What this trial studies

This study aims to assess the safety and effectiveness of the Insight Pro Device in detecting lymphatic and venous disorders such as lymphedema and chronic venous insufficiency. It involves measuring extracellular fluid volume and skin hardness using advanced bioimpedance and durometer techniques. Participants will include individuals with edema as well as healthy controls to compare results. The study will monitor adverse events to ensure the device's safety during use.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with unilateral or bilateral extremity edema who are at least three months post-cancer treatment.

Not a fit: Patients with active or recurrent cancer, open wounds, or those unable to participate in the study protocol may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive and effective diagnostic tool for patients suffering from lymphatic and venous disorders.

How similar studies have performed: While this approach is innovative, similar studies evaluating bioimpedance for fluid detection have shown promise, indicating potential for success.
