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: The present disclosure relates to the field of endoscopy. Specifically, the present disclosure relates to systems and methods for en bloc resection of malignant and pre-malignant lesions and/or tumors within the gastrointestinal (GI) tract. More specifically, the present disclosure relates to systems and methods for delivering an expandable scaffold between tissue layers (e.g., between the muscularis and submucosa layers) to elevate and stabilize the lesion or tumor for fast and efficient resection.
