1. An infusion pump system, comprising:
- a delivery mechanism adapted to facilitate delivery of medicament to a patient;
memory adapted to store parameters relating to the delivery of 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;
cause the delivery mechanism to deliver medicament to the patient according to therapy parameters determined based on the information from the continuous glucose monitor;
determine from user-defined input that the patient is going to take or has taken a medication;
suspend delivery of medicament according to the determined therapy parameters for a suspension period in response to the determination that the patient is going to take or has taken a medication;
cause the delivery mechanism to deliver medicament according to a default medicament delivery schedule stored in memory during the suspension period; and
resume causing the delivery mechanism to deliver medicament to the patient according to the determined therapy parameters following the suspension period, andwherein the processor is further configured to receive a duration for the suspension period entered through a user interface in communication with the processor.

Abstract
A portable infusion pump can communicate with 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. Because patient behavior can interfere with the accuracy and efficacy of such closed loop or semi-closed loop therapy, a system can employ various mechanisms for manual temporary suspension of closed-loop therapy when a patient is aware that current or future behavior may inhibit therapy.
