Publication number: 20240108862Abstract: Systems and methods for a multi-layered peel-away sheath assembly for insertion of a blood pump, the peel-away sheath assembly including a sheath hub and a sheath body having a proximal end that is connected to the sheath hub, and a distal end. The sheath body comprises multiple layers including a reinforcing layer. The reinforcing layer improves flexibility and kink resistance of the assembly The reinforcing layer can comprise LCP, PEBAX, stainless steel, Nitinol, or Kevlar. The reinforcing layer may be a laser-cut hypotube or a braided or coiled filament. A first layer material and a third layer material are thermoplastics, including PEBAX or TPU. The reinforcing layer has at least one discontinuity, which is aligned with peel-away lines in the sheath body to allow an operator to peel-away the assembly.

Publication number: 20240017037Abstract: A method for manufacturing a medical introducer includes placing an introducer sheath onto a mandrel, and overmolding an introducer hub onto a proximal end of the introducer sheath. The introducer sheath has one or more score lines formed on an inner surface and the mandrel has a number of surface protrusions so that when the introducer sheath is positioned on the mandrel, each of the surface protrusions contacts one of the score lines formed on the introducer sheath. The surface protrusions on the mandrel prevent plastic material from the introducer hub from contacting the score lines thereby maintaining the score lines during the overmolding.Type: ApplicationFiled: June 20, 2023Publication date: January 18, 2024Applicants: ABIOMED, Inc., Oscor, Inc.Inventors: Glen Fantuzzi, Michael Tafone, Jeffrey Drum
