Abstract
A steering assembly of a medical device may comprise a handle having a recess and first and second wire guides disposed within the recess. At least one of the first or second wire guides may be keyed to the recess to prevent rotation of the first or second wire guide within the recess. First and second wire segments may be configured to steer a sheath coupled to the steering assembly in first and second directions. The first wire segment may pass through a first gap between the first wire guide and the second wire guide. The second wire segment may pass through a second gap between the first wire guide and the second wire guide. Neither of the first nor the second gap may occupy any overlapping space.
