ABSTRACT:
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.
