Program Impact

The WATCHMAN FLX Pro Device is built on the proven safety profile of the WATCHMAN FLX™ Device.1 With a 25% increase in device size range, the WATCHMAN FLX Pro unlocks up to 6% growth in the treatable patient population.*

New 40mm device
to treat the widest range of anatomies

A hemocompatible coating to promote faster, more complete healing2

Radiopaque Markers​
Three radiopaque markers help position and anchor the device to enhance placement for optimal sealing around the LAA​


Pre-clinical data

The fluoropolymer-coated WATCHMAN FLX Pro device showed significantly less thrombus and reduced inflammation in a challenging canine model. Mechanistic studies demonstrated that the WATCHMAN FLX Pro device binds more albumin, leading to reduced platelet activation, less inflammation, and greater endothelial coverage (EC).2​
