Abstract
A method for implanting seeds in or about a target area, such as a tumor, within a patient. The implantation device includes an implantation needle having a bore extending longitudinally therethrough from a proximal end to a distal end of the needle, the needle bore being adapted to permit at least one seed to pass therethrough. An elongated plunger extends longitudinally through the implantation device in aligned relation to the needle bore. An optical device is carried by and operatively connected to the plunger to provide visual assistance to an operator of the implantation device to guide and verify implantation of the ejected seed into the target area.
