Patent ID: 7313245

Claim:
An intracanal shield for positioning entirely in the ear canal and capping the cavity of said ear canal, comprising: a retention ring adapted to conform to the wall of the ear canal cavity, a central porous member disposed within the retention ring having pores sized for allowing air to pass through said porous member to provide a circulated air flow in the ear canal while preventing passage of fluids and solids therethrough, wherein said intracanal shield, when fitted in said retaining manner in the ear canal cavity and positioned laterally with respect to a miniature hearing device medically positioned in close proximity to the eardrum, protects said hearing device against penetration of fluids and debris through said porous member while allowing air-borne sounds to reach said hearing device, wherein said intracanal shield is separate from said canal hearing device for independent insertion and removal while said hearing device is positioned in-situ.
