Apparatus and method for temporarily inserting a radioactive source in an animal body
First Claim
1. Method for temporarily inserting at least one radioactive source in an animal body comprising inserting a hollow open needle into the body so as to provide a channel in the body, inserting a flexible closed end sheath in the hollow open needle, retracting the hollow open needle over the flexible closed end sheath and out of the body while maintaining the flexible closed end sheath in position in the channel in the body, fixing the flexible closed end sheath relative to the body, inserting into the sheath and the body a radiation device having at least one radioactive source therein, detachably connecting the radiation device to a fixing element and after a predetermined period of time disconnecting the radiation device from the fixing element and removing the radiation device from the flexible closed end sheath and the body.

Abstract
A method and apparatus for temporarily inserting a radioactive source in a body. A flexible, closed-end sheath is first inserted in the body in a known way. Thereafter a radiation device having a radioactive source therein is inserted into the sheath and detachably connected to a fixing element. After a predetermined period of time, the radiation device is disconnected from the fixing element and removed from the body.
