| 摘要 |
The present invention relates to a balloon catheter comprising at least one inflatable balloon and a fluid inlet for injecting fluid into the balloon or a device adapted to be connected to a balloon catheter with at least one inflatable balloon and a fluid inlet for injecting fluid into the balloon which device has at least one channel for fluid which channel, when connected to a balloon catheter, is in communication with the inlet or an outlet from the balloon catheter. The balloon catheter or the device comprises a relief or by-pass valve means placed in or in connection with a channel for fluid, which relief or by-pass valve means normally is closed, but open when the balloon pressure reaches a predetermined level, so that further injected fluid can escape through the relief or by-pass valve. |
