Tissue imaging system variations are described herein. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Additionally, the system can be deployed in a number of various ways such as clearing blood clots, emboli, and other debris which may be present in a body lumen. Other variations may also be used for facilitating trans-septal access across tissue regions as well as for balancing body fluids during a procedure.
