  • Patent number: 5730154
    Abstract: There is disclosed a splint prosthesis for body limbs, such as fingers, toes, arms and legs. The splint prosthesis includes a sheath, having a size and thickness which can be varied as to application, e.g., from 1 to about 3 millimeters in thickness for toe and finger splints up to several centimeters for larger body limbs such as legs and arms. The splint prosthesis has at least two longitudinal retractable stiffeners embedded within said sheath and oriented so that the stiffeners have a stable coiled configuration and a stable extended configuration. The stiffeners are formed of thin, elastic sheet material which can be rolled into a coil, and which readily unrolls. At least two stiffeners are provided, extending longitudinally along the extended sheath configuration and these are spaced apart by an angular increment which is sufficient to maintain the sheath in its extended configuration.

  • Patent number: 5509891
    Abstract: There disclosed a prothesis for male erectile dysfunction. The prothesis comprises a sheath, quite similar in size and thickness to a conventional condom which has at least two longitudinal retractable stiffeners embedded within said sheath and oriented so that the stiffener has a stable coiled configuration and a stable extended configuration. The stiffeners are formed of thin, elastic sheet material which can be rolled into a coil, and which readily unrolls. At least two stiffeners are provided, extending longitudinally along the extended sheath configuration and these are spaced apart by an angular increment which is sufficient to maintain the sheath in its extended configuration. The material of the sheath is sufficiently elastic to permit the stiffener to be roll and unrolled.
