An element for a phonomicrosurgical modular glottiscope system comprises a proximal end; a distal end; a pair of opposing curved sides intersecting at an apex line; a substantially planar base, and internal channels disposed within the base. The base plate is removably attached to the pair of curved sides, and the base and curved sides define a lumen extending from the proximal end to the distal end. The internal channels include a first internal channel that provides illumination to the distal end and a second internal channel that provides aspiration to the distal end. In operation, the distal end of the element is inserted into a body cavity and the lumen provides visualization of the distal end and access to the distal end for tools inserted into the lumen from the proximal end. A method of manufacturing the element is also disclosed.

A universal modular glottiscope system includes a set of differently dimensioned elongate tubular elements for insertion into a patient's larynx for laryngoscopic procedures or intubation. Each tubular element has a substantially triangular cross-section distally defined by a substantially planar base and two curved sides which intersect at an apex line and may have varying curvature between the apex line and the base. A distal end opening is defined by an intersection of the cross-section with an imaginary plane at a selected angle to the longitudinal direction of the tubular element. At the proximal end of each tubular element, which is D-shaped in configuration and wider than the distal end, is provided a pair of opposed end slots intermediate the apex line and the base. The planar base is detachable. Above the slots, adjacent the proximal end of each tubular element, is a standardized handle-attachment fitting.

An adjustable supraglottiscope designed to be used in the supraglottic larynx is disclosed, in particular, an improved apparatus for endoscopic surgery in the supraglottis and the lower pharynx is disclosed by having at least one blade that is at least as wide as the normal, human epiglottis in its natural position within the body. The blades of the supraglottiscope have a length to width ratio that is about one-half of that found in conventional instruments. This unique ratio enables a wider exposure of the supraglottic larynx and lower pharynx. Methods of performing surgery on the supraglottic larynx of a patient are also described.

A voice prosthesis includes a voice actuator for generating a signal to be modulated into speech and a neural interface for receiving a signal indicative of neural activity. A signal processing system in communication with both the neural interface and the voice actuator is configured to provide the voice actuator with a control signal representative of the neural activity.
