摘要： A brachytherapy treatment device includes at least one tubular insertion member, an expandable member, and means for deflecting the at least one tubular insertion member. The tubular insertion member has a longitudinal axis and proximal and distal ends. The expandable member is disposed on and surrounding the distal end of the tubular insertion member. The distal end of the at least one deflected tubular insertion member within the first expandable member is offset from the longitudinal axis when deflected. The at least one deflected tubular insertion member is configured to receive a radiation source to position a radiation source offset with regard to the longitudinal axis to form an asymmetric radiation dosing profile. Additional brachytherapy treatment devices and methods for forming an asymmetric radiation dosing profile are disclosed.
