Push Efficiency/ Pushability
Utilizing MSI’s Proximal Roller System a catheter, guide wire, or other interventional device is advanced through a simulated anatomic model (torturous path) while collecting force and distance data that the product experiences with a load cell, motor encoder, and independent encoder. At the end of the torturous path, MSI’s Distal Load Cell is set in place to capture forces that the distal tip of the product exerts on the distal load cell yielding proximal force input vs distal force output. A typical Push test consists of a catheter tracked over a guide wire pushed into the distal load cell to a set force or customer specified failure mode. Examples of different failure modes include product buckle, bend, or drop in proximal or distal forces.
