Abstract:
In various embodiments, approaches to calibrating an implantable drug-delivery device feature a drug reservoir, an expandable electrolysis chamber, and an integrated strain gauge using a refill apparatus having one or more pumps, one or more refill reservoirs, an outlet fluid channel fluidically connected to the refill reservoir(s), and a needle having a lumen in fluid communication with the outlet fluid channel include inserting a needle into a refill port of the implantable drug-delivery device, monitoring a pressure change within the device, monitoring a pressure level of one or more components of the implantable drug-delivery device, and calibrating the monitored pressure level of the component(s) of the implantable drug-delivery device to the monitored pressure level of the outlet fluid channel.
