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).

Abstract: A system and method for monitoring the performance of selected data processing jobs, comparing actual performance against the Service Level Agreement (SLA) to which each monitored job belongs, identifying discrepancies, and analyzing impacts to other jobs in a job stream. The present invention, also referred to as the Automated SLA Monitor (ASM), is a distributed computing platform comprising one or more Production Consoles for extracting job performance data from the production mainframe computers (or production midrange computers in other embodiments), one or more Production Servers for housing databases, one or more Maintenance Workstations for entering and maintaining SLA data, and one or more Client Workstations for presenting selected data to the user.
