Abstract
Tissue imaging and extraction systems 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 extraction system can include features or instruments for procedures 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.
