  • Publication number: 20190255292
    Abstract: A steerable intravascular catheter includes a handle assembly having opposed proximal and distal end portions and defining a longitudinal axis therebetween. An elongated sheath extends from the distal end portion of the handle assembly, has opposed proximal and distal end portions, and includes a tubular body wall forming a central lumen for accommodating the introduction of a device and a fluid lumen radially outward from and parallel to the central lumen. The distal end portion of the elongated sheath is deflectable relative to the proximal end portion of the elongated sheath. A rotatable actuation assembly is associated with the handle assembly for controlling deflection of the distal end portion of the elongated sheath. An inflatable occlusion balloon is positioned on an outer surface of the distal end portion of the elongated sheath. The fluid lumen of the elongated sheath is in fluid communication with an interior of the balloon.

  • Patent number: 9572957
    Abstract: A surgical apparatus includes an elongated handle assembly having opposed proximal and distal end portions and an interior cavity. An elongated sheath extends from the proximal end of the handle assembly, through the interior cavity of the handle assembly and out from the distal end portion of the handle assembly. The sheath includes an interior lumen extending therethrough and a distal end portion of the sheath is deflectable. The surgical apparatus includes a steering mechanism operatively associated with the handle assembly for controlling deflection of the deflectable distal end portion of the sheath. The steering mechanism includes a pull wire retraction assembly configured to selectively retract a pull wire to deflect the distal end portion of the sheath and a telescoping tube system for straightly guiding the pull wire as the pull wire retraction assembly moves within the interior cavity of the handle assembly.
