    摘要: 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.

    摘要: A video assisted thoracoscopic transmyocardial revascularization (TMR) surgical method includes making at least two spaced incision ports between the ribs of a patient proximate the patient's heart; inserting through one of the ports a thoracoscopic TMR handpiece assembly for creating a channel through the heart wall; inserting through the other incision port a thoracoscope connected to a video display system; viewing the heart of the patient through the video display system and positioning the handpiece assembly relative to the heart; and actuating the handpiece assembly to create a channel through the wall of the patient's heart.
