摘要： A brachytherapy instrument and method is disclosed for delivering therapeutic substances such as radioactive seeds, to internal organs, such as the prostate. The instrument includes a needle (602) and stylet (604) which are capable of reciprocating relative to one another, but which can be selectively fixed against such movement. The needle (602) is loaded with radioactive seeds, and the stylet (604) advances the seeds to the distal end of the needle.
