DEVICES, SYSTEMS, AND RELATED METHODS FOR DELIVERY OF FLUID TO TISSUE

摘要

Abstract Needleless injection device and method, with ejection orifices and distal end control features. Used as a fluid delivery system with injector source. An access device comprises minimally invasive, tubular delivery lumens like catheters and endoscopes, and apposing jets selectively fired to force injection orifice of tube-like device against target tissue. Firing mode includes continuous firing during injection. Fluid stream passes through tissue surface and disperses as fluid particles in tissue below tissue surface.
