An over shoe for use with electrosurgical instruments having a pair of juxtaposed jaw members pivotably associated with one another, at least one of which includes an electrically conductive surface disposed thereon which is in electrical engagement with an electrosurgical energy source. According to one aspect of the present disclosure, the over shoe includes a tissue contacting wall configured and dimensioned to selectively and substantially overlie the electrically conductive surface of the electrosurgical instrument. The tissue contacting wall is fabricated from a non-conductive material and includes a plurality of apertures formed therethrough. In another embodiment, the tissue contacting wall is electrically conductive and is configured for selective engagement atop on of the jaw members.
1. An over shoe selectively positionable on at least one jaw member of an electrosurgical instrument, the over shoe comprising: a tissue contacting wall configured to overlay a tissue contacting surface of the at least one jaw member and having at least one aperture defined therein;a first wall enga
1. An over shoe selectively positionable on at least one jaw member of an electrosurgical instrument, the over shoe comprising: a tissue contacting wall configured to overlay a tissue contacting surface of the at least one jaw member and having at least one aperture defined therein;a first wall engaged with the tissue contacting wall; anda second wall engaged with at least one of the tissue contacting wall or the first wall;wherein inner surfaces of the tissue contacting wall, the first wall, and the second wall are configured to frictionally retain the over shoe on the at least one jaw member of the electrosurgical instrument. 2. The over shoe according to claim 1, wherein the tissue contacting wall is substantially planar. 3. The over shoe according to claim 1, wherein the at least one aperture includes at least two apertures, and wherein each aperture is evenly sized. 4. The over shoe according to claim 1, wherein each aperture of the at least one aperture is circular. 5. The over shoe according to claim 4, wherein each aperture has a diameter of between 10 μm and 1000 μm. 6. The overshoe according to claim 1, wherein each aperture of the plurality of apertures is an elongated slot. 7. The over shoe according to claim 1, wherein the tissue contacting wall is formed from a conductive material. 8. The over shoe according to claim 1, wherein the tissue contacting wall is formed from a non-conductive material. 9. The over shoe according to claim 1, further comprising a protrusion extending from the tissue contacting wall and configured to electrically communicate with an electrode of a first jaw member of the at least one jaw member when the overshoe is selectively positioned on the first jaw member. 10. The over shoe according to claim 9, wherein the protrusion is configured to create a pattern of tissue welds for treating tissue. 11. The over shoe according to claim 9, wherein the protrusion is coated with a non-stick material, wherein the non-stick material is selected from the group consisting of nickel-chrome, chromium nitride and tin-nickel. 12. The over shoe according to claim 1, further comprising a longitudinally oriented slot defined in the second wall. 13. An over shoe selectively positionable on at least one jaw member of an electrosurgical instrument, the over shoe comprising: a material configured to overlay a tissue-contacting surface of at least one jaw member of the electrosurgical instrument, the material having a tissue-contacting wall and an inner surface, the material including at least one aperture extending between the tissue-contacting wall and the inner surface;wherein the inner surface of the tissue-contacting wall is configured to frictionally retain the over shoe on the at least one jaw member of the least one jaw member of the electrosurgical instrument. 14. The over shoe according to claim 13, wherein the material is a conductive material. 15. The over shoe according to claim 13, wherein the at least one aperture includes at least two apertures, and wherein each aperture is evenly sized. 16. The over shoe according to claim 9, wherein the protrusion is coated with a non-stick material including nickel-chrome.
