Abstract: An implant (1) for insertion into and permanent anchorage in bone tissue having an intraosseous anchoring structure (3). The anchoring structure (3) has a generally circular cross-section and comprises a first cylindrical section (11) of a first diameter, a second cylindrical section (13) of a second diameter less than the first diameter, said first and second cylindrical sections (11, 13) each being provided with a screw thread profile. The anchoring structure (3) also comprises a tapered connecting section (15) provided between an interconnecting said first and second cylindrical sections (11, 13).

Abstract: The invention relates to components for an improved system for pick-up impression making at a dental implantation site, including an abutment, an abutment replica and an impression coping. The invention also relates to a series of abutments and to a set comprising an abutment and an impression coping. The abutment includes an implant contacting region and a component support region, the component support region has a maximum diameter and extends coronally of the maximum diameter to a coronal end. The component support region also includes a component engagement arranged for releasable engagement with the component by linear displacement of the dental component in relation to the abutment. The component engagement is located at a position closer to the maximum diameter than to the coronal end of the component support region.

Abstract: The invention relates to a medical prosthetic device comprising a metal material, such as titanium or an alloy thereof, where the surface parts of the metal material are coated with a layer of a corresponding hydroxide material, such as titanium hydroxide. Preferably, the hydroxide layer comprises one or more biomolecule substances associated therewith.

Abstract: An implant with a surface modified for improved bio-compatiability consisting of a metal or an alloy thereof, said implant surface comprising a modified outer layer is disclosed, wherein said metal preferably is titanium, zirconium, hafnium or tantalum, and most preferably titanium, and said modified outer layer preferably comprises a hydride of said metal. Also a method for the production of such an implant is disclosed.

Abstract: A blood vessel such as a varicose vein is removed using a semi-rigid rod attached to a flexible thread. The thread is passed through the vein using the rod, which can then be removed. An end of the vein is affixed at a point between the ends of the thread, for example the midpoint. By pulling on the thread, the end of the vein is drawn back into the lumen of the vein, and the vein is progressively turned inside out. A stop can be fixed to the thread slightly beyond the point at which the vein is affixed to the thread, and prevents slipping along the thread. The thread can be at least twice as long as the vein, and alternately pulled in opposite directions.

Abstract: Bone tissue fragments are collected from liquid fluid being evacuated by suction from a surgical operation in bone tissue. Liquid is allowed to pass into the cylindrical sieve through one open end thereof and through the sieve wall from the inside to the outside thereof. Bone tissue fragments are collected on the inside surface of the sieve and are scraped off and deposited outside the sieve.

Abstract: A material for tissue separation at healing processes in injured soft tissue in mammals including man is described. The material consists of a porous flexible sheet of a protein-free bioresorbable polymer. Processes for preparation of the material and use thereof are also described.

Abstract: The invention relates to a thermistor, primarily intended for temperature measurement. The thermistor comprises at least two thermistor plates (14-17) on a carrier (10), adjacent to each other and connected in series. The plates are separated from each other by a preferably elongated gap (18) and the upper surfaces of said plates are largely covered by upper electrode surfaces (24-26). The thermistor plates (14-17) are arranged within a limited area of the carrier (10) so that the maximum aggregate area of the thermistor plates (14-17) is constant, whereas the size of each individual thermistor surface is variable by displacement of the position of the gap(s) (18) within the said limited area of the carrier (10), for adjustment of the total resistance of the thermistor to different values. The invention also relates to a procedure for manufacturing a thermistor.

Abstract: An implantable prosthesis for completely or partially replacing a tendon, a ligament or a cruciate ligament is characterized by a structure of bioresorbable material other than proteins, polypeptides and derivatives thereof, which structure exhibits longitudinal grooves or channels intended to server as initial propagation guides for new fibrous tissue.

Abstract: A rotating electric machine comprises a rotor and a stator each having a ferromagnetic core and being separated by a cylindrical air gap. The stator core is provided with three peripheral rings of magnet poles, the poles in each pole ring having alternate opposite polarities and the pole rings having the same number of poles and being spaced axially apart. The rotor core is provided with three peripheral ferromagnetic rings each having peripherally uniformly spaced teeth and spaces therebetween. These toothed rings are located opposite the magnet pole rings and each includes a number of teeth equal to half the number of magnet poles in each magnet pole ring. The mutual angular position between the magnet pole ring and the toothed ring in each associated pair is displaced peripherally in relation to the corresponding position in the other associated pairs by an angle equal to one third of the peripheral extension of a magnet pole pair.
