Publication number: 20080086110Abstract: Aspiration catheters generally comprise a tube or shaft with an aspiration opening at or near its distal end and a suction device that is at or near the proximal end of the catheter. An aspiration lumen extends from the suction device to the aspiration opening. The aspiration catheter can be associated with an extendable device such that their functions can be combined advantageously. The extendable device can function as a treatment structure and/or as a flow modifier. A treatment structure can be used to expand a constriction in a vessel or to deliver a treatment element into the vessel. A flow modifier generally controls the flow to decrease flow in the vicinity of the aspiration opening to improve the efficiency of the aspiration. Various relationships between the extendable structure and the aspiration catheter are described.Type: ApplicationFiled: November 21, 2005Publication date: April 10, 2008Inventors: Jason Galdonik, Peter Dardi, Matthew Ogle, Gregory Boldenow, Edward Anderson

Publication number: 20070060911Abstract: Thrombectomy catheters are presented that have curved tip portions. A suction lumen extends from at or near the proximal end of the catheter to a suction port at or near the tip portion of the catheter. The curves of the thrombectomy catheter can be selected to place a suction port at or near a vessel wall for the more effective removal of thrombus resulting from directing the suction in the direction of the thrombus. In some embodiments, the tip portion of the catheter can be transitioned from a first configuration for delivery of the catheter into the vessel to a second more curved configuration with a desired design for application of suction. The catheter can be moved in a circumferential and/or lateral direction to cover selected portions of the inner vessel wall. In some embodiments, a partially occlusive structure can be used to reduce and/or redirect flow within the vessel to improve performance of the thrombectomy.Type: ApplicationFiled: April 21, 2006Publication date: March 15, 2007Inventors: Mark Webster, Jason Galdonik, Matthew Ogle
