Abstract

A medicine injection catheter includes: a catheter main body formed with a medicine supply lumen; a tubular body connected to the distal end of the catheter main body and having a lumen communicating with the medicine supply lumen; an injection needle connected to the tubular body; a tubular cover member that accommodates the tubular body and that is configured to be advanced and retracted in the axial direction of the catheter main body between a first position where a distal end of the injection needle is accommodated in the tubular cover and a second position where the distal end of the injection needle protrudes forward from the inside space; a closing member to close and open the lumen of the tubular body, a motion conversion mechanism which converts advancing/retracting motion of the cover member into movement of the closing member to close the lumen of the tubular body.
