Study to evaluate the efficacy of gastric stimulation (GCM) using the DIAMOND System in the improvement of glycemic control measured by changes in HbA1c.

Relationship between blood TG level and the GCM efficacy will be evaluated.

• Type 2 diabetic subjects treated with oral anti-diabetic agents [Sulfonylurea, Metformin, thiazolinedione (TZD) or DPP-4 inhibitors]
• Stable anti-diabetic medications for at least 3 months prior to enrollment, six months for thiazolinedione (TZD)
• The subject has been under routine diabetes care of the investigator or another single physician that can supply a medical record for at least 6 months prior to enrollment
• HbA1c 7.3% and ≤ 9.5 % on Visit 1
• Stable HbA1c, defined as no significant change (variation ≤ 0.5%) between a historical value recorded in the subject's medical record within 3 months prior to enrollment and the HbA1c gathered on Visit 1.
• Fasting blood glucose >120 and < 350 mg/dl on Visit 1.
• Women with childbearing potential (i.e., not post-menopausal or surgically sterilized) must agree to use adequate birth control methods
• Stable weight, defined as no significant weight change (variation <3%) within three months prior to enrollment as documented in the subject's medical record. For the subject treated with thiazolinedione, stable weight within six months.

• Willingness to refrain from using prescription, over the counter or herbal weight loss products for the duration of the trial
• Alert, mentally competent, and able to understand and willing to comply with the requirements of the clinical trial, and personally motivated to abide by the requirements and restrictions of the clinical trial
• Able to provide voluntary informed consent

Exclusion Criteria:

• Insulin therapy in last 3 months

• Currently taking fibrates, nicotinamide and omega 3 fatty acids as antilipidemic treatment
• Subjects with an EF less than 35% or otherwise indicated for an ICD
• Taking medications known to affect gastric motility such as narcotics (chronic use) and anticholinergics/antispasmodics
• Experiencing severe and progressing diabetic complications (i.e. retinopathy not stabilized, nephropathy with macroalbuminuria)
• Prior wound healing problems due to staphylococcus or candida

• Cardiac history that physician feels should exclude the subject from the study.
• Use of another investigator device or agent in the 30 days prior to enrollment
• A history of life-threatening disease within 5 years of enrollment
• Change in diabetic medication from between Visit 1 and Visit 3.
