1. A portable infusion pump, comprising:
- a delivery mechanism adapted to facilitate a delivery of a medicament to a user;
a memory adapted to store one or more parameters relating to the delivery of the medicament;
a communications device adapted to receive information from a continuous glucose monitor; and
a processor functionally linked to the delivery mechanism and the memory and to the communications device to obtain the information from the continuous glucose monitor, the processor configured to;
monitor the information received from the continuous glucose monitor;
determine from the information received from the continuous glucose monitor that an additional amount of the medicament should automatically be delivered to the user;
review at least one parameter of the one or more parameters stored in the memory that relates to mitigating risk in automatically delivering the medicament based on the information received from the continuous glucose monitor;
determine whether the additional amount of the medicament can be delivered to the user in view of the at least one parameter that relates to mitigating risk; and
cause the delivery mechanism to deliver the additional amount of the medicament if it is determined that the additional amount of the medicament can be delivered to the user,wherein the at least one parameter that relates to mitigating risk in automatically delivering the medicament includes an excess medicament amount limit defining a maximum amount by which the medicament delivered to the user can be increased, and determining whether the additional amount of the medicament can be delivered includes comparing the additional amount of the medicament to the excess medicament amount limit.

Abstract
A portable infusion pump can communicate with glucose monitor, such as a continuous glucose monitor (CGM), to receive continuous feedback relating to a user'"'"'s blood glucose level during insulin or other medicament therapy and can automatically deliver insulin to a user when the CGM data indicates a need for additional insulin. Due to potential unreliability in the correlation of the CGM data to the user'"'"'s actual blood glucose level, risk mitigation can be employed to limit the amount of extra insulin that can be delivered by the pump in response to the CGM data.
