Abstract
A tissue detection and location identification apparatus can include, a first electrically conductive layer surrounding a lumen, an insulating layer surrounding the first electrically conductive layer, and a second electrically conductive layer circumferentially surrounding the insulating layer, where the insulating layer can electrically isolate the first electrically conductive layer from the second electrically conductive layer. A further insulating layer can surround the second electrically conductive layer. The first electrically conductive layer, the insulating layer, and the second electrically conductive layer can form a structure which has a first side and a second side disposed opposite to the first side with respect to the lumen, where the first side can be longer than the second side thereby forming a sharp pointed end via the first side at a distal-most portion. The exemplary configuration can be used for determination/detection of a tissue type, and/or determination of a location of insertion device/apparatus.
