What unique design characteristic does Sphere 9 possess for energy delivery?

Sphere 9 features a unique design characterized by a single spherical electrode, which is integral to its mechanism for energy delivery. This spherical configuration allows for a more uniform distribution of energy across the treatment area, maximizing efficacy while minimizing potential damage to surrounding tissues. The design promotes an optimal focal point for ablation, enhancing the precision of energy application. Such a characteristic is particularly beneficial in medical procedures requiring careful targeting, as it allows clinicians to achieve desired outcomes effectively and safely.

In contrast, other designs like multi-channel delivery, rectangular arrays, or circular rings may offer different benefits or applications but do not encapsulate the distinctive attributes and advantages that a single spherical electrode provides in the context of Sphere 9's purpose and functionality.
