notes: label: Description
content: Cross circulation SigmaMotor finger pump, model TMI, with a Leland motor. Finger pumps of this sort were used in several cutting-edge medical procedures. Dr. C. Walton Lillehei used one in his open-heart operations at the University of Minnesota. Dr. William Kolff in Cleveland used them for more accurate blood flow with his artificial kidney (dialysis) machines. The unique design of the T-8 pump uses metal ‘fingers’ that are activated by a cam to progressively squeeze the tubing, gently pushing the liquid through the pump head. SigmaMotor was incorporated in New York in 1951, as an allied corporation of E & M Enterprises, Inc., a special machine manufacturer.
