  • Patent number: 10821265
    Abstract: The presence of the pull wire ring in the distal end portion leads to limited functionality of the distal end of a steerable medical device. A steerable medical device (1) includes a pull wire ring (100a-e) for imparting a bending movement on the steerable medical device. By providing the pull wire ring (100a-e) with an eccentric recess (105a-f) which defines a passage between a first end face (101) and a second end face (105) of the ring, it becomes possible to guide ancillary elements such as electrical lines, data cables and fiber optics past the pull wire ring (100a-e) further towards the distal end of the steerable medical device. By this measure, functionality of the distal end of the medical device is enhanced without obstructing a main lumen of the device.

  • Publication number: 20200196836
    Abstract: An invasive medical device (10) is disclosed comprising an elongate device portion (20) attached to a handle (30), the elongate device portion including a flexible tip (21) at a distal end of the elongate device portion and a plurality of pull wires (23) attached to said flexible tip; and a plurality of electrically conductive shape memory elements (33) entirely contained with in said handle, each of the shape memory elements coupled to and extending in a length direction between one of said pull wires and a current source connection (61) arranged to provide an electrical current to said electrically conductive shape memory element, each of the electrically conductive shape memory elements having a negative coefficient of expansion in said length direction. The invasive medical device (10) preferably comprises a cooling arrangement (70, 80) for the plurality of electrically conductive shape memory elements to reduce the relaxation times of the shape memory elements.

  • Patent number: 10620386
    Abstract: An optical connector system for reversible optical connection between two optical fibers (102, 104) with their end parts inside respective ferrules. A receptacle arrangement has a receiving body (105) for receiving at least one of the ferrules (103). An optical element (106) of the receptacle arrangement serves to provide optical connection between the two optical fibers in a connected state of the optical connector system, and at the same time, the optical element (106) serves as a sterility barrier between the two optical fibers. The optical element (106) can be an optical waveguide, e.g. a piece of optical fiber similar to the two optical fibers (102, 104), and arranged within the receiving body (105). Alternatively, the optical element may be a thin flexible membrane (207, 307) which is optically transparent.

  • Patent number: 10603060
    Abstract: Attachment assemblies for oral hygiene devices and, in particular, attachment assemblies having improved designs to more effectively clean an individual's tongue or other inter-oral surface are described herein. These improved attachment assembly correspond, amongst other aspects, to improved fluid chamber configurations, improved fluid channel configurations, improved fluid exit hole configurations, improved air inlet hole configuration, and air channel features. Furthermore, these improvements to attachment assemblies are capable of being implemented separately from, or in combination with, one another.

  • Patent number: 10561467
    Abstract: The invention relates to an interventional apparatus comprising an interventional device with a handle (6). The handle comprises a) a first guide (20, 51) guiding an optical fiber, which is also guided within the interventional device, from a first proximal opening (14) of the handle to a distal portion (21) of the handle, wherein the first guide only has radii of curvature being larger than 10 mm, and b) a second guide (22) for guiding an elongated interventional instrument from a second proximal opening (13) of the handle to the distal portion of the handle. Since the first guide is relatively straight, the optical fiber is substantially not bent or only slightly bent and the likelihood that the interventional instrument and the optical fiber press against each other can be significantly reduced. This allows for an improved accuracy of determining the position of the interventional device by optical shape sensing.

  • Publication number: 20190358009
    Abstract: The invention relates to an oral care device for teeth whitening or other purpose. The device is designed to provide a uniform light intensity distribution at the teeth. This is achieved by use of a light guide which at some surface parts is separated from surrounding parts of the mouthpiece of the oral care device by air-filled separation portions. The light guide mixes the injected light to improve the uniformity of the light intensity. In 5 order to couple light out from the light guide, the mouthpiece comprises an out-coupling structure located opposite to the buccal side of the teeth. The out-coupling structure may be shaped, e.g. by changing the area or density of parts of the out-coupling structure depending on the distance to a location of the light guide where light is injected.

  • Publication number: 20190099082
    Abstract: A fiber assembly (60) for capnography or oxygraphy employing an housing (61), a collimator (64), a retroreflector (67) and a single mode optical fiber (63). Housing (61) including a respiratory gas detection chamber (62). Collimator (64) is rigidly disposed within or detachably attached to housing (61), and retroreflector (67) is rigidly disposed within or detachably attached to housing (61). Collimator (64) and retroreflector (67) are optically aligned within housing (61) across respiratory gas detection chamber (62). Optical fiber (63) is optically aligned with collimator (64) within or external to the housing (61). In operation, optical fiber (63) emits a gas sensing light beam through collimator (64) across respiratory gas detection chamber (62) to retroreflector (67), and optical fiber (63) receives a gas detection light beam reflected from retroreflector (67) across respiratory gas detection chamber (62) through collimator (64) to optical fiber (63).

  • Patent number: 9918814
    Abstract: An apparatus (100, 100?) is configured such that passage of a fluid (30) through an open port of a distal tip (112, 112?) enables detection of a substance (116) that may be present on a surface (31, 33), e.g., a surface of a tooth, based on measurement of a signal correlating to a substance at least partially obstructing the passage of fluid (30) through the open port. The apparatus (100, 100?) includes a proximal pump portion (124) and at least one distal probe portion (110) configured to be immersed in another fluid (11), e.g., water in toothpaste foam. A corresponding system (3000) includes one or two such apparatuses (3100, 3200). A method of detecting the presence of a substance on a surface includes probing an interaction zone (17) for at least partial obstruction of flow of the second fluid medium (30) through a distal probe tip.
