Abstract
An endoscopy capsule having an image collecting capacity includes a deformable member configured to inflate when exposed to body liquid. The deformable member includes an effervescent material. When the effervescent reacts with water the resulting Carbon-Dioxide gas reduces the specific gravity of the endoscopy capsule. The capsule is contained within a shell or dome when swallowed. The shell or dome is configured dissolve in either a low or high pH environment.
