Diamondback 360

The Diamondback 360 (Abbott) is a peripheral orbital atherectomy system designed to address calcified lesions in arteries, particularly in the legs (peripheral artery disease). Its key strengths and USPs center on:   Orbital Atherectomy: It utilizes a diamond-coated crown that rotates, ablating plaque while minimizing damage to healthy tissue. This rotational mechanism is a core differentiator.   Differential Cutting: The crown's design allows for differential cutting, meaning it preferentially targets harder, calcified plaque while gliding over softer tissue. Calcium Modification: It effectively modifies calcified plaque, improving vessel compliance and preparing the vessel for subsequent interventions like stent placement. Reduced Distal Embolization: The system aims to minimize the risk of debris breaking off and traveling downstream (distal embolization), a common concern in plaque removal procedures. Versatility: It can be used in a variety of lesion types and locations within the peripheral vasculature.
