Abstract: Devices, assemblies, systems, and techniques described herein may facilitate the delivery of medical fluid, such as an adhesive, to a patient. For example, a medical assembly may include a flexible catheter configured to be disposed within an anatomical structure of a patient, wherein the flexible catheter defines a lumen configured to contain a volume of medical adhesive. The medical assembly may also include a shaft defining a shaft cross-sectional dimension smaller than a lumen cross-sectional dimension of the lumen, wherein advancement of the shaft through at least a portion of the lumen forces at least a portion of the volume of medical adhesive out of the distal opening of the lumen of the flexible catheter.
