Abstract
A surgical method for increasing the size of a tissue weld in clamped tissue is disclosed. The method includes providing an end effector for an ultrasonic surgical instrument. The end effector includes an ultrasonic blade having a proximal and a distal end and a clamping mechanism having a clamping surface positioned opposite the ultrasonic blade. The clamping mechanism is adapted to clamp tissue against a side of the ultrasonic blade. A first and a second support surface are positioned laterally on two sides of the ultrasonic blade. Both support surfaces are ultrasonically isolated from the blade and positioned opposite at least a portion of the clamping surface. The method includes actuating the clamping mechanism to clamp tissue between the clamping surface and the ultrasonic blade and between the clamping surface and the first and second tissue support surfaces to define a substantially continuous pressure region. Finally, ultrasonic energy is applied to the ultrasonic blade for the creation of a tissue weld in the substantially continuous pressure region. The tissue weld spreading from tissue clamped between the clamping surface and the ultrasonic blade and into tissue clamped between the clamping surface and the first and second tissue support surfaces.

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.
