Abstract
A surgical tool for inserting a spile or plug into the punctal opening of a meatus such as a lacrimo-nasal canaliculus comprises an oblong, hollowed member shaped and dimensioned to be conveniently manipulated with one hand and having at one of its end a punctal opening and meatus-dilating shaft and, at the opposite end, a plug inserter. The dilating shaft has a cross-diameter substantially equal to the cross-diameter of the plug and is terminated by a conical spike. The inserter comprises a tip extending axially from the member and having, at its distal end, a cup whose internal geometry is commensurate with a cap at the proximal end of the plug. A penetration-resisting bearing surface is provided by the cup rim. The plug can be allowed to retract within the cup under the force of insertion. A steel wire running through the inserter has its distal end inserted into the cap of the plug. The wire can be axially withdrawn by unidirectionally pressing a button in order to release the plug after insertion into the meatus.

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.
