A medical device includes a catheter having an opening formed in a side portion of the catheter, an infusion tubing extending within the catheter along an axial direction of the catheter an infusion needle disposed at a distal portion of the infusion tubing, a connecting part which bendably connects the infusion needle to the distal portion of the infusion tubing, and a bending unit by which the infusion needle located inside the catheter so as to face the opening is bent at the connecting part at essentially a right angle with respect to the distal portion of the infusion tubing.
