Intravascular Lithotripsy
Brief summary
The FORWARD PAD IDE Study is a prospective, multi-center, single-arm investigational device exemption study, conducted to assess the safety and effectiveness of the Shockwave Medical Mini S Peripheral IVL System for the treatment of heavily calcified, stenotic peripheral arteries.
Interventions
The Shockwave Medical IVL System is intended for lithotripsy-enhanced treatment of lesions, including calcified lesions, to increase luminal diameter, allowing for further treatment (e.g. post-dilatation) in the peripheral arterial vasculature. Not for use in the coronary or cerebral vasculature.
