More on WATCHMAN FLX Pro Device

The WATCHMAN FLX Pro device is based on the WATCHMAN FLXTM LAACdevice's demonstrated safety and operational performance. The most recent WATCHMAN FLX Pro device has been improved with a coating meant to decrease device-related thrombus and promote quicker, more regulated healing and endothelization of the device surface. Additionally, newly-added visualization indicators are meant to improve device placement for the best LAA sealing.

The WATCHMAN FLX Pro device will be assessed in the post-market HEAL-LAA research, which will start in the coming weeks and track the progress of about 1,000 patients with NVAF who had the device implanted at 60 sites in the United States.

Significance of the New Device

Per Boston Scientific’s management, the newest LAAC technology, intended to improve post-procedure healing, increase the accuracy of WATCHMAN FLX Pro implants, and broaden the size range of treated appendages, is now available to clinicians in the United States. The WATCHMAN FLX technology has been improved, speeding up implant procedures and letting doctors give their patients the best possible care.

The fully rounded design that enables medical professionals to enter and move around the left atrial appendage securely is one of the primary features of the WATCHMAN FLX Pro device that has been carried over from the original WATCHMAN FLX. The company believes that the WATCHMAN device's progress also holds out hope for a future with lower thrombosis risk, which could allow patients to have a more straightforward post-implant medication regimen.  

Industry Prospects

Per a report by Grand View Research, the global left atrial appendage closure devices market size was estimated at $986.35 million in 2021 and is expected to witness a CAGR of 20.5% by 2030.
