One embodiment is a medical device for local application of a fluid, including a flexibly deformable external hose. The external hose includes multiple through-going openings, at least one of them is arranged in the area of a first end of the external hose. It includes a flexible internal hose, at least sections of which are 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, such that it closes 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, such that the openings are being exposed. A connection firmly connects the external hose and the internal hose to each other 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. |
