Abstract
A bi-directional catheter comprises an elongated body, a tip section and a control handle. The body has at least one lumen extending therethrough. The tip section is mounted at the distal end of the catheter body and has at least two diametrically-opposed off-axis lumens. The first off-axis lumen is smaller than the second off-axis lumen. The control handle is mounted at the proximal end of the catheter body and comprises at least two moveable members longitudinally movable between first and second positions. The catheter further comprises first and second puller wires. The proximal end of each puller wire is connected to an associated movable member of the control handle. Each puller wire extends from the control handle through a lumen of the catheter body. The first puller wire extends into the first lumen in the tip section, and the second puller wire extends into the second lumen in the tip section. The distal end of each puller wire is anchored to the tip section. An electrode is mounted on the tip section, and a lead wire is electrically connected to the electrode. The lead wire extends through the second lumen in the tip section, through a lumen in the catheter body and into the control handle. Proximal movement of a movable member relative to the catheter body results in proximal movement of the puller wire associated with that movable member relative to the catheter body, and thus deflection of the tip section in the direction of the lumen in which that puller wire extends.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
