  • Patent number: 10245039
    Abstract: Methods and apparatuses relate to an implantable apparatu0s that may be used to apply tensile force(s) to one or more tissue regions (e.g., proximal and distal esophagus portions, bowel, other conduits) within the body. Such tensile force(s) may cause stretch and/or growth of the tissue region(s). In various embodiments, support members (e.g., suture rings) may be attached to respective tissue regions. The support members may accommodate attachment of a number of sutures along the tissue region. Upon suitable attachment of the support member(s) to the tissue region(s), the actuator may be coupled to the support member(s). The actuator may then be controlled so as to cause relative movement between the support members toward or away from one another. Such movement may result in the application of appropriate tensile force(s) to the tissue region(s).

  • Patent number: 9675781
    Abstract: Embodiments of the present invention provide a continuum manipulator that can be used, for example, as a steerable catheter tip. The manipulator of the embodiments comprises a plurality of segments arranged in a stack, which is then able to bend in a range of directions away from the long axis of the stack. In one embodiment the segments include a helical portion which winds in the direction of the long axis of the stack, and can thus bend away from the long axis in any direction. In some embodiments a carbon fiber rod is included as a backbone for the stack, to minimize hysteresis and improve repeatability of bending. In addition, in embodiments of the invention tendon control channels are provided formed within the segments, through which tendon control wires extend to apply compression and/or bending forces to the stack.

  • Publication number: 20160367120
    Abstract: A device for performing surgical procedures, such as intracardiac procedures or neurosurgical procedures, includes a solid optical window formed of a transparent, compliant material, wherein the solid optical window includes a proximal side and a distal side, wherein a distal face of the solid optical window is configured to approach tissue during a surgical procedure; an imaging system embedded into the solid optical window and positioned to obtain an image through at least a portion of the distal face of the solid optical window; and a tool channel formed through the solid optical window from the proximal side to the distal side of the solid optical window, wherein the tool channel is configured to receive a tool for performing the surgical procedure.

In one embodiment the segments include a helical portion which winds in the direction of the long axis of the stack, and can thus bend away from the long axis in any direction. In another embodiment the segments include a backbone portion with cantilevered rings extending from the backbone portion, separated by bending gaps which allow the segment to bend in a range of directions away from the backbone portion so that the bending gap between the rings closes. In some embodiments a carbon fibre rod is included as a backbone for the stack, to minimise hysteresis and improve repeatability of bending.
