Abstract
Systems, devices, and methods for powering and/or controlling active or electrically powered transdermal delivery devices employ a magnetic field blocker such as a ferrous disk between a magnetic coupler element and a battery to counter adverse affects on the battery by the magnetic coupler element.
Claims22
A medical device, comprising:
- a first portion including at least one electrode selectively operable to provide an electrical potential and including at least a first element of a magnetic coupler;
- a second portion including at least one battery cell and including at least a second element of the magnetic coupler, the second element of the magnetic coupler complementary to the first element of the magnetic coupler, the second portion of the medical device selectively removably magnetically coupleable to the first portion of the medical device via a magnetic interaction between the first and the second elements of the magnetic coupler;
- and
- a ferrous element physically carried by one of the first or the second portions, wherein at least one of the first or the second elements is a magnet and the ferrous element is physically positioned between the battery and the magnet to steer a magnetic flux of the magnet away from the battery.

An apparatus, comprising:
- a battery holder configured to hold a battery;
- a first coupling magnet physically coupled to the battery holder and positioned proximate the battery holder;
- and
- a ferrous element positioned between the battery holder and the first coupling magnet to steer a magnetic flux of the first coupling magnet away from the battery holder.
