SYSTEMS AND METHODS FOR HIGH-RESOLUTION MAPPING OF TISSUE

摘要

According to some embodiments, methods and systems of enhancing a map of a targeted anatomical region comprise receiving mapping data from a plurality of mapping electrodes, receiving high-resolution mapping data from a high-resolution roving electrode configured to be moved to locations between the plurality of mapping electrodes, wherein the mapping system is configured to supplement, enhance or refine a map of the targeted anatomical region or to directly create a high-resolution three-dimensional map using the processor receiving the data obtained from the plurality of mapping electrodes and from the high-resolution roving electrode.

主权项

1. A device for high-resolution mapping and ablating targeted tissue of subject, comprising:
an elongate body comprising a proximal end and a distal end; a first high-resolution electrode portion positioned on the elongate body; at least a second electrode portion positioned adjacent the first electrode portion, the first and second electrode portions being configured to contact tissue of a subject and deliver radiofrequency energy sufficient to at least partially ablate the tissue; and at least one electrically insulating gap positioned between the first electrode portion and the second electrode portion, the at least one electrically insulating gap comprising a gap width separating the first and second electrode portions; wherein the device is configured to be positioned within targeted tissue of the subject to obtain high-resolution mapping data related to said tissue when ablative energy is not being delivered via the first and second electrode portions; and wherein the device is used as a roving device in conjunction with a separate mapping device or system to provide mapping data in tissue regions not adequately covered by said separate mapping device or system, wherein the separate mapping device or system comprises a plurality of mapping electrodes.
