Patent number: 11344188Abstract: An actively bendable sheath such as ureteral access sheath (UAS) and a method for delivering a medical instrument (e.g. a ureteroscope) therethrough are disclosed. The sheath's tubular wall includes a deflectable or bendable segment at or adjacent to the distal sheath end. Two pull/control wires are slidably disposed within two separate dedicated channels/lumens and attached to points distally beyond the deflectable segment. The bendable segment may be passively bended by force from a bending medical instrument within it or by the force of a surgeon pulling one of the two pull/control wires.Type: GrantFiled: May 30, 2021Date of Patent: May 31, 2022Assignee: OTU Medical Inc.Inventors: Xibo Wei, Geping Liu

Patent number: 11241150Abstract: The present invention discloses a flexible digital ureteroscope that is at least partially disposable. The ureteroscope comprises a single-use catheter and a handle. The catheter comprises a distal end, a bend portion, and a proximal portion. The distal end has a rigid or semi-rigid shell that houses a set of micro lenses, an image sensor microchip, and a plurality of LED light sources. A working channel extends along the entire catheter and is coupled to a working channel port on the handle to receive various medical devices and irrigation lines during an endoscopic procedure. In addition, the catheter includes one or more steering wires to control the distal end to bend towards a desired direction. The rigid or semi-rigid shell of the distal end is made of a mix of polymer composite material with graphene nano-filler for enhancing thermal dissipation. The handle may be a single-use handle or a reusable handle.Type: GrantFiled: July 13, 2017Date of Patent: February 8, 2022Assignee: OTU Medical Inc., a California CorporationInventors: Geping Liu, Xibo Wei, Xiyi Wei

Patent number: 11129519Abstract: This present invention proposes new methods of designing single-use endoscopes with built-in optical fibers and operating fixtures. As compared to conventional endoscopes, a separate lumen is reserved for integrating a laser fiber along the insertion tube of the proposed endoscope, and an optical fiber placement device (OFPD) is correspondingly added in the endoscope handle for controlling the movement of the laser fiber. By sliding the slider or dialing the wheel of OFPD, a surgeon can conveniently control movement of the laser fiber. By pressing a retractable control stick in the OFPD, the surgeon can either push the laser fiber out from the endoscope's distal-end or pull back the laser fiber, further unlocking or locking the power switch of the laser fiber to avoid mis-operations. All these above operations can be performed by the surgeon's one-hand, including the routine deflections and rotations of the endoscope. Four implementations of the OFPD are introduced in this invention.Type: GrantFiled: January 30, 2018Date of Patent: September 28, 2021Inventors: XiBo Wei, GePing Liu, XiYi Wei

Publication number: 20190328373Abstract: The present invention provides a device that can move inside a biological conduit such as an intestinal tract for sampling the content therein, and a process thereof. The device includes a flexible tube, a proximal handling system connected to a proximal end of the tube; and one or more sampling channels within the tube. Discrete hairs and/or continuous belt in the sampling channels are designed to collect the content within the conduit. The hairs and belt loaded with the sample may be used to establish a chemical, biochemical and microbiological spectrum along the length of the intestinal tract.Type: ApplicationFiled: July 10, 2019Publication date: October 31, 2019Inventors: Xibo Wei, Xiyi Wei

Publication number: 20190192811Abstract: The present invention proposes a method of transforming a traditional, single-use medical tube to a novel one with add-on endoscopic capabilities. A tiny, transparent shell is added at the distal end of the medical tube for containing lighting sources inside, and the lighting source can be any small-size LED, OLED, or ?LED device. Moreover, the tube has one additional lumen for installing power wires of the lighting sources, and another isolated lumen for inserting a flexible endoscope (video/image camera system) to observe targets inside human body. For minimizing outer diameter and cost, this endoscope does not include any built-in lighting source. While in use, the endoscope is first inserted into the medical tube through its specific lumen, and the lighting source at the tip is on. Secondly, the whole medical tube is safely inserted into human body for diagnosis or treatment with the help of endoscopic videos.Type: ApplicationFiled: December 26, 2017Publication date: June 27, 2019Applicant: OTU Medical Inc., a California corporationInventors: XiBo WEI, GePing Liu, XiYi Wei

Patent number: 10045760Abstract: The present invention provides a device that can move inside a biological conduit such as an intestinal tract for sampling the content therein, and a process thereof. While moving along the intestinal tract, the device can continuously collect the content in the intestinal tract. One or more convoy belts having an adsorbent layer are configured to continuously absorb and preserve the collected intestinal content. The belt loaded with the sample may be used to establish a chemical, biochemical and microbiological spectrum along the length of the intestinal tract.Type: GrantFiled: April 13, 2017Date of Patent: August 14, 2018Inventors: Xibo Wei, Sara Shi Wei

Patent number: 10040370Abstract: The present invention provides a container, a transportation system comprising such a container, and a method of using the transportation system. The container includes a battery that provides electricity to a vehicle such as an unmanned aerial vehicle that is carrying and shipping the container. The battery functions as a supplemental power supply to the vehicle and hence improves the endurance of the vehicle, so that heavier cargo can be shipped over longer distance.Type: GrantFiled: September 19, 2016Date of Patent: August 7, 2018Assignee: Ningbo Wise Digital Technology Co., LtdInventors: Xibo Wei, Yuanyuan Li, Jingjing Wei
