Abstract
An indwelling device for embolization comprises a coil portion (11) having a proximal side and a distal side and having a lumen extending in a longitudinal direction, a stretch-resistant member (20) disposed in the lumen, wherein the indwelling device has a fixing structure in which the stretch-resistant member (20) is knotted to the detachable portion attached in the lumen of a proximal end part of the coil portion (11) and extending proximally from a proximal end of the lumen, in order for the stretch-resistant member (20) to be more securely anchored to the coil portion (11).
Claims18
An indwelling device for embolization comprising;
- a coil portion having a proximal end and a distal end and having a lumen extending in a longitudinal direction;
- a stretch-resistant member disposed in the lumen and extending from the proximal end part to the distal end part of the coil portion;
- a rod-shaped detachable portion having a rod part extending in the longitudinal direction, an end part of the rod-shaped detachable portion disposed in the lumen of the proximal end part of the coil portion so that another end part of the rod-shaped detachable portion proximally extends from the proximal end part of the coil portion, and
- a fixing structure including a knot in which the stretch-resistant member is knotted to the rod part of the detachable portion, the knot disposed on the rod part of the detachable portion.
A method for manufacturing an indwelling device for embolization comprising:
- disposing a stretch-resistant member inside a coil portion which extends in a longitudinal direction;
- inserting a detachable portion into a proximal end part of the coil portion, wherein the detachable portion has a rod part extending in the longitudinal direction;
- forming a fixing structure by knotting the stretch-resistant member to the rod part of the detachable portion to fix the stretch-resistant member to the detachable portion, whereby a knot is formed on the rod part of the detachable portion;
- applying an adhesive to the fixing structure;
- and
- curing the adhesive.
