VIVA™ S CRT-D Model DTBB1D4 IS1/DF4 - 1

VIVA™ S CRT-D Model DTBB1D4 IS1/DF4 Physical characteristics Physical characteristics Volumea Surface area of device can Materials in contact with human tissuec Titanium, polyurethane, silicone rubber Hybrid CFx lithium/silver vanadium oxide Volume with connector ports unplugged. The radiopaque ID, which includes a Medtronic-identifier symbol, can be viewed in a fluoroscopic image of the device. c These materials have been successfully tested for the ability to avoid biological incompatibility. The device does not produce an injurious temperature in the surrounding tissue during normal operation. b ≤ 2.73 V on 3 consecutive daily automatic measurements Maximum energy levels and typical full energy charge times Maximum programmed energy Maximum delivered energy Maximum stored energy Typical charge time at Beginning of Service (BOS)d Typical charge time at Recommended Replacement Time (RRT)d Energy delivered at connector block into a 50 Ω load. For 35 J programmed energy, delivered energy exceeds 35 J. Energy stored at charge end on capacitor. d Charge time during a nonwireless telemetry session may be slightly higher. b c § CardioSync™ Optimization § SmartShock™ Technology § OptiVol™ 2.0 Fluid Status Monitoring § Complete Capture Management™ Replacement indicators Recommended Replacement Time (RRT)
