An instrument used by surgeons to determine the suitability of an aneurysm or vascular clip just prior to its implantation. The primary component of the instrument is a test strip which comprises a first compartment, second compartment, and a tapered channel connecting these two compartments. The first compartment contains a colored fluid and means for forcing the fluid from the compartment into the tapered channel. The clip selected is attached to the test strip over the tapered channel. As the fluid is forced into the tapered channel and reaches the clip, the clip's effectiveness in impeding the pressurized fluid flow is observed. The pressure at which the clip fails is indicated on gauge means.
