摘要：
Torque devices for navigating a guidewire through a body lumen are disclosed. The devices have a variable speed transmission design, including at least a first transmission region along a first position of the device, and a second transmission region along a second position of the device. The first and second transmission regions have different diameters, thereby allowing rotational control of the guidewire between at least two different stroke angles.
