  • Patent number: 5986166
    Abstract: An absorbent product comprising a liquid permeable surface sheet, a liquid nonpermeable back sheet and an absorbent layer located therebetween, wherein the absorbent layer comprises a water nonswellable synthetic fiber (a) and optionally cellulose fiber (b), and a water-absorbent resin (c), with the weight ratio of (a):(b) being (100 to 20):(0 to 80) and the percentage content of (c) based on the weight sum of (a), (b) and (c) is 25 to 75 weight %. The absorbent layer is treated with polyoxyalkylene-modified silicone surface active agent (d1) and/or a nonsilicone surface active agent having HLB of 8 to 14 (d2). Absorbent products of the present invention exhibit excellent shape retention in the moist state and good permeability and diffusibility for the absorbed liquid. Accordingly, they provide excellent surface dryness, reduced leakage and thus can be comfortably used for a long time and effectively applied to disposable diapers, sanitary napkins and incontinence pads.

  • Patent number: 5981825
    Abstract: An anatomically specific, bioresorbable, implant device for facilitating the healing of voids in bone, cartilage and soft tissue is disclosed. A preferred embodiment of using the implant device for facilitating the healing of a human joint lesion includes a cartilage region invested with an alginate microstructure joined with a subchondral bone region invested with a hyaluronan microstructure. The alginate selectively dispersed in the cartilage region enhances the environment for chondrocytes to grow articular cartilage. The hyaluronan selectively dispersed in the subchondral bone region enhances the environment for mesenchymal cells which migrate into that region's macrostructure and which differentiate into osteoblasts. The microstructures can be invested at varying concentrations in the regions. A hydrophobic barrier, strategically positioned within the subchondral bone region macrostructure, shields the chondrocytes from the oxygenated blood in subchondral cancellous bone.

  • Patent number: 5957904
    Abstract: A female urinary collection device includes a receptacle pouch for collecting urine. The receptacle pouch includes a first area for securing adhesive strip to each buttock of a user to create a relatively rigid engagement of the device with the body. In the upper zone, there is a stretch loop and foam belt for securing the pouch around the waist. Inside the receptacle pouch, there is a reservoir of adsorbent material with a wick which exits the receptacle pouch through a tubing connected to an orifice in the receptacle. The receptacle pouch fits around the labia majora of the user. In some cases there are two outlets from the receptacle. The orifices are spaced from each other such that when a patient is lying on either one of her sides with the receptacle in place the one orifice would be relatively above the other thereby facilitating drainage of urine from the receptacle when the patient is lying on either one of her sides.

  • Patent number: 5957972
    Abstract: Autologous and synthetic vascular implants that possess an external monolayer of endothelial cells genetically modified to express at least one of a number of therapeutic agents useful for the inhibition of smooth muscle cell proliferation are provided. In the preferred embodiment of this invention, the endothelial cells coating the implant are genetically-modified to express and secrete the protein interferon-gamma. The use of such an implant in vascular and heart surgeries would substantially increase both the patency of the graft and the rate of surgical success by inhibiting the expansive growth of the vessel or heart lumen in response to surgical damage, which is a major cause of graft failure.

  • Patent number: 5957905
    Abstract: An orifice coupling, e.g. an ostomy coupling, includes a first coupling part (10) securable to a second coupling part (20) by a springy split locking ring (30). The locking ring (30) is held captive on the first coupling member (10) by lugs (13) extending radially from outside the locking ring and which enable the locking ring (30) to engage the second coupling member (20) substantially continuously around the periphery of the second coupling member. The coupling can be released when the ends (26,27) of the locking ring (30) are manipulated to expand the ring. The locking ring (30) may be integrally moulded with the first coupling member, and folded into an operative position on the first coupling member.

  • Patent number: 5947941
    Abstract: A two-piece ostomy appliance is disclosed, one component being a collection pouch and the other an adhesive faceplate for peristomal attachment to a patient. The two components are provided with coupling rings for mechanically and detachably joining them together. One of the rings has a bead-providing collar and a rocking wedge body as disclosed in U.S. Pat. No. 5,185,008. The other ring is of channel-shaped cross section having spaced concentric inner and outer side walls each provided with ribs positioned in direct opposition and extending into the channel along a single plane normal to the axis of that ring. In a preferred embodiment, the rib of the outer wall is interrupted to provide at least one wide notch or recess and an integral pull tab projects radially outwardly from the outer wall at the location of the notch for initiating either partial or complete separation of the rings during use of the appliance.
