Abstract
An anchor mechanism includes a sleeve to fit around a structure such as a radioactive source, a thermal ablation implant, a spacer, a strand or a radiopaque marker. The sleeve has a bore that extends an entire longitudinal length of the sleeve, and through which the structure fits, such that the structure can extend out from both longitudinal ends of the sleeve. One or more protrusion extends from an outer surface of the sleeve to engage surrounding patient tissue after implantation of the structure into a patient, to thereby reduce a tendency for the structure to migrate and rotate after implantation.
