Publication number: 20200309649Abstract: Disclosed herein are receptacles for use in staining and/or rinsing samples. In some embodiments, a receptacle includes a container and a container top. A container may be sized and shaped to contain fluid and a sample submerged in the fluid. The fluid may be, for example, staining agent solution or rinsing solution. In some embodiments, a kit is provided that includes a first receptacle that includes a container partially filled with staining agent solution and a second receptacle that includes a container partially filled with rinsing solution. In some embodiments, a receptacle includes a container and a basket that is positionable in the container. A basket may include a permeable sample holding element that is permeable to fluid in a container so that samples can be sufficiently stained or rinsed. In some embodiments, a receptacle is a single-dose receptacle that is used intraoperatively (e.g., in an operating room).Type: ApplicationFiled: March 2, 2020Publication date: October 1, 2020Inventors: Etienne Shaffer, Aurèle Timothée Horisberger, Frédéric Schmitt, Bastien Rachet

Publication number: 20200284703Abstract: Disclosed herein are staining agent solutions for use in fluorescence microscopy. One example of fluorescence microscopy in which the staining agent solutions are useful is intraoperative confocal microscopy. Intraoperative confocal microscopy can be used, for example, to assess margins of resected cancerous tissue. Example staining agent solutions include acridine orange, where the pH of the solution is from 6 to 8, for example from 6.8 to 7.4. The solution may include a phosphate-buffered saline (PBS). The solution may be isotonic. The solution may comprise one or more of potassium dihydrogen phosphate, disodium hydrogen phosphate, and sodium chloride. In some embodiments, the staining agent solution does not comprise acetic acid (e.g., an acetate buffer). Staining agent solutions disclosed herein may reduce adverse impacts to tissue resulting from staining. Staining agent solutions disclosed herein may preserve normal appearance of tissue.Type: ApplicationFiled: March 2, 2020Publication date: September 10, 2020Inventors: Etienne Shaffer, Aurèle Timothée Horisberger, Frédéric Schmitt, Bastien Rachet

Publication number: 20200257098Abstract: Disclosed herein are systems for imaging of samples, for example, using an array of micro optical elements and methods of their use. In some embodiments, an optical chip comprising an array of micro optical elements moves relative to an imaging window and a detector in order to scan over a sample to produce an image. A focal plane can reside within a sample or on its surface during imaging. In some embodiments, detecting optics a reused to detect back-emitted light collected by an array of micro optical elements that is generated by an illumination beam impinging on a sample. In some embodiments, an imaging system has a large field of view and a large optical chip such that an entire surface of a sample can be imaged quickly. In some embodiments, a sample is accessible by a user during imaging due to the sample being exposed.Type: ApplicationFiled: April 29, 2020Publication date: August 13, 2020Inventors: Etienne Shaffer, Bastien Rachet, Aurèle Timothée Horisberger, Jonathan Abel Pirolet, Diego Joss, Andrey Naumenko, Frédéric Schmitt

Publication number: 20190129158Abstract: Disclosed herein are sample dishes for use with microscopes that are simple to mount on a microscope and facilitate easy manipulation of tissue samples disposed thereon during imaging as well as methods of their use. A sample dish comprises an optical interface and, optionally, a support member that holds the optical interface. The optical interface of a sample dish is suitably transparent and planar such that a focal plane of a microscope can reside uniformly at or within a surface of a sample during imaging. In certain embodiments, a support member comprises a dish for holding excess fluid. In certain embodiments, a sample dish comprises separation ribs. In certain embodiments, a sample dish comprises one or more manipulation members (e.g., tabs). In certain embodiments, a sample dish is used with an imaging artifact reducing fluid.Type: ApplicationFiled: September 28, 2018Publication date: May 2, 2019Inventors: Etienne Shaffer, Jonathan Abel Pirolet, Frédéric Schmitt, Bastien Rachet, Diego Joss

Publication number: 20180348142Abstract: The disclosed technology brings histopathology into the operating theatre, to enable real-time intra-operative digital pathology. The disclosed technology utilizes confocal imaging devices image, in the operating theatre, “optical slices” of fresh tissue—without the need to physically slice and otherwise process the resected tissue as required by frozen section analysis (FSA). The disclosed technology, in certain embodiments, includes a simple, operating-table-side digital histology scanner, with the capability of rapidly scanning all outer margins of a tissue sample (e.g., resection lump, removed tissue mass). Using point-scanning microscopy technology, the disclosed technology, in certain embodiments, precisely scans a thin “optical section” of the resected tissue, and sends the digital image to a pathologist rather than the real tissue, thereby providing the pathologist with the opportunity to analyze the tissue intra-operatively.Type: ApplicationFiled: August 3, 2018Publication date: December 6, 2018Inventors: Bastien Rachet, Davor Kosanic, Etienne Shaffer
