  • Patent number: 7771149
    Abstract: The invention relates to a combination of a screw member comprising a screw head, a threaded portion and a shank portion which is arranged between the screw head and the threaded portion and has an external diameter that is smaller than the external diameter of the threaded portion, a washer incorporating a passage opening for the screw member and a sleeve the internal diameter of which is greater than the external diameter of the threaded portion of the screw member, whereby said combination is producible in a simple manner but it is nevertheless ensured that the sleeve and the washer are held securely on the screw member.

  • Patent number: 6623523
    Abstract: A symmetrical, heart-shaped breast prosthesis has two identical notches which are arranged symmetrically with respect to a plane of symmetry dividing the prosthesis body into two equal halves and at an angle in the range between 30° and 90° between them, in such a way that, when the prosthesis is worn, only one of the two notches is essentially perpendicular to the longitudinal axis of the wearer's body. The notches have the effect that the prosthesis collapses slightly when the wearer is in the upright position and becomes flatter when the wearer is in the prostrate position. In the state when worn, the heart-shaped prosthesis which is symmetrical in the unshaped state becomes an asymmetrical prosthesis having a lateral branch and an upper branch which moves downwards when the wearer is in the upright position and slips upwards when the wearer is prostrate.

  • Patent number: 6451139
    Abstract: The invention relates to a breast prosthesis for breast-amputated women with a flexible plastic body comprising two plastic sheets connected to each other along their common edge and a plastic mass enclosed between the two plastic sheets, wherein the plastic body has a front side formed to resemble the contour of the natural breast and a back side capable of facing the torso of the person, and an elastically deformeable thin part secured with its edge to the back side of the plastic body. In order to improve the wear comfort of the breast prosthesis, the thin part is secured to the plastic body inside the common edge of the connected plastic sheets.

  • Patent number: 6136028
    Abstract: A breast prosthesis worn in a brassiere or the like. It has a prosthesis y having a front side in the shape of a natural breast, a back side with a recess and a prosthesis edge which follows a closed line on which the front side and the back side both end. The prosthesis body has a soft elastic silicone rubber compound which is enclosed without any voids in a bag consisting of two elastically expandable plastic films joined tightly together along the edge of the prosthesis. When the wearer is lying down, the prosthesis should assume a stretched form, where the front side is flattened slightly. When the wearer stands upright, the upper part should sag downward slightly, with the lower and middle areas of the front side having a somewhat greater bulge.

  • Patent number: 5607473
    Abstract: A breast prosthesis to be worn on the body of a person who has had a mastectomy includes a soft-elastic prosthetic body made of two plastic sheets which are connected to each other along a common edge, with a plastic mass being contained hollow-free between the plastic sheets. The prosthetic body has a front side resembling in its form the natural breast and a rear side which faces the wearer's body. A fabric member covers the rear side and is attached solely to the peripheral edge of the plastic sheets of the prosthetic body to thereby increase the comfort of wearing the breast prosthesis. The fabric member is suitably made of thermoplastic material, with the welding of the plastic sheets and the welding of the fabric member with the plastic sheets being carried out in a single working step.
