Described are devices useful to inject fluid to tissue without the use of a needle, and related methods; the devices include one or a combination of features such as ejection orifices, distal end control features, or combinations of these; the systems can include a fluid delivery system having an injector source and an access device; the access device can comprise a minimally invasive, tubular delivery lumen such as a catheter or endoscope; the tube- like device further includes one or more apposing jets that are selectively fired to force the injection orifice of the tube- like device against the target tissue; selective firing can include a continuous firing during the injection to improve the efficiency of the treatment.
Dispositifs et procédés connexes d'injection d'un fluide dans un tissu sans utilisation d'une aiguille. Les dispositifs présentent une ou plusieurs caractéristiques combinées tels qu'orifices d'éjection, commande d'extrémité distale, seules ou en association. Les systèmes peuvent inclure un système d'administration de liquide comportant une source d'injection et un dispositif d'accès. Ce dispositif d'accès peut comprendre une lumière d'administration tubulaire aussi peu effractive que possible telle qu'un cathéter ou un endoscope. Il peut également comprendre un ou plusieurs diffuseurs sollicités sélectivement pour forcer l'orifice d'injection dudit dispositif contre le tissu cible. La sollicitation sélective peut inclure une injection continue visant à améliorer l'efficacité du traitement.
