A method of deploying a prosthesis includes restraining the prosthesis within a distal end of a sheath. A slide ring of a handle is rotated to initiate retraction of the sheath. In this manner, the prosthesis is initially very gradually released. The slide ring is then slid to complete retraction of the sheath and to deploy the prosthesis. In this manner, the sheath is easily and quickly retracted thus rapidly completing deployment of the prosthesis. Rapid deployment of the prosthesis facilitates faster procedure times, thus minimizing the period of time during which blood flow is occluded.

A time-partitioned system for accounting for processor time consumed by operating system services provided on behalf of an application runs in a real-time environment. The time utilized by the operating system is treated as application processing time, rather than viewing the resultant processor time consumed as an operating system overhead. Each application consists of one or more threads. A time budget is assigned to each thread and to each interrupt. The processor time consumed by the operating system when executing on behalf of a thread or interrupt is charged back to the application or interrupt as part of the application's time budget. Operating system overheads and processor interrupts are thus accounted for accurately enough to determine a schedule for the applications that is enforceable by the operating system at run time.
