Catheter localization using fiber optic shape sensing combined with current location

An apparatus includes a shaft, a flexible distal-end assembly, two or more sensing-electrodes, and a fiber-optic 5 shape sensor. The shaft is configured for insertion into a body of a patient. The flexible distal-end assembly is fitted at a distal end of the shaft. The two or more sensing-electrodes...

More Information
Summary:An apparatus includes a shaft, a flexible distal-end assembly, two or more sensing-electrodes, and a fiber-optic 5 shape sensor. The shaft is configured for insertion into a body of a patient. The flexible distal-end assembly is fitted at a distal end of the shaft. The two or more sensing-electrodes are disposed over the distal-end assembly and are configured to generate signals indicative 10 of positions of the sensing-electrodes in the body. The fiber-optic shape sensor is coupled to a portion of the distal-end assembly, wherein the two or more sensing electrodes have a-priori known distances from a known location over the fiber-optic shape sensor, and wherein the 15 fiber-optic shape sensor is configured to provide an indication of a spatial deformation of the flexible distal end assembly. 60,, Apply 62 PureACL 63 Ap Reposition 71 Catheter
