Publication number: 20150005750Abstract: Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.Type: ApplicationFiled: April 29, 2014Publication date: January 1, 2015Applicant: Tear Film Innovations LLCInventors: Brian S.

Publication number: 20130090680Abstract: A minimally invasive dilation device includes a stylus, a plurality of rigid arms radially arrayed about the stylus, and a dilating member positioned between the stylus and the arms. An outer flexible sleeve may be circumferentially secured to the arms, lying within or without the plurality of arms. An inner mesh may surround the stylus and dilating member. The device may be introduced into tissue toward a targeted area, while in a closed configuration. The dilating member may be a balloon or a cannula. During dilation, the arms are pushed radially outward, expanding the device and dilating the surrounding tissue. A cannula may be inserted inside the plurality of arms to keep the arms in an open configuration, and the stylus and inner mesh may be withdrawn, providing an open passageway through the device to the targeted area. The device may be used with a neural monitoring system.Type: ApplicationFiled: November 29, 2012Publication date: April 11, 2013Applicant: OSTEOMED LLCInventors: Ephraim Akyuz, Kabir Gambhir, Corbett Stone
