1. A wearable infusion pump system, comprising:
- a disposable and non-reusable pump device including a drive system to dispense medicine from the pump device, the pump device having a first electrical connector that is externally accessible;
a reusable controller device removably attachable to the disposable and non-reusable pump device, the controller device including a second electrical connector that is engageable with the first connector to provide electrical communication between control circuitry of the controller device and the drive system of the pump device; and
a water-resistant seal device arranged proximate to the first and second electrical connectors when the controller device is removably attached to the pump device.

Abstract
Some embodiments of an infusion pump system may include a construction that is resistant to external contaminants, such as precipitation, water splashes, sweat and the like. In particular embodiments, the infusion pump system can include a pump device that is removably attached to a controller device to provide an electrical connection therebetween. In such circumstances, the infusion pump system can be assembled as a sealed construction that protects the electrical connection between the pump device and the removable controller device.

11. A method of connecting components of an infusion pump system, the method comprising:
-
preparing a pump device for use with a controller device, the pump device including at least a portion of a drive system to dispense medicine from the pump device, the controller device including control circuitry to communicate control signals to the drive system of the pump device; removably attaching the pump device with the controller device so that a first electrical connector of the pump device engages a second electrical connector of the controller device; and compressing a water-resistant seal device between the pump device and the controller to resist migration of water toward the first and second electrical connectors. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A contaminant-resistant infusion pump assembly, comprising:
-
a pump device including;
a drive system to dispense a medicine from the pump device, a pump housing to enclose at least a portion of the drive system, and a first electrical connector that is externally accessible along the pump housing;a seal device attached to an external surface of the pump housing proximate to the first electrical connector; and a controller device removably attached to the pump device, the controller device including;
a user interface having a display device and at least one button, control circuitry to communicate with the drive system of the pump device, a controller housing to enclose at least a portion of the control circuitry, and a second electrical connector is engaged with the first connector to provide electrical communication between the control circuitry and the drive system,wherein the seal device is arranged between a surface of the pump housing and an opposing surface of the controller housing to resist migration of external contaminants toward the first and second electrical connectors. - View Dependent Claims (23, 24, 25, 26)
