  • Patent number: 9682169
    Abstract: The present invention provides hydrogels and compositions thereof for vocal cord repair or augmentation, as well as other soft tissue repair or augmentation (e.g., bladder neck augmentation, dermal fillers, breast implants, intervertebral disks, muscle-mass). The hydrogels or compositions thereof are injected into the superficial lamina propria or phonatory epithelium to restore the phonatory mucosa of the vocal cords, thereby restoring a patient's voice. In particular, it has been discovered that hydrogels with an elastic shear modulus of approximately 25 Pa are useful in restoring the pliability of the phonatory mucosa. The invention also provides methods of preparing and using the inventive hydrogels.

  • Publication number: 20130303842
    Abstract: Compositions comprising aortic material and methods for using harvested blood vessels (e.g., arteries or veins e.g., aortae) graft procedures, e.g., for restoring and repairing luminal structures (e.g., in the aerodigestive tract, such as the larynx, pharynx, and esophagus); as tissue fillers (e.g., injectable morselized blood vessel tissues, for use in cosmetic applications and functional sphincter enhancement); and as biological structural supports (e.g., intact portions of aortae, for use in repairing abdominal wounds, anastomoses, bony repairs, and the heart).

  • Patent number: 6955645
    Abstract: 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.

  • Patent number: 5092314
    Abstract: 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.
