Abstract
A catheter assembly includes: a catheter including a circumferential wall and a distal opening; an inner needle inserted through the catheter, the inner needle having a sharp needle tip at a distal end of the inner needle; and a deflection suppression mechanism that supports the inner needle via the catheter to suppress deflection of the inner needle, the deflection suppression mechanism including a contact support portion that is configured to support the catheter when the catheter is advanced with respect to the inner needle. The circumferential wall of the catheter includes one or more side holes configured to allow passage of a liquid between an inside and an outside of the catheter. In an initial state before the catheter is advanced with respect to the inner needle, the contact support portion is located proximal of a distal-most one of the one or more side holes.
