The Boston Scientific HORNET 14 Wire (REF H749393073002) is a high tip load coronary guidewire designed to support interventional cardiologists when navigating and penetrating challenging coronary anatomy, including chronic total occlusions (CTOs). Its dedicated construction is engineered to deliver a balance of penetration force, tactile feedback, and one-to-one torque transmission during complex percutaneous coronary interventions.

Key Features
Designed for high penetration force to address resistant or calcified lesion caps.
One-to-one torque response intended to enhance steerability in tortuous vessels.
Hydrophilic coating segment to facilitate device tracking and lesion crossing.
Stainless steel core construction supporting tip stiffness and pushability.
Tapered tip configuration intended to concentrate force at the lesion entry point.
Radiopaque distal segment to support fluoroscopic visualization.

Clinical Applications
Intended for use in percutaneous coronary intervention procedures requiring guidewire access across coronary lesions.
Commonly selected by operators for crossing attempts in chronic total occlusions and heavily fibrotic or calcified plaque.
Supports antegrade wire escalation strategies within structured CTO crossing algorithms.
May be used in conjunction with microcatheters or over-the-wire support catheters per institutional practice.
