Abstract
A medical implant includes an implant component configured to be implanted in a patient, an electrode array, an energy storage device, and a power management unit. The electrode array includes at least two electrodes spaced apart on the implant component. The energy storage device and power management unit are inside the implant component. The power management unit is operative to control electrical stimulation of the electrode array by current supplied by the energy storage device to be at a level which at least reduces formation of a biofilm on at least part of the implant component while implanted in the patient.
Claims17
A medical implant comprising:
- an implant component configured to be implanted in a patient;
- an electrode array comprising at least two electrodes spaced apart on the implant component;
- an energy storage device inside the implant component;
- and
- a power management unit inside the implant component and operative to control electrical stimulation of the electrode array by current supplied by the energy storage device to be at a level which at least reduces formation of a biofilm on at least part of the implant component while implanted in the patient,
- a first set of the electrodes of the electrode array are spaced apart on a surface of the implant component;
- a second set of at least one of the electrodes, which is not among the first set of the electrodes, is spaced away from the first set of electrodes;
- and
- the power management unit is operative to control current density flowing from the first set of electrodes to the second set of the at least one of the electrodes through intervening tissue of the patent and/or to control current density flowing from the second set of the at least one of the electrodes to the first set of electrodes through intervening tissue of the patent.
