Steering tool

Abstract

A steering tool including an internal tube disposed inside an external tube, the internal and external tubes being arranged for longitudinal axial movement relative to one another, wherein a distal end of the internal tube is fixedly joined to a distal end of the external tube, and at least one of the internal and external tubes is slotted near the distal end thereof, and wherein the longitudinal axial movement causes bending of the distal ends of the tubes.

Description

technical field [0001] The present invention generally relates to a guide tool for guiding a medical device through a body cavity. Background technique [0002] As is known in the art, many medical procedures require the introduction of medical devices through blood vessels or other body lumens of a patient. One of the most common methods used involves passing a guide wire through a body lumen to a desired location. Medical devices such as catheters, valves, stents, etc. are positioned by sliding over a guide wire to a desired position. [0003] The lumen through which the guidewire passes can have various bends and branches. Sometimes, in order for a medical device to navigate bends and branches, not only does the guide wire need to be flexible, but the medical device also needs to be flexible. However, delivery system curvature is not always desired. Another problem is the device distal tip, which typically needs to be more bendable and more steerable than the rest of ...

Problems solved by technology

Another issue is the device distal tip, which typically needs to be more bendable and steerable than the rest of the device, and the device must be constructed to allow torque to be applied to the tip
