1. A leak sensing unit for determining a presence of a leak within a gastric band placed around a patient'"'"'s stomach for the treatment of obesity, the leak sensing unit comprising:

  • a pressure sensor for sensing a pressure level within the gastric band;

    a processor coupled to the pressure sensor for determining whether the sensed pressure level indicates a leak in the gastric band;

    a timing unit coupled to the processor, the timing unit for determining timing information used by the processor in determining whether the sensed pressure level indicates a leak in the gastric band;

    a memory coupled to the processor for storing the sensed pressure levels; and

    a digital display coupled to the processor for displaying information related to the sensed pressure level,wherein the pressure sensor, the processor, the timer, the memory, and the digital display are retained as a unit.
