Cardiocycle's SteerFar QuYou®—World’s Smallest (1.7F) and Most Comprehensive Controllable Microcatheter—Receives NMPA Approval

1. The world's most comprehensive specification matrix

• Outer Diameter Range: 1.7F-2.7FOffering 5 outer diameter specifications (1.7F/1.9F/2.1F/2.4F/2.7F), compatible with more devices, providing a complete access solution.

• Dual Length Design: 125cm (Radial Artery Optimized), 150cm (Femoral Artery/Long Pathway Adapted),Achieve precise access matching.

2. Smallest global outer diameter (1.7F)

• Breakthrough in passability bottleneck: 1.7F outer diameter(Approx. 0.57mm) is currently the globally available steerable microcatheterMinimum value.

1. Chronic Total Occlusion (CTO) Percutaneous Coronary Intervention

In complex CTO lesions with ambiguous proximal fibrous cap, tortuous collateral vessels, or requiring reverse CART technique, steerable microcatheters can be applied:

• Entering branch vessels

• Re-enter the True Lumen

• Delivery of guidewire in acute branch

Advantages: Reducing the need for guidewire pre-shaping, enhancing the controllability of microchannel navigation.

2. Structural Heart Interventions

Especially in the application of atrial septal puncture and left atrium navigation:

• Mitral Valve Intervention

• Left Atrial Appendage Occlusion

• Paravalvular Leak Closure

• Delivery of Steerable Sheath

Advantage: Precise alignment with the fossa ovalis or the opening of the left atrial appendage, reducing fluoroscopy time.

3. Peripheral Vascular Intervention (PVI)

• Complex occlusive lesions through the iliac artery, superficial femoral artery, or tibial artery

• Embolization procedure involving branch vessels (e.g., uterine fibroids, endoleaks)

Advantage: The deflectable tip helps bypass calcified plaques or tortuous branches.

4. Cardiac Electrophysiology Monitoring and Ablation (EP)

• For pulmonary vein isolation, atrial mapping, and ablation therapy

• Some electrophysiological catheters integrate steering control with mapping sensor functions.

Advantages: Achieve precise positioning and ensure stable contact with the endocardial surface.
