Calibra Medical out of Redwood City, CA has received FDA approval to market its Finesse insulin patch-pen. Earlier this year, Bernard Farrell over at his Diabetes Technology Blog had a chance to get a closer look at the fully mechanical device.
The design itself is slim enough that it should be invisible under most clothing. It contains a reservoir that holds 200 units of insulin.
To dispense insulin you simply squeeze the two small buttons on both sides of the Finesse, the unit clicks with each press so you can count the number of units delivered. There’s an interlocking mechanism, so both buttons must be pressed before any insulin is bolused, this is designed to avoid accidental dispensing of insulin. It’s a bolus-only device, so users will still need shots of long-acting insulin.
