Abstract

A method, system and device for securing conductive material on catheter elements for tissue sensing and cryogenic ablation. This may be used to deposit or embed conductive material onto or within polymeric materials. The method of manufacturing a balloon with conductive material may include extruding a polymeric material where the polymeric material includes embedded electrically conductive material. At least a portion of the polymeric material may be removed to expose at least a portion of the embedded electrically conductive material. The benefits may include allowing local bipolar recordings, contact assessment and ice thickness, and compatibility with 3-dimensional electroanatomical mapping systems.
