A device, and related method, for introducing fiber material into a body includes a tubular member with a lumen extending to an opening in a distal end portion of the tubular member and a mechanism in the tubular member for passing the fiber material through the lumen and the opening and into the body. The mechanism can be a helical member rotatable within the tubular member to convey the fiber material through at least a portion of the lumen, out of the opening, and into the body, and the fiber material can be particles in a carrier that are injected into the lumen by a syringe coupled to the tubular member. The mechanism alternatively can be a sleeve slidable within the tubular member to force the fiber material through at least a portion of the lumen, out of the opening, and into the body, and the fiber material can be a suture or thread that is fed into a distal portion of the tubular member where it collects until it is forced out of the opening by the sleeve. The mechanism also can be a push rod slidable within the tubular member to push the fiber material through at least a portion of the lumen, out of the opening, and into the body, and the fiber material can be one or more pellets.
