  • Publication number: 20210275198
    Abstract: An aspiration clot retrieval catheter to have profiled guidewire for deliverability that transitions at a proximal joint to a distal tubular section with a lumen for directing aspiration and facilitating the smooth passage of other products in performing mechanical thrombectomy procedures. The joint can have a low-profile proximal strut formed integrally with the distal tubular section and configured to interlock with a distal portion of the guidewire so that there is a smooth transition of stiffness between the guidewire and the tubular portion of the catheter to improve trackability and decrease the likelihood of kinking. The distal tubular section of the proximal joint can also have features to tailor flexibility. The tubular section can be configured to push radially outward to form a seal with an outer catheter to optimize aspiration transmission to the distal mouth of the aspiration clot retrieval catheter.

  • Publication number: 20210275197
    Abstract: A system has an outer catheter and an inner aspirating clot retrieval catheter having an expansile distal tip for flow restriction, improved aspiration efficiency, and a large mouth into which a clot or other obstructions can be retrieved. The clot retrieval catheter can have a support tube proximal of the tip. The expansile tip can be a strut framework, and a flexible, low-modulus cover is disposed around at least a portion of the tip strut framework and the proximal support tube. The distal end of the tip can be encapsulated by a low-friction elastomeric lip for atraumatic contact with the walls of a blood vessel. The tip has a collapsed delivery configuration and expands radially into a deployed configuration. The tip strut framework, support tube, and cover can all have characteristics which enhance the deliverability of the clot retrieval catheter to the target.

  • Publication number: 20210259720
    Abstract: A device for removing clot from a blood vessel includes a shaft. An expandable framework of struts is fixedly coupled to a distal region of the shaft. The struts can be radially expandable from a first to a second radially expanded state in a deployed configuration. An actuation cable can be connected to a plurality of connections of the engaging framework of struts to apply an expansion force, by the struts, as the struts are actuated by the actuation cable from the first radially expanded state to the second radially expanded state. In the first radially expanded state, a distal end of the struts is spaced a first axial distance away from the shaft, and wherein in the second radially expanded state, a distal end of the struts is spaced a second axial distance, different than the first axial distance, away from the shaft.

  • Patent number: 11051928
    Abstract: Shortly after completing a thrombectomy procedure, a temporary carotid filter can be deployed downstream of an occlusion not treated by the thrombectomy (e.g. a carotid lesion having plaque buildup), and the temporary carotid filter can remain in place during the patient's recovery period following the ischemic stroke until a procedure to treat the remaining occlusion is completed and antiplatelet therapy is administered. The temporary carotid filter can anchor in place while deployed with or without being tethered to a wire extending through the patient's Femoral Artery.

  • Publication number: 20210154433
    Abstract: A device for retrieving an obstruction in a blood vessel can have an outer sheath with a distal end, a proximal end, a proximal luer encompassing the proximal end, and an internal lumen extending proximal of the distal end and terminating within the proximal luer; and an inner funnel catheter within the outer sheath comprising an expanding distal tip, a proximal end, a distal end located at the distal tip, a proximal luer encompassing the proximal end, and an internal lumen extending proximal of the distal end and terminating at the luer. The outer sheath and inner funnel catheter can be capable of moving telescopically with respect to each other.

  • Publication number: 20210153884
    Abstract: A clot retrieval catheter can have an expansile distal tip for flow restriction/arrest and improved aspiration efficiency and a large, distal facing mouth into which clots or other obstructions can be retrieved. The tip can be formed from a distal ring of leaflets or hoops. One or more pull cables can be retracted to actuate and radially expand the expansile distal tip. The clot retrieval catheter can have a catheter shaft with flexibility-adding features proximal of the tip. The catheter shaft can be a multi-lumen configuration with a large catheter lumen for passing auxiliary devices and directing aspiration and one or more guide lumens which can route the pull cables to the leaflets or hoops of the expansile tip. A flexible, low-modulus membrane can be disposed around at least a portion of the expansile tip and catheter shaft.
