The NuCLEUS-X™ catheter is a coaxial catheter for use in Percutaneous Transluminal Valvuloplasty (PTV) of the Pulmonary Valve. The outer body is made of polymeric tubing, and the inner tubing is comprised of a multi-layer extrusion of polyamide (Vestamid PA12) that surrounds a braid of 304 LV Stainless Steel. The catheter features a molded proximal end bifurcate with two distinct luminal passages. The inflation lumen terminates into a distally mounted balloon made of polyamide. The balloon is designed with a waist formed into the middle of the balloon to allow accurate balloon placement. Upon reaching a specified pressure, the waist will expand to 90% of the rated balloon diameter. The distal lumen terminates at the tip of the catheter and will accept the passage of the 0.035” guidewire.
