Abstract

A system and method for dilating a Eustachian tube of a patient is disclosed. The device includes a protective sheath, a flexible endoscope and a balloon dilation catheter. The protective sheath includes an endoscope lumen and a balloon dilation catheter lumen. The balloon of the balloon dilation catheter is a low profile balloon particularly useful for dilating the Eustachian tube, and in particular, the Eustachian tube of a pediatric patient. The method involves advancing the balloon dilation catheter through a nasal passage of the patient to dilate a portion of the Eustachian tube.

Description

technical field [0001] The present invention relates to methods and systems for accessing and treating target tissue regions and Eustachian tubes within the middle ear. Background technique [0002] Referring to FIGS. 1-2 , the ear 10 is divided into three parts: the outer ear 12 , the middle ear 14 and the inner ear 16 . The outer ear 12 consists of the pinna 18 and ear canal 20 which collect sound and direct it toward an eardrum 22 (also called eardrum) at an inner end 24 of the ear canal 20 . Middle ear 14 is located between outer ear 12 and inner ear 16 and is connected to the back of the throat by Eustachian tube 26, which acts as a pressure equalizing valve between ear 10 and the sinuses. The Eustachian tube 26 terminates at a distal opening or mouth 28 in the nasopharyngeal region 30 of the throat 32 . In addition to the eardrum 22, the middle ear 14 is composed of three small ear bones (ossicles): malleus 34 (hammer), incus 36 (anvil), and stapes 38 (stirrup). The...
