The amount of pressure in a surgical device, for example a catheter, with an inflation element, for example an inflation cuff, is indicated by a pilot balloon 9 formed from two sheets 10 arranged in face contact with each other and secured at the periphery in an air-tight manner as by a weld 12. At least one of the sheets 10 is deformable under the action of inflation pressure. <IMAGE> |
