Abstract

A capsule type medical device system comprising a means (4) for detecting the position of a capsule type medical device (2) introduced into an organism, an electrode (5) disposed in proximity to the outer surface of the capsule type medical device (2) and imparting an electric stimulus to the tissue of the organism, and a means (6) for controlling a current fed to the electrode (5) wherein the control means (6) controls the current fed to the electrode (5) according to positional information detected by the position detecting means (4).

Description

technical field [0001] The present invention relates to a capsule-type medical device system for observing a living body, in particular, capable of imparting electrical stimulation to living tissue, moving it in the body, and observing a desired site. [0002] This application claims priority over Japanese Patent Application No. 2003-432674 filed on December 26, 2003, Japanese Patent Application No. 2003-381202 filed on November 11, 2003, and Japanese Patent Application No. 2003-431118 filed on December 25, 2003 Right to use its content here. Background technique [0003] Conventionally, various inspection methods such as physical examination and endoscopic examination are generally known as methods for checking the health status of the subject. In addition, there is known an inspection method using a capsule medical device in which a test object formed in a capsule shape is swallowed and injected into the body, so that health status inspection can be easily performed.
