED HEARING DEVICE - A coupling apparatus for a bone anchored hearing device for anchoring hearing aid devices or extra-oral prostheses in the form of ear and orbital prostheses in the skull bone. The apparatus comprises a screw-shaped anchoring fixture configured to be inserted into the skull bone and a skin-penetrating abutment coupled to the fixture by a screw connection. The fixture comprises a main body with an external screw thread and a flange having a substantially planar bottom surface. The flange is configured to stop the anchoring element from penetrating through the skull bone. The skin-penetrating abutment comprises a substantially conical outer surface. The upper end surface of the fixture is designed with an open cavity with a tapered inner contour forming a seat for the bottom part of the abutment. The bottom part of the abutment is configured to create a good connecting fit between the fixture and abutment. | 03-26-2009 |
| 20100179375 | VIBRATOR FOR BONE CONDUCTING HEARING DEVICES - A vibrator for generating vibrations in a bone conducting hearing device, i.e. a hearing device of the type in which the sound information is mechanically transmitted via the skull bone directly to the inner ear of a person. The vibratory movements are provided by a piezo-electric or magneto-elastic element arranged to transfer the vibrations via the skull bone from the area behind the outer ear to the inner ear. The piezo-electric or magneto-elastic element is arranged to be at least partially implanted in a surgically drilled hole directly into the mastoid bone behind the outer ear so that the vibrations are transferred directly from the element to the bone and transferred in the skull bone to the inner ear. The element is encapsulated with a bone integrating material, such as titanium or various biocompatible ceramic materials or coatings and is disc shaped and acts with a radial expansion upon electrical stimulation so that longitudinal sound waves are induced into the skull bone. | 07-15-2010 |
| 20100298626 | BONE CONDUCTION DEVICE HAVING A MULTILAYER PIEZOELECTRIC ELEMENT - A bone conduction device comprising a multilayer piezoelectric element. The multilayer piezoelectric element comprises two stacked piezoelectric layers, and a flexible passive layer disposed between the piezoelectric layers. The device also comprises a mass component attached to the multilayer piezoelectric element; and a coupling attached to the multilayer piezoelectric element configured to transfer mechanical forces generated by the multilayer piezoelectric element and the mass component to a recipient's skull. | 11-25-2010 |

| 20080319173 | Blood group antigen fusion polypeptides and methods of use thereof - The present invention provides compositions and methods for treating or preventing antibody mediated graft rejection. | 12-25-2008 |
| 20090280104 | COMPOSITIONS AND METHODS FOR INHIBITING SHIGA TOXIN AND SHIGA-LIKE TOXIN - The present invention provides compositions and methods for treating or preventing infection by shiga toxin producing bacteria. | 11-12-2009 |
| 20090280134 | COMPOSITIONS AND METHODS FOR INHIBITING TOXIN A FROM CLOSTRIDIUM DIFFICILE - The present invention provides compositions and methods for treating or preventing infection by Toxin A producing bacteria. | 11-12-2009 |
| 20090286963 | ANTIGENIC FUSION PROTEIN CARRYING GAL ALPHA1,3GAL EPITOPES - The present invention relates to an antigenic fusionprotein, which carries multiple GalĪ±1,3Gal epitopes. The fusion protein according to the invention may also be comprised of a heavily glycosylated mucin part, which mediates binding to selectins, such as PSGL-1, and a part, which exhibits immunoglobulin properties, such as the Fc part of IgG. The fusionprotein according to the invention is preferably used as an absorber to prevent a hyperacute rejection of a xenotransplant, such as a pig tissue or organ transplanted into a human patient. In addition, the invention relates to a method for the prevention of a hyperacute rejection reaction in a patient who is to receive a xenotransplant. | 11-19-2009 |

| 20110064359 | COMPACT OPTICAL FIBRE COMPONENT PACKAGE - The present invention relates to an optical component, which comprises an optical fibre, which has a minimal functional arc radius in each point thereof, and which includes a thermally compensated portion, and a Bragg grating provided in a region of the thermally compensated portion. The optical fibre component comprises furthermore a temperature-compensating structure, which holds the thermally compensated portion of the optical fibre under tension in a linear direction for athermalizing the Bragg grating, and a housing for mechanical protection of the Bragg grating, which is provided with at least a first lead-through, and which housing has a maximal extension in the linear direction from a first housing end to a second housing end. The first lead-through has an exit end located outside the housing and an entrance end located inside the housing. The optical fibre furthermore includes at least a first connecting portion, which extends from a first end of the thermally compensated portion to and through the first lead-through, and at least a first exit portion which extends from a lead-through exit end of the first connecting portion. The first lead-through is located and arranged such that the first exit portion is bendable to the minimal functional arc radius without protruding more than half the minimal functional arc radius in the linear direction beyond the first housing, also when a shorter exit portion is extended to a length equal to the circumference of a circle with the minimal functional arc radius. | 03-17-2011 |
