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.
