    Abstract: A catheter includes: a conduit part having a plurality of lumens whose external diameter at a tip side thereof is constant, each of the plurality of lumens extending along an axis line inside the conduit part; and a branched part that separates axis lines of the plurality of lumens from each other at a base end side of the conduit part. At an end of the conduit part inserted into inside the branched part, an opening of each of the plurality of lumens is provided along a different axis line with each other, and a level difference is formed at the end of the conduit part.

    Abstract: A pericardial-cavity observing method including: a step of inserting an endoscope sheath and an endoscope into a space between the heart and the pericardium; a step of disposing a protruding portion closer to the pericardium than an optical member is so that an angle that is formed between a centerline that passes through a center of the protruding portion and a center of the optical member and a tangent of the pericardium that passes through a foot of a perpendicular line drawn, from the center of the optical member of the endoscope, to the pericardium sagging down from the protruding portion toward the heart becomes greater than an angle formed between the centerline and an external common tangent of the protruding portion and the optical member; and a step of observing the heart by means of the endoscope.
