Non-Occlusive, Laterally-Constrained Injection Device

Abstract

A flexible cytoscope having an injection device with a cross-sectional profile allowing for irrigation flow without the risk of buckling or lateral deflection of the injection device. The cross-sectional profile is configured such that the injection device is constrained by the cytoscope lumen. The cross-sectional profile of the injection device can be formed integrally with the injection device or can alternatively comprise a secondary structure that is attached about an exterior portion of the injection device. The cross-sectional profile can be present at intervals along the length of the injection device or can extend the entire length of the injection device. The injection device can be configured such that the cross-sectional profile centers the injection device within the cytoscope lumen or in an off-set or non-centered position depending upon the treatment being performed.
