Worley™ Advanced Lateral Vein Introducer

Request Information

To meet the challenges of cardiac resynchronization therapy (CRT), you need advanced LV leads and LV delivery systems that match the tortuosity of your patient’s anatomy. The Worley Lateral Vein Introducer (LVI) system is designed to offer you the flexibility you need for reliable and accurate placement of LV leads to their target location.

Features & Benefits

  • Soft radiopaque tip minimizes risk of vessel wall trauma and improves fluoroscopic visualization
  • Proximal and distal curves enhance sub-selective access to angulated lateral vein branches
  • 5F OD target vein selector for improved target vein selection and guide wire replacement
  • 5.5F or 7F ID LVI provides ample room to perform various advanced CRT implantation techniques
  • Multidurometer proximal curve construction delivers improved tip directivity
  • Braided sheath construction supports better torque control and stability. Sliceable sheath for easy removal
  • Side port allows open access infusion and contrast injection during implantation
  • Integrated break-away hemostatic hub and handle designed to protect against blood loss and air embolism. Hub requires no cutting. Secure hub grip reduces the risk of lead dislodgement during removal


When used together with the Worley Advanced CSG and Worley Vein Selector, the Worley Advanced LVI provides the tools and solutions needed to reduce implantation times, gain easier access to the target vessel, and improve chances for successful CRT implantation.1
