摘要： PURPOSE: To provide an improved method and a device to help removal of a stent implanted in a body by a method not to cause injury. CONSTITUTION: An endoscope 60 is introduced to the base end position of an implanted stent 10, and a cannula is introduced through the endoscope 60. Then, a wire guide is led through the lumen of the stent and introduced to a duct. Then the cannula is removed, and a stent exchanging cable is advanced to the base end position of the stent 10. The stent exchanging cable is rotational torque-transmittable, and once the exchanging cable is placed in a fixed position, a rotary dial is rotated to engage the cable with the threaded part in the lumen of the stent. Then the stent 10 and the cable are removed together through the endoscope 60, the endoscope 60 and a wire guide are left as they are to use them for implantation of the exchanging stent.

摘要： PURPOSE: To tear off a catheter without exerting influence on arrangement of a guide wire in a tube by introducing the guide wire into the tube. CONSTITUTION: An endoscope having a through passage is inserted into the body until a tip opening approaches a Vater's nipple. A tearing-off catheter 10 is inserted into the endoscope up to coming out of the opening of the endoscope. A guide wire is also inserted through the catheter. Afterwards, the catheter 10 can be cloven in the lengthwise direction along two long grooves arranged in a main body of the catheter by pulling tabs 23 and 24 arranged on the base end. In this way, the catheter 10 can be torn off and removed without affecting the arrangement of the guide wire.

摘要： PURPOSE: To perform incision of a human body organization as a wire guide is left in the human body, and prevent electric shock to the human body by current short-circuitting. CONSTITUTION: A wire guide 1 comprises an insulation outer tube 20 comprising extruded Teflon material, an inner shaft 30 comprising Nitinol (R) material, and a platinum alloy coil 40 at an end. The outer tube 20 has such inner sizes that the inner shaft 30 is loosely contained with an air cushion to provide additive insulation effect, and the platinum alloy coil 40 is also loosely positioned inside the outer tube 20. The Nitinol (R) material forming the inner shaft 30 has a high electric resistance, and it also has super-elasticity characteristics to improve controllability of the guide 1. A taper is provided at an end part of the inner shaft 30, and this end part is installed on the platinum alloy coil 40. The coil is radiation-impermeable, thereby recognition of a tip by X-ray observation is facilitated.

摘要： PROBLEM TO BE SOLVED: To provide an activating mechanism for an endoscopic ligator, mounted on an endoscopes of every form and accurately controlled to perform ligature.
SOLUTION: This activating mechanism for activating the endoscopic ligator 14 includes: a mounting element; and an activating element connected to the mounting element, wherein the mounting element has such dimensions that it is directly inserted in an opening part of the base end of an operating channel 16a of an endoscope 10a and fitted in the working passage to mount the activating mechanism on the endoscope and includes a passage for receiving an activating braid of the ligator, which is introduced into an activating element of the activating mechanism through the working passage and a passage of the mounting element. The activating braid 15 provides a driving pin and a roller clutch mounted on a spool of the activating element to set the activating element in an engagement position or disengagement position and a knob for rotating the driving pin. When the driving pin engages with the roller clutch, the knob can be rotated only in one direction, and when it is in the disengagement position, the knob can be rotated in both directions.

摘要： PURPOSE: To make cutting off of the end of a catheter unnecessary, by making protrusion of a needle from the end of the catheter adjustable through a handle and a stopper member connected to the catheter head. CONSTITUTION: A handle 21 is provided with a Luer-Lok connector 22 and a metal tube fixed to a plastic tube. The plastic tube is movable between a first position where a needle 12 protrudes the end 26 of a catheter 10 and a second position where the needle retreats in the catheter 10. The movement of the needle is adjusted by moving the handle 21 against a catheter head 17. A stopper member 30 is adjustably mounted on the head 17 within the moving range of the handle 21. The position of the stopper member 30 is adjusted by turning the screw against the head 17. The adjustment of the position of the stopper member 30 controls the degree of protrusion of the needle 12.

摘要： PURPOSE: To obtain the medical cutting tool of sphincter for cutting a patient's sphincter along a cutting surface under the control of resisting to the externally bending of the cutting surface by making the second moment of inertia in the cross section larger than the first one. CONSTITUTION: A lead wire 43 is arranged in the first vertical inner cavity 55, and an intensified wire material 45 is preferably made of a spring steel, and is arranged in the second vertical inner cavity 57, preferably along the whole length of the inner cavity 57. The inner cavity 57 and the intensified wire material are preferably formed rectangular, and the width (W) is larger than the height (H). When a controlling handle 29 is operated, a blade tip 53 is moved within the cut surface and the patient's sphincter is cut. This movement is caused by stretching the lead wire 43 of pulling a cutter 33 from an opening, and by pulling a remote position 47 to a near direction and by making the blade tip 53 to sweep out the cut surface. The bending is carried out around a bending axis (B), in contrast the bending receives a resistance around a resistant axis (R). Since the width (W) is larger than the height (H), the moment of inertia in the cross section (IR) is larger than the same (IB). Accordingly, there is a larger bending resistance around an axis (R) than around an axis (B).

摘要： Medical devices (20), systems and related methods for delivering a tissue anchor (26). One embodiment of such a medical device generally comprises a needle (22) and a sheath (24) that assist in retaining the tissue anchor, connected to a suture (40) at the distal end (42) of the needle during manipulation of the medical device. The needle has a needle lumen (32) sized to slidably receive the tissue anchor. The sheath has a sheath lumen (44) sized to slidably receive the needle. A distal end of the sheath defines a sheath slot (48) sized to receive the suture (40) therein. The medical systems include one or more tissue anchors in conjunction with one of the medical devices.
