Zusammenfassung:A medical system includes a sheath and a dilator. The sheath includes an elongate body having a proximal portion and a distal portion, and a lumen extending from the proximal portion to the distal portion. The dilator is movable within the lumen. The dilator includes an elongate body having a proximal portion, a pre-formed distal portion, and a tapered distal tip. One or more electroanatomical mapping electrodes are located on the pre-formed distal portion. The one or more electroanatomical mapping electrodes is configured to electrically couple with an electroanatomical mapping system. The pre-formed distal portion has a substantially linear configuration when confined in the sheath, and an arcuate configuration when unconfined.
