Patent number: 8784441Abstract: Embolectomy catheters, rapid exchange microcatheters, systems and methods for removing clots or other obstructive matter (e.g., thrombus, thromboemboli, embolic fragments of atherosclerotic plaque, foreign objects, etc.) from blood vessels. This invention is particularly useable for percutaneous removal of thromboemboli or other obstructive matter from small blood vessels of the brain, during an evolving stroke or period of cerebral ischemia. In some embodiments, the embolectomy catheters of this invention are advanceable with or over a guidewire which has been pre-inserted through or around the clot. Also, in some embodiments, the embolectomy catheters include clot removal devices which are deployable from the catheter after the catheter has been advanced at least partially through the clot. The clot removal device may include a deployable wire nest that is designed to prevent a blood clot from passing therethrough.Type: GrantFiled: February 19, 2010Date of Patent: July 22, 2014Assignee: MicroVention, Inc.Inventors: Robert F. Rosenbluth, George R. Green, Jr., Brian J. Cox, Thomas R. Sternweiler, Sean L. Chow, Richard R. Monetti, Teresa L. Halverson, Maricela D. Walker, Robert Pecor

Patent number: 6375669Abstract: Apparatus for vascular embolization, deployable through a microcatheter, includes a flexible, elongate deployment tube dimensioned for insertion through the microcatheter, and a filamentous embolic device releasably attached to the distal end of the tube. The embolic device is controllably transformable from a soft, compliant state to a rigid or semi-rigid state. The embolic device may include a polymeric material that is transformable by contact with vascular blood or with a liquid that is cooler than vascular blood, or it may include a metallic material that is transformable by electrolytic corrosion. The embolic device may be a continuous filamentous polymeric extrusion; an elongate microcoil filled with polymeric material; an elongate, multi-segmented chain including polymeric interconnecting portions; or an elongate chain of metal segments that are fused together by electrolytic corrosion.Type: GrantFiled: December 23, 1999Date of Patent: April 23, 2002Assignee: MicroVention, Inc.Inventors: Robert F.

Patent number: 4983222Abstract: A method for decontaminating PCB containing transformers. The transformer is initially cleaned using a vapor degreasing solvent. The internal parts are removed and given a second cleaning which combines vapor degreasing with mechanical tumbling. The transformer and its parts are cleaned to less than 10 .mu.g/100 cm.sup.2 PCB. These cleaned parts are reclaimed rather than disposed of as toxic waste.Type: GrantFiled: April 14, 1988Date of Patent: January 8, 1991Assignee: Union Carbide Chemicals and Plastics Company Inc.Inventors: Gregory R. Green, George R. Green
