  • Patent number: 4752286
    Abstract: This invention provides an improvement in a method of surgically treating an esophageal varix utilizing an endoscope wherein air under pressure is directed to expand a patient's esophagus and wherein the varix is located, punctured and injected with a sclerosing material. The subject improvement involves directing a dual-lumen balloon tube through the patient's esophagus, the dual-lumen balloon tube including a primary suction lumen and a secondary inflation lumen. After the vatix is located, punctured and injected with sclerosing material, the balloon tube is partially withdrawn to position the balloon adjacent the varix and fluid under pressure is directed through the secondary lumen to inflate the balloon to thereby compress the varix to assist in stemming the flow of blood therefrom. Suction is then applied to the primary lumen to relieve pressure in the patient's stomach.

  • Patent number: 4723956
    Abstract: In a container defining a flexible wall, means for sealingly receiving a puncture member through the wall which comprises an insert member positioned within the container. The insert member defines an aperture for sealingly receiving the puncture member after penetration through the wall. The aperture provides flow communication between the container interior and a puncture member received in the aperture. Thus, access may be provided to a container which has no conventional tubular port carried on its exterior. Optionally, tape means may be removably adhered to the flexible wall so that removal of the tape means exposes a clean surface through which the puncture member can penetrate.

  • Patent number: 4714460
    Abstract: Catheter feedback methods and systems are disclosed for optimizing the infusion of a drug, such as a chemotherapeutic agent via retrograde perfusion through the venous side of the vascular network to a selectively determined portion of a solid tumor. Monitoring and regulatory capability are provided for controlling the outflow of the drug and thereby for controlling the dose rate, the duration of exposure of the drug, the leakage factor, and the level of systemic toxicity, all critical factors in the successful treatment of solid tumors. A feedback loop for practicing the method comprises two concentric balloon catheters capable of extensive maneuvering and selective placement within the venous drainage of the vascular system, creating a third in-vivo space for repeated perfusion of the selected portion of a diseased organ as often as desired, providing maximum exposure of the chemotherapy to the tumor with minimum exposure to any other portions of the patient's body.

  • Patent number: 4704113
    Abstract: A dressing comprising a textile-like nonwoven fabric characterized in that the fibers comprise a blend of fibers including a percentage (preferably from about 15 to about 60 percent) of thermoplastic fibers, and the fabric is compacted (preferably micro-creped at an overfeed not less than 10 percent and typically in the range of about 20 to about 30 percent and at a drum temperature of greater than about 250 degrees F.) subsequent to hydro-entangling the fibers. prior to compacting, the fabric typically has a weight in the range of about 20 to 60 grams per square yard. After compacting, the fabric has an absorptive capacity and a liquid transfer both of which are greater than the absorptive capacity and liquid transfer of a hydro-entangled fabric of the same weight and fiber blend which has not been compacted.

  • Patent number: 4699619
    Abstract: An absorbent structure designed for use in absorbent pads such as diapers is disclosed. According to a first aspect of the invention, absorbent pads are provided which comprise at least two layers of cellulosic fibers (fluff) of different densities or average pore size ranges. When the absorbent structure is incorporated in a diaper, the lower density element extends to the full length and width dimensions of the normal absorbent component of the diaper. The higher density element lies beneath at least a portion of the lower density element. According to various embodiments of the present invention, it can run as a strip from the target zone to the back waist of a diaper, it can run along a central portion extending the whole length of the diaper, or it can underlie the entirety of the lower density element.
