The total U.S. market for insulin pumps can be segmented by pump type, yielding three segments: traditional insulin pumps, patch insulin pumps and simple insulin pumps. In 2016, the largest segment in the total insulin pump market was the traditional pump segment. Traditional pumps account for such a large portion of the market because they are a much more established market, relative to the patch pump and simple pump markets, which were launched in the U.S. in 2005 and 2012, respectively. It is expected that traditional pumps will maintain their dominance over the forecast period, despite the growing market share of patch pumps and simple pumps. Patch pumps are an attractive therapy option for the proportion of the patient population that values the wireless features and significant cost savings on the initial investment of the device, relative to traditional pumps. Although Insulet Corporation currently holds a monopoly in the U.S. market, Cellnovo and other competitors are expected to launch patch pump products over the forecast period and contribute to increased device uptake among the insulin-dependent diabetic population.
Traditional insulin pumps, often referred to as durable pumps, offer constant and finer delivery of insulin to maintain precise control of glycemic levels. Traditional pumps feature a reservoir of insulin connected to the patient through plastic tubing and a cannula, referred to as an infusion set. A small computer controls the dosage, and is pre-programmed specifically for the patient. The insulin pump is used to deliver both basal and bolus insulin. Basal insulin is delivered continuously at a rate set by the user specific to the time of day. Bolus insulin is injected prior to eating based on what the patient plans to eat and their current blood glucose level. Infusion sets are typically replaced once every three days, while insulin reservoirs are typically replaced once every two to three days. New technological innovations in the traditional pump market include pumps with built-in continuous glucose monitoring (CGM), low glucose suspension algorithms and touchscreen interfaces.
