Detailed description
Description The Medtronic Enterra II Model 37800 Neurostimulator is a programmable device designed to deliver therapy through gastric electrical stimulation when connected to a lead system. These components comprise the implantable portion of the Medtronic Enterra II system. The operation of the neurostimulator is supported by a clinician programmer. The neurostimulator (Figure 1) operates on a sealed battery and electronic circuitry to provide controlled electrical pulse stimulation, through the implanted lead system. A wide range of noninvasively programmable parameters and stimulation modes are available. The neurostimulator provides current parameter information, via telemetry, when used with the clinician programmer. System Components * Neurostimulator: Medtronic Enterra II Model 37800 * Controlling Devices: Medtronic Model 8840 Clinician Programmer with Model 8870 Application Card. Model 8527 Printer optional. * Lead: Medtronic Enterra Model 4351 Unipolar Lead

Instructions for use Implanting physicians should have experience in the surgical and/or implantation techniques for the Enterra II system, operational and functional characteristics of the Enterra II system, 12 English 37800 2014-03 and experience in the continued management of patients by stimulation parameter adjustment. Physicians may contact Medtronic before prescribing or implanting an Enterra II system for the first time, and request a referral to a physician experienced in the use of the Enterra II system. Implanting physicians should be thoroughly familiar with all product labeling. Cautions: * When using sharp instruments near the neurostimulator, be extremely careful to avoid nicking or damaging the case, the insulation, or the connector block. Damaging the neurostimulator may require surgical replacement. * Do not use saline or other ionic fluids at connections, which could result in a short circuit
