VIVA™ XTCRT-D - 1

Product specifications Physical characteristics Volume3 35 cm3 Surface area of device can 57 cm2 Radiopaque IDc PXT Materials in contact with Titanium, polyurethane, human tissued silicone rubber Hybrid CFx lithium/silver vanadium oxide a Volume with connector ports unplugged. b Grommets may protrude slightly beyond the can surface. c The radiopaque ID, which includes a Medtronic-identifier symbol, can be viewed in a fluoroscopic image of the device. d 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. Replacement indicators Recommended < 2.73 V on 3 consecutive daily Replacement Time (RRT) automatic measurements End of Service (EOS) 3 months after RRT Maximum energy levels and typical full energy charge times Maximum programmed energy 35 J Maximum delivered energy^ 36 J Typical charge time at Beginning of Service (BOS)d Typical charge time at Recommended 0 Replacement Time (RRT)d . s a Energy delivered at connector block into a 50 Q load. b For 35 J programmed energy, delivered energy exceeds 35 J. c Energy stored at charge end on capacitor. d Charge time during a nonwireless telemetry session may be slightly higher.
