  • Publication number: 20200206458
    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.

  • Patent number: 10624532
    Abstract: In some embodiments, an insertion device for a robotic surgery apparatus can include a first portion with a plurality of instrument channels configured to removably house a plurality of surgical instruments and first and second camera channels positioned in an interior of the first portion and extending along substantially the entire length of the first portion. The first camera channel can removably house a primary camera tube, and the second camera channel can include a secondary camera. The device can include a second portion with an insertion channel terminating at a first end with a first opening permitting the primary camera tube to pass through and terminating at a second end opposite the first end with a second opening aligned with the first camera channel of the first portion. The insertion channel can permit the primary camera tube to pass through the insertion channel and enter the first camera channel.

  • Publication number: 20200113417
    Abstract: In some embodiments, a visualization device for a robotic surgery apparatus can include a housing configured to be removably attached to a mounting interface of the apparatus and be positioned adjacent an insertion device of the apparatus. The housing can include first and second openings positioned on an exterior of the housing. The housing can include a substantially flexible camera tube with a first end attached to the housing and a second end including at least one camera. The second end can be inserted through the first opening in the housing, pass through interior of the housing, and exit the housing through the second opening in the housing. The second end can extend away from the housing toward a region of interest outside the housing or retract away from the region of interest and back toward the housing. The camera tube can form a loop around a portion of the housing.

  • Publication number: 20190350589
    Abstract: The present disclosure describes an occlusion device and methods of delivering the occlusion device. The occlusion device can include an expandable structure configured to move between an unexpanded configuration and an expanded configuration. The expandable structure can be configured to have an expansion ratio of at least about 5:1. Further, the occlusion device can be configured to prevent substantially all fluid from flowing past the occlusion device when the occlusion device is in the expanded configuration in the vessel.
