Brief Summary Statement


WATCHMAN FXD Curve™ Access System – eIFU 51628404

CAUTION: Federal law (USA) restricts this device to sale by or on the order of a physician. Rx only. Prior to use, please see the complete “Instructions for Use” for more information on Indications, Contraindications, Warnings, Precautions, Adverse Events, and Operator’s Instructions.


The WATCHMAN FXD Curve Access System is intended to provide vascular and transseptal access for the family of WATCHMAN FLX LAAC Devices with Delivery System.


Do not use the WATCHMAN FXD Curve Access System if:

  • Intracardiac thrombus is present.
  • An atrial septal defect repair or closure device is present.
  • A patent foramen ovale repair or closure device is present.
  • Any of the customary contraindications for other percutaneous catheterization procedure (e.g., patient size too small to accommodate TEE probe or required catheters) or conditions (e.g., active infection, bleeding disorder) are present.
  • There are contraindications to the use of anticoagulation therapy, aspirin, or P2Y12 inhibitor.

For additional contraindications associated with the Closure Device, refer to LAAC Implant IFU.


Use of the WATCHMAN FXD Curve Access System for implantation of the family of WATCHMAN FLX LAAC Devices should only be performed by interventional cardiologists and/or electrophysiologists who are educated in percutaneous and transseptal procedures and who have completed the required WATCHMAN FLX family Physician Training program.

  • The WATCHMAN FXD Curve Access Sheath should not be used with any WATCHMAN Device that requires the use of a proximal marker band placed at, or just distal to LAA ostium prior to deployment.
  • Careful consideration should be given to use of the Access Sheath in pregnant and/or breastfeeding women due to the risk of significant exposure to X-rays and the use of anticoagulation medication.

For additional warnings associated with the Closure Device, refer to LAAC Implant IFU.


  • The LAA is a thin-walled structure. Use caution when accessing the LAA and deploying, recapturing, and repositioning the Closure Device.
  • Use caution when introducing any WATCHMAN FXD Curve Access System to prevent damage to cardiac structures.
  • Use caution when introducing Delivery System to prevent damage to cardiac structures. To prevent damage to the Delivery Catheter or Closure Device, do not allow the Closure Device to protrude beyond the Delivery Catheter when inserting the Delivery System into an Access Sheath.

For additional precautions associated with the Closure Device, refer to LAAC Implant IFU.
