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. In an initial state before the catheter is advanced with respect to the inner needle, a distal-most one of the one or more side holes is in a distal portion of the catheter, and the contact support portion is proximal of a proximal-most one of the one or more side holes.
