1. A method for cutting a transverse carpal ligament in a hand of a patient, the method comprising:
advancing a distal end of a shaft of a device into the patient's hand below the transverse carpal ligament;
verifying a position of the distal end with an ultrasound device positioned outside the hand;
depressing a balloon activation lever on a handle of the device to activate a bellows in the handle to inflate at least one balloon coupled at or near the distal end of the shaft, wherein depressing the balloon activation lever causes a locking mechanism on the balloon activation lever to lock the balloon activation lever to the handle in a depressed position and thus lock the at least one balloon in an inflated state;
moving a blade of the device proximally along the shaft to cut the transverse carpal ligament;
positioning the blade at least partially within the shaft;
releasing the locking mechanism to release the balloon activation lever and thus allow the at least one balloon to deflate; and
removing the shaft from the hand.
