Custom Silicone Hemostasis Valve for Medical Device | Hopewell

Hopewell‘s silicone hemostasis valve is a precision-molded sealing component designed to prevent blood leakage while allowing guidewires, catheters, and other interventional devices to pass smoothly through vascular access systems. It is an essential component in introducer sheaths, Y-connectors, and other fluid management devices used in diagnostic and interventional procedures.

Manufactured from high-performance medical-grade liquid silicone rubber (LSR), this valve provides reliable hemostatic sealing, excellent elasticity, and long-term durability for demanding clinical applications. The self-sealing design automatically conforms around inserted instruments of varying diameters, maintaining a fluid-tight seal during device introduction, manipulation, and withdrawal.

The valve‘s unique geometry—featuring precision-engineered cross-hair or slit configurations—enables smooth device passage with minimal friction while instantly resealing upon instrument removal to prevent backflow, air embolism, and blood loss.

With excellent biocompatibility, and stability across extreme temperatures, our silicone hemostasis valve is an ideal sealing solution for medical device manufacturers, OEM partners, and healthcare product developers.

Application of Silicone Hemostasis Valve

The silicone hemostasis valve is widely used across interventional and minimally invasive medical applications:

Introducer Sheaths

Provide effective hemostatic sealing while allowing guidewires and catheters to pass smoothly during vascular access procedures.

Vascular Access Devices

Help minimize blood leakage and maintain a secure seal during diagnostic and interventional vascular procedures.

Y-Connectors & Hemostasis Valves

Serve as the primary sealing element in Y-connector hemostasis valves, maintaining a fluid-tight seal around interventional devices up to 7F–9F in diameter.

Neurovascular Devices

Ensure stable sealing performance during delicate neurovascular interventions.

Electrophysiology Devices

Support repeated device exchanges with consistent sealing performance.

Catheter Hubs & Fluid Management Systems

Prevent blood or fluid backflow when treatment catheters are placed in introducer sheaths.

Cardiopulmonary & Endovascular Procedures

Maintain hemostasis during the introduction, withdrawal, and use of diagnostic and interventional devices.

Disposable Medical Devices

Suitable for single-use medical products requiring precision sealing and medical-grade materials.

What Is a Silicone Hemostasis Valve?

A silicone hemostasis valve is a medical-grade silicone sealing component designed to provide reliable hemostasis, fluid control, and leak prevention in minimally invasive medical devices.

Manufactured from high-quality medical grade silicone material, this valve features excellent elasticity, biocompatibility, and long-term durability. Its self-sealing structure allows medical instruments, guidewires, or fluids to pass through smoothly while maintaining a secure seal to prevent blood leakage, fluid backflow, and external contamination.

During operation, the silicone hemostasis valve opens under applied pressure or instrument insertion, allowing controlled passage through the valve. After the pressure is released or the instrument is removed, the silicone material quickly returns to its original shape, creating a reliable seal and maintaining system integrity.

Compared with traditional sealing components, silicone hemostasis valves offer superior flexibility, consistent sealing performance, and excellent recovery after repeated use. They are widely used in catheter systems, introducer sheaths, vascular access devices, and other medical fluid control applications requiring high reliability and cleanliness.

Hopewell provides custom silicone hemostasis valve solutions with customized dimensions, slit designs, hardness, and performance characteristics to meet different medical device requirements.

Key Features of Silicone Hemostasis Valve?

1. Reliable Hemostasis & Blood Leakage Prevention

The precision-engineered silicone hemostasis valve forms a reliable seal around guidewires, catheters, and other interventional instruments, effectively minimizing blood leakage while maintaining smooth device insertion and withdrawal. The self-sealing design automatically closes upon instrument removal to prevent backflow and contamination.

2. Excellent Elasticity & Recovery

Medical-grade silicone provides outstanding elasticity and compression set resistance, allowing the valve to repeatedly open and reseal without losing its sealing performance. This ensures consistent operation throughout multiple device exchanges during a single procedure.

3. Superior Biocompatibility

Manufactured from medical-grade silicone materials, our hemostasis valves are suitable for medical device applications and comply with stringent industry requirements for safety and reliability. Materials meet ISO 10993 and USP Class VI biocompatibility standards.

4. Wide Operating Temperature Range

Silicone remains flexible and stable across a broad temperature range (typically -40°C to 150°C), ensuring reliable performance during manufacturing, sterilization (autoclave, EtO, gamma), transportation, and clinical use.

5. Smooth Device Passage with Minimal Friction

The precision slit design allows guidewires and catheters to pass through with minimal resistance, reducing the force required for device manipulation and improving procedural efficiency.

6. Customizable Design for Specific Applications

Hopewell provides fully customized silicone hemostasis valve solutions, including:

Valve type

Outer diameter and overall dimensions

Slit shape, size, and configuration

Material hardness

Color (transparent, translucent, or custom colors)

Device compatibility (catheter size, guidewire diameter)

7. Precision Manufacturing with Tight Tolerances

Using advanced liquid silicone rubber (LSR) molding technology, custom silicone hemostasis valves can be manufactured with tight dimensional tolerances and excellent consistency, meeting the strict quality requirements of medical device manufacturers.

8. Sterilization Compatibility

Silicone hemostasis valves are easily sterilizable via multiple methods, including autoclaving, ethylene oxide (EtO), and gamma radiation, without compromising material integrity or sealing performance.
