Abstract
An embodiment of the present invention provides for an elongated medical device with a hypotube backbone running through the device, and a spiral lumen spiraled around the backbone along the length of the backbone. The backbone may be formed from a nitinol alloy for increased bendability without compromising axial stiffness. The device may also incorporate a jacket around the hypotube and spiral lumen formed using either melting, molding, bonding, or casting. The spiral lumen may be configured to accommodate a variety of uses, including actuation members (e.g., pull wires), tools, and means for aspiration, irrigation, image capture, and illumination. Additionally, the present invention provides a method for constructing an elongated medical device with a hypotube backbone running through the device, and a spiral lumen spiraled around the backbone along the length of the backbone.
