Patent number: 12023005Abstract: An illumination system for illuminating a lumen within a body of a patient comprising a tube having a proximal end and an opposed distal end and an internal chamber, the tube being configured for placement within a lumen of the body. The system also includes an illumination subsystem including an optical fiber that is sized and configured to seat within the internal chamber of the tube and a light source for generating light that is emitted by the fiber optic cable. The optical fiber, when mounted within the tube and when the light source generates light, emits light at the distal end of the tube so as to transilluminate the lumen and surrounding tissue so as to be able to locate the distal end of the tube within the lumen of the patient.Type: GrantFiled: December 31, 2019Date of Patent: July 2, 2024Assignees: Fraen Corporation, Neuroceuticals Inc., Acera LLCInventors: Shinya Miike, Thomas V.

Patent number: 11467393Abstract: An elliptical lens comprises a lens body having a proximal section and a distal section. The proximal section has at least one input surface for receiving light from a light source and the distal section has at least one output surface through which light exits the lens body. The proximal section further comprises a substantially elliptical peripheral surface receiving at least a portion of the light entering the lens body via the at least one input surface and directing at least some of the received light via total internal reflection to the distal section such that at least a portion of the light directed to the distal section exits the lens body through said at least one output surface. Optical assemblies having said elliptical lens may be embedded in medical devices such as endoscopes to provide efficient illumination.Type: GrantFiled: October 28, 2016Date of Patent: October 11, 2022Assignee: Acera, LLCInventors: Carlton Jones, Rachel Taranta, Thomas V.

Publication number: 20210402320Abstract: A continuous vacuum fractionation system for separation of one or more of the plurality of components present in a raw cannabis extract into at least an overhead fraction, a bottoms fraction, and a side stream fraction, wherein the raw cannabis extract may be prepared by any of a variety of extraction techniques. The system includes an extract supply assembly having a primary feed pump, and one or more continuous fractionation units each including a modular fractionation column. Each column has a re-boiler, a close-coupled overhead condenser, and at least one modular fractionation stage, and further, the columns are operable in either series or parallel configurations. The close-coupled overhead condenser has an oversized impingement plate overlying a condenser inlet to minimize non-vapor components from entering and contacting the condenser. A vacuum assembly is provided to maintain at least the modular fractionation columns under a predetermined vacuum during operation.Type: ApplicationFiled: August 5, 2020Publication date: December 30, 2021Inventor: Robert Carlton Jones
