Abstract
A method for detecting an electrode fault in a cochlear prosthesis. A voltage between the implanted electrode and a reference node is measured. It is then determined whether the voltage measured has been affected by an electrical leakage path between the electrode and a power supply node.

2. A method for detecting an electrode fault in a cochlear prosthesis, the method comprising:
-
in a first phase, establishing a first current flow path from a first node to a first implanted electrode, from the first implanted electrode through interposed tissue to a second implanted electrode, and from the second implanted electrode to a second node, and obtaining a first voltage measurement between the second implanted electrode and a reference node; in a second phase, establishing a second current flow path from the first node to the second implanted electrode, from the second implanted electrode through interposed tissue to the first implanted electrode, and from the first implanted electrode to the second node, and obtaining a second voltage measurement between the first implanted electrode and the reference node; and comparing the first voltage measurement with the second voltage measurement to detect the presence of a leakage path. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A method for detecting an electrode fault in a cochlear prosthesis, the method comprising:
-
open circuiting an implanted electrode so that no current flow paths are provided through the implanted electrode; and measuring a voltage between the implanted electrode and at least one reference node to determine whether a leakage path between the implanted electrode and a power supply node exists. - View Dependent Claims (13, 14)
