Implantable Insulin Pumps

Implantable insulin pumps are surgically implanted under the skin of the abdomen. The pump delivers small amounts of insulin throughout the day and extra amounts before meals or snacks. Users can control doses with a remote control unit that prompts the pump to give the specified amount of insulin. The pump is refilled with insulin every two to three months.

This approach for taking insulin is under development.
