Brachytherapy capsule and combination of a brachytherapy capsule with a guide wire

摘要

A capsule for taking up at least one radioactive source for application in brachytherapy and to be connected to a guidewire, the capsule having a cylindrical mantle that can be closed on the proximal end by means of a coupling element, and the capsule having a rounded top section at its distal end, the mantle and the inner surface of the top section defining a substantially straight circular-cylindrical cavity, in which the operation at least one radioactive source is placed, the inner surface of the top section, at least in a peripheral area thereof, being curved in distal direction and the cavity continuing somewhat in the top section, and the end of that least one radioactive source, which is located near the inner surface of the top section, is finished in a complementary curved fashion.
