Expandable RF Electrode Balloon Dynamics

The electrode transitions from a fixed rigid structure to a dynamic expandable structure. The conductor is wrapped around an expandable balloon, allowing the electrode to change its conduction area from small during insertion to large during treatment. This dynamic adaptation resolves the contradiction by enabling concentrated heating at the target site while maintaining efficiency for wide area treatment through balloon expansion.

The conductor is nested around the balloon, with the balloon serving as a core structure that can be expanded. This nested configuration allows the electrode to be inserted in a compact form and then expanded to cover a wider treatment area, simultaneously achieving heating precision at the target site and improved radiofrequency current efficiency across the expanded surface.

The electrode system transitions from a permanently bent rigid structure to a dynamically expandable structure. During insertion, the electrode remains in a compact state that avoids interference with normal tissue. Once positioned at the target site, the balloon expands to provide a large conduction area for effective treatment, thereby achieving both wide conduction area and reduced tissue damage risk.

The electrode is segmented into multiple conductors (first, second, third conductors) that can be independently controlled. This segmentation allows selective activation of conductors based on the treatment area needed, enabling wide conduction area when necessary while minimizing tissue interference by activating only the required segments during insertion and navigation.

The electrode components are nested within the balloon structure during manufacturing, which simplifies the assembly process. The conductors are wrapped around the balloon in a systematic manner, making the manufacturing process more straightforward. The nested configuration also allows the electrode to be inserted in a compact form through narrow lumens, then expanded at the target site for treatment.

The electrode incorporates an expandable balloon structure that transitions from a compact insertion state to an expanded treatment state. This dynamic characteristic allows the electrode to navigate narrow bodily lumens easily during insertion while providing a large conduction area when expanded at the target site, thereby improving ease of operation without significantly complicating the manufacturing process.
