    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: This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example aspiration catheter includes a catheter shaft having a proximal end region, a distal end region and a lumen extending therein. The aspiration catheter also includes a tip member having a length and a lumen extending therein, wherein the tip member is coupled to the distal end region of the catheter shaft and a guidewire shaft having a proximal end region and a distal end region. Further, the guidewire shaft extends within at least a portion of the lumen of the catheter shaft and the lumen of the tip member. Further, the distal end region of the guidewire shaft includes an interlock region and a portion of the tip member is engaged with at least a portion of the interlock region.

    Abstract: A delivery system for an occlusive implant may include a delivery sheath having a delivery lumen extending proximally from a distal end of the delivery sheath, the delivery sheath being formed from a polymeric material, and a core wire slidably disposed within the delivery lumen. The core wire may be configured to releasably engage the occlusive implant. The delivery sheath may include a circumferential ring monolithically formed therewith at the distal end of the delivery sheath and a plurality of longitudinal slots disposed proximal of the circumferential ring. An occlusive implant system may include an occlusive implant configured to shift between a delivery configuration and a deployed configuration, and the delivery system for the occlusive implant. The occlusive implant may be disposed within a distal portion of the delivery lumen in the delivery configuration.
