Abstract: PROBLEM TO BE SOLVED: To arrange a movable sheath in a target position in a lumen or a cavity, by arranging in a removable manner a means that allows the operation of an occluding device stored in the movable sheath and its cavity from the proximal end, in order to deflect it transversely at the distal position. SOLUTION: The catheter lead-in system is furnished with a lead-in catheter 12 and a occluding device 14, the lead-in catheter 12 has a movable sheath 16 and a hemostatic valve assembly 18, and the occluding device 14 is provided with a movable body 20 and an operating handle 22. And withdrawal of the occluding device 14 in an appropriate position of the lead-in catheter 12 having a tapered distal head 26 extending from the distal position 28 of the sheath 16 proximally relevant to a thumb lever 30 causes a transverse deflection of the distal portion of the movable sheath 16 arranged on the occluding device 14. And preferably, at least the movable sheath 16 has a heightened movability across an area where it is deflected transversely.

Abstract: PROBLEM TO BE SOLVED: To provide a delivery catheter which enables easily releasing of a tubular prosthesis by keeping the axial position of a prosthesis releasable at a distal end on a slender flexible shaft while the prosthesis is covered with a sheath. SOLUTION: A delivery catheter 30 is constituted of a sheath 32, a shaft or a catheter body 34 inside. The sheath 32 has a central lumen 36 extending to a proximal handle 40 from a distal end 38. The shaft 34 is slidably housed in a lumen 36 and has a distal end 42 and a proximal handle 44. A tubular prosthesis P radially compressible is housed into a circular space between the external surface of the shaft 34 and the internal surface of the lumen 36 passing through the sheath 32. A direct pressure from the sheath 32 works to maintain the radial compression of the prosthesis P.
