Patent ID: 7374547

Claim:
A device for identifying a location within a patient for delivery of a capsule, the device comprising: a probe that defines an inner lumen; a capsule detachably coupled to a distal end of the probe that includes a sensor; a pressure sensitive chamber within the inner lumen of the probe; a vacuum inlet at a proximal end of the probe that couples with a vacuum source; a vacuum outlet located at the distal end of the probe; a membrane that covers the vacuum outlet; and a pressure sensor to detect pressure variation within the pressure sensitive chamber indicative of proximity to a sphincter within the patient to identify a location for delivery of the capsule, wherein the vacuum inlet, when closed, forms the pressure sensitive chamber within the inner lumen of the probe, and the vacuum inlet, when opened, permits application of suction from the vacuum source within the inner lumen of the probe in order to remove or rupture the membrane that covers the vacuum outlet.
