DISRUPT PAD II

Core lab adjudicated, long-term, multi-center study exclusively enrolling heavily calcified lesions building upon DISRUPT PAD I. Designed to assess the safety and performance of Shockwave IVL as stand-alone treatment among eight centers in Europe and New Zealand in 2015.

Balloon Sizing and Therapeutic Overlap Enables Optimal Energy Delivery to Peripheral Calcified Lesions 

Illustration showing optimal vs. undersized balloon sizing and coverage. The left side depicts an 'Optimal' balloon fully apposed to the vessel wall, improving energy transfer, while an 'Undersized' balloon shows gaps, reducing efficiency.
