Serenity Medical technology is developing a portfolio of complementary technologies to optimize venous sinus stenosis procedures.
The River stent is the first FDA HDE-approved venous sinus stent for severe, refractory idiopathic intracranial hypertension (IIH), a condition that causes debilitating headaches, vision loss, and cognitive impairment, and has long lacked a purpose-built treatment option.
Approved under an FDA Humanitarian Device Exemption, it gives physicians a dedicated tool for patients who are resistant or intolerant to medical therapy.
Serenity’s River Stent is deliverable through a 6F system, and advances smoothly like a microcatheter – important for ease of placement and conformability to the venous sinus anatomy.
The ability to conform to the transverse-sigmoid sinus via a highly flexible material.
The Serenity reduced metal surface area aims to minimize the risk of venous thrombosis.
The Serenity stent offers variable radial force and variable diameter, to adapt to the anatomy and physiology of the sigmoid and transverse sinuses.
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.
