Abstract
A catheter includes an elongate body having first and second chambers extending within the elongate body from a proximal end to an intermediate section, the first chamber having a first opening and the second chamber having a second opening at the intermediate section. The catheter also includes a valve structure that may have first and second barrier elements to open or close the first and second openings, respectively. The first and the second barrier elements may be coupled by a connecting structure moving within an opening in a guide structure. Alternatively, the first and the second barrier elements may be coupled in a U-shaped structure that moves over the guide structure. To permit flushing of the chambers when the first and second openings are closed, the first and second chambers may also be connected by a connecting channel defined by an opening in a wall of the elongate body.
