Patent ID: 8320987

Claim:
A electric potential mapping and electrode attachment device comprising: an outer cylinder; an inner cylinder; a first electrical connection located on the outer surface of said outer cylinder; a second electrical connection located on the outer surface of said outer cylinder; a inner cylinder-to-electrode lead mechanical connection means; a inner cylinder-to-electrode lead resilient electrical connection; and a outer cylinder-to-electrode lead electromechanical connection means; wherein, said outer and inner cylinders are mounted concentrically to each other on a common longitudinal center axis with said inner cylinder fitting completely inside of said outer cylinder so that each cylinder may be rotated relative to the other and said common longitudinal axis is void or hollow and sized to accept by threading there through a certain laparoscopic device, said outer cylinder has at least one void or hole through which said inner cylinder may be rotated by thumb or finger relative to said outer cylinder; said inner cylinder-to-electrode lead mechanical connection means provides a reversible rigid mechanical connection between said inner cylinder and a first contact on the electrode lead so that rotation of said inner cylinder causes rotation of the first contact on electrode lead, said inner cylinder-to-electrode lead resilient electrical connection electrically connects said first electrical connection to the first contact on electrode lead wherein said inner cylinder-to-electrode lead mechanical connection means maintains electrical connectivity with the first contact on electrode lead when mechanically connected to such, said resilient electrical connection means electrically connects said inner cylinder-to-electrode lead mechanical connection means to said first electrical connection and maintains such electrical connection during repeated and complete rotation of said inner cylinder-to-electrode lead mechanical connection means, where said resilient electrical connection is a resilient, flexible, or plastic connection that remains electrically conductive to maintain electrical and physical contact between said first electrical connection and said inner cylinder-to-electrode lead mechanical connection means, and said outer cylinder-to-electrode lead electromechanical connection means mechanically and rigidly connects said outer cylinder to a second contact on the electrode lead and also electrically connects said second electrical connection to the second contact on electrode lead.
