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.
