Leak detection for implantable inflation devices

An implantable inflation device, comprising:

• a fluid reservoir defining a cavity;
• an inflatable member;
• an inflation fluid;
• a pump assembly configured to transfer the inflation fluid from the fluid reservoir to the inflatable member;
• a housing, the pump assembly and at least a portion of the circuit being disposed within the housing;
• and
• a circuit for measuring electrical resistance, the circuit being configured to measure an electrical resistance between the inflation fluid within the implantable inflation device and a portion of a body of a patient in which the implantable inflation device is implanted,
• wherein the circuit includes a first electrical contact disposed on an exterior surface of the implantable inflation device and a second electrical contact disposed in a fluid passageway of the implantable inflation device,
• the electrical resistance measured by the circuit is an electrical resistance between the first electrical contact and the second electrical contact,
• the fluid reservoir is fluidically coupled with the pump assembly via a first tubular member,
• the inflatable member is fluidically coupled with the pump assembly via a second tubular member,
• the pump assembly is configured to fluidically isolate the fluid reservoir and the first tubular member from the inflatable member and the second tubular member,
• the housing is the first electrical contact, the housing including an electrically conductive material.
