Diamondback 360™

Coronary Orbital Atherectomy System

Severe Calcium.
One Solution.

Diamondback 360 product
Features

Diamondback 360™ is the only atherectomy system with a diamond-coated crown that orbits 360 degrees, specifically designed to target severe calcium.

Diamondback 360™ Coronary Orbital Atherectomy System’s (OAS) unique dual mechanism of action uses differential sanding and pulsatile forces that enable simultaneous modification of both intimal and medial calcium for optimal stent delivery, expansion, and apposition in severely calcified lesions. One device treats eccentric, concentric, and nodular calcium.1-6

Diamondback 360™ OAS has a Unique Dual Mechanism of Action Design

One device reduces intimal calcium and fractures medial calcium. Differential sanding and pulsatile forces enable simultaneous modification of both intimal and medial calcium for optimal stent delivery, expansion, and apposition in severely calcified lesions.1-4

      • Heavily Stenosed Lesions
        Crossed >99% of lesions with <2% pre-dilatation in the ORBIT II study.1,10
      • Nodular Lesions
        Effectively treats nodular calcification.5,6
      • Ostial Lesions
        Safely treats ostial lesions.11-13
