Serenity Medical technology is focused on stenting the transverse-sigmoid sinus to relieve the various clinical symptoms of venous sinus stenosis. Our first clinical trial is on relieving clinical symptoms in patients with idiopathic intracranial hypertension (IIH).

The River Stent is an investigational device and not commercially available

Our River Stent is designed specifically for stenotic sinuses and offers a number key advantages.


The ability to conform to the transverse-sigmoid sinus via a highly flexible material.


Serenity’s River Stent is soft, important for both ease of placement and to conform to the sinus anatomy.

Reduced metal surface area

The Serenity reduced metal surface area aims to minimize the risk of venous thrombosis.

Variable radial force & diameter

The Serenity stent offers variable radial force and variable diameter, to adapt to the anatomy and physiology of the sigmoid and transverse sinuses.

One is greater than two

Today, sinus stenting is performed with arterial stents—often with two stents partially covering each over. Two stents increase the risk of cortical vein thrombosis.
