Abstract

Various rotatable shafts and linkage mechanisms configured to allow imaging and access to tissue within a body are provided. In an exemplary embodiment, an introducer system has a rotatable sheath and a linkage that can rotatably engage each other. The rotatable sheath has a distal portion extending at a non-zero angle relative to a proximal portion thereof. The linkage has an exit lumen on its distal end and a plurality of entry lumens on its proximal end. The linkage merges the plurality of entry lumens into the exit lumen, and the exit lumen is aligned with the rotatable sheath upon engagement. Fluid and/or surgical instruments can thus be passed from the plurality of entry lumens of the linkage, through the exit lumen of the linkage, and into the rotatable sheath. The linkage and the rotatable sheath can both receive an imaging device therethrough.
