MULTI-NEEDLE INJECTION DEVICE

摘要

A medical device and a method of treating stress urinary incontinence are provided. The device includes a cannula with a plurality of apertures. A plurality of needles is disposed within a lumen of the cannula. A handle includes a housing and a shifter mechanism to translate the plurality of needles from a first position in which the needles are disposed within the lumen of the cannula, to a second position in which a distal portion of each needle extends out of the lumen through respective apertures. The handle also includes a slot including a transversal track defining a potential range of rotational motion of the shifter mechanism with respect to the housing, and a plurality of longitudinal tracks defining a potential range of translational motion of the shifter mechanism with respect to the housing. The shifter mechanism may also rotate the cannula with respect to the handle.
