  • Patent number: 5250043
    Abstract: A bandage including a superabsorbent pad covered by a porous cover pad placed on a thin, flexible hydrocolloid adhesive layer leaving a portion of the adhesive layer around the pads as an adhesive border is disclosed. One side of the adhesive layer is laminated to a polymeric backing or non-woven fabric layer and a protective cover layer is applied over the pads and border portion. The protective cover layer may be silicone coated release paper and the bandage may be subjected to a vacuum thus forming the adhesive layer to the pads resulting in the border portion being substantially coplanar with the exposed surface of the cover pad overlaying the superabsorbent pad.

  • Patent number: 5206026
    Abstract: In accordance with the present invention an instantaneous delivery film useful in the delivery of a therapeutic agent to a wound site is provided. The present delivery film comprises a therapeutic agent, e.g. an enzyme or medicament, incorporated into a delivery material which forms the film. The delivery material is capable of rapidly dissolving in aqueous and saline solutions and comprises a water soluble and nonaqueous-solvent soluble film-forming polymer in an amount of from about 20 to about 100 percent by weight of the delivery material, and a plasticizer in an amount of from about 0 and 80 percent by weight of the delivery material. The present system is useful, for example, as a dry enzymatic debridement film suitable for the treatment of mammalian burns and ulcers.

  • Patent number: 5074852
    Abstract: Occlusive attaching means comprising a first relatively thick adhesive component to be secured to the skin around the stoma and a relatively thin flexible second adhesive component to be secured to the skin at a distance from the stoma. Both adhesive components include an occlusive adhesive layer formulated as a blend containing one or more water soluble or swellable hydrocolloids dispersed in polyisobutylene along with other optional ingredients. The attaching means can be utilized as part of a one or two-piece ostomy system.

  • Patent number: 4863474
    Abstract: This invention relates to a skeletal implant designed to provide a structure which bone can fill so as to biologically anchor the implant in position. A series of cutting edges are aligned on at least part of the surface and directed in a direction of relative movement between implant and bone. Bone removed by these edges is urged into a series of interconnecting spaces beneath the surface. Preferably a porous surface and the cutting edges are provided by perforated microcontoured sheet material. The three dimensional porosity formed by the perforations and contours results in bone debris impacted into the voids particularly at the time of implantation which will subsequently become integral with surrounding bone.

  • Patent number: 4531566
    Abstract: A pad eliminatable by heat prior to casting has a patterned surface and a non-porous backing. The pad is sized and shaped into at least part of the appliance and the patterned surface is conformed to the desired bonding surface contour. The patterned surface yields irregularities in the cast bonding surface which increases bondability.
