Steerable intraluminal medical device

摘要

A steerable intraluminal medical device is described for use in navigating small diameter and curving arteries. The device includes a control handle that adjusts the direction of deflection of the tip throughout a 360° range of motion around the axis on the distal end. An optional locking mechanism is provided to maintain the desired angle of deflection during an intravascular procedure.
