Exclusion Criteria:

• A tear of the supraspinatus tendon greater > 50% and any areas of full thickness tearing, concomitant tears > 25% of other rotator cuff tendons (infraspinatus, teres minor or subscapularis), or acute tear of the glenoid labrum.
• Evidence of systemic illness/infection requiring oral or IV antibiotics during the recruitment period.
• Evidence of overlying skin infection or lesion at the proposed device insertion point on the shoulder.
