摘要：
Systems and methods for a multi-layered peel-away sheath assembly for insertion of a blood pump 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. The first layer material and the 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. The peel-away lines are formed of inner, outer notches, or both. The sheath hub also includes a discontinuity to allow the sheath hub to peel-away.
