Abstract: A clip device for gripping biological tissue of a patient includes a clip having a first arm and second arm closeable by operation of a wire that is reciprocally moveable in a longitudinal channel of a sheath; and a bendable member at a distal end region of the sheath. The bendable member can be an integral portion of the sheath or a separate structure. The bendable member is configured to allow a distal end of a clip to rotate or swing toward a proximal end region of the sheath of the device, which orients the clip relative to the sheath to facilitate grasping of tissue even when the approach of the clip is tangential to the tissue, e.g., at an angle (?) less than 90. The bendable member can be configured to allow a distal end of a clip to rotate or swing toward a proximal end region of a sheath and form an angle of up to at least about 45 degrees, such up to about 60 degrees or up to about 90 degrees, or higher.

Abstract: A method for manufacturing a high-pressure tank including a liner that stores gas and a reinforcing layer made of a fiber-reinforced resin and covering an outer surface of the liner includes: a first step of forming a cylinder member made of the fiber-reinforced resin; a second step of forming two dome members made of the fiber-reinforced resin; and a third step of forming a reinforcing body that is the reinforcing layer by joining both end portions of the cylinder member and end portions of the two dome members, respectively. The first step includes forming the cylinder member by winding a release material around a mandrel and winding the fiber-reinforced resin on the release material.

Abstract: A tank production method for preventing generation of non-uniform stacked portions in a sheet layer while securing the strength of the tank, the method including a winding step of winding resin-impregnated fiber sheets to form a sheet layer with a predetermined thickness. The winding step includes divided winding steps of winding divided fiber sheets obtained by dividing a fiber sheet into a plurality of divided fiber sheets having a length shorter than the length required to form the sheet layer with the predetermined thickness.
