Abstract
The present invention relates to a stent delivery device having: a first support rod into which a first movable body is inserted; a fixed magnet; and a second support rod into which a second movable body is inserted, wherein a first driving magnet included in the first movable body and a second driving magnet included in the second movable body rotate relative to each other by means of the control of an external magnetic field at a predetermined angle around an axis in a first direction with respect to the fixed magnet, thereby separating a first coupling piece and a second coupling piece from a first coupling groove and a second coupling groove and enabling a stent to unfold.
Claims9
A stent delivery apparatus comprising:
- an inner body in which a first support rod and a fixed magnet are coupled in a first direction;
- and
- a first movable body having inner space into which one end of the first support rod is inserted, and including a first driving magnet arranged at one end of the first movable body, which is adjacent to the fixed magnet;
- wherein a stent is coupled to surround the first movable body and the fixed magnet, and
- wherein by control of an external magnetic field, the first driving magnet rotate about the first direction with respect to the fixed magnet such that the same polarities thereof as the polarities of the fixed magnet are arranged in a row in a first direction.
