A dilation system containing a physical factor F and F forces arising from the internal pressure having braided metal wire meshes (41) with different angles (4) and (17) placed longitudinally in between two layers of thermoplastic Hookian material (161) and (121) which meshes are able to adsorb the mechanical work from internal pressure and prevent any longitudinal displacement during inflation by contra posing forces working in different directions and able to recover the original dimension with pressure release c h a r a c t e r i z e d in that the received mechanical work of the meshes (41) due to internal pressure will modify the original pitch from (5) to (11) and from (6) to (15) and are able to prevent longitudinal displacement (Po) during expansion of the distal section by movement in opposite direction and recover the same original dimension after pressure release. |
