摘要： An exemplary self-curling cochlear electrode lead includes a flexible body formed of a flexible insulating material, a shape memory polymer element that is embedded within the flexible body and that is configured to cause the self-curling cochlear electrode lead to transition to a curved spiral shape so as to conform with a curvature of a human cochlea when a temperature of the shape memory polymer element reaches a transition temperature, a plurality of electrode contacts arranged along a side of the flexible body, and a plurality of wires embedded within the flexible body and configured to electrically connect the plurality of electrode contacts to at least one signal source. Corresponding methods of manufacturing a self-curling cochlear electrode lead are also described.

摘要： An exemplary insertion management system is configured to direct a cochlear implant to apply electrical stimulation by way of a first electrode disposed on an electrode lead that is being inserted into a cochlea of a recipient, direct the cochlear implant to record, while the electrical stimulation is being applied by way of the first electrode, a differential voltage signal representative of a differential voltage between a second electrode and a third electrode both disposed on the electrode lead, the second and third electrodes different than the first electrode, determine, while the differential voltage signal is being recorded, that a signal characteristic of the differential voltage signal changes by at least a threshold amount, and determine, based on the signal characteristic changing by at least the threshold amount, that a distal end of the electrode lead is positioned within a threshold distance of a basal turn of the cochlea.
