Tissue grasping device

A tissue grasping device comprising:

• a longitudinal axis member which is configured to be capable of inserting into a body;
• an actuating member provided at a distal end portion of the longitudinal axis member and configured to be capable of grasping a tissue;
• a wire member elongated to an outside of the actuating member and being curved in a loop shape;
• a through hole formed in a distal end surface of the actuating member and holding a first end side of the wire member such that the first end side of the wire member is capable of moving with respect to the actuating member;
• and
• a direction restriction portion provided at a side surface of the actuating member and fixing a second end portion of the wire member to the actuating member such that an elongated direction of a second end side of the wire member is coincide with a direction intersecting a side surface of the actuating member.
