CATHETER DEVICE

摘要

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.

主权项

1. A catheter, comprising:
an elongate body having a proximal end and a distal end; a first chamber extending within the elongate body from the proximal end to a first chamber opening at the distal end; a second chamber extending within the elongate body from the proximal end to a second chamber opening at the distal end; a valve structure at the distal end of the elongate body that is configured to move relative to the elongate body between a closed position in which the first and second chamber openings are covered by the valve and an open position in which the first and second chamber openings are uncovered by the valve; and a channel located between the proximal and the distal ends of the elongate body that extends between the first chamber and the second chamber that provides fluid communication between the first and the second chambers when the valve structure is in the closed position.
