    Abstract: 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. The peel-away lines are formed of inner notches, outer notches, or both. The sheath hub also includes a discontinuity to allow the sheath hub to peel-away.

    CPC classification number: A61M29/02

    Abstract: A device and method are provided for minimizing and/or preventing limb ischemia, such as when a medical device inserted into a patient’s vasculature occludes the vessel. The device may include a tubular member and one or more expandable features having metal wires disposed around the tubular member, the one or more wires disposed around the tubular member configured to be expanded at a target site, allowing blood to flow around and past any potentially occluding medical device.

    Abstract: The present disclosure is drawn to an access device that includes a cannula with a joint lumen therethrough, and a hub coupled to a proximal end of the cannula. The hub includes at least two arms. The first arm may have a first lumen and a first hemostatic valve, the first lumen operably connected to the joint lumen, where the first lumen and the first hemostatic valve are configured for passage of a medical device, and the second arm may be coupled to the first arm and have a second lumen, the second lumen operable connected to the joint lumen, the second arm configured to be operably coupled to an external medical device, such as an extracorporeal membrane oxygenation (ECMO) device.
