1. A method, comprising:
at least partially inserting a stimulating assembly into a cochlea of a recipient of an implantable medical device, wherein the stimulating assembly comprises a plurality of electrodes;
successively sourcing current via at least a subset of the plurality of electrodes;
in response to each sourced current via one of the plurality of electrodes, sinking the sourced current via at least one extra-cochlear electrode;
in response to each sourced current, disconnecting other electrodes of the plurality of electrodes that are not used for sourcing the current;
in response to each sourced current via the one of the plurality of electrodes, measuring a voltage at a plurality of the other electrodes of the plurality of electrodes while the other electrodes of the plurality of electrodes are disconnected;
collecting the voltages measured at the other of the plurality of electrodes of the stimulating assembly obtained in response to each sourced current to generate a plurality of voltage sets; and
analyzing relative magnitudes of the voltages within the plurality of voltage sets to detect the at least one of a fold or a buckle in the stimulating assembly.
 
13. A system comprising:
a stimulating assembly configured to be at least partially inserted into a cochlea of a recipient of an implantable medical device, wherein the stimulating assembly comprises a plurality of electrodes; and
an event detection processor configured to:
successively source current via at least a subset of the plurality of electrodes;
in response to each sourced current via one of the plurality of electrodes, sink the sourced current via at least one extra-cochlear electrode;
in response to each sourced current, disconnect other electrodes of the plurality of electrodes that are not used for sourcing the current;
in response to each sourced current via the one of the plurality of electrodes, measure a voltage at a plurality of the other electrodes of the plurality of electrodes while the other electrodes of the plurality of electrodes are disconnected;
collect the voltages measured at the other of the plurality of electrodes of the stimulating assembly obtained in response to each sourced current to generate a plurality of voltage sets; and
analyze relative magnitudes of the voltages within the plurality of voltage sets to detect the at least one of a fold or a buckle in the stimulating assembly.
