Embodiment Construction

[0083] An instrument port includes a handle, an elongated shaft, a bendable shaft, and a steerable tip. The bendable shaft can be controllably bent in one plane using one or more rods on the handle. The proximal end of the bendable shaft is mechanically coupled to the elongated shaft, and the distal end of the bendable shaft is mechanically coupled to the steerable tip. When the bendable shaft is in the unbent state, the bendable shaft extends along the axis of the shaft along which the elongated shaft extends. When the bendable shaft is in the bent state, the bendable shaft bends or flexes relative to the axis of the shaft to direct the steerable tip to a customizable angle or orientation relative to the axis of the shaft. The bendable shaft can be bent without affecting the position, shape, orientation and / or behavior of the elongated shaft. For example, when the bendable shaft 220 transitions from an unbent state to a bent state, the elongated shaft may remain in the defl...

Abstract

The instrument port includes an elongate shaft, a steerable tip, a biasing balloon, and a working tube. An elongate shaft has a proximal end and a distal end and extends along an axis of the shaft, the elongate shaft having a fluid port defined in an outer surface at the distal end of the elongate shaft. A steerable tip is attached to the distal end of the shaft. The biased balloon is attached to an outer surface of the elongate shaft, the biased balloon having an interior volume in fluid communication with the fluid port, the biased balloon having an expanded state in which the biased balloon expands radially asymmetrically with respect to an axis of the shaft, and a contracted state in which the biased balloon expands radially asymmetrically with respect to the axis of the shaft. And a working tube disposed in the elongate shaft, the working tube forming a working channel to receive a medical instrument.
