Embodiment Construction

[0058] In the following specification, where a range of values ​​is provided, each intervening value between the upper and lower limits of that range, up to the tenth of the unit of the lower limit, is also specifically described unless the context clearly dictates otherwise. Each smaller range between any stated value or intervening value in a stated range and any other stated or intervening value in that stated range is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included or excluded from the stated ranges, and each range is also encompassed within the invention, with either, or none, of the limits or limits in each stated range. Both values ​​are included in the smaller ranges, limited only by any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the invention.

Abstract

The present invention discloses a variable direction of view endoscope which can be positioned at desired locations within the ear, nose, throat, paranasal sinuses or cranium to accomplish visualization. A method of use includes introducing the variable direction of view endoscope into a nasal cavity with the endoscope adjusted to a first direction of view between about 0 degrees and about 15 degrees relative to a longitudinal axis of the endoscope. A therapeutic device is introduced into the nasal cavity and the endoscope is adjusted to a second direction of view directed toward the sinus opening or passageway. The method also includes advancing the therapeutic device into or through the sinus opening and viewing at least one of the sinus opening or passageway or the therapeutic device using the endoscope adjusted to the second direction of view.

Description

[0001] Cross references to related patent applications [0002] This patent application claims priority to Provisional Patent Application Serial No. 61 / 084,949, filed July 30, 2008, the contents of which are incorporated by reference. technical field [0003] The present invention relates generally to medical devices and methods, and more particularly to devices and methods for facilitating endoscopic viewing within the ear, nose, larynx, paranasal sinuses, or braincase. Background technique [0004] Functional endoscopic sinus surgery (FESS) is currently the most common type of surgery used to treat chronic sinusitis. In a typical FESS procedure, an endoscope is inserted into the nostril along with one or more surgical instruments. The surgical instruments are then used to cut tissue and / or bone, cauterize, suction, and the like. In most FESS procedures, the natural ostium (eg, opening) of at least one paranasal sinus is surgically enlarged to improve drainage from the si...
