WATCHMAN Access Systems Recalled by Boston Scientific for Air Embolism Risk

Sign in to monitor this recall

Summary

Boston Scientific Corporation has recalled 340,185 units of its WATCHMAN TruSeal, FXD Curve, and TruSteer Access Systems because patients may be at an increased risk of air bubbles entering the bloodstream (air embolism) during heart procedures. This issue is most likely to occur when the procedure is performed without specific breathing support (positive pressure-controlled ventilation), particularly under conscious or deep sedation. The recall covers several models used to facilitate the insertion of WATCHMAN Left Atrial Appendage Closure devices. Healthcare providers should stop using these devices and contact the manufacturer or their distributor for instructions on returns or corrections.

Risk

Air embolism occurs when air enters the heart and is pumped through the body, which can cause a stroke, heart attack, or even death. Patients are at approximately three times higher risk of this complication when these systems are used without pressure-controlled breathing support, especially if they have low heart pressure or airway obstructions.

What You Should Do

  1. This recall involves several models of the WATCHMAN Access System, including the TruSeal (SGL, DBL, ANT), FXD Curve (Sgl, Dbl), and TruSteer versions, which are used in heart procedures to reach the left atrium.
  2. Identify if your product is affected by checking the Material Number (UPN) and GTIN on the product label. Affected UPNs include M635TS70010, M635TS70020, M635TS70040, M635TS80010, M635TS80020, M635TU70010, M635TU70020, M635TU70040, M635TU80010, M635TU80020, and M635TU90050. See the Affected Products section below for the full list of affected codes.
  3. Stop using the recalled device. Contact the manufacturer or your distributor to arrange return, replacement, or correction.
  4. Call the FDA at 1-888-463-6332 or visit www.fda.gov/medical-devices/medical-device-recalls for more information regarding this recall.
