Abstract
In an embodiment, a brachytherapy device includes a cartridge adapted for use with a brachytherapy applicator. A plurality of therapeutic members are stacked parallel to one another within the cartridge. Each therapeutic member includes a radioactive seed that is at least partially encapsulated by a polymeric material. Additionally, each therapeutic member can include at least one protrusion on an outer surface of the encapsulating polymeric material to reduce a tendency for the therapeutic member to migrate and rotate within a patient's body after the therapeutic member is implanted.
