New Class of Insulin Delivery Device Approved for Use with Humalog, NovoLog
On July 26, the U.S. Food and Drug Administration (FDA) approved the Finesse insulin patch-pen, a new type of insulin delivery device, for use with NovoLog
rapid-acting insulin. In January, the device was granted FDA clearance and

boluses of either 1 or 2 units of insulin are delivered by squeezing the two
buttons located on either side of the device. (To prevent accidental boluses,

insulin pumps with the non-electronic simplicity, safety, and affordability of
According to diabetes blogger Bernard Farrell, the manufacturer is currently working out some supply and design issues, and at present there is no
definitive release date for the device.
