A fluid dispensing device for attachment, in use, to a balloon catheter. The device comprises a housing (2) defining a chamber (3) for retaining, in use, balloon inflation fluid. An outlet (4) attaches, in use, to a catheter inflation lumen, and dispensing means dispenses fluid, in use, from the chamber via the outlet into the catheter lumen. An indicator indicates when a predetermined volume of fluid has been dispensed from the outlet. The indicator may take the form of a graduated window 12 and an internal marker such as a ball 9. Alternatively, it can be an internal sensor attached to an external display screen. In preferred embodiments, the outlet has a tamper evident seal and the dispensing means may be a plunger removably attached to an external key to prevent inadvertent dispensing of the fluid. |
