WATCHMAN FLX™ Pro Device

The WATCHMAN FLX™ Pro Device is designed with three first-ever features. The enhanced device features HEMOCOAT™ Technology to improve the healing process, radiopaque markers for precise device placement, and a new 40 mm size for larger appendages.

Coated for Controlled Healing

HEMOCOAT™ Technology is a durable, thromboresistant coating that results in less inflammation and leads to faster, more complete endothelialization.¹

Next Level Visibility

Three new radiopaque markers help position and anchor the device with a new level of visual accuracy.

Close with Confidence

A new 40 mm size to treat larger appendages and widest range of anatomies.
