The disclosed technology includes a medical probe comprising a tubular shaft having a proximal end and a distal end, the tubular shaft extending along a longitudinal axis. The medical probe further comprises an expandable basket assembly coupled to the distal end of the tubular shaft. The basket assembly includes a plurality of electrodes with each electrode of the plurality of electrodes having a lumen therethrough. The basket assembly further includes a plurality of spines extending along the longitudinal axis and configured to bow radially outward from the longitudinal axis when the expandable basket assembly is transitioned from a collapsed form to an expanded form. Each spine includes a proximal and a distal end and a strut passing through the lumen of an electrode. The strut includes a mechanical retainer disposed on the strut to prevent the electrode from sliding proximally or distally along a length of the spine.

The disclosed technology includes a medical probe including a tubular shaft having a proximal end and a distal end. The tubular shaft can extend along a longitudinal axis. The medical probe can include an expandable basket assembly proximate the distal end of the tubular shaft. The expandable basket assembly can include a single spine comprising a resilient material extending generally linearly along the longitudinal axis in a collapsed form and forming a spiral member defining a generally spherical outer periphery in an expanded form. One or more electrodes can be coupled to the single spine. Each electrode can include a lumen offset with respect to a centroid of the electrode so that the single spine extends through the lumen of each of the one or more electrodes.

Systems and methods for a single spiral electrode assembly forming a spherical basket for improved tissue contact and current delivery

The disclosed technology includes a medical probe comprising a tubular shaft extending along a longitudinal axis and including a proximal end and a distal end. The medical probe further comprises an expandable basket assembly proximate the distal end of the tubular shaft. The basket assembly comprises a first unitary tripodic structure and a second unitary tripodic structure, each tripodic structure formed from a respective planar sheet of material that includes three linear spines converging at a respective central spine intersection and one or more electrodes coupled to each of the spines, each electrode defining a lumen through the electrode so that the spine extends through the lumen of each of the one or more electrodes. Each tripodic structure formed from a respective planar sheet of material that includes three linear spines converging at a respective central spine intersection.
