Abstract
The tubal ligation instrument of the present invention includes structure for ligating anatomical tubes within the human or animal body, and structure for anesthetizing the anatomical tubes being ligated. An example of an anatomical tube is a Fallopian tube. The instrument further includes a structure for grasping the anatomical element. The grasping structure extends through a channel in the instrument housing. Usually the grasping structure is a rod having forceps tongs at one end with a flat surface formed on a side portion of the rod. Consequently, the rod does not occupy the entire housing leaving a channel between the rod and the housing. On an outside surface of the instrument housing is an anesthesia receiving means, typically a stopcock. A channel through the stopcock, through which anesthesia may flow, is capable of communicating with the channel between the rod and the housing. The application of anesthesia to an anatomical element is accomplished by introducing the anesthesia through the stopcock and into the unoccupied channel of the housing. Thus, a surgeon directing the end of the instrument to an anatomical element can apply an anesthetic agent to the anatomical element intraabdominally, by the method of the present invention.

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.
