Roger Hungerford founded Talis Equity in 2009 to further invest in transformative medical and software technology after three decades leading SIGMA, an intravenous infusion pump designer and manufacturer.
SIGMA was bought and sold twice by Roger (founder, CEO and lead designer) and his management team.
SIGMA I was formed in 1982 and sold in September 1987 to Smith's Industries of London, for $8.5 million.
repurchased SIGMA in 1992 for $4 million and later resold 40% of it to Baxter Healthcare in April 2009 for $100 million, followed by the remaining 60% in April 2012 for a further $149 million.
SIGMA became the technological leader in "smart" IV pumps during the period of 2005 to 2012, eventually installing nearly 100,000 pumps per year in 2011 and 2012 - all time industry records.
Smart IV pumps included embedded software artificial intelligence systems that could detect root causes of fatal Adverse Drug Events (ADEs) from nurse/doctor keypad entries.
licensed the first generation smart IV pump system from Dr. Nat Sims at Massachusetts General Hospital
II smart system eventually designed by Roger
employed four separate ADE prevention systems, the first of its kind.
During the three year period of 2009 to 2012, Roger
existing team and key new hires worked closely with Baxter.
Production scaled to 2200 pumps per week with a very difficult to manufacture product.
The recalled Baxter Colleague pump fleet was largely replaced, protecting Baxter's huge IV set/solution business.
SIGMA, now Baxter, continues to remain in Medina, NY, renting space from The Olde Pickle Factory industrial park, where Roger
and Talis Equity
are also located.
Baxter has been an excellent community partner in Medina and has taken extensive care of its employees and local suppliers.
