Abstract
A medical device is configured to position a bag member filled with a therapeutic substance in a prescribed region of the brain. The use of this medical device involves, with a sheath inserted in the brain region, filling a therapeutic substance into a bag member through an infusion tube, followed by retracting the sheath relative to the infusion tube until the bag member protrudes forward beyond the distal end of the sheath. After this, the bag member is put indwelling in the brain region by moving an operating member relative to the infusion tube to detach the bag member from the distal end of the infusion tube.
