A work tip for an ultrasonic surgical device has a distal end incorporating an upward projection that extends from about 10 to about 50% of the inner diameter of the hollow tip. An angled front face of the tip leads to an upper edge of the projection, which, under ultrasonic vibration assists in the break-up and emulsification of surgically displaced material, which is removed by vacuum through a passage in the work tip.
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.
