Patent number: 9855070Abstract: A matter elimination catheter includes a catheter body extending from a catheter proximal portion to a catheter distal portion. The catheter body includes an infusion lumen, an aspiration lumen fluidly isolated from the infusion lumen, and a septum interposed between the infusion and aspiration lumens. A drive shaft is within the infusion lumen and is configured to provide rotation near the catheter distal portion. A guide wire lumen is within the drive shaft, and the infusion lumen, the drive shaft and the guide wire lumen are fluidly separated from the aspiration lumen with the septum. In one example, fluid bearings are formed between one or more of the catheter body and drive shaft or the drive shaft and a guide wire or guide wire liner when supplied with infusion fluid through the infusion lumen.Type: GrantFiled: March 6, 2015Date of Patent: January 2, 2018Assignee: Boston Scientific LimitedInventors: Michael J.
