Mechanical tests. The NHLBI passive guidewire (black) and the Glidewire (red) showed comparable mechanical characteristics. a Force required to deflect the tip to a selected bend angle. b Pushability test depicts the force to advance the guidewire through a vascular phantom. c Torquability inside the vascular phantom indicates torque ratio (number of rotations observed at the distal end of the guidewire per rotation applied at the proximal end) of the two guidewires
