Latest Patents

One of Petithory's latest patents is an implantable pump with a reservoir level detector. This innovative device includes a base plate and a can that form the pump housing. The base plate bottom divides the housing into a first electronics chamber and a second chamber. A bellows mechanism is connected to the base plate and is located within the second chamber. This mechanism features an expandable sidewall and a bottom plate, dividing the second chamber into a medicament receiving portion and a non-medicament-receiving portion. An intermediate plate is also present within the medicament-receiving portion. A coil is positioned in a recess on the lower surface of the base plate, spaced from the internal wall of the recess. The fluid remaining in the implantable pump can be monitored by energizing the coil, which generates a primary magnetic field. A secondary magnetic field, dependent on the position of the bottom and intermediate plate of the bellows mechanism, couples back to the primary field, affecting the electrical characteristics of the coil. The amount of fluid remaining in the reservoir is determined based on the resulting changes in the electrical characteristics of the coil.
