Abstract

See full text

A loading clip for low dose radioisotope seeds has a body having a channel defined therein. The channel has a cavity adapted for receiving a radioisotope seed at a distal end. A slider member slidably positionable within the channel has a spring biased tooth at a distal end. A constant force spring member is slidably positioned within the channel between the slider member and the body. Radioisotope seeds are magazined into the loading clip biased against the constant force spring member by operation of the slider member extending the tooth over the cavity and retracting a radioisotope seed in the cavity into the channel. In one embodiment, radioisotope seeds are magazined into the loading clip that is then used to load an automated seed cartridge. In this embodiment, the loading clip has structure for mating with an aperture in the automated seed cartridge so as to introduce radioisotope seeds into the seed cartridge one at a time. Preferably, the loading clip is provided with a machine readable storage medium accessible via an electrical connector that stores indicia representing at least information about the radioisotope seeds located in the loading clip.
