  • Patent number: 12178391
    Abstract: Systems and methods are disclosed for an endoscope for use in a surgical procedure, e.g., a pediatric trans-nasal endoscopy procedure. The endoscope may include a handle for gripping by a user, and a shaft extending from the handle. The shaft may have a working channel extending longitudinally therethrough and a distal region configured to be inserted into a patient. The distal region of the shaft may include a printed circuit board with a perpendicular portion having an illumination source mounted thereon so as to face distally. The printed circuit board may also have an imaging device mounted thereon, and the imaging device and the illumination source may be located at the same longitudinal position of the endoscope shaft, e.g., flush-mounted. The endoscope may also include, on the handle, an electronic control module having first and second buttons that are mapped to a menu of functions, e.g., white balancing and/or image capture functions, in an external video control unit.

  • Patent number: 11197977
    Abstract: A catheter has a jacket (10, 11, 5) defining a lumen and a helical support (6). The catheter has a proximal portion (1) and a distal portion (3), the distal portion having for at least some of its length a corrugated outer surface. A transition portion has a flexural stiffness which is less than that of the distal portion and more than that of the proximal portion. The transition portion provides an optimum transition in flexural stiffness by way of features of the jacket including geometry of jacket corrugations (15), or overlapping tubular layers (1073, 1074). The distal end of the distal portion may have an extension of liner material folded over (1072, 1082) to provide a particularly soft tip. In other examples the liner is terminated (763) before the distal tip. The catheter is particularly suited to an aspiration device (1350) with a flow restrictor (1353) and the distal portion distal of the flow restrictor.
