<p>The present invention provides an apparatus for, and a method of, accurate rotational positioning of endoscopic instruments. Accurate positioning of the instruments is accomplished through the inclusion of a steering ability within the device. After the endoscopic instrument is properly positioned the present invention may use rapid exchange technology, soft locks, and mechanical locks to maintain the position of the endoscopic instrument. Rapid exchange technology is used to minimize displacement forces present on the guidewire or catheters. Soft locks and mechanical locks resist movements caused by displacement forces. The device consists of a catheter rotationally connected to a handle with means to lock the rotational connection.</p> |
