[Design and application of distal radial artery hemostat]

Area of Science:

• Cardiovascular Interventions
• Medical Device Design
• Vascular Access

Context:

• The transradial approach is standard for coronary angiography and percutaneous coronary intervention (PCI).
• Increasing use reveals complications like radial artery occlusion, nerve injury, and spasm.
• The distal radial artery approach offers benefits but lacks specialized hemostatic devices.

Purpose:

• To address the limitations of existing hemostatic methods for distal radial artery access.
• To design and invent a novel hemostatic device for distal radial artery puncture.
• To improve safety, efficacy, and patient comfort during interventional procedures.

Summary:

• A cardiovascular physician developed a distal radial artery hemostatic device, patented as ZL 2021 2 2097829.6.
• The device features a glove with a silicone gasket to apply targeted compression at the puncture site.
• It provides effective hemostasis with reduced pressure, minimizing complications and patient discomfort.

Impact:

• Facilitates wider adoption of the distal radial artery approach for interventional therapy.
• Reduces the incidence of radial artery occlusion and nerve injury.
• Enhances patient comfort and procedural outcomes in cardiovascular interventions.
