provides a more relevant image to the operator who is interested in the tissue that is closer to the opening of the device fig2 d is a front view of the subject invention illustrating the full lumen access upon opening of the leaflet as was mentioned before fig3 a shows the lower leaflet of the subject invention 300 that is capable of performing ablation and cauterization of the tissue this embodiment of the subject invention is intended to take a partial bite of the tissue which makes it easier to remove the dissected tissue that would be contained within the space between the two leaflets when the leaflets are closed and the tissue that 39 s contained between the leaflets is separated from the surrounding area and the leaflets are touching alongside their length in procedures where the operator is dependent on the clear visualization cauterizing of the remaining surface of the dissected tissue prevents bleeding and creating turbidity in the irrigating fluid and thereby clouding the view the leaflet can be made out of many different materials as described before element 310 represents the lower leaflet that could be metallic or transparent or translucent as described before element 340 represents the portion of the lower leaflet which is conducive to electrical energy and in cooperation with the upper leaflet is utilized to resect the tissue by radio frequency element 330 is a high temperature non conductive material with an expansion coefficient that is properly chosen to minimize the relative motion between elements 310 330 340 examples of such materials include ceramics polyimide polysulfone silicone and other materials that have the qualities.
