Abstract
A catheter navigation apparatus includes a catheter system for percutaneous insertion into an internal organ cavity. The catheter system includes a treatment catheter and a navigation catheter; the navigation catheter includes a deployable framework at its distal end; the treatment catheter includes at least one conduit extending from its proximal to its distal end; the conduit having its distal end engaged with the framework; the navigation catheter includes a flexible link interconnecting the framework with a control mechanism at the proximal end of the navigation catheter for driving the link to deploy and retract the framework to guide the distal tip of the treatment catheter to target one or more selected positions on the inner wall of the organ cavity.
