Abstract

One embodiment is a medical device with a flexibly deformable external hose. The external hose includes multiple openings, at least one of them arranged in a first end of the external hose. It includes a flexible internal hose, which is arranged on the inside of the external hose. The internal hose, in an expanded state, has an external diameter that is at least equal to the internal diameter of the external hose, closing the openings of the external hose. The external diameter of the internal hose can be transitioned from the expanded state into a radially contracted state, exposing the openings. A connection firmly connects the external hose and the internal hose on the first end of the external hose, and closes them in fluid-tight manner. A connector supplies the fluid into the intervening space between the external and the internal hose.
