Reason for Recall

Boston Scientific has identified a higher likelihood of air embolism events when procedures are performed without positive pressure-controlled ventilation. According to published literature and clinical data, in percutaneous procedures requiring transseptal access to the left atrium when conscious or deep sedation is used, patients have an approximately three-times higher risk (U.S. study) of negative left atrium pressure and air ingress. This risk is especially prevalent in patients with pre-existing low left atrial pressure, hypovolemia, and partial upper airway collapse.

Product Description

WATCHMAN TruSeal Access System DBL, OUS, Material Number (UPN) M635TS70020; intended to provide vascular and transseptal access for all WATCHMAN Left Atrial Appendage Closure Devices with Delivery Systems.

Distribution Pattern

Worldwide.

Other Recalls by Boston Scientific Corporation

• Class I: Dangerous 12/19/2025
  Increased reports of stent deployment and expansion issues. The most common outcome reasonably foreseeable resulting from difficulty deploying the stent is prolongation of the procedure to exchange the device for a new one. The most serious reasonably foreseeable outcome in cases where the first flange is unable to deploy or expand would be a cascade of events resulting in additional intervention, either endoscopic or surgical, to remove the stent and close the puncture site.
