  • Patent number: 5497789
    Abstract: A padding and medicating device for corns, hammertoes, bunions, blisters, and the like comprising a noncompressible, thermoplastic, oleaginous, viscoelastic gel directly impregnated onto a carrier structure of elastic fabric. The ultrasoft gel is retained on and compressed against the body part being treated by the elastic tension of the fabric which causes the noncompressible gel to expand radially outward, flow over the lesion, and conform to the shape of the lesion in a manner which dissipates externally-applied pressure equally throughout the fabric-gel-tissue system. The invention also internally absorbs frictional or horizontal shearing forces, delivers a therapeutically significant dose of a lubricating, soothing, and emolifying oil such as Mineral Oil U.S.P., and is further capable of delivering a pharmacologically active substance to the foot lesion.

  • Patent number: 5415866
    Abstract: A drug delivery system for the topical administration of medication which utilizes a viscoelastic gel pad having a liquid fraction, wherein the medication is incorporated within the liquid fraction, the viscoelastic gel pad being partially encapsulated between two layers of liquid fraction impermeable material which are joined together to form a seal about the periphery of the gel pad so as to control migration of the pad, and the medicating skin contact of the pad is limited to a drug delivery aperture formed in the skin-contacting layer of liquid fraction impermeable material. The aperture-containing layer, which contacts a wearer's skin, may be provided with a pressure sensitive adhesive. The invention is exemplified in a topical anesthetic delivery system wherein a viscoelastic gel pad, partially encapsulated by transparent alcohol and water impermeable layers, has an alcohol and water liquid fraction in which is dissolved lidocaine base.

  • Patent number: 5330452
    Abstract: A topical medicating device includes a transparent viscoelastic gel pad having one or more pharmacologically-active substances incorporated therein; a sheet of transparent, impermeable, and elastic material providing an occlusive layer adjacent to the upper surface of the viscoelastic gel pad; an elastic retaining ring perimetrically surrounding the viscoelastic gel pad to prevent migration due to external pressure; and a porous meshwork attached to the elastic retaining ring so as to additionally anchor the gel pad from migration. The porous meshwork member may be located at the surface of the viscoelastic gel pad opposite the aforementioned occlusive covering sheet, or may run through the viscoelastic gel pad in its anchoring function. The viscoelastic gel pad, occlusive covering sheet, and retaining ring with porous meshwork may be affixed to a target skin surface of the patient by an adhesive tape bandage with a visual access opening.

  • Patent number: 5181914
    Abstract: A medicating device for human nails and adjacent tissue which, in the preferred embodiment, includes a transparent viscoelastic gel pad having one or more pharmacologically-active substances incorporated therein; a sheet of transparent, impermeable, and elastic material providing an occlusive layer adjacent to the upper surface of the viscoelastic gel pad; an elastic retaining ring perimetrically surrounding the viscoelastic gel pad to prevent migration due to shoe pressure; and a porous meshwork attached to the elastic retaining ring so as to additionally anchor the gel pad from migration. The porous meshwork member may be located at the surface of the viscoelastic gel pad opposite the occlusive covering sheet, or may run through the viscoelastic gel pad in its anchoring function.

  • Patent number: 5167649
    Abstract: A drug delivery system for the removal of dermal lesions which includes a pad of viscoelastic rubber and oil gel, perfused with a pharmacologically active substance, which is partially encapsulated between a first layer of oil and water impermeable material and a second layer of oil and water impermeable material. The second layer includes an aperture, corresponding to the dimension of the dermal lesion, which is smaller than, and located within, the periphery of the adjacent medicated viscoelastic rubber and oil gel pad. The two layers of oil and water impermeable material are bonded together to form a seal about the periphery of the viscoelastic rubber and oil gel pad. The surface of the patch which is affixed to a wearer's skin is provided with a pressure sensitive adhesive. The viscoelastic rubber and oil pad and the encapsulating layers preferably are transparent.

  • Patent number: 5098421
    Abstract: A padding and medicating device for the human foot comprising a sheet structure, preferably of an elastic fabric material and partially coated on one surface with a pressure sensitive adhesive, in combination with a pad of viscoelastic gelatinous material impregnated onto a portion of the same surface of the sheet structure as the pressure sensitive adhesive. The pad of viscoelastic gelatinous material is preferably made with an oleaginous plasticizer such as Mineral Oil USP, and may contain one or more pharmacologically active agents. The sheet structure is oil impervious or a separating layer of material impervious to the oleaginous plasticizer is incorporated on either surface of the sheet structure adjacent to the area of the sheet structure to be impregnated with the viscoelastic gelatinous material to prevent the oleaginous plasticizer from bleeding onto the sock or shoe of the wearer.

  • Patent number: 4842931
    Abstract: An affixable pad for corns, calluses, bunions, and the like, made from a soft viscoelastic gel material. Preferably, the gel contains a high percentage of plasticizing oil such as Mineral Oil U.S.P. The gel is impregnated onto an elastic fabric, such as Spandex, which allows the gel to flow around a lesion and equalize pressure in a superior manner.
