A method, system, and computer program for enabling parametric searches on source data using text search engine. A sheath covering the catheter body forms the anchoring and stabilizing devices, which sheath comprises slits cut into the sheath creating spines. The bump core includes an insulating resin layer and a conductive resin layer located on the insulating resin layer. If not so, the circuit is normal. These processes are realized with software by a DSP.
