Y Valve

The Y Valve is a critical procedural accessory designed to serve as a stable, multifunctional hub at the proximal end of guiding catheters or sheaths. It integrates three essential functions—device introduction, hemostasis, and accessory port access—into a single, optimized device. Its advanced design directly addresses key clinical needs: precise device manipulation, maintenance of a large working channel, and secure, easy-to-manage hemostasis, thereby streamlining workflow and contributing to procedural success.

1. Enhanced Torque Response & Control

The valve's core design incorporates a specialized rotating hemostatic valve (RHV) mechanism engineered for superior mechanical feedback.

• 1:1 Torque Transmission: The low-friction seal and optimized bearing surfaces ensure direct, accurate transmission of rotational force from the operator's hand to the guidewire or microcatheter tip, minimizing whipping or lag.

• Precise Device Manipulation: This enhanced response is critical for navigating tortuous anatomy, crossing challenging lesions, or achieving precise device positioning, particularly in neurovascular, coronary, or complex peripheral interventions.

• Tactile Feedback: The smooth yet responsive rotation provides the operator with improved tactile sensation, allowing for finer adjustments and more confident control.

2. Maximized Lumen Diameter for Unimpeded Access

Maintaining the largest possible functional inner diameter is paramount for the simultaneous use of multiple devices.

• Full Lumen Preservation: The valve's internal architecture is designed to minimize flow obstruction and step-down transitions, preserving the native inner diameter of the connected guiding catheter or sheath.

• Facilitates Complex Device Delivery: This allows for the unimpeded passage and exchange of multiple microcatheters, stent delivery systems, coils, or other therapeutic accessories without compromising performance or requiring upsizing of the primary guide.

• Enhanced Contrast Flow: The optimized lumen ensures efficient contrast media injection for high-quality angiography without significant pressure damping.

3. Superior Hemostatic Seal with Intuitive Handling

A reliable and easily adjustable hemostatic mechanism is fundamental to procedural safety and operator convenience.

• Reliable Seal Integrity: Utilizing a proprietary compressible seal technology (e.g., a polymer gasket or diaphragm), the valve maintains a robust, fluid-tight seal around a wide range of device diameters (from small guidewires to larger microcatheters), effectively preventing blood loss and air embolism.

• Intuitive, Single-Handed Adjustment: The rotating hemostatic cap features an ergonomic, textured design that allows for secure, single-handed tightening or loosening. This enables rapid device exchanges and immediate hemostasis adjustment without disrupting the operator's focus.

• Durable, Leak-Resistant Performance: The seal material and mechanism are engineered for durability, maintaining integrity throughout lengthy procedures and across multiple device exchanges, ensuring consistent performance from start to finish.
