摘要： The present invention provides a stent and tubular organ treatment device that can flexibly deform according to a curved portion of a tubular organ, contracts less in the longitudinal direction during insertion, and is easy to handle. A stent (1) is formed into a tubular form by arranging five tubular unit bodies in an axial direction and connecting them by a connecting filament (F). Each tubular unit is formed into a closed loop by cutting a metal wire to a predetermined length, bending it in a zigzag manner in a peripheral direction, and securely connecting both ends thereof. A tubular unit body (W) having two bent portions projected in the axial direction is connected to and rockably retained by a tubular unit body (U1). Similarly, a tubular unit body (V) is rockably retained by the tubular unit body (W), whereby the entire stent can easily deform into a curved shape. Shape-retaining members (X1) and (X2) composed of a shape memory alloy material are attached in the axial direction to the tubular unit bodies to maintain them in a curved state.

摘要： A stent placement device and a stent placement method, despite a simple structure thereof, can surely and readily deploy a stent by placing a distal end thereof prior to a proximal end thereof, having favorably low invasiveness, and smoothly insert and arrange the stent into a desired position, without damaging an internal lumen inner wall. A placement device 1 for deploying a stent 2 in an internal lumen includes a guide wire 3 which guides said stent 2 into a desired position in the internal lumen, a proximal tip 4 which is fixed at an intermediate position of said guide wire 3 and provided with a stent anchoring portion for anchoring said stent 2, and a stent converging and retaining member 5 which converges and retains a stent proximal end opening portion 2a of said stent 2.
