From: Involvement of the Endothelin System in Experimental Critical Hind Limb Ischemia
Diagram of the experimental procedure. In grey: the arterial system of the rat hind limb. The common iliac artery was temporarily clamped, a catheter was inserted through the femoral artery, and the microspheres then were injected into the internal iliac artery. The femoral artery then was ligated and excised. The muscles colored in grey represent two of the muscles tested for functional evaluation; the third muscle (biceps femoris) being out of view on the other side of the hind limb.
