Mapping probe assembly with skived tube body frame

摘要

An embodiment of a mapping probe assembly includes a body frame with a lumen therein. The body frame includes a catheter shaft region, a loop section and a transition region between the catheter shaft region and a loop section. A plurality of mapping electrodes are attached around the loop section. Electrical conductors extend through the lumen of the body frame to the mapping electrodes. In some embodiments, the loop section is skived, where a portion of the body frame is removed toward the interior of the loop section. The loop section has a generally planar loop, and further has a loop center. In some embodiments, the catheter shaft has an alignment generally perpendicular to the loop section where the alignment of the catheter shaft is along a line that intersects the planar loop proximate to the loop center.

1. A probe assembly comprising:
a body frame with a lumen therein, the body frame including a catheter shaft region, a loop section, and a transition section where the body frame changes direction between the shaft region and the loop section, wherein at least a portion of the body frame is removed in the loop section, wherein the portion of the body frame that is removed is toward an interior of the loop section, wherein the body frame defining an exterior of the loop section is free of openings; and a plurality of electrodes attached around the loop section.
