Patent number: 11517199Abstract: Embodiments for crossing an occlusion by controlling a guide with the aid of optical coherence tomography (OCT) data are described. Embodiments include transmitting one or more beams of radiation via one or more waveguides on a flexible substrate within a guide wire. One or more beams of scattered or reflected radiation may be received from a sample via one or more waveguides. Depth-resolved optical data of the sample may be generated based on the received beams of scattered or reflected radiation. The depth-resolved data may be used for determining at least one of a distance between the guide wire and a wall of the artery and a distance between the guide wire and an occlusion within the artery. A position of the guide wire within the artery may then be controlled based on the determined distance or distances.Type: GrantFiled: February 15, 2019Date of Patent: December 6, 2022Assignee: Medlumics S.L.Inventors: Eduardo Margallo Balbás, Alejandro Barriga Rivera, José Luis Rubio Guivernau, Santiago Jiménez Valero, Juan Lloret Soler

Publication number: 20190232052Abstract: The present invention relates to a method and apparatus for facilitating artificial vision using retinal electrical neuro-stimulation. Retinal ganglion cells are stimulated at two different sites in order to elicit better visual percepts. Primary stimulation is implemented at first site on the retina. Secondary stimulation is applied in the vicinity of the optic disc or optic nerve. The secondary stimulation modulates the signals elicited by the primary stimulation.Type: ApplicationFiled: June 23, 2017Publication date: August 1, 2019Inventors: Alejandro Barriga-Rivera, Tianruo Guo, Gregg Jørgen Suaning, John W. Morley, Nigel Hamilton Lovell

Publication number: 20150133778Abstract: Systems and methods for use of the imaging system are presented. In an embodiment, the imaging system includes a first optical path, a second optical path, a plurality of optical elements, a detector, and a processor. The first optical path guides a first beam of radiation associated with epiluminescence while the second optical path guides a second beam of radiation associated with optical coherence tomography. The plurality of optical elements transmit the first and second beams of radiation onto a sample. The detector generates optical data associated with the first and second beams of radiation returning from the sample. The optical data associated with the first and second beams of radiation correspond to substantially non-coplanar regions of the sample. The processor correlates the optical data of the first beam with the optical data of the second beam and generates an image of the sample.Type: ApplicationFiled: October 31, 2014Publication date: May 14, 2015Applicant: Medlumics S.L.Inventors: Alejandro Barriga Rivera, José Luis Rubio Guivernau, Eduardo Margallo Balbás
