摘要：
The invention features a system that includes an inner tube, an outer tube anda n actuator. The outer tube at least partially surrounds the inner tube sothat a medical device can be positioned between the inner and outer tubes. Theinner and outer tubes are configures to be capable of being disposed within abody lumen. The actuator is configured so that, as a force is applied to theactuator, the actuator can cause relative motion between the inner and outertubes. The mechanical advantage of the actuator can change as the actuatormoves.
