Cylindrical cage systems and methods for distributed tissue contact for mapping and ablation

Abstract

The disclosed technology includes a medical probe comprising a substantially cylindrical structure including a proximal circular base, a distal circular base substantially parallel to the proximal circular base, and plurality of spines extending along a longitudinal axis between the proximal circular base and the distal circular base, and a membrane positioned over the plurality of spines defining an internal volume about the longitudinal axis. The plurality of spines comprise a bifurcated portion positioned along at least a portion of the spine between the distal circular base and the proximal circular base. The membrane comprises one or more electrodes coupled to an external surface of the membrane. The membrane is configured to permit fluid communication from outside the membrane to the internal volume.
