Patent ID: 8849366

Claim:
A catheter system comprising: a fibre-optic probe having a probe distal part; a flexible, elongated base body adapted to be applied to a vein central-venously and having a base distal end, the base body including a lumen that receives the fibre-optic probe; and an attachment element including a connector piece firmly connected to the fibre-optic probe and a counter-piece firmly connected to the base body, the connector piece being detachably connectable to the counter-piece so as to attach the fibre-optic probe with respect to the base body and provide removability of the fibre-optic probe from the base body by longitudinal displacement of the fibre-optic probe relative to the lumen when the connector piece and counter-piece are detached, the connector piece having a shaft piece that is adjustable in length so as to vary a length of the connector piece, wherein a distance between the distal end of the base body and the distal end of the fibre-optic probe is adjustable to a predetermined value in a connected state of the attachment element by the connection between the fibre-optic probe and the connector piece and the connection between the base body and the counter-piece.
