A template-assembly for effecting radiation treatment within an animal body by implanting one or more hollow needles at a desired location within the animal body includes a template frame being mountable to a stepping device of a radiation treatment device. The template frame has a needle guiding component having a plurality of guiding apertures for guiding the one or more hollow implant needles towards the desired location within the animal body. The template-assembly has a needle fixation component for fixating one or more of the implanted needles relative to the animal body, wherein the needle fixation component can be sutured to the skin of the animal body.

Template-assembly for effecting radiation treatment in an animal body

The invention relates to a method and apparatus for temporarily inserting and positioning at least one energy emitting source in an animal body, wherein the apparatus comprises at least: a hollow open needle having a proximal needle end and a distal needle end to be inserted into the body, so as to provide a channel in the body; a guide tube having a proximal guide tube end and a distal guide tube end to be inserted into the hollow open needle; the hollow open needle being retractable from the body over the guide tube; a first fixing element for fixating the guide tube with said proximal guide tube end relative to the body; a catheter tube having a closed distal catheter tube end and an open proximal catheter tube end to be inserted with its distal catheter tube end until a predetermined depth into the guide tube and the body via said proximal guide tube end and fixating the catheter tube to the guide tube; at least one energy emitting source for insertion into the catheter tube via said proximal catheter tube end and, which at least one energy emitting source is removed after a predetermined period of time from the catheter tube. According to the invention the hollow open needle and said guide tube are inserted through a part of said body leaving both proximal and distal ends of said guide tube exposed outside either sides of said part of said body, and a second fixing element for fixing the guide tube with said distal guide tube end relative to the body.

Method and apparatus for temporarily inserting and positioning at least one energy emitting source in an animal body

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.
