Publication number: 20240090922Abstract: A rotatable chip-on-tip endoscope is configured to be operated with a single hand, with the palm holding the body of the device and one or two fingers operating a distal rotatable end of the handle that carries the needle. The needle is small in diameter, preferably less than 2.5 mm at its largest end. As the tip is rotated to view more widely in a patient's joint, for example, video processing electronics correct rotational orientation in real time to present a consistent moving image on a monitor.Type: ApplicationFiled: May 5, 2022Publication date: March 21, 2024Inventors: TheofiIos Kotseroglou, Stephanos Papademetriou, Stephen A.

Publication number: 20240075228Abstract: A laryngeal mask airway device that establishes pulmonary breathing of a patient and receives a endotracheal tube includes an airway tube with a distal end mask, the mask having a peripheral cuff to form a seal around the patient's laryngeal inlet. An endoscope channel is formed separately from the airway tube so as to receive an endoscope capable of illuminating and viewing the laryngeal anatomy. The endoscope channel may be closed by a transparent viewing window at a distal end. In an embodiment the endoscope channel has a mechanical asymmetry to ensure proper insertion of the visualizaton stylet. The airway device may include an additional channel for monitoring pressure in the laryngeal region. A visualization stylet to be used with the airway device is preferably connected wirelessly to display equipment. The airway device can also include markings to be imaged by the visualization stylet during insertion, for correct placement and to assess dimensions of a patient's anatomical features.Type: ApplicationFiled: November 18, 2022Publication date: March 7, 2024Inventor: Stephanos Papademetriou

Publication number: 20240016376Abstract: A clip for use in carpal tunnel surgery and similar surgeries has two separate clip sections, each with a proximal end that snaps together with the opposing proximal end of the other section, to make an assembled clip with a space between the sections except at proximal ends. At least one of the clip sections can be configured as a dilator, with a tapered distal end and without sharp edges. The two clip sections form endoscope and live channels to receive a viewing endoscope and a knife, inserted through the proximal end of the assembled clip device. Illumination is provided, either within the clip or from the scope of another inserted device, to enable viewing through the endoscope during a procedure. An embodiment of the clip device is formed with a rotation hub, such that the two clip sections can be swung apart or used together in a surgical procedure.Type: ApplicationFiled: July 18, 2022Publication date: January 18, 2024Inventors: Theofilos Kotseroglou, Stephanos Papademetriou, Ulrich R.

Patent number: 11602374Abstract: A Veress needle is modified to receive a forward-looking miniature videoscope through the lumen of an insufflation tube of the Veress needle. The modified instrument enables direct viewing of progress of the instrument through tissue to the peritoneal cavity of a patient, for proper location of the needle and insufflation of the cavity via the needle. The videoscope has an elongated shaft of smaller diameter than the lumen of the insufflation tube for passage of insufflation gas with the scope in place. In another embodiment a needle is fitted with a miniature videoscope to provide the same function, with the needle's lumen serving as an insufflation tube.Type: GrantFiled: March 4, 2022Date of Patent: March 14, 2023Assignee: Enable, Inc.Inventor: Stephanos Papademetriou

Patent number: 6339470Abstract: An apparatus, including a light detecting means, determines the actual position of an optical fiber array having one or more, but fewer than all, short fibers by detecting light transmitted through the short fiber(s) as a laser beam is horizontally and/or vertically scanned across the proximal fiber end(s). The fiber array is attached to an alignment block that facilitates delivery of the array to an accurate positioning means comprising two substantially parallel dowels.Type: GrantFiled: April 26, 1999Date of Patent: January 15, 2002Assignee: EndoVasix, Inc.Inventors: Stephanos Papademetriou, Victor C.

Patent number: 5875275Abstract: A fiber optic radiation transmission system is provided in which an optical fiber and a radiation source are connected to establish optical communication therebetween. Additionally, a connecting system is provided for connecting an optical fiber and a radiation source such that optical communication is established therebetween. The systems include a connector which carries the optical fiber therein. The connector is extendable within the system toward the radiation source to bring the optical fiber into optical communication with the radiation source. More particularly, the systems are configured in such a way that when the connector is extended sufficiently within the system, it seats the optical fiber relative to the radiation source under bias, thereby establishing a reliable optical connection. Once the optical connection is thus established, the connector engages a connection port associated with the radiation source to secure the system in a fully connected configuration appropriate for use.Type: GrantFiled: November 26, 1997Date of Patent: February 23, 1999Assignee: Indigo Medical, Inc.Inventors: William James Evans, Thomas Henning, Kelly Cox, Victor C. Esch, Yefim Gelfond, Stephanos Papademetriou, Daren L. Stewart
