Cannulation and continuous cross-sectional area measurement of small blood vessels.

Abstract

Techniques have been developed for the study of isolated small arteries. To pressurize and perfuse segments of these vessels, a cannula with a low resistance to flow was developed. This cannula consisted of two concentric micropipettes. The end of a vessel segment was sucked into the inner pipette and clamped by applying subatmospheric pressure on the outer… (More)
