Abstract: Methods and apparatuses for removing material (e.g., clot) from within a body, including inverting thrombectomy apparatuses. These methods and apparatuses may include methods and apparatuses for reusing portion of the devices, method and apparatuses for loading and reloading the inverting thrombectomy apparatuses, and methods and apparatuses for improving and enhancing the ability of the inverting thrombectomy apparatuses to remove clot.

Abstract: A thrombectomy apparatus includes a funnel that is secured to a distal end of a catheter. The funnel includes a braided inner layer, a braided outer layer and a reinforcing structure disposed therebetween. The reinforcing structure includes a tubular metal member and a plurality of fingers extending distally from the tubular metal member. Each finger defines two or more pockets. Each of two or more rings extend through a pocket of each of the plurality of fingers, the pockets limiting axial movement of each of the two or more rings. A tractor is adapted to extend over the outer surface of the catheter and the funnel in an un-inverted configuration and to extend in an inverted configuration through the funnel and into the lumen. An elongate member extends through the lumen and is secured to an end of the tractor disposed within the lumen.

Abstract: A thrombectomy apparatus includes a catheter having a funnel is secured to a distal end and extending distally therefrom. The funnel includes a braided inner layer, a braided outer layer, and a reinforcing structure disposed between the braided inner layer and the braided outer layer, the reinforcing structure including a plurality of arched wires extending between the braided inner layer and the braided outer layer. A tractor is adapted to extend over the outer surface of the catheter and the funnel in an un-inverted configuration and to extend in an inverted configuration through the funnel and into the lumen, the tractor adapted to invert by rolling over the distal end of the funnel when the tractor moves proximally. An elongate member extends through the lumen and is secured to an end of the tractor disposed within the lumen.
