Abstract: A seed dispensing unit including an applicator handle holder configured to grasp a handle of an elongate applicator, wherein the elongate applicator includes a plurality of radiotherapy seeds at its distal end and a stylet handle grasper configured to grasp a handle of a stylet, wherein the stylet is within the elongate applicator. The seed dispensing unit further includes a casing allowing motion of the applicator handle holder relative to the stylet handle grasper, such that the stylet pushes a seed out of the distal end of the elongate applicator; and a slidable holder configured to couple with the applicator handle and slide relative to the casing.

Abstract: An applicator for delivery of radiotherapy seeds to a tumor of a patient through an elongate needle (104). The elongate needle comprises a needle handle (204) and a needle tube having a given length for insertion into the patient. The applicator comprises an elongate applicator tube (106) designed to pass through the elongate needle, wherein the elongate applicator tube defines an internal channel which receives one or more radiotherapy seeds (110), an applicator handle (210) configured to be attached to the needle handle (204); and a stylet (108) within the elongate applicator tube. The elongate applicator tube is longer than the elongate needle.
