Document Type and Number:
WIPO Patent Application WO/2019/026364
Kind Code:
A1
Abstract:
The present invention provides an in vivo indwelling instrument, an in vivo indwelling instrument delivery system, and an in vivo indwelling instrument manufacturing method wherein it is difficult for a tip and an elongation resistance member of a distal end section of a coil to stray from said coil. An in vivo indwelling instrument (10) having: a coil (11) that is formed by winding a wire member (12), and extends in a distal/proximal direction; a resin tip (20) that is connected to a distal end section of the coil (11); and an elongation resistance member (21) that is positioned in a lumen of the coil (11) and is connected to the resin tip (20), wherein the coil (11) has a contact section (13) that is the distal end section and in which neighboring wire members (12) are in contact for at least one turn, and a separated section (14) that is further to a proximal side than the contact section (13) and in which neighboring wire members (12) are separated, and a section of the resin tip (20) is present in the separated section (14).
