Abstract
A tubing set and method for use with a system for providing pressurized fluid from a fluid source to a surgical site. The system includes a fluid source, a length of flexible tubing having one end connected to the fluid source and another end connected to a surgical instrument, and a peristaltic type pump into which a middle portion of flexible tubing is positioned so that the peristaltic type pump can pump fluid from the source to the surgical instrument by bearing on the exterior of the tubing. The improved tubing set also includes a by-pass section of tubing connected between the tubing inlet and the tubing outlet in parallel with the middle portion of the flexible tubing. The by-pass section provides pressure relief to the system so that pressure in the tubing will not build up distally of the location of the peristaltic pump.
