PillCam SB is a tool for visualization of the entire small bowel and for detecting small bowel abnormalities. It is the only capsule endoscope indicated for use in patients two years of age and older. The PillCam SB video capsule measures 11 mm x 26 mm and weighs less than 4 grams. The video capsule contains an imaging device and light source and transmits images at a rate of two images per second, generating more than 50,000 pictures during the eight-hour procedure. PillCam SB was initially cleared by the u.S. Food and Drug Administration in 2001. Now in its second-generation, PillCam SB 2 captures the broadest mucosal area per image with the widest field-of-view. In addition, advanced optics and Automatic Light Control improve image quality and illumination.
