摘要： An end effector having loop members with electrodes thereon and are usable with catheter-based systems to measure or provide electrical signals. The end effector can include three loop members that are non-coplanar when expanded unconstrained that become contiguous to a planar surface when the loop members are deflected against the surface, a mechanical linkage that joins the loop members at a distal vertex of the end effector. The end effector may have a lateral gap length between laterally adjacent electrodes approximately twice that of a longitudinal gap length between longitudinally adjacent electrodes. In some configurations, longitudinal electrode bipole pairs having a gap distance approximately equal to the lateral gap distance may be provided by bypassing every other electrode in the longitudinal direction.

摘要： An end effector for a catheter that can include a flexible circuit layer extending along a longitudinal axis from a proximal portion to a distal portion, a framework extending generally parallel to the flexible circuit layer along the longitudinal axis from the proximal to the distal portion, and a flexible polymer layer encapsulating both the framework and the flexible circuit layer. The flexible circuit layer can include a first surface and a second surface opposite the first surface.

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.
