Abstract
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.
