1. A medical device comprising: an element with a reservoir that limits the space inside the element with the reservoir, wherein the element with the reservoir is intended to be inserted into the patient’s body； a port that connects the space inside the element with the reservoir to an area outside the element with the reservoir； a tubular element that forms a lumen and has a distal end and a proximal end, the distal end of the tubular element is connected to the inner surface of the element with the reservoir in the space inside so that a portion of the inner surface of the element with the reservoir provides a seal at the distal end of the lumen, and the tubular element extends through the port , and the proximal end of the tubular element is configured to remain outside relative to the space inside the element with the reservoir； the tubular element is designed to receive the delivery of filling material into the lumen, which causes the passage of an additional portion of the length of the tubular element through the port and into the space inside the element with the reservoir, and the tubular element is configured to accommodate the filling material in the lumen of the tubular element. 2. The device according to claim 1, in which the element with the reservoir is selected from the group consisting of a balloon element, a structure with a twisted frame, polyurethane foam, silicone foam, foam with shape memory, swelling substances and hydrogels. 3. The device according to claim 1, wherein the element with the reservoir is a balloon element. The device according to claim 3, in which the balloon element consists of a material selected from the group consisting of PTFE, ePTFE, silicone and elastomeric1.
