Abstract:
A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).

Claim (Index 37):
The cannula system of  claim 1  wherein:\n the camera assembly comprises an imaging sensor and a prism, and the prism is the portion of the camera assembly overhanging and partially obstructing the lumen; wherein \n the imaging sensor has an imaging plane, and the prism is aligned with the imaging plane to direct light directed parallel to the imaging plane toward the imaging plane.
