Patent number: 11963807Abstract: A tethered laparoscopic probe is provided, the tethered laparoscopic probe for deployment through a trocar into a cavity of a subject to detect gamma radiation from a radiopharmaceutical administered to the subject. The laparoscopic probe comprises a probe head shaped for insertion through the trocar and configured to be freely moveable within the cavity. The probe head comprises an elongate casing comprising radiation shielding for inhibiting gamma radiation from passing through the probe head, the radiation shielding having a detection aperture for admitting gamma radiation. The probe head further comprises a gamma radiation detector arranged within the casing, the gamma radiation detector configured to detect gamma radiation through the detection aperture of the casing. The probe head further comprises means for, in use, facilitating the localization of a source of radiation from the radiopharmaceutical within the cavity.Type: GrantFiled: August 5, 2020Date of Patent: April 23, 2024Assignee: Lightpoint Surgical Ltd.Inventors: David Tuch, Kunal Vyas, Stewart Forbes, Gavin Ryan, Phil Marsden

Publication number: 20210161549Abstract: A tethered laparoscopic probe for deployment through a trocar into a cavity of a subject and manipulatable by fenestrated laparoscopic graspers includes opposing fenestrated jaws. The tethered laparoscopic probe also includes a probe head shaped for insertion through the trocar and including an elongated casing, a sensor arranged within the casing and defining a sensing direction of the probe head, and a grip for secure grasping by the fenestrated laparoscopic graspers. The grip has protrusions for mating with the fenestrated jaws. The tethered laparoscopic probe further includes a tether coupled to the probe head. The protrusions are positioned and shaped to enable the grip to be grasped securely by the fenestrated laparoscopic graspers at a first angle relative to the sensing direction of the probe head and at a second angle relative to the sensing direction of the probe head, the second angle being different from the first angle.Type: ApplicationFiled: January 19, 2021Publication date: June 3, 2021Applicant: LIGHTPOINT MEDICAL, LTDInventors: Kunal Vyas, Gavin Ryan, David Tuch, Stewart Forbes, Francesca Oldfield

Patent number: 6247918Abstract: In an apparatus for monitoring a hydrocarbon flame, a plurality of radiation sensors detect electromagnetic radiation emitted by the flame. Each of the sensors is provided with a narrow band filter so that the corresponding sensor is responsive only to a narrow range of wavelengths. In this manner, one of the sensors is made responsive to emissions due to transient species in the flame and one of the sensors is made responsive to emissions from a non-transient species in the combustion region. The signals from the radiation sensors are converted to digital and applied to a central processing unit where they are compared to produce an output indicative of the combustion conditions in the flame. An output unit responds to the output signal from the central processing unit to adjust the air fuel ratio in the flame to a desired level, such as just above stoichiometric.Type: GrantFiled: November 12, 1999Date of Patent: June 19, 2001Assignee: Forney CorporationInventors: Stewart Forbes, Brian Powell
