Tissue detection devices, systems and methods

A method for making an insertion arrangement, comprising:

• a) providing an insulating layer on a tubular hollow structure to form a first structure;
• b) providing a conductive layer to the first structure to form a second structure;
• c) cutting the second structure to a predetermined length to form a third structure;
• and
• d) producing a predetermined shape at a distal end of the third structure by at least one of cutting or grinding at least one end of the third structure so as to form the insertion arrangement which includes a conductive portion at or near at least one end thereof that is at least partially separated from the tubular hollow structure via at least one portion of the insulating layer,
• wherein the conductive portion is formed based on the conductive layer, and the insulating portion is formed based on the insulating layer.
