    Abstract: Thrombectomy catheter and high-pressure protection systems for protecting a catheter shaft from high-pressure fluid jets. 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 fluid supply tube includes jet orifices for expelling fluid jets from the high-pressure fluid supply tube within the catheter lumen. Reinforcement members are disposed within the catheter lumen such that fluid jets expelled from the jet orifices impinge against the reinforcement members.

    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.
