Abstract
A removal tool for atraumatically removing a removable fitting from a hearing device inserted deeply in the ear canal comprises a housing adapted to be grasped in the hand and a plurality of flexible members partially positioned in the housing and extending from the housing. The members have an outwardly flared portion at a distal portion of the member. At least one member includes an engagement element positioned at the flared distal portion of the member for engaging a removal element on the fitting. The tool also comprises a mechanism for engaging the engagement element with the removal element for removal of the fitting independent of a radial orientation of the housing with respect to the hearing device.
