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. In some examples, a slider mechanism or rotating knob located on one of the proximal luers can be used to actuate the relative motion.
