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 (40), 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 (34) 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.

L'invention concerne des dispositifs qui conviennent pour injecter un fluide à un tissu sans utiliser d'aiguille, et des procédés associés. Ces dispositifs comprennent un élément ou une combinaison d'éléments tels que des orifices d'éjection, les éléments de commande d'extrémité distale, ou des combinaisons de ces éléments. Les systèmes peuvent comprendre un système d'apport de fluide possédant une source d'injecteur et un dispositif d'accès. Le dispositif d'accès peut comprendre une lumière d'apport tubulaire invasive au minimum telle qu'un cathéter ou un endoscope. Le dispositif de type tube comprends aussi un ou plusieurs jets d'apposition qui sont sélectivement allumés pour appliquer en force l'orifice d'injection du dispositif de type tube contre le tissu cible. L'allumage sélectif peut comprendre un allumage continu pendant l'injection pour améliorer l'efficacité du traitement
