About 1965, we began hearing of the problems being experienced with a spring driven portable pump which had just come on the market. We thought a battery driven pump would be a better approach and developed the ML line.
These were small flow chemotherapy pumps designed to be worn on a harness for continuous infusion at low rates. The first of these were shipped in 1965. After a few years of mediocre sales, the marketing of these unites was spun off to Cormed Inc., headed by Gerald Hilger, a longtime employee of SigmaMotor. Under his ownership, sales were expanded tremendously, and the company was sold to C.R. Bard Inc.
While the medical applications of our pumps were being developed, we had not neglected the laboratory field which continued to be the foundation of our business. New models were developed, and new applications pursued.
In 1967 we discovered that a few of our laboratory pumps were being used to obtain samples from waterways and sewers for pollution analysis. We felt this was an ideal new use for tubing pumps and proceeded to develop a small line of pollution sampling units. The first of these was shipped in 1968. Today American Sigma Inc. headed by William Hungerford is the second largest supplier of pollution sampling equipment in the world.
In summary, in the production area, I think SigmaMotor has been quite innovative for a small company. We were able to develop the first blood pump for open heart surgery, the first infusion pump, the first blood pump used in kidney dialysis, the first of the tumor perfusion units, and we improved considerably on the portable infusion pumps.
In conclusion, a brief word on the recent developments of the Company may be appropriate. After college, both my sons, Roger and William came to work for SigmaMotor. Both were interested in primarily in marketing. Both became salesmen. Over a period of five or six years Roger took over the medical part of the company and Bill took the industrial and pollution areas. Since I was approaching retirement age I was concerned about succession. I was convinced that neither one would be happy working for the other. After considerable thought and discussion, we decided to do a double spin off. Fortunately, both parts of the company were about equal, so an equitable result was accomplished. In the ensuing five or six years both parts have grown tremendously. Roger chose to sell to Smith & Nephew, but Bill is continuing to operate and will be building a new plant in Medina this year.
Since neither of the boys needed or wanted the machine shop, I kept it and we are now operating as a jobbing machine shop. We are one of the suppliers of Smith & Nephew.
