Abstract
A medical device for surgical procedures is provided which includes an instrument having a working end defined by a portion of the instrument that can be visualized in a surgical field during a micro-invasive or minimally invasive surgical procedure. The working end includes a tissue manipulating element and a non-reflective outer surface, which covers the working end in its entirety so that the outer surface is free from glare points. The outer surface of the working end is preferably electrochemically etched to form a darkened metal oxide composition surface. The invention also includes micro-invasive surgical assemblies, which include a light source for illuminating the surgical field and visualization means as well as an instrument with a non-reflective working end. Processes for providing a surgical article with a non-reflective surface are also provided. The processes include placing an electrode adjacent the working end of the article and maintaining a gap between the article and the electrode. Electrolyte is supplied to the gap while passing an electric current between the article and electrode to provide a substantially uniform non-reflective surface to the entire working end of the article.

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.
