Embodiment Construction

[0023] The following is a description of preferred embodiments of the present invention. It should be appreciated, however, that other embodiments will be apparent to those skilled in the art.

[0024] figure 1 A side view of the device assembly 1 is shown in . In a preferred embodiment, the main components of the device 1 are: a front body 10 , a rear body 20 , a removable cover 30 and a handle 40 . In the preferred embodiment, the device reduces the pressure in the ear canal slightly enough to cause the eardrum to flex outward, towards the distal surface of the removable shell 34 . There are several ways of reducing pressure. For example, in a preferred embodiment, a commercially available insufflator bulb is connected to the vacuum connection 11 . By squeezing the bulb before inserting the device into the ear canal and releasing the bulb after the device has been inserted, the pressure in the ear canal will be reduced sufficiently to cause the eardrum to bend towards th...

Abstract

A device for substance delivery to and / or extraction from the tympanic cavity, comprising: a housing, having a distal surface, a proximal surface that is opposite to the distal surface, and a circumscribed surface that connects the distal surface and the proximal surface; at least one piercing element having at least one proximal piercing end and at least one distal piercing end, disposed within the housing in such manner that the at least one distal piercing end is / are generally facing the distal surface of the housing; and a means for flexing the tympanic membrane toward the distal end of the at least one piercing element.

Description

[0001] Inventors: C. Pfeffer, G. B. Kenny, L. Rosenbloom [0002] Assignee: Antemipanic Co., Ltd. [0003] Cross References to Related Applications [0004] This application claims priority to US Provisional Patent Application No. 61 / 251,792. technical field [0005] The present invention relates generally to otological devices and methods of treating various ear-related disorders, and more particularly to the delivery of drugs into the tympanic cavity. Background technique [0006] The devices and methods of the present invention involve delivering medication to the middle and / or inner ear and evacuating fluid, if present, in the tympanic cavity. The device and method can be used, for example, to treat and / or prevent various ear-related diseases, such as acute otitis media. [0007] It is often necessary to deliver various types of drugs into the drum cavity. This drug can be used directly to treat diseases of the middle and inner ear. For example, a medically effectiv...
