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.

Abstract: A scanner unit includes: a tubular elastic part provided with marks outside a prescribed bonding region set on an outer surface thereof and; and a piezoelectric element that is bonded to the bonding region. The piezoelectric element includes: a piezoelectric body having two mutually opposing electrode faces; and marks that are different from each other, respectively provided on the two electrode faces. The mark provided on one electrode face has a shape that matches the mark provided outside the bonding region when the piezoelectric body is bonded to the bonding region so that the other electrode face contacts the outer surface.

Abstract: A medical device is provided. The medical device includes a puncture needle that is inserted into body tissue from outside a body and pierces membranous tissue near pulsating tissue inside the body tissue; a tubular protection member that is disposed on the outer side of the puncture needle; a pulse-information acquisition portion that acquires pulse information of the pulsating tissue; and a driving unit that moves the puncture needle and the protection member relative to each other in synchronization with the pulse information of the pulsating tissue acquired by the pulse-information acquisition portion, in such a manner that a tip of the puncture needle is retracted toward a proximal end from a distal end of the protection member when the pulsating tissue expands and that the tip of the puncture needle is projected farther forward from the distal end of the protection member when the pulsating tissue contracts.
