  • Patent number: 7115792
    Abstract: The present invention is a scar-reducing plaster and a method for preparing scar-reducing plasters. The scar-reducing plasters comprise a backing film comprising an air- and water vapor-pervious and water-impervious polymer layer, and a breathable and adhesive polyurethane xerogel matrix layer that coats the backing film. The polyurethane xerogel matrix layer includes a central scar contact region and an edge region, wherein the scar contact region merges with the edge region and the thickness of the edge region decreases from the scar contact region to a thickness of from 5 to 150 ?m at the edge of the polyurethane xerogel matrix layer. The scar-reducing plasters of the present invention have a reduced tendency to peel off during normal use.

  • Patent number: 5265786
    Abstract: An apparatus for placing surgical staples which are moved one after another from a staple support onto a lower die and are deformed there using an upper die, by lowering and further adjusting the upper die onto the particular staple to be placed situated on the lower die, wherein the staple is deformed by bending around the lower die and then separated from the lower die using an ejector, is described. A particularly simple and function-safe design for the ejector system is produced in that the ejector can be displaced in a straight line and is brought to rest against the limbs of the implanted staple by means of a head below the lower die when adjusting to its second position.

  • Patent number: 5176306
    Abstract: An instrument for setting wound clamps consists of first and second parts detachably connected by means of a first connection. The first part, which is a disposable part, receives a magazine containing wound clamps, and tools for deforming and implanting the wound clamps. The second part has handles for operating the tools. When the instrument is being operated, forces are generated which may cause the two parts of the instrument to become separated. A second connection between the two parts of the instrument, which connection is only effective during the operation of the instrument is, therefore, provided.

  • Patent number: 5147381
    Abstract: A surgical clip for closing the margins of a wound, is disclosed, which clip consists of a bridge and two legs having cutting edges at their ends and projecting from opposite ends of the bridge. Each leg has a part formed as an arc of a circle which adjoins the bridge, and a free ended straight section including the cutting edge of the leg, extending from the arcuate part of the leg. For reducing trama when the clip is implanted and for maintaining eversion of the wound margins after the clip has been implanted, the straight sections of the legs are set at an angle in the range of 2.5.degree. to 10.degree. with respect to the axis of symmetry of the clip.

  • Patent number: 5080275
    Abstract: There is disclosed a surgical instrument for implanting in bodily tissue, wound staples each comprising two legs and a crown connecting the legs. The staples are moved in succession out of a magazine onto an anvil, to be deformed thereon by means of a driver. The driver is lowered from a position of rest towards the staple on the anvil, and is further moved to close the staple on the anvil by bending the staple theraround, and to insert the legs of the staple into the bodily tissue. For problem-free and symmmetrical deformation of the staple, a hold-down device is lowered onto the anvil and upon deformation of the staple thereon presses the crown of the staple onto the anvil and so prevents the staple from moving laterally during its deformation.

  • Patent number: 4947834
    Abstract: A device is disclosed which comprises at least one sleeve having a number of chambers. The sleeve may be placed around the patient's extremity which is to be treated, and the chambers can be inflated and deflated by means of valves. To accomplish an optimum treatment of the patient and an uncomplicated construction of the device, all the valves are connected in series and arranged to be operated successively in cascade-fashion via common feed and control pipes which are connected only to the first valve, whilst downstream each pair of mutually adjacent valves are interconnected via sections of feed and control pipes. In each valve a valve member such as a diaphragm separates a supply volume of the valve, which is in constant communication with an infeeding feed pipe section and with the assoicated chamber, from a valve control volume which is in constant communication with the control pipe.

  • Patent number: 4643732
    Abstract: A heart valve prosthesis with a valve housing in the form of a ring and a curved valve which is mounted within the housing and which is hinged to the valve ring by means of a flat flexible small lug which, if appropriate, is drawn in one region through a slot in the valve ring, is characterized in that the valve and the ring each consist of two rigidly joined halves fitting respectively onto or into each other, and the end portions of the small lug in the form of a short strip are embedded "sandwich"-like between the valve halves on one side and between the ring halves on the other side.
