The WATCHMAN™ Difference

WATCHMAN is a one-time procedure that reduces the risk of stroke in people with atrial fibrillation.  WATCHMAN is as effective at reducing the risk of stroke as warfarin.

But unlike warfarin, the WATCHMAN Implant also reduces the long-term risk of bleeding. Newer blood thinners offer an option to warfarin, but they don't take away the long-term risk of bleeding. 

The WATCHMAN Procedure

WATCHMAN is implanted like a stent, by means of a narrow tube inserted through a small cut in your upper leg. Your doctor will then guide WATCHMAN into your heart.

The procedure is done under general anesthesia and takes about an hour. Patients commonly stay in the hospital overnight and leave the next day.




The WATCHMAN Implant has a proven record of safety—with over 20,000 procedures performed worldwide and over 10 years of clinical studies in more than 2,000 patients. It is the only device of its kind approved by the U.S. Food and Drug Administration. 

Is WATCHMAN™ an Option for Me? 

WATCHMAN is for people who:
  • Have atrial fibrillation not caused by heart valve problems
  • Have been recommended to take blood thinning medicines by their doctor
  • Can take warfarin but need an alternative to blood thinners because they have a history of bleeding or a lifestyle that puts them at risk for bleeding
People who should NOT be considered for the WATCHMAN™  Implant, but are not limited to: 
  • Patients who cannot take warfarin, aspirin, or clopidogrel 
  • Patients who should not or cannot undergo heart catheteization prodcedures 
  • Patients who have an allergy or sensitivity to nitinol (nickel and titanium) or any of the other materials in the WATCHMAN Implant
  • Patients with a left atrial appendage that is too large or too small to fit the WATCHMAN Implant
