Title
(EN) THERAPEUTIC INFUSION NEEDLE
(FR) AIGUILLE DE PERFUSION D'AGENT THÉRAPEUTIQUE
Abstract
(EN)
Devices and methods useful for injecting therapeutics into the body of a patient are illustrated and described herein. In certain aspects, needle assemblies comprising a needle having a needle shaft with one or more side openings and a needle sheath slidably moveable along the needle shaft to selectively expose or cover all or a portion of the one or more side openings are provided. Such assemblies may include an interference fit between the needle sheath and the needle shaft and/or a seal positioned around the needle shaft proximal of the plurality of one or more side openings and configured to prevent fluid from leaking between the needle sheath and the needle shaft and beyond a proximal end of the needle sheath.

La présente invention concerne des dispositifs et des procédés utiles pour injecter des agents thérapeutiques dans le corps d'un patient. Selon certains aspects, des ensembles aiguille comprenant une aiguille ayant une tige d'aiguille comportant une ou plusieurs ouvertures latérales et une gaine d'aiguille pouvant se déplacer de façon coulissante le long de la tige d'aiguille pour exposer ou recouvrir de manière sélective la totalité ou une partie de la ou des ouvertures latérales sont prévus. De tels ensembles peuvent comprendre un ajustement serré entre la gaine d'aiguille et la tige d'aiguille et/ou un joint d'étanchéité positionné autour de la tige d'aiguille à proximité de la pluralité d'une ou plusieurs ouvertures latérales et configuré pour empêcher la fuite d'un liquide entre la gaine d'aiguille et la tige d'aiguille et au-delà d'une extrémité proximale de la gaine d'aiguille.
