SmartPill > Home
The U.S. Food and Drug Administration (FDA) has approved for sale the
SmartPill, an ingestible sensor system from SmartPill Corporation of
Buffalo, NY. The size of a vitamin pill, the sensor collects data
from a patient's gastrointestinal (GI) system and reports it back to
the capsule's SmartPill GI Monitoring System.
The patient swallows the single-use capsule in a doctor's office, and
the sensor measures pressure and pH, gastric emptying time, combined
small and large bowel transit time, and total transit time. The pill
travels through the GI tract, transmitting data to the receiver, which
is slightly larger than a cell phone, and is worn on the patient's
belt. Data is then downloaded from the receiver to the monitoring
system for the doctor to analyze.
