Venock Furthers Development of Automated Closure Device for Large Bore Venous Access Sites

July 21, 2021—Venock Inc. is developing a vascular closure system designed to close very large perforations that can be as big as the diameter of the operable vein or artery. The device is intended for large bore punctures (up to 30 F and larger) in vessels after transvenous catheter-based therapies such as atrial ablations, leadless pacemaker implantations, extracorporeal membrane oxygenation, and various structural heart therapies such as mitral and tricuspid valve repair and replacement.

In the company’s announcement, Professor Horst Sievert, MD, of Cardiovascular Center, Frankfurt in Frankfurt, Germany, commented, “The Venock device is designed to attain large bore venous closure in under a minute, thus saving time and money, while significantly reducing patient discomfort and time to discharge when compared to the recovery time from manual compression.”

The Venock system is not approved for sale or investigational use, advised the company. Venock Inc. is a privately held medical device company headquartered in New York, New York, with a subsidiary, Venock Medical GmbH, in Munich, Germany.

The company advised that animal studies have been completed that demonstrate the safety and efficacy of its large bore closure system. The Venock device was successfully used in multiple acute porcine studies to percutaneously close large bore access sites in the jugular vein. These access sites, whose diameter were as large as the vein itself, were immediately closed in a blood-tight manner without disrupting the venous blood flow or causing a stenosis.
