Multi-lumen medical balloon structure comprising a cylindrical region, defined by a cylindrical wall portion, divided into balloon lumens by planar wall portions, said wall portions each consisting essentially of an orientable thermoplastic polymer, at least a portion of which has been at least partially oriented by blow molding to form very thin-walled, flexible, high strength balloon lumens, said balloon structure comprising three or more such balloon lumens with substantially parallel longitudinal axes wherein each of said balloon lumens shares a common, integrally-formed at least partially oriented wall portion with at least one adjacent balloon lumen along at least a section of their respective axial lengths and further wherein at least one of said planar wall portions defines a chord across a cross section of the cylindrical region.
