InWIRE 0.014” & 0.018” CTO Guidewire
A range of high-performance guidewires offering durable nitinol or stainless cores, hydrophilic coatings, and multiple tip shapes for crossing calcified or complex coronary & peripheral lesions.
InWIRE® is a recanalization guidewire system specifically crafted to facilitate the insertion of catheters and interventional medical devices in challenging vascular lesions, particularly in cases of chronic total occlusion (CTO). By combining hydrophilic coating, torque control, and a flat, malleable tip, InWIRE aims to enhance steerability, pushability, and precision in complex anatomical pathways.
Flat, Malleable Tip
- Customizable Shaping: The tip can be bent or angled to navigate tortuous vessels and tight occlusions.
- Tactile Feedback: Physicians experience improved tip response, aiding in precise lesion crossing.
Hydrophilic Polymer Coating
- Low Friction: Minimizes resistance in heavily calcified or fibrotic lesions, reducing the risk of wire-induced trauma.
- Enhanced Trackability: Facilitates smooth passage through narrow segments, supporting faster lesion penetration and fewer wire exchanges.
Radiopaque Tip
- Clear Fluoroscopic Visualization: Real-time visibility of the wire tip promotes safer lesion navigation and helps avoid dissection planes or perforation.
- Accurate Positioning: Confidence in wire tip location reduces procedural guesswork and shortens total procedure time.
Torque Capability
- 360-Degree Steerability: Balanced torque transfer from the proximal shaft ensures stable manipulation in CTO recanalization.
- Reduced Wire Buckling: Construction designed to withstand rotational forces, preserving wire integrity during prolonged procedures.
Multiple Diameter Options
- 0.014” & 0.018”: Addresses various interventional needs, from coronary vessels (common for 0.014”) to peripheral arteries (common for 0.018”).
