Patent Description:
A forceps is a plier-like device that includes a jaw assembly for effecting an anatomical feature. For example, a forceps can be used to grip, capture, grasp, manipulate, pull, constrict, cut, and/or dissect an anatomical feature such as a vessel or tissue. Some forceps also include electrosurgical capabilities so that anatomical feature can be cut and/or coagulated with one or more therapy currents.

Some forceps can be used to cut or dissect an anatomical feature via one or more blunt dissection techniques. One blunt dissection technique is sweep dissection. In sweep dissection, the jaw assembly, or a portion of the jaw assembly, such as an edge, is moved or "swept" across the anatomical feature thereby cutting or dissecting the anatomical feature.

Opportunities exist for improving such devices. For example, it may be desirable to have a medical device for effectively coagulating, cutting, and/or dissecting an object or anatomical feature between the jaws, and also for effectively cutting or dissecting an anatomical feature via sweep dissection. Some examples of known medical devices are disclosed in <CIT><CIT> and <CIT>; <CIT>, <CIT>, and <CIT>; and in <CIT>.

The second jaw body <NUM> has a floating polarity (e.g. 'o').

In another form, with continued reference to <FIG>, the second jaw body <NUM> has a first polarity (e.g. '-') and the sealing plate <NUM> has a second polarity (e.g. '+'), or vice versa.

Thus, an expression in the Detailed Description of the Teachings of a range in terms of at "'x' parts by weight of the resulting polymeric blend composition" also contemplates a teaching of ranges of same recited amount of "x" in percent by weight of the resulting polymeric blend composition.

Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints. The use of "about" or "approximately" in connection with a range applies to both ends of the range. Thus, "about <NUM> to <NUM>" is intended to cover "about <NUM> to about <NUM>", inclusive of at least the specified endpoints.

The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. The term "consisting essentially of" to describe a combination shall include the elements, ingredients, components or steps identified, and such other elements ingredients, components or steps that do not materially affect the basic and novel characteristics of the combination. The use of the terms "comprising" or "including" to describe combinations of elements, ingredients, components or steps herein also contemplates embodiments that consist essentially of the elements, ingredients, components or steps.
