AtriClip LAA Exclusion System

97% successful left atrial appendage (LAA) exclusion1-11 resulting in the electrical isolation of the LAA12-17

  • No Device Migrations
  • No Device Related Complications
  • With more than 5 Years Follow-up

Within minutes of the epicardial application of the AtriClip Device, the LAA becomes electrically isolated from the left atrium and ischemic injury results in the cessation of electrical activity in the LAA.12-13 Postoperatively, the excluded and necrosed LAA is resorbed and no longer a factor in the propagation of electrical activity.14-16

Hallmarks of AtriClip Device Excellence

Epicardial Exclusion

  • Implant is not in the blood stream
  • Ischemic injury electrically isolates the LAA
  • Atrophy and resorption of the LAA

Constant Closing Force

  • Exclusion is maintained throughout ischemic changes to the tissue by continuous closing force.

Parallel / Linear Closing

  • Minimized occurrence of tissue folds with optimal apposition of tissue along long axis of LAA ostia

Tissue Compression / Atraumatic

  • No cutting or piercing minimizes procedure and device complications.

AtriClip Implant
