Features

Improved reach and enhanced range 

  • Adjustable curve designed to reach a large variety of patient anatomies† and accommodate challenging anatomical situations, including a large right atrium‡
  • Achieves various curve shapes during implant using only this steerable guide catheter 
  • Handle mechanism secures a desired shape, reducing the need to physically hold the curve in place during the procedure

Stable and supportive

  • Rigid proximal portion provides mechanical support and stability for lead delivery and fixation; while the softer distal end minimizes tissue injury
  • Catheter deflection is designed to push tip toward the targeted tissue and maintain stability on the septum 
  • Catheter provides a stable workspace to pass guidewires and leads in the cardiac venous anatomy 
  • Dual-braided lumen provides stability§

Increased implant success 

  • C304-HIS catheter design allows the tip to achieve an angle closer to perpendicular in the region of the His-bundle for a higher fixation rate versus the C315-HIS catheter†,‡
  • C304-HIS catheter may be used in conjunction with the Medtronic Model 3830 pacing lead 
  • Catheter body is radiopaque for visibility on fluoroscopy and has improved visualization of the catheter (versus C304-L69) with an additional marker at the distal end

Maneuverability 

  • Handle mechanism enables tip deflection by transmitting fine movements to the catheter shaft, allowing placement at the bundle of His 
  • Designed for improved manipulation◊ — deflect for gross movement and torque for minor movement 
  • Braided, kink-resistant catheter design with multiple transition zones allows for various stiffness characteristics, providing flexibility to navigate curvatures of venous anatomy

† Using modeling study of 20 different patient anatomies, selected to include patients with atria ranging from 38–197 mL RA volumes. 

‡ Across tested anatomies, the C304-HIS improved fixation success rate in larger RAs with volumes between 110 mL and 139 mL (versus C315).

§ Within the wall thickness of the device lumen is a second braided lumen for the pull wire.
