Abstract
In one embodiment, a steerable guide catheter includes a handle and an elongated shaft extending outwardly away from and being coupled to the handle. The shaft has a distal end opposite the handle. The shaft further has a first preformed curved section at the distal end and a second preformed curved section that is located proximal to the first preformed curved section. The two preformed curved sections can be fabricated as part of a molding process whereby the two preformed curved sections are effectively “baked in” the catheter shaft. The guide catheter also has a steering mechanism for controllably steering at least the first preformed curved section at the distal end. The steering mechanism is coupled between the handle and elongated shaft and being configured such that actuation of the steering mechanism causes the first preformed curved section to be bent in at least two planes.
