  • Patent number: 7947033
    Abstract: Wound fluid blood detection systems and methods are described that are operable in conjunction with reduced pressure wound treatment (RPWT) systems, as well as ancillary therapy and monitoring systems applied concurrently with RPWT systems. The blood detection monitor operates by optically characterizing the content of wound fluids to the extent of identifying percentage blood content. This identification relies upon the transmission of select wavelengths of light across a volume of wound fluid to a photo detector (connected to signal processing instrumentation) capable of quantifying the absorption characteristics of the fluid. The detection components may be implemented in conjunction with either a fluid flow conduit (i.e. the reduced pressure tubing directing fluid away from the wound dressing) or more directly in association with the materials that comprise the wound dressing positioned within the wound bed itself.

  • Patent number: 6659937
    Abstract: A bladder access device is disclosed that incorporates a load port and a valve connected to each other by way of a series of tubes. The valve is a four piece elliptical ring closed by a locking mechanism. The inner major axis portion of the elliptical ring has two inflatable cuffs. When fluid is injected into a self sealing and leakproof load port, the fluid flows through the series of tubes into the inflatable cuffs of the valve thus expanding them. This allows the elliptical ring to be placed around a patient's bladder and upon inflation of the inflatable cuffs, the valve closes onto the bladder allowing for continence. During this state of inflation, access can be made to the bladder by compressing the valve with two fingers. The valve closes automatically when released. The present device can be used as a closure control valve for other internal organs as well.

    Abstract: A device for the percutaneous transluminal repair of septal defects is disclosed. The device comprises first and second expandable occluders fastened to each other, each occluder including a framework having a central hub with elongated struts radiating therefrom. The struts are constructed such that they have a resistance to fatigue that exceeds the maximum fatigue stresses to which the struts will be subjected over a prolonged period in vivo. As such, the device exhibits a significantly decreased likelihood of metal fatigue failures after prolonged exposure in vivo.

  • Patent number: 4981465
    Abstract: A disposable closure for an artificial or an incontinent natural intestinal opening has a porous, elastic, air-filled body which in a state not influenced by external compressive forces is a substantially cylindrical, conical or bell-shaped structure having a cross-sectional area, measured halfway between its ends, of at least the double of the cross-sectional area of the intestinal duct for which it is intended. When supplied by the manufacturer, this elastic body is compressed to a substantially cylindrical shape having a cross-sectional area as or slightly below that of the intestinal duct in question. The elastic body is maintained in that compressed state by a moisture- and/or heat sensitive material, the shape-maintaining effect of which is rapidly eliminated upon contact with the moisture content of the intestine and/or the heat of the human body. The elastic body may for instance be made of a foam plastic and the shape-maintaining material may for instance be a cover of polyvinyl alcohol.

  • Patent number: 4941869
    Abstract: An ostomy pouch having a plug for the stoma and a pouch to collect natural discharges. The plug stops the natural discharges from collecting in the pouch. The pouch is employed to catch any discharges that might leak through the plug and to form a reservoir when the plug is dislodged. Such a reservoir is especially required when one is in training for the use of the stoma plug. The pouch has an openable top through which the user can reach to remove the stoma plug so that the contents of the colon can be drained into the pouch. The bottom of the pouch is also openable, allowing the user, when sitting on a water closet, to drain the pouch into the toilet without undressing any more than would a person without a colostomy. After discharge of the pouch, the bottom drain can be resealed, the plug placed back into the stoma, and the top of the pouch closed.The pouch is detachably mounted on a person's body. As confidence and control in the use of the ostomy plug is developed, the pouch can be used less and less.

  • Patent number: 4850953
    Abstract: An improved gastrostomy valve by which to deliver liquid nourishment through the abdominal wall of a baby that, due to a congenital, functional, or other disability, is unable to eat normally. The gastrostomy valve is provided with an expansible membrane or balloon and a fluid circuit interconnected therewith. Fluid is provided via the fluid circuit to inflate the balloon which, in turn, causes the membrane to roll towards the abdominal wall of a baby. The inflated membrane assumes a torroidal configuration which forms an efficient seal against the abdominal wall, whereby to minimize leakage and prevent an inadvertent removal of the gastrostomy valve from the abdominal cavity. The improved gastrostomy valve also includes an internally disposed feeding lumen or stem, an externally disposed fluid infusion port, and an anti-reflux check valve located therebetween.
