VIGILANT™ X4 CRT-D and
VIGILANT™ CRT-D

Cardiac Resynchronization Therapy Defibrillator

SmartCRT™ is Boston Scientific’s approach to personalise CRT therapy by providing physicians with smart solutions to optimise where, when, and how to pace. Heart Failure Sensor Suite provides multi-factorial, physiological, patient-specific data which can enable better informed decisions for treating HF patients. EnduraLife™ Battery Technology provides more power to use more of the device, featuring up to 13.3 years projected longevity with MultiSite Pacing turned on.* ImageReady™ MR Conditional Systems allow patients to safely undergo Full Body MRI scans up to 1.5T.**

VIGILANT™ X4 CRT-D and VIGILANT™ CRT-D

Models G224 and G247

 

  • VIGILANT X4 CRT-D offers SmartCRT™ technology, enabling physicians to offer a personalised care approach to all patients, including a wide range of options of where, when and how to pace
  • EnduraLife™ battery technology can offer up to 14.7 years battery life1 and 13.3 years with MultiSite Pacing switched on1.
  • 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 (0.86mm) tapered lead tip to improve predictability of accessing target vessels.
  • MultiSite Pacing allows 216 vector combinations to easily tailor device therapy, supported by automatic recommendations with the click of a button, for vectors and offsets in < 5 seconds.
  • This small (32.5 cm3) and thin (9.9 mm) high-energy device is designed to enhance patient comfort.2
  • The PaceSafe™ RV, RA, and LV auto threshold feature is designed to maintain adequate output safety margins.
  • Heart Failure Sensor Suite with a set of tools such as: Sleep Incline, AP Scan, LATITUDE™ NXT Remote Patient Management with weight scale and blood pressure sensors and Respiratory Rate Trend, to provide an advanced solution for patient comorbidities and HF monitoring.
  • ImageReady™ with Full-body MR scans safely in 1.5 Tesla environments**.
  • AcuShock™ Technology including Onset/Stability™, RhythmID™, Dynamic Noise Algorithm (DNA) for sensing, Automatic Gain Control (AGC) with programmable sensing floor, Narrow Band Pass Filter
  • 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.
