  • Patent number: 5919231
    Abstract: A device for insertion into a first opening in a body includes a device body having a longitudinal axis and a flexible first flange provided on an outside surface of the device body. The first flange has a deployed, use orientation in which it projects generally outwardly from the outside surface of the device body and an undeployed, insertion orientation in which it is resiliently deflected toward the device body. A retainer retains the flange in its insertion orientation. The retainer is constructed of a material soluble in a fluid.

  • Patent number: 5891081
    Abstract: There is provided a supporting rim structure of an open-ended tampon applicator for firmly supporting a tampon pledget that has been assembled in the applicator. The applicator supports the pledget around an intermediate section between its insertion end and its rear portion so that the insertion end is exposed outside of the applicator and the rear portion is inside of the applicator. In particular, the rim structure firmly supports the pledget against an axial force subjected to the pledget by a forming tool that forms the insertion end of the pledget into a rounded, hemispherical shape and yet readily allows the pledget to eject from the applicator. The rim structure has a shape that tapers angularly inward from the body of the applicator to form a rigid brace that counters the axial force subjected by the forming tool. Thus, while preventing the insertion end of the pledget from receding back into the applicator, the rim structure allows the pledget to easily eject from the applicator.

  • Patent number: 5825958
    Abstract: A hand held laser device is disclosed including a handpiece coupled to a source of laser energy by an optical fiber cable. A bias tensile stress is exerted on the fiber when the fiber and outer sheathing or tube are straight in-line. The bias tensile stress reduces compressional stress on the fiber when the fiber cable is bent. Moreover, the fiber is coupled to a disposable fiber in the handpiece to output light from the laser to a target area. The two fibers are precisely spaced close to one another to permit substantial lossless transmission of light without lenses or other focusing optics. Further, precision bearing devices are provided at opposite ends of the fiber cable in order to reduce torque on the fiber.

  • Patent number: 5814073
    Abstract: An inserter assembly is operable between a closed condition blocking movement of a suture anchor through the inserter assembly and an open condition in which the inserter assembly is ineffective to block movement of the anchor. The inserter assembly may have an end portion which pierces body tissue. In one embodiment, a tubular member has a plurality of segments which are moved from a closed condition to an open condition. In another embodiment, a plurality of wires extend along an inner side of a passage in a sheath. As the suture anchor slides along the wires, force is transmitted to the sheath to expand the sheath and operate the inserter assembly from the closed condition to the open condition. If desired, the wires may be omitted and the sheath resiliently expanded by a member which encloses the suture anchor. Indicia may be provided to indicate the depth to which the inserter assembly is inserted into body tissue.

The apparatus includes a first punch having an outside diameter which is sized slightly less than the inside diameter of the first member. This enables the first punch to slide within the first member from the second end toward the first end.

  • Patent number: 4857044
    Abstract: A compact tampon applicator is disclosed having a hollow first tube with a forward end and a rearward end. A tampon is slidably positioned within the first tube. The tampon has a longitudinally aligned central aperture formed therein which is open at both ends and has a withdrawal string attached thereto. The applicator also contains a radially expandable second tube having a forward end and a rearward end. The forward end is initially retained in the central aperture of the tampon and the rearward end initially extends out of the rearward end of the first tube. The second tube is capable of expanding radially once the forward end is removed from the tampon such that the second tube acquires a larger diameter and can be manually moved forward to eject the tampon from the first tube.

  • Patent number: 4620534
    Abstract: An apparatus for insertion of an intravaginal article into a mammalian female comprises a sleeve, a tube movably received within the sleeve, and a plunger adapted to release an intravaginal article from the tube. An anterior portion of the sleeve is adapted to be inserted within a segment of the reproductive tract of the female that is adjacent to the vulva and an anterior portion of the tube is adapted to be inserted within the tract to a point deeper than the segment, such that contaminants in the segment are not carried to the deeper point by the tube. A method for inserting an intravaginal article is also described.

  • Patent number: 4614182
    Abstract: The applicator for inserting a pessary into the uterus, which pessary comprises a chain combined with a distal coil screwable into the base of the uterus. The applicator has an inner shaft, which received the chain in its leading end, installed in an outer shaft and with its leading end securing the nearer of the coil in a formlocked or forcelocked manner, as well as a handle at the opposite end of the shaft whose rotation and axial displacement allow screwing the coil out of the outer shaft and into the base of the uterus to the extend of its longitudinal dimension. The outer and inner shafts are withdrawable from the uterus with respect to the screwed-in coil and chain which are to be released, after completion of the application.

  • Patent number: 4588395
    Abstract: A device and method are provided for disposing a quantity of matter at a select location within an animal or human body. In one form, the matter is a solid material, such as medication which dissolves with time, a source of radiation such as gamma radiation, a sensor or transducer in a housing which includes a short wave transmitter or other material or device which is operable to beneficially effect human tissue or body function when it is inserted into the body. The material is retained within a housing located at an end of a flexible tube or catheter which is inserted into a body cavity and is manipulated from the other end thereof to a predetermined location within the body cavity. Suitable actuating means located at the external end of the catheter is operated, when the head end thereof is at a predetermined location within the human body, to cause the material supported within the head to be ejected therefrom.

  • Patent number: 4496341
    Abstract: Apparatus is disclosed which may be utilized to package vaginal medication and may also be utilized in the application of such medication. The apparatus includes a flexible tubular membrane with an open end and a closed end. The closed end is axially depressed into the tubular membrane and forms a cavity into which the medication is placed. During packaging, a sealing cap is placed over the cavity and encloses the cavity and the medication. To utilize the apparatus for application of medication, the tubular membrane is slipped over a hollow tubular applicator and a piston member is inserted into the hollow tubular applicator. The piston member is utilized to outwardly extend the closed end of the tubular membrane and dispense the medication. After utilization, the tubular membrane is removed from the hollow tubular applicator and may be disposed of, thus preserving the sanitary condition of the applicator.

  • Patent number: 4479791
    Abstract: A tampon applicator of the telescoping tube type including an ejector tube adapted to store a tampon in its distal end, a plurality of fingers formed in said distal end, an outer tube slip fit over the ejector tube, directionally-locking inward projections fixed within the distal end of said outer tube so as to pass between said fingers and engage a tampon carried therein thus securing the latter relative to said outer tube while permitting only distal expulsion therefrom. Said applicator charged with a tampon is packaged and stored in a telescopically collapsed position. It is activated for use by partial withdrawal of the ejector tube from the outer tube until the fingers of the ejector tube pass beyond the tampon and catch behind the proximal end of said tampon. The applicator is then used in the usual manner by telescopically collapsing the ejector tube into the outer tube, whereby the ejector tube serves as a plunger bearing against the proximal end of the tampon to expel the latter.
