NCT00779363

Brief Summary

The objectives of this feasibility study are to evaluate the safety and functionality of the TANTALUS System with TANTALUS II IPG, to assess the effect of GCM signal application on trends of HbA1c, blood glucose and body weight changes.

Study Arms (1)

Implanted Device

EXPERIMENTAL
Device: rechargeable TANTALUS II

Interventions

Subjects will undergo an approximately two week baseline screening process. Eligible subjects will undergo device implantation. This will be followed by therapy initiation approximately one week after implantation. The device will then be activated to automatically deliver gastric contractility modulating (GCM) for 12 weeks of therapy. Stimulation will continue in for a safety monitoring period of 18 months following the therapy period.
