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 10):
A cannula system for accessing a blood mass in the brain of a patient, said cannula system comprising:\n a cannula comprising a cannula tube with a proximal end and a distal end and a lumen extending from the proximal end to the distal end; and a camera secured to the proximal end of the cannula, with a portion of the camera overhanging the lumen; an obturator comprising an obturator shaft having a proximal end and a distal end, and an obturator tip disposed on the distal end of said obturator shaft, said obturator being slidable within the cannula tube, and positionable within the cannula tube such that the proximal end of the obturator shaft extends proximally out of the cannula proximal end while the obturator tip extends out of the cannula distal end, wherein the obturator shaft has a transverse cross section smaller than the lumen of the cannula; wherein the portion of the camera overhanging the lumen is spaced proximally from the proximal end of the cannula, and the obturator tip is configured to pass into the cannula lumen while the portion of the camera portion of the camera overhanging the lumen is in place overhanging the lumen.
