Abstract: A fenestration (36) piercing the otic capsule bone of the cochlea (34) receives a therapeutic appliance, such as a microactuator (78), plug (92), micropump for drug or therapeutic agent delivery, electrode (102), etc. Disclosed are several different ways of achieving a "water tight" seal between the otic capsule bone and the therapeutic appliance. Also disclosed are specific ways of implanting the therapeutic appliance both with and without a sheath (72) lining the wall of the fenestration (36) formed using specialized surgical burrs (122, 124, 162, 164). The burrs (122, 124, 162, 164) permit safely fenestrating the otic capsule bone adjacent to the scala tympani (44) of the cochlea (34) without damaging the basilar membrane (52) or organ of cordi. The invention disclosed herein may also be adopted for safely fenestrating other areas of the inner ear such as the scala vestibuli (42), bony labyrinth of semicircular canals, or walls of the vestibule, or perhaps even the oval or round windows thereof.

Abstract translation: 穿刺耳蜗（34）的耳状胶囊骨的开窗口（36）接收治疗器具，例如微致动器（78），塞子（92），用于药物或治疗剂递送的微型泵，电极（102）等。公开 是在耳用胶囊骨头与治疗用具之间实现“防水”密封的几种不同方式。 还公开了植入具有和不具有护套（72）的治疗器械的具体方式，护套（72）衬有使用专用手术毛刺（122,124,162,164）形成的开窗（36）的壁。 毛刺（122,124,162,164）允许在耳蜗（34）的鼓阶（44）附近安全开耳状囊膜骨而不损伤基底膜（52）或脐带器官。 本文公开的发明还可以用于安全开窗内耳的其他区域，诸如前庭前庭（42），半规管的骨迷路或前庭壁，或者甚至可以是其椭圆形或圆形窗。
