Abstract
A method for delivery of a biocompatible polymer composition for treatment of urinary incontinence provides for delivery of biocompatible polymer material and a solidification agent through two lumens of a delivery device. The delivery device provides better control of the precipitation of the polymer in the periurethral tissue and detachment of the precipitated mass from the delivery device. The medical device includes a needle having a lumen and an inner cannula positioned within the needle lumen and movable longitudinally in the needle lumen from an extended position to a withdrawn position to sheer or cut the delivered mass of polymer material away from the needle tip.
