A61F 2/84

US Classification:

623 111, 604 9601, 6041031, 604509

Abstract:

A catheter configured for performing reperfusion by alternatively occluding a vessel so as to prevent fluid flow and removing that occlusion to allow fluid flow is described. A first catheter includes an outer member and a retractable valve to allow and prevent fluid flow in the vessel. A second catheter includes a sheathed expansion member that can be deployed and recaptured to prevent and allow, respectively, fluid flow. A third catheter includes an angioplasty balloon to open a vessel occlusion, in which an occlusion balloon is used to allow and disallow fluid flow. A fourth catheter includes an expandable member for providing mechanical plunging action to urge thrombotic material to a more distal location. A fifth catheter includes an accessory catheter that can be used to perform reperfusion with another catheter. A sixth catheter includes an inner balloon within an outer balloon configured to perform reperfusion.

International Classification:

A61F 2/82

US Classification:

623 115

Abstract:

Stent scaffolds that include a polymeric structure or structures bonded to the scaffold and extending along their length are disclosed. The polymeric structure extends across some or all of the gaps in struts along the length of the scaffold. Segmented scaffolds are also disclosed that include two or more axial segments arranged end to end not connected by link struts.

Appl. No.:

7/907751

Inventors:

Syed M. Ahmed - Riverside CA

International Classification:

B01L 300

US Classification:

422102

Abstract:

A blood sample/fluid system includes a pair of tubes formed of identically shaped concentric cylinders, each closed at one end and open at the other end and having different diameters enabling the reduced diameter tube to be positioned in the enlarged diameter tube. A locking ring is positioned around the outer surface of the reduced diameter tube to provide a spacer and seal for the enlarged diameter tube. An identifying label is positioned on the outer surface of the enlarged diameter tube for providing identity for both tubes when the tubes are engaged and for the enlarged diameter tube when the reduced diameter tube is removed from the enlarged diameter tube.

International Classification:

C10B 57/02
C10B 53/00
C10B 57/06

Abstract:

The present technology is generally directed to providing beds of coking material to charge a coking oven. In various embodiments, a quantity of first particulate material, having a first particulate size and bulk density, is combined with a second particulate material, having a second particulate size and bulk density, to define a multi-modal bed of coking material. The multi-modal bed of coking material exhibits an optimized bulk density that is greater than an ideal bulk density predicted by a linear combination of the bulk densities of the individual materials.
