What are the release criteria for the Watchman FLX PASS device?

The release criteria for the Watchman FLX PASS device focus on essential factors such as position, anchor, size, and seal. These parameters are critical to ensure that the device is adequately deployed and functions effectively to occlude the left atrial appendage.

Position ensures that the device is placed correctly within the appendage, maximizing its efficacy in preventing thrombus formation. The anchor is crucial because a secure hold provides stability and prevents device migration post-deployment. Size pertains to the appropriateness of the device in relation to the left atrial appendage to ensure a proper fit, as an oversized or undersized device could lead to complications or failure to occlude effectively. Lastly, the seal must be tight to prevent blood from flowing back into the appendage, which is vital for the obstruction's success and minimizing the risk of stroke.

While the other options mention important aspects related to device deployment or considerations in practice, they do not encompass the specific criteria required for the decision to release the Watchman FLX PASS device after implantation.
