Abstract: A treatment device includes a flexible sheath; a control wire that can move axially within the flexible sheath; a first treatment member connected to a distal end of the control wire; a second treatment member connected to a distal end of the first treatment member; and a protection member that covers the second treatment member depending on the mode of operation. When the treatment device is in a first treatment mode, the second treatment member projects from a distal end of the protection member. When the treatment device is in a second treatment mode, the first treatment member projects from the distal end of the flexible sheath, and the protection member covers the second treatment member.

Abstract: A treatment tool for an endoscope of the present invention includes a sheath, a balloon provided at the sheath and configured to be expandable to an inflated state from a reduced diameter state by injecting a fluid, a shaft member inserted through an inside of the balloon and configured to extend along a longitudinal axis of the sheath from a distal end of the balloon to a proximal end thereof, and an adhering portion provided on a side of an inner surface of a central portion of the balloon in a direction of the longitudinal axis, formed of an adhering material applied or adhered to the shaft member and configured to hold the central portion in a state in which the central portion is reduced in diameter.

Abstract: An apparatus for insertion into a body through a working channel of an endoscope includes a catheter including a dilator, a guide tube disposed in a lumen of the catheter, and a handle including a puncturing actuator operatively coupled to the proximal end of the guide tube. The dilator may be a cautery device and/or a balloon. The apparatus may also include a stylet needle that includes a cutting distal end for puncturing tissue and extends through a lumen in the guide tube. The handle may further include a stopper detachably coupled to the puncturing actuator to fix a position of the puncturing actuator on the handle, and moveable on the handle independently of the puncturing actuator when detached from the puncturing actuator. The disclosed embodiments also include a method for forming a passageway in a wall of a hollow body organ using the apparatus.

Abstract: A tissue clipping device and system, and method for clipping tissue are disclosed. The tissue clipping device includes a clip with clip arms that is slidably disposed within a channel of a lock tube. The clip is designed to move between an open configuration in which distal ends of the clip arms are separated from each other for receiving tissue therebetween, and a closed configuration in which the distal ends of the clip arms are closer to each other than in the open configuration for clipping the tissue received therebetween. The tissue clipping system further includes a delivery device for delivering and deploying the tissue clipping device. The delivery device is releasably coupled to the tissue clipping device.

Abstract: A treatment tool for an endoscope includes: a sheath; a balloon provided at a distal end of the sheath, and configured to be expandable from a folded initial shape to an unfolded inflated shape; an inner shaft configured to protrude from a distal end of the balloon through an inside of the balloon; a middle marker; and at least one or more positioning markers provided on the inner shaft independently of the middle marker. The balloon has a proximal end-side region, a distal end-side region, and a middle part. At least one of the positioning markers is positioned on the inner shaft at same a longitudinal position as the proximal end-side region.

Abstract: A treatment instrument for an endoscope is equipped with a sheath; and a balloon which is provided at the sheath, the balloon being configured to be expandable to an unfolded inflated shape from a folded initial shape by supplying a fluid, the balloon having a first region and a second region provided at both end portions in a longitudinal direction, and an intermediate section provided between the first region and the second region. In the initial shape of the balloon, an amount of residual strain of the intermediate section is larger than the amount of residual strain of the first region and the amount of residual strain of the second region. When an internal pressure of the balloon has a first internal pressure value, the first region and the second region are unfolded to be faster than the intermediate section, thereby having a greater diameter than the intermediate section.
