Abstract
A method of and structure for separating tissue. The method comprises the step of directing a fluid medium under pressure from a tissue separator including a floating tip at the tissue while floating the tip of the separator on the fluid medium. The tissue may be living tissue and in accordance with the method of the invention may be separated along natural cleavage planes. The fluid medium may be a gas or liquid and may be regulated in pressure and formed in pulses. It may be passed around and/or through the floating tip. The tissue to be separated may also be nudged by the floating tip. The fluid medium may be treated water from a municipal water supply or separate container and may be passed over a high surface to fluid interacting soap-like, replaceable cartridge made of at least one of an abrading, cleansing, polishing, and geriocidal material within the tissue separator structure prior to being directed at the tissue to be separated.

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.
