Title
(EN) TISSUE MAPPING INJECTION DEVICE
(FR) DISPOSITIF D'INJECTION POUR LA CARTOGRAPHIE DE TISSUS
Abstract
(EN)
A tissue mapping injection device (10) suitable for use during a lymphatic breast mapping procedure is provided. The device includes a housing (12) having an elongated body portion (14) extending distally therefrom. A plunger (22) is slidably positioned within the housing (12). A connector rod (52) is secured to the forward end (46) of the plunger and extends distally through the elongated body portion. The plunger (22) and the connector rod (52) define a fluid delivery channel (38). A plurality of needles (54) are secured to the distal end of the connector rod (52). Each of the needles (54) is constructed from a shape memory material and defines a fluid injection channel (56) which communicates with the fluid delivery channel (38). The plunger (22) is movable from a retracted position wherein the needles (54) are positioned within the elongated body portion (14) to an advanced position wherein the needles (54) extend outwardly from the distal end of the elongated body portion (14).
(FR)
Dispositif (10) d'injection pour la cartographie de tissus, destiné à être utilisé pendant une procédure de cartographie du système lymphatique du sein. Ledit dispositif comporte un boîtier (12) doté d'un corps allongé (14) à extension distale par rapport au boîtier. Un piston (22) est placé coulissant dans le boîtier (12). Une tige de connexion (52) est fixée à l'extrémité avant (46) du piston et s'étend de manière distale dans le corps allongé. Le piston (22) et la tige de connexion (52) définissent un canal (38) d'apport de fluide. Une pluralité d'aiguilles (54) est fixée à l'extrémité distale du connecteur (52). Chacune des aiguilles (54) est constituée d'une matière à mémoire de forme et définit un canal d'injection de fluide (56) qui communique avec le canal d'apport de fluide (38). Le piston (22) est mobile entre une position rétractée dans laquelle les aiguilles (54) sont placées dans le corps allongé (14) et une position avancée dans laquelle les aiguilles (54) s'étendent vers l'extérieur depuis l'extrémité distale du corps allongé (14).
