1. A needleless fluid delivery system, comprising:
- an endoscope having a flexible body between a proximal end and a distal end, the flexible body defining a work lumen and an optical viewing feature;
a needle injector device having a pressurized fluid source and an injector tube, the injector tube defining a non-circular cross-section and including at least one injection orifice proximate an injection end; and
an adapter ring removably fixed at the distal end of the flexible body, the adapter ring including a non-circular injector ring corresponding to the non-circular cross-section of the injector tube such that the non-circular injector ring slidably receives the injector tube so as to fix the position of the injection orifice relative to the endoscope.

Abstract
An endoscope adapter ring for a needleless fluid delivery system for delivering therapeutic fluids to treatment sites within a patient. The needless fluid delivery system can include an automated injector source and a needleless access device. The access device can include a delivery scope and a treatment specific applicator. The adapter ring is operably attached to the endoscope to keep the injector lumen in a known orientation for the use of a side injector.
