A minimally invasive medical assembly for ablating tissue, the assembly comprising: a delivery device configured to provide access to a target site within a hollow body of a patient through the tortuous anatomy within a lung, the delivery device comprising a working channel for delivering a pair of individually deliverable ablation devices (16a, 16b) to the target site; wherein each of the pair of individually deliverable ablation devices (16a, 16b) comprises: a nonconductive, expandable distal applicator tip defining an interior chamber and also defining a plurality of ports, at least one of the plurality of ports configured to allow passage of a conductive fluid from the interior chamber to an exterior surface of the distal applicator tip; an inflatable member disposed within the interior chamber of the distal applicator tip, the inflatable member configured to transition from a collapsed configuration to an expanded configuration and cause the distal applicator tip to correspondingly transition from a collapsed configuration to an expanded spherical shape; and a conductive wire disposed along at least a portion of an exterior surface of the distal applicator tip and configured to conduct energy to be carried by a conductive fluid passing through one or more of the plurality of ports; wherein the pair of ablation devices (16a, 16b) are coupled to one another by way of a pull wire, and wherein upon application of a pulling force upon the pull wire, at least the applicator tips of the ablation devices (16a, 16b) are configured to correspondingly move relative to one another. a delivery device configured to provide access to a target site within a hollow body of a patient through the tortuous anatomy within a lung, the delivery device comprising a working channel for delivering a pair of individually deliverable ablation devices (16a, 16b) to the target site; wherein each of the pair of individually deliverable ablation devices (16a, 16b) comprises: a nonconductive, expandable distal applicator tip defining an interior chamber and also defining a plurality of ports, at least one of the plurality of ports configured to allow passage of a conductive fluid from the interior chamber to an exterior surface of the distal applicator tip; an inflatable member disposed within the interior chamber of the distal applicator tip, the inflatable member configured to transition from a collapsed configuration to an expanded configuration and cause the distal applicator tip to correspondingly transition from a collapsed configuration to an expanded spherical shape; and a conductive wire disposed along at least a portion of an exterior surface of the distal applicator tip and configured to conduct energy to be carried by a conductive fluid passing through one or more of the plurality of ports; wherein the pair of ablation devices (16a, 16b) are coupled to one another by way of a pull wire, and wherein upon application of a pulling force upon the pull wire, at least the applicator tips of the ablation devices (16a, 16b) are configured to correspondingly move relative to one another. a nonconductive, expandable distal applicator tip defining an interior chamber and also defining a plurality of ports, at least one of the plurality of ports configured to allow passage of a conductive fluid from the interior chamber to an exterior surface of the distal applicator tip; an inflatable member disposed within the interior chamber of the distal applicator tip, the inflatable member configured to transition from a collapsed configuration to an expanded configuration and cause the distal applicator tip to correspondingly transition from a collapsed configuration to an expanded spherical shape; and a conductive wire disposed along at least a portion of an exterior surface of the distal applicator tip and configured to conduct energy to be carried by a conductive fluid passing through one or more of the plurality of ports; wherein the pair of ablation devices (16a, 16b) are coupled to one another by way of a pull wire, and wherein upon application of a pulling force upon the pull wire, at least the applicator tips of the ablation devices (16a, 16b) are configured to correspondingly move relative to one another.
