ABSTRACT:
A lead for implantation in the epidural space has an inflatable balloon which is sealed against a first side of the lead so it inflates away from the first side. The balloon contacts walls of the epidural space and urges an electrode on the first side against the dura. A syringe for inflating the balloon has a spring to absorb travel of a plunger actuator when fluid pressure in the balloon exceeds tension of the spring.
