  • Patent number: 5019061
    Abstract: A tampon comprises a compacted tampon blank, which in turn is formed by winding a liquid-permeable strip and a string of absorbent material placed thereon to a roll and inserting strip-parts which project from the sides of the string, inwardly of the innermost turn or winding of the roll. In the process of manufacturing the tampon, the strip carrying the string can be wound around a first, tubular mandrel, and one strip-part can be inserted into the mandrel through one open mandrel-end located adjacent the inner edge of the strip-part. A second tubular mandrel is then inserted through the open end of the first mandrel and the first mandrel then withdrawn. With the second mandrel surrounded by the first, inserted strip-part and located with an open end adjacent the inner edge of the other strip-part, the other strip-part is inserted into the second mandrel, which is then withdrawn from the thus formed tampon blank, which is thereafter compacted or compressed.

  • Patent number: 5015228
    Abstract: A dressing device and method are described, for use with a needle that is injected into the skin. The dressing device comprises a cover sheet and a gel medium attached to the cover sheet, the gel medium being transparent and effective to reseal after being punctured by the needle. Most importantly, the gel medium includes a sterilizing agent.Injection of the needle into the skin occurs only after the needle penetrates the gel medium, so that the needle is disinfected or sterilized.

  • Patent number: 5015245
    Abstract: Disposable sanitary articles comprise paper treated with polycationic latexes as wet-strength agents. The paper has sufficient wet strength that it can serve as the backsheet for absorbent articles, garments, and the like. Thus, KYMENE is reacted, for example, with acrylic acid and cross-linked with styrene/butadiene to provide a polycationic latex which is used to treat paper to enhance its wet strength. Diapers, sanitary napkins, pantiliners, and the like, prepared from the foregoing materials are disclosed.

  • Patent number: 4997449
    Abstract: An artificial knee joint (10) with a clamping member (13) is provided with a peg (11) for attachment to a thigh shaft (12). The clamping member is pivotable against a braking member or barrel (19) located inside the knee joint housing when a vertical load (44) is applied to the knee joint to arrest the swiveling movement a leg part (26). The leg part accommodates the lower leg tube of a leg prosthesis as well as a traction strap (36) impelling the knee joint back into the straightened position. By this means an uncontrolled buckling of the artificial knee joint is prevented in the event that a prosthesis wearer stumbles.

  • Patent number: 4988352
    Abstract: An intraocular lens, folded on itself for insertion into an eye, is retained in the folded configuration by chilling until it becomes inflexible and loses its tendency to unfold. The folded, frozen lens is inserted into the eye and thaws in situ to restore it to its original unfolded configuration. The chilling obviates the need for special retaining means to hold the lens in the folded configuration for insertion, thereby facilitating the surgical procedure and enabling a smaller incision to be used. The lens may be frozen onto an inserter for positioning it within the eye. Apparatus for folding and freezing the lens is also disclosed.

  • Patent number: 4976269
    Abstract: Tissue needle for extracting a biopsy sample including a pistol style squeezable hand grip for single hand tissue needle operation during a biopsy procedure. A spring tensioned sliding cannula, including a configured cutting edge, is actuated by a squeeze trigger and cam arrangement to slide over a fixed position stylet for entry into a tissue sample area. A squeeze trigger manually cycles using one hand to obtain a biopsy sample contained in a tissue sample notch of the sharp stylet tip whereupon the tissue needle can then be manually withdrawn. The tissue needle can be left temporarily in position in the tissue sample area in preparation for additional sampling while the stylet is withdrawn independently of the cannula prior to other samplings after subsequent reinsertion of the stylet into the cannula.

  • Patent number: 4976727
    Abstract: In a surgical needle, marks of welding are left as they are on a welded portion between needle and pipe members so that the welded portion has a surface distinguishable from peripheral surfaces of the respective needle and pipe members. The welded portion may be composed of a plurality of peripherally spaced welded parts. In a manufacturing method of the surgical needle, a beam energy is applied from a beam energy emitting arrangement, toward an abutting line between the needle and pipe members, from a direction substantially perpendicular to the needle and pipe members, thereby welding them to each other. In a manufacturing apparatus, a rotational support arrangement is provided for supporting the needle and pipe members in such a manner that end faces of the respective needle and pipe members are abutted against each other at a location coincident with an optical axis of the laser beam, and for rotating the needle and pipe members about their respective axes.

  • Patent number: 4973323
    Abstract: As ostomy appliance having a collection pouch and a flexible faceplate, the faceplate including an outer ring of thin, microporous sheet material and an inner ring of flexible, thermoplastic film impervious to gases and body fluids. The outer microporous ring surrounds the inner ring so that their adjacent margins overlap and are sealed to each other. The faceplate also includes a barrier ring secured to the inner marginal portion of the microporous ring on the side opposite from the attachment of the impervious inner ring. A fluid-impervious annular seal is provided between the impervious inner ring and the barrier ring at a location radially inwardly from the microporous ring, thereby securing the parts together and isolating the inner margin of the microporous ring from contact by stomal fluids.

  • Patent number: 4969908
    Abstract: A lunate implant includes a one-piece, at least semi-rigid body defining a triquetrum face, a scaphoid face, a cupped, concave, distal surface adapted to articulate with the capitate bone, a proximal surface, a palmar surface and a dorsal surface. A pair of spaced, generally parallel suture passages extend between and open through the triquetrum and scaphoid faces. A pair of sutures are stitched to ligaments of the wrist. The ends of the sutures are passed through the suture passages so that one of the sutures has ends extending away from the triquetrum face and the other suture has ends extending away from the scaphoid face. The ends are grasped and the lunate implant is pulled down into the desired position in the distal carpal row of the wrist. The sutures are tied adjacent the implant to stabilize and position the implant.
