Models G228, G237, G247, and G248
- 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, 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™ MR-Conditional systems allow patients to receive full body MR-Conditional scans at 1.5T or 3T without exclusion zone, scan duration, or patient height restrictions**
- 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.
