An endoscope may include a needle and a scope, which may optionally be contained in an elongated shaft. The endoscope may further include a handle comprising at least one button, a visualization component, a reservoir configured to contain a composition, and a dispensing mechanism. The at least one button, the needle, the reservoir, and the dispensing mechanism may be operably linked to cause the composition to be dispensed from the reservoir through the needle to a portion of an ear. A method for using such an endoscope may include inserting the endoscope into a portion of an ear, using the visualization component to visualize the portion of the ear, and pressing the at least one button to dispense the composition from the reservoir through the needle to the portion of the ear.

There is described an apparatus comprising a first optical element, a second optical element and a spacing element for use with a mobile user device. The first optical element is configured to provide an image of an object to an intermediate image plane and the second optical element magnifies the image to provide a final image in a final image plane in which a camera aperture of the device is supported. The spacing element maintains a fixed separation between the object and the first optical element. Image magnification is achieved while also providing a space for tool access. Mirrors may be used to divert the optical path, allowing the optical path to be folded for more compact apparatus. A third optical element disposed at the intermediate image plane may be used to reduce vignetting effects in the final image.

A speculum includes, in part, an iris aperture. The iris aperture includes, in part, an actuator and a multitude of blades. Each blade is adapted to vary the opening of the aperture in response to an applied force. Each blade includes, in part, a wing extending outwardly from the aperture. Each wing has a base that is larger than the wing's tip. Each wing has a curved surface along at least a portion of the wing's height. In one embodiment, the at least portion of the wing's height is the entirety of the wing's height. Each blade and its associated wing are optionally formed from the same material. Therefore, a single piece of the material may be shaped to include both the blade and its associated wing. The blades may optionally be made from a material that is different from the material from which the wings are made.

The present disclosure relates to a device and method for detection and compensation for an oblique ear-probe insertion in especially hearing testing diagnostic setups. More particularly the disclosure relates to detecting an oblique probe insertion from an ear-probe measurement and estimated characteristic impedances and compensate for its effect on the ear-canal reflectance.

A seeker device for facilitating access to a desired location within an ear, nose, throat or other location in a body may include a proximal shaft, an elastic distal portion, and an atraumatic distal tip. The elastic distal portion has a default shape with at least one curve to facilitate advancement of a distal end of the elastic distal portion through various anatomical passageways, toward the desired location. In some embodiments, the seeker device may be paired with a dilator device, to perform a dilation procedure on an anatomical structure in the ear, nose, throat or other part of the body. In other embodiments, the seeker device may be paired with a flexible endoscope, to facilitate visualization of an anatomical structure or area.

A system for self-imaging a body portion includes a self-imaging device and an ancillary device that is attachable to the self-imaging device. The self-imaging device has a base member, a camera located within the base member and a guide element for transmitting light along a path extending between the camera and an exposed tip of the guide element that opens out of the self-imaging device at a given side of the device. The ancillary device is arranged to attach to the self-imaging device at said same given side while substantially not obstructing incoming light arriving towards the self-imaging device from being transmitted via the guide element towards the camera.
