Medical device with tail(s) for assisting flow of urine

InactiveUS6849069B1Decrease patient discomfortDecreases patient discomfortUrinary bladderStentsInsertion stentLeft ureter
A ureteral stent for assisting movement of urine along a patient's ureter and into the patient's bladder. The stent includes an elongated tubular segment extending toward the bladder from a kidney end region for placement in the renal cavity to a bladder end region. A central lumen connects at least one opening at the first end region to at least one opening in the bladder end region. Thin flexible tail(s) are attached to the bladder end region of the tubular segment at a point outside the bladder so as to receive urine from the opening in the bladder end region of the tubular segment and to transport urine from there across the ureter / bladder junction and into the bladder. The tails include an elongated external urine-transport surface sized and configured to transport urine along the ureter. The urine transporting surface(s) are sized and configured to extend along at least part of the ureter, across the ureter / bladder junction, and from there into the bladder.

Chemically stabilized beta-cristobalite and ceramic bodies comprising same

A method for rigidifying a fiber-based paper substrate for use in the exhaust system of a combustion device. In the method, a green ceramic fiber-based paper substrate is impregnated with an impregnating dispersion. The impregnated substrate is then dried, calcined and fired to form a rigidified substrate that is suitable for use in the exhaust system of a combustion device. This rigidification process is performed at least once and, preferably, two or more times. The green paper substrate comprises two or more sheets of green ceramic fiber-based paper, with at least one creased sheet and another sheet being a laminated together to form a plurality of tubular channels. The rigidified substrate comprises refractory ceramic fibers in the form of a ceramic fiber-based paper and agglomerates of ceramic particles. The ceramic particle agglomerates are bonded to and disposed so as to thereby bond together the refractory ceramic fibers at spaced locations along and at intersections of the refractory ceramic fibers so that the refractory ceramic fibers retain much of their original flexibility while in the paper.

The upright portion has projections with substantially semi-cylindrical outer surfaces at its ends. Correspondingly shaped recesses are also provided. At a femal end, the base portion includes a nose. The surface of the nose is a surface of rotation of the profile of the base portion. At the male end, the base portion includes a correspondingly shaped cavity. The first and second projections and the nose are provided with bores. When the female end of the barrier section is brought up to a male end of a similar, adjacent barrier section, the projections mate with one another and the nose is received in the cavity of the adjacent barrier section. A hinge pin may then be passed through the bores for allowing one barrier section to be articulated to an adjacent barrier section with the joint between the two portions of adjacent barrier sections presenting an essentially smooth profile irrespective of the angle between the two adjacent barrier sections.

Expandable sealing mechanism

A sealing assembly has an expansion band having an arcuate band portion and a pair of threaded end portions formed at opposing ends of the arcuate band, in which the arcuate band and threaded end portions are monolithically formed as a single piece. Fixed within respective threaded end portions are a pair of oppositely threaded nuts adapted to receive a bolt having correspondingly oppositely threaded ends. Rotation of the bolt causes the threaded end portions to be simultaneously driven apart or drawn toward one another (depending on the rotation direction of the bolt) to thereby expand or contract the overall outer profile of the arcuate band portion. The monolithically formed expansion band may be made of an inexpensive, non-rusting material such as nylon 66, and glass fibers and / or additives may be employed to impart strength and flexibility.

Multi-beam laser spot welding of coated steels

A method of laser spot welding a workpiece stack-up (10) that includes at least two overlapping steel workpieces (12, 14, 150) is disclosed. The method includes directing a plurality of laser beams (24, 24′, 24″) at the top surface (20) of the workpiece stack-up to create a molten steel weld pool (92) that penetrates into the stack-up. The molten steel weld pool is then grown to penetrate further into the stack-up by increasing an overall combined irradiance of the laser beams while reducing the total projected sectional area (88) of the laser beams at a plane of the top surface of the workpiece stack-up. Increasing the overall combined irradiance of the laser beams may be accomplished by moving the focal points (66, 66′, 66″) of the laser beams closer to the top surface or by reducing the mean angle of incidence (86) of the laser beams so as to reduce the eccentricity of the individual projected sectional areas of the laser beams.
