ROTATING JET FOR THROMBECTOMY CATHETER

Abstract: systems and methods including a jet rotator (e.g., a saline jet rotator) to aspirate a thrombus or thrombotic material. the jet rotator rotates when the pressurized fluid (e.g., saline) is allowed to flow through the supply lumen. the jet rotator includes a proximal plenum that is configured to allow injection of the pressurized fluid into the jet rotator when the pressurized fluid flows through the supply lumen. the jet rotator includes a distal plenum and one or more pressurized fluid channels. the channels allow the pressurized fluid to flow from the proximal plenum to the distal plenum. the jet rotator includes a jet orifice that is configured to allow the pressurized fluid to flow from the distal plenum into the aspiration lumen. either the jet orifice, the channels, or other features of the jet rotator provide for rotation of the jet rotator relative to the aspiration lumen during use.
