Abstract: A thrombectomy apparatus for removing a clot from a vessel includes a catheter defining a lumen extending proximally from a distal end. A funnel is secured to the distal end and extends distally therefrom, the funnel includes a braided inner layer and a braided outer layer, the braided outer layer folded over the braided inner layer and adapted to constrain the braided inner layer. A tractor is adapted to extend over an 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. A puller 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.
