  • Publication number: 20240148253
    Abstract: A catheter device for crossing occlusions includes an elongate body, a central lumen extending within the elongate body from the proximal end to the distal end, a rotatable tip at the distal end of the elongate body, and an OCT imaging sensor. The rotatable tip is configured to rotate relative to the elongate body. The OCT imaging sensor includes an optical fiber coupled with the rotatable tip and configured to rotate therewith. A distal end of the elongate body includes one or more markers configured to occlude the OCT imaging sensor as it rotates. A fixed jog in the elongate body proximal to the distal end of the catheter positions the distal end of the catheter at an angle relative to the region of the catheter proximal to the fixed jog and is aligned with the one or more markers on the elongate body.

  • Patent number: 5247650
    Abstract: A method and apparatus are disclosed which allows a plurality of dissimilar simulation systems to act in a cooperative manner such that they may act to provide a single overall simulation of a system. The system to be simulated is partitioned into these simulation systems and subsequently these systems are networked and synchronized. This interaction of these dissimilar simulation systems is accomplished by a simulation tool which allows a simulation system to route messages to other systems, synchronizes the operation of all simulation systems, allows partitioning elements to be stored and downloaded to these systems, and allows each simulation system to utilize its own native programming language during the creation of the single system simulation associated therewith.

  • Patent number: 4959466
    Abstract: Partially esterified oligosaccharides and polysaccharides (PEPs) of the formula [P--O--R).sub.x ].sub.n, where P is a polysaccharide having n=3-50 (preferably 3-10) C.sub.4 -C.sub.8 saccharide units, y is 0-4 (preferably 1 or 2), R is H or a C.sub.3 -C.sub.28 acyl group, and x is the degree of esterification ranging from 1-80 percent. The PEPs are used as indigestible fat substitutes (fat mimetics). They have non-caloric food values, with good organoleptic characteristics, are substantially resistant to intestinal absorption and do not appreciably hydrolyze in the digestive tract. Suitable polysaccharides are preferably selected from xanthan gum, guar gum, gum arabic, aliginates, cellulose hydrolysis products, hydroxypropyl cellulose, starch hydrolysis products, casein, Karaya gum and pectin. C.sub.5 and C.sub.6 oligosaccharides of n=3-10 units are preferred. The polysaccharides are transesterified with fatty acid methyl esters to create PEPs of a degree of esterification determined for each polysaccharide.
