VISIA AF MRI™ VR SURESCAN™ Model DVFB1D1 Product specifications Physical characteristics Volumea Surface area of device can Materials in contact with human tissuec Titanium, polyurethane, silicone rubber Battery chemistry Hybrid CFx lithium/silver vanadium oxide Battery model Volume with connector ports unplugged. b The radiopaque ID and Medtronic radiopaque identifier 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. a Replacement indicators Recommended Replacement Time (RRT) < 2.73 V on 3 consecutive daily automatic measurements Maximum energy levels and typical full energy charge times Maximum programmed energy Maximum delivered energya,b 36 J Maximum stored energyc Typical charge time at Beginning of Service (BOS)d Typical charge time at Recommended Replacement Time (RRT)d a 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 § MR Conditional with PhysioCurve™ Design § SmartShock™ Technology § OptiVol™ 2.0 Fluid Status Monitoring § Complete Capture Management™ § AF Diagnost
