Valeritas Holdings Inc. has developed the V-Go Wearable Insulin Delivery Device (V-Go) for patients with Type 2 diabetes.
According to the company's Web site, V-Go is a disposable device indicated for "continuous subcutaneous infusion of insulin over 24 hours at preset rates and on-demand bolus dosing in two-unit increments in adult patients requiring insulin."
Part of the small, lightweight wearable is an injection-molded cartridge made of TOPAS cyclic olefin copolymer (COC) from TOPAS Advanced Polymers. “TOPAS COC fills an important role in the cartridge system of the V-Go insulin delivery device,” stated Geoffrey Jenkins, executive vice president of manufacturing and research and development for Valeritas, in a press release. “We find it to be highly stable in contact with the drug and it has great optical clarity; moreover, it offers good injection molding characteristics with excellent dimensional stability and minimal shrinkage.”
