Patent ID: 6997862

Claim:
A prescription method to create a plurality of treatment strands, comprising: accepting a tissue treatment plan for the tissue to be treated, which treatment plan specifies a number and spacing of treatment seeds to be provided in each of a plurality of treatment strands that includes a distal end and a proximal end, where the distal end is intended to be implanted prior to the proximal end; and creating the plurality of treatment strands so that the treatment strands satisfy the treatment plan when distal ends of the treatment strands are implanted into a patient to the same depth using needles that are inserted into the patient to the same depth; wherein at least two of the plurality of treatment strands have a custom distal end spacing between the distal end of each treatment strand and the adjacent treatment seed to thereby enable the treatment plan to be satisfied when the distal ends of the plurality of the treatment strands are implanted to the same depth using needles that are inserted to the same depth; and wherein the custom distal end spacings of at least two of the plurality of the treatment strands have different lengths.
