Patency System Overview
Overview
M2A Patency Capsule
The M2A Patency Capsule is an ingestible and dissolvable capsule comprised of a
body that surrounds a small inner Radio Frequency Identification (RFID) tag. It is
the same size of the M2A Capsule (26 mm long, 11 mm wide). The body is coated
with an impermeable membrane, except for a small window on the Timer Plug.
The Timer plug seals the capsule’s body. If the capsule is retained in the GI tract,
the Timer Plug erodes, allowing the penetration of body fluids into the capsule and
the dissolution of the body. The remaining fragments of the capsule can pass even
small orifices.
The tag retransmits an RF signal once it is excited by an appropriate RF signal from
the Patency Scanner. The latter detects the signal that indicates the presence of the
capsule in the GI tract.
