  • Patent number: 4863450
    Abstract: The invention relates to a tampon (10), to the essentially cylindrical circumferential surface of which a liquid-permeable, thermoplastic material is fastened, with the application of pressure and heat. The dome-like constriction (10b) at the introduction end (10a) and the withdrawal end (10c) of the tampon (10) remain free of the liquid-permeable, thermoplastic material. The fastening of the liquid-permeable material to the outer surface of the absorbent material of the tampon (10), which consists of a nonwoven ribbon section rolled up on itself and pressed radially to give the final form of the tampon (10), guarantees that the high absorbency of the nonwoven fibre material, based on capillary action, continues through the liquid-permeable, thermoplastic material onto its outside. In addition, the liquid-permeable material offers protection against fibres becoming detached and makes it easier to introduce the tampon into and remove it from the body cavity.

  • Patent number: 4850963
    Abstract: Methods and apparatus for maintaining urinary continence in normally incontinent individuals. The present invention involves the non-surgical implantation of a bolus of ferromagnetic material into the bladder. The bolus of ferromagnetic material may comprise a biocompatible membrane, containing a ferromagnetic material. The bolus will normally rest at the juncture between the bladder and the urethra and will prevent the flow of urine from the bladder into the urethra. Essentially, the bolus serves as a seal between the urethra and the bladder. When it is desired to void the bladder, the ferromagnetic bolus is moved out of the intersection between the bladder and the urethra by positioning a magnet along the external surface of the person's body and manipulating the magnet until the desired movement of the bolus is accomplished. Movement of the magnet is sufficient to displace the bolus such that flow may be initiated from the bladder into the urethra.

  • Patent number: 4846802
    Abstract: A shortened tampon applicator of the telescoping tube type employs an ejector tube to store a tampon in its distal end and an outer tube disposed by a slip fit thereover to thus shorten the overall length of the tampon and applicator assembly. Directionally-locking inward flaps fixed within the distal end of said outer tube engage the distal end of the tampon stored in the ejector tube thus securing the latter relative to said outer tube while permitting only distal expulsion therefrom. The ejector tube preferably has inwardly biased flexible portions at its distal end which serve to catch behind the proximal end of the tampon. In the preferred version, the inwardly biased portions are unique undulations at the blunt distal end of the ejector tube which advantageously cooperatively functions with a tampon having an enlarged tail.
