Abstract
A traceable device and procedure suitable for investigating gastrointestinal motility disorders by measuring transit time of the device as it is passed through the gastrointestinal tract of a patient. The device includes a core material configured to be imaged with a gamma imaging process and optionally also an x-ray imaging process, and a sealing material substantially insoluble in gastrointestinal fluids and fully encapsulating the core material.
Claims5
A traceable device comprising:
- a core material comprising a radioactive isotope visible with a gamma imaging process, wherein the core material is a single grain of rice and the radioactive isotope is thallium-201, gallium-67, and indium-111;
- and
- a sealing material substantially insoluble in gastrointestinal fluids and fully encapsulating the core material, wherein the sealing material comprises paraffin wax and prevents the core material from being dispersed in a human body after the device is administered orally to a patient and is present in a gastrointestinal tract of the patient.
