Patent ID: 7691079

Claim:
A device for tamponade of body cavities and for mechanical anchoring of a catheter having a shaft with an end, the device comprising: a flexible tube segment having an inner wall and an outer wall that surround an interior space wherein said tube segment is inflatable to assume a torus geometry with said inner wall defining an internal area, and the internal area is configured without through-passing support bodies so that a displacement of tube wall material between said inner wall and said outer wall of said tube segment is possible as inflation proceeds, wherein said tube segment is preformed in such a way that a tube portion that forms the inner wall of said tube segment after invagination is smaller in cross section and has a greater wall thickness than a tube portion forming the outer wall, and wherein said tube segment further comprises: a. two ends, which are fastened to a same closing element, configured so that a torus geometry is striven for as said inflatable tube segment is inflated and b. said closing element is a pipe nipple and said two ends of said tube segment are joined together fluid-tightly.
