Title:
BALLOON HAVING A MULTI-LAYER WALL STRUCTURE FOR THE TISSUE-CONSERVING LOW-PRESSURE SEALING OF OPENINGS AND CAVITIES IN THE BODY OF A PATIENT, IN PARTICULAR IN THE CASE OF CYCLICALLY FLUCTUATING FILLING PRESSURE VALUES
Document Type and Number:
WIPO Patent Application WO/2020/230111
Kind Code:
A3
Abstract:
The invention relates to a multi-layer balloon film material (1) in which one or more layers of an elastically deforming material (2) is/are combined with one or more layers of a plastically deforming non-elastic material (3), wherein the non-elastic layer counteracts the straightening properties of the elastic layer in the case of planar folds or bends in the balloon film material. In particular, the cross-sectional area of eyelet- or channel-shaped structures (6) which conducts secretions or fluids, which structures typically occur in the area of wrinkle-like invaginations of a residually sized balloon film in an organ lumen or a body cavity, can be reduced and, particularly in the case of cyclically changing filling pressures of the balloon, can be stabilized in such a way that an optimally sealing closure or tamponade effect is achieved across the largest possible filling pressure amplitudes.
