ABSTRACT:
A system for detecting tissue contact and penetration depth. The system comprises a needle sheath having a needle sheath inner diameter and a needle sheath outer diameter. A first conductive region is disposed on the needle sheath inner diameter. A needle having a needle insulation layer on the outer diameter upon which a second conductive region is disposed within the first conductive region. A dielectric layer is disposed between the first conductive tube and the second conductive tube. A capacitance sensor is coupled to the first conductive region and the second conductive region.
