An anchored dilator includes a push tube having proximal and distal push tube portions. A dilator tip is coupled with the distal push tube portion and is configured for selectable coupling with a catheter. The dilator tip includes an anchor cuff having a cuff interface. The anchor cuff is configured to transition between a shuttle configuration having a shuttle profile and an anchored configuration having an anchored profile larger than the shuttle profile. A cuff operator assembly is configured to transition the anchor cuff between the anchored and shuttle configurations. The cuff operator assembly includes a cuff operator movably coupled with the dilator tip, and an operator shaft coupled with the cuff operator. The operator shaft extends toward the proximal push tube portion. Actuation of the cuff operator with the operator shaft transitions the anchor cuff between the shuttle configuration and the anchored configuration.
