Abstract
A catheter assembly includes: a catheter including a main lumen and one or more sub lumens provided separately from the main lumen; and an inner needle extending through the main lumen; and a deflection suppression mechanism configured to suppress deflection of the inner needle. The one or more sub lumens respectively communicate with one or more sub openings formed in the catheter. The catheter is configured to advance with respect to the inner needle. The deflection suppression mechanism comprises a contact support portion that contacts the catheter when the catheter advances with respect to the inner needle. The contact support portion is configured to contact the catheter at (i) a location proximal of a distal-most one of the one or more sub openings, and/or (ii) a location proximal of a step portion generated in the catheter as the one or more sub lumens are formed.
