A catheter having an elongate body, at least two elongate stimulation members extending from the elongate body, at least one electrode on each of the elongate stimulation members, where the electrodes form an electrode array that receives and conducts electrical current. The elongate stimulation members curve only in the first volume defined at least in part by a first plane, and a second volume defined at least in part by the first plane and being opposite the first volume can contain no electrodes. The catheter can further include a position gauge having a marking that indicates a length between a second end of the elongate body and a bumper end of the position gauge. The catheter can also include a pulmonary artery catheter having a lumen, where the catheter extends through the lumen of the pulmonary artery catheter. |

1. A catheter for treating acute heart failure by applying electrical neuromodulation, the catheter comprising:
an elongate body having a first end, a second end, and a longitudinal axis, a first plane including the longitudinal axis; at least two elongate stimulation members configured to extend from the elongate body, each of the at least two elongate stimulation members comprising an electrode, each of the at least two elongate stimulation members configured to curve into a first volume on a first side of the first plane to form an electrode array in the first volume, at least one of the at least two elongate stimulation members including:
a stimulation member elongate body; anda first portion of a wire extending longitudinally through the stimulation member elongate body, the first portion of the wire distal to a second portion of the wire extending longitudinally through the elongate body,wherein application of pressure by the wire against the stimulation member elongate body at or near a distal end of the stimulation member elongate body causes the wire to deflect to impart the curve to the at least one elongate stimulation member; conductive elements extending through each of the at least two elongate stimulation members, the conductive elements configured to conduct electrical current to combinations of two or more of the electrodes in the electrode array; an anchor member configured to extend from the elongate body into a second volume on a second side of the first plane, the second side opposite the first side, wherein the anchor member does not include an electrode; a sensor comprising at least one of a blood oxygen sensor, a pressure sensor, and an integrated circuit; and a sensor conductive element extending through the elongate body, the sensor conductive element configured to conduct electrical signals from the sensor. |
