Product Details

INOGEN™ X4 CRT-D and INOGEN™ CRT-D

Models G140, G141, G146, and G148

  • The X4 CRT-D and ACUITY™ X4 lead portfolio features electrodes on a 3D spiral designed to allow pacing from a basal location without sacrificing fixation or thresholds; 17 pacing vector options to manage around PNS and high thresholds; and multiple lead shapes with a 2.6F (0.86 mm) tapered lead tip to improve predictability of accessing target vessels.
  • Projected to last 8+ years under true usage conditions.
  • This small (32.0 cm3) and thin (9.9 mm) high-energy device is designed to enhance patient comfort.
  • Offers an advanced system solution for patient comorbidities and HF monitoring (HF Perspectiv™ report, LATITUDE™ NXT Remote Patient Management with weight scale and blood pressure sensors).
  • Offers AcuShock™ Technology, multiple programmable options to reduce inappropriate and unnecessary shocks, including a choice of rhythm discriminators, antitachycardia pacing (ATP) therapy in all rates zones, and advanced sensing and filtering.
  • EasyView™ header and color coded lead ports designed to make the implant experience more efficient.
  • SafetyCore™ technology is intended to provide lifesaving shock therapy and basic pacing functionality in the event of an unrecoverable fault.
