Encapsulated medical device and method of examining, curing, and treating internal region of body cavity using encapsulated medical device

摘要

An encapsulated medical device includes a radio antenna through which the encapsulated medical device transmits or receives a radio wave to or from an extracorporeal device. The encapsulated medical device is passed through the lumen of a body cavity in order to examine, cure, or treat an internal region of the body cavity under the control of the extracorporeal device. A capsule body included in the encapsulated medical device has an extended portion formed at an upper end of one axis of a cross section of the capsule body cut at right angle to the longitudinal axis thereof. The capsule body has a linkage hole bored in the extended portion thereof to allow a fluid such as a gas or humor to flow into forward and backward parts of the lumen through the hole.
