Title: Bruce J Sand: Innovator in Collagen Treatment Technologies
Introduction
Bruce J Sand is a notable inventor based in Hidden Hills, CA (US). He has made significant contributions to the field of medical technology, particularly in collagen treatment methods. With a total of 5 patents to his name, Sand's work focuses on innovative approaches to tissue treatment and reshaping.
Latest Patents
Among his latest patents is a "Collagen treatment apparatus," which describes a method and apparatus for controlled thermal shrinkage of collagen tissue through irradiation with coherent energy in the wavelength band of 1.80 to 2.55 microns, as generated by a laser. This invention has specific applications in ophthalmological corneal reshaping. Another significant patent is a method for shrinkage of collagen tissue by applying coherent infrared energy, where the threshold shrinkage temperature is substantially reduced by using a reagent such as lysozyme prior to heating. This method is particularly beneficial in ophthalmology for modifying the shape of the cornea and is enhanced by utilizing a corneal collagen shield as a carrier and delivery agent for the reagent and an admixed anesthetic. Additionally, he has developed a "Method and apparatus for tympanic membrane shrinkage," which involves directing energy onto spots of the tympanic membrane to heat the collagen matrix layer and induce shrinkage. This method employs energy in the frequency range of 1.4 to 2.6 microns, aligning with the collagen absorption range.
