Abstract: Example medical devices are disclosed herein. An example aspiration catheter includes a catheter body having a proximal end region, a distal end region and a lumen extending therein. The aspiration catheter further includes an impedance sensor disposed along the distal end region of the catheter body, the impedance sensor configured to sense the impedance difference between blood and thrombus.

Abstract: Thrombectomy catheter and high-pressure systems for preventing clogging of a thrombectomy catheter. An illustrative thrombectomy catheter may comprise a catheter body including a catheter lumen extending therethrough. A high-pressure fluid supply tube extends through the catheter lumen from the catheter body proximal end region toward the catheter body distal end region. The high-pressure fluid supply tube is configured for communication with a fluid source near the catheter body proximal end region. The high-pressure supply tube includes at least one proximally projecting jet orifice for expelling at least one proximally oriented fluid jet from said high-pressure fluid supply tube in a generally proximal direction and at least one distally projecting jet orifice for expelling at least one distally oriented fluid jet from said high-pressure fluid supply tube in a generally distal direction. The catheter body further includes an entrainment inflow orifice positioned along the catheter distal portion.

Abstract: Thrombectomy catheter systems, accessory devices, and methods for making and using such devices are disclosed. An example thrombectomy system may include a catheter shaft having a proximal portion, a distal portion, and a lumen extending at least partially through the catheter shaft. A high pressure tube may be disposed within the lumen. The high pressure tube may be designed for communication with a fluid source. A fluid jet emanator may be coupled to the high pressure tube. The fluid jet emanator may have at least one jet orifice. The catheter shaft may include a first orifice disposed proximally of a distal end of the catheter shaft and a second orifice disposed proximally of the first orifice. An accessory device may be disposed within the lumen. The accessory device may include a helical distal region.

Abstract: Thrombectomy catheter and pump assemblies for controlling a flow of effluent from a thrombectomy catheter. An illustrative assembly may a thrombectomy catheter, a pump, a connection manifold assembly positioned between the thrombectomy catheter and the pump, an effluent return tube fluidly coupled to the thrombectomy catheter and the connection manifold assembly, an effluent collection bag, an effluent waste tube fluidly coupled to the connection manifold assembly and the effluent waste bag, and a spool valve positioned in line with the effluent waste tube.
