Abstract
The invention discloses a laser application set, which is an interventional application set for minimum invasive, laser-induced thermotherapy of soft-tissue tumors. In accordance with the invention the laser application set is designed in such a manner that an introductor tube (6) with a stylet (12) is provided and accommodates a tunneled catheter (17) with an internal stylet (20).
Claims18
A laser application set to treat tumors in which the distal end of a tunneled catheter (17) from synthetic materials, preferably PE, FEP, PTFE, is air- and fluid-tight sealed and movably guides an optical waveguide (33), characterized in that an introducer tube (6) with a closely fitting interior stylet (12) is provided and a tunneled catheter (17) is fitted with a closely fitting internal stylet (20), in which, upon removal of the stylet (12) from the introducer tube (6), the tunneled catheter (17) with the internal stylet (20) can be closely fitting inserted into the introducer tube (6) and projects from the distal end of the tunneled catheter (17) and in which the optical waveguide (33) can be inserted after the removal of the internal stylet (20) from the tunneled catheter (17).
A laser application set according to at least one of the aforementioned claims, characterized in that the proximal end of the introducer tube (6) is equipped with a T piece (9), with a silicone lamella (10) being placed between the T piece (9) and the introducer tube (6) and an external thread (13) fitted to the opposite side, with an interior membrane (16) and a hose lead (8) at the T piece (9) with a three-way faucet (7) fitted to its end.
A laser application set according to at least one of the aforementioned claims, characterized in that the stylet (12) is equipped with a grip end (14) with an internal thread which, in conjunction with the external thread (13) of the introducer tube (6), enables the locking of the stylet (12).
A laser application set according to at least one of the aforementioned claims, characterized in that the introducer tube (6) and the stylet (12) are hollow and from a material which is suitable for the MRT process, preferably PE, FEP, PTFE, etc.
A laser application set according to at least one of the aforementioned claims, characterized in that the stylet (12) in locked state projects by approx. 10 mm from the distal end of the introducer tube (6) and has an open stylet tip (15).
A laser application set according to at least one of the aforementioned claims, characterized in that the internal stylet (20) is made of a wire, which preferably is from a paramagnetic material, and is enclosed by a synthetic sheathing.
