    摘要： A medical device for guiding through anatomy, such as a catheter or guidewire, with a tubular body that has been slotted to enhance bending flexibility, and a polymer liner with an anti-collapsing structure, and a method of making a medical device with a kink-resistant corrugated tubular member and an anti-collapsing structure. Anti collapsing structures may be helical or annular, and may be wire, such as ribbon wire, grooves in the liner, corrugations, or a braid. Liners may be bonded to the anti-collapsing structure, or may have two layers, with the anti-collapsing structure between the layers. Corrugations may be formed between sections of the anti-collapsing ‘structure with heat, pressure, stretching, compression, a mold, or a combination thereof, and may extend inward or outward. Shape or wall thickness may vary along the length to provide a varying bending stiffness. Slots may be formed in groups of two, three, or more, and adjacent groups may be rotated about the axis forming a helical pattern.

    摘要： A combustion device for providing a stream of combustion products. In particular, there is a combustion device, utilizing micro-sized combustion tubes, that can 1) control firing profiles of an array of combustion tubes, 2) control acoustics generated thereby, and 3) provide an exhaust gas for actuating an attached device, like a piston. The array of combustion tubes is individually controlled. Wherein the array of tubes comprises either uniformly dimensioned tubes or is formed of a variety of dimensions, like length and diameter, which are arranged in selected patterns. There can be either a single ignition point at an end of the combustion tubes, or a multiple of ignition points positioned along the interior length of the tubes. There is also a combustion sequence that self extinguishing after burning all of the fuel in the combustion tube at the end of each cycle.

    摘要： Apparatus for injecting fluids into the walls of blood vessels, body cavities, and the like, includes a plurality of laterally flexible needles disposed in a catheter for exit either out the distal end of the catheter or the catheter or through corresponding side openings in the catheter. In the latter case, the terminal ends of the needles would be curved laterally, with each terminal end being positioned in a respective side opening so that when the needles were moved forwardly in the catheter, the terminal ends of the needles would move laterally out the respective openings to pierce a vessel or cavity wall adjacent to which the catheter was positioned. Hilts positioned near the terminal ends of the needles serve to control the depth of penetration of the needles.

    摘要： A volumetric pump for administering intravenous fluids to a patient comprises a housing having an elongate cavity therein with an open and a closed end. A resilient sheet of material having two branched portions which form a centrally-located aperture is disposed over the open end of the housing. A pump shaft is slidably disposed through the aperture such that one branched portion toward the cavity and the other branched portion extends away from the housing such that a sphincter seal is formed about the shaft. An inlet conduit leading from a fluid source such as an IV bag passes through the housing into the cavity near one end thereof, and an outlet conduit leading to a fluid sink such as a patient passes through the housing from the cavity near the other end thereof. The shaft is driven back and forth in reciprocating motion, inwardly and outwardly of the cavity, to alternately produce a positive pressure forcing fluid out of the outlet conduit to the fluid sink, and a negative pressure forcing fluid from the fluid source through the inlet conduit.
