Abstract: A catheter for use in vasculature or other body lumen includes a fluid injection bypass tube, leading to a elastically compressible pump bulb. Upon compression of the pump bulb, fluid such as contrast solution is injected through a one-way valve, into the catheter manifold lumen, and ultimately to the distal end of the catheter lumen, and into the patient vasculature. The one-way valve between the pump bulb and the catheter lumen has a threshold pressure to prevent unintended aspiration of fluid from the pump bulb during aspiration of fluid from the catheter itself.

Abstract: A disposable plastic lid is formed with a vent hole. A filter formed of a hydrophobic material such as polytetrafluoraethylene is mounted over the vent hole. The pore size of the filter material is selected to allow for the free passage of air and to inhibit or block the passage of liquids such as water.

Abstract: The present invention provides a compression device for selectively applying compressive force to a localized area of interest on the surface of a body that is readily positioned and fastened in place. The device includes a resilient compressible element positioned on a relatively rigid member associated with a clamping frame that at least partially surrounds a limb or other body area of interest. An adjustable closure means is provided for adjustably completing the clamp arrangement to completely enclose said bodily region of interest in a manner that enables the compressible element to be applied to the precise site of interest. The adjustable closure element permits accommodating bodily parts such as limbs of various size and facilitates adjustment of the compressive pressure applied. The device may take a variety of embodiment forms.

Abstract: A method and apparatus for manufacturing a garment which is three dimensionally molded. The garment in the form of opposing sheets of fabric are fed from bolts of fabric to a molding station wherein a male mold section is provided in the shape of the three dimensional garment desired. A pair of opposing female mold sections close onto the male mold section sandwiching the sheets of fabric into the mold cavities. Heat is applied to mold the fabric sheets into the three dimensional garment. Simultaneously, an ultrasonic seamer cuts and bonds the periphery of the material around the mold. The mold cavity is then opened, portions of the mold are separated and the garment is then lifted off the male mold section.
