<p>A device is provided for plugging a hole in a membrane. The device comprises a cap including a chamber for storing compressed gas, an inflatable bladder connected to the cap and a first conduit via which fluid can escape from a distal side of the membrane whilst the device is inserted into the hole. The device further comprises a first control means for controlling the escaping fluid through the device, a second conduit via which a compressed gas can flow from the chamber into the inflatable bladder and a second control means for controlling the flow of compressed gas from the chamber into the bladder. The bladder is arranged to be inserted at least partially through the hole in the membrane in a non-inflated state and at least partially inflated after it has been inserted therein.</p> |
