Patents by Inventor Miguel LLERA

Miguel LLERA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230194774
    Abstract: Disclosed is an optical waveguide, for transmitting a guided optical light beam having a wavelength greater than 180 nm. The waveguide includes a core layer for guiding light made of a first material having a first index of refraction, and a cladding layer made of a thermoplastic elastomer. Also disclosed are: a medical device and also to a waveguide sensor including the optical waveguide of the invention; a method of fabrication of the optical waveguide. The method includes a step of providing a thermoplastic elastomer preform having a central longitudinal aperture for introducing a liquid polymer, before or after reducing and elongating the preform to a predetermined length and lateral dimension. The method includes a polymerizing step of the core of the formed optical waveguide; and use of the optical waveguide in association with a surgical instrument.

  • Publication number: 20230194773
    Abstract: Disclosed is an optical waveguide, for transmitting a guided optical light beam having a wavelength >180 nm, including a core for guiding light made of a first material having a first index of refraction, and a cladding including a thermoplastic elastomer, the innermost layer of the cladding having a refractive index smaller than the refractive index of the outermost layer of the core. Also disclosed is a medical device and waveguide sensors including the optical waveguide, as well as a method of fabrication of the optical waveguide. The method is based on the realisation of a full thermoplastic elastomer preform or a preform having a central aperture. Before or after elongating the preform to a predetermined length and a predetermined lateral dimension, the core of the preform is filled and hardened so as to provide such optical waveguide. Also described is a 3D printing method to realize the preform.
