Current Trans-Venous Procedures

Current therapies that require large bore venous vascular access:


  • ASD Closure
  • Left Arterial Appendix Occluder
  • Mitral Valve Repair (currently only one technology available)
  • Vena Cava Filter
  • Atrial Ablation
  • Pulmonary Embolectomy
  • Venous Thrombectomy

These trans-venous therapies add up to approximately 5 million procedures per year in USA and Europe.

Upcoming Trans-Venous Procedures

A dramatic increase in interventional procedures that require large bore venous vascular access site is expected once novel technologies under development for structural heart treatment in development will mature.

  • Transcatheter Mitral Valve Repair
  • Transcatheter Mital Valve Prosthesis Implantation
  • Transcatheter Tricuspid Valve Repair
  • Transcatheter Tricuspid Valve Prosthesis Implantation
  • Intra-Atrial Shunt Therapy
  • Left Ventricle Restoration
  • Left Ventricle Volume Reduction
  • Right Ventricle Assist Devices

As soon as these procedures are fully developed and utilized, the market for large bore venous access closure is expected to grow to 30 million procedures per year in the USA and Europe.

As of today there exists no effective vascular closure device for large bore punctures of venous vessels in the clinical practice.


The Venock System

The Venock vascular closure device is a percutaneous hand held device for automated closure of a large bore puncture in the femoral vein following an interventional procedure. The device is inserted over the already positioned guidewire in the vein and the perforation is tightly sealed within 1-2 minutes procedure time.

Advantages of Venock Vascular Closure Device

Closure within 1-2 minutes

The current practice is to stop venous bleeding with half an hour manual pressure, followed by compression bandage and 6 hours immobilization.

Quick sealing of the vein puncture will allows for earlier patient mobilization.

Earlier discharge

The current practice is to keep patients overnight in the hospital, being immobilized and bedridden with a compression bandage and sand sack.

Quick sealing of the vein puncture will allow for earlier patient discharge.

Less complications

Sealing of the vein puncture by compression results in hematoma, pain and swelling. Patient immobilization increases the risk for vein thrombosis.

Reliable and quick sealing of vein puncture will reduce serious complications.

Cost savings

Quick sealing of the vein puncture will free up resources and more interventional procedures can be converted from inpatient to outpatient settings.

Consequently, the utilization of Venock Closure device is cost effective.
