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.
