摘要： An apparatus includes a shaft and an end effector at a distal end of the shaft. The end effector is sized to fit in an anatomical passageway within a subject's cardiovascular system. The end effector includes at least one electrode pair that is configured to contact cardiovascular tissue and thereby pick up electrocardiogram signals. Each electrode pair includes first and second electrodes spaced apart along a longitudinal axis from each other by a gap area located between the electrodes, the gap area having a gap length with respect to the longitudinal axis such that a length of one of the electrodes along the longitudinal axis is equal to or greater than the gap length, and a ratio of an area defined by the gap area to one electrode area is equal to or less than one.

摘要： The disclosed technology includes a medical probe comprising a plurality of spine members that form a substantially cylindrical structure. Each spine is stamped from a continuous piece of flat stock and heat-treated to a configuration including a first section extending along a longitudinal axis from a first end to a first bend, a second section extending from the first section curvilinearly with respect to the longitudinal axis and comprising a bifurcation point, and a third section extending along the longitudinal axis from a second bend to a second end so that a proximal portion of the third section is generally parallel to the first section. The second section comprises a continuous leg and a discontinuous leg. The continuous leg extends between the first section and the bifurcation point. The discontinuous leg extends towards the first section and terminates at a termination point between the bifurcation point and the first end.
