Stent Securement – Dislodgement Force: Test Method Description

Measure and record forces required to dislodge a balloon-expandable stent from its delivery system under clinically relevant conditions.

Forward Motion Dislodgement (Lesion-type test) : Advancing a stent delivery system across a tight lesion could result in stent dislodgement.

Reverse Motion Dislodgement (Guide-type test) : Withdrawing a stent (un-deployed) delivery system into a guiding catheter, arterial sheath, or hemostasis valve could result in stent dislodgement.

Worst case stent securement configuration is used for this test.
