Brief summary
The purpose of this study is to demonstrate safety and performance of AquaPass System for enhancing fluid transfer through the skin, by increased sweat rate, in edematous patients.
Detailed description
This is a prospective, single-center, open label single arm study, conducted in two phases: up to 6 healthy subjects (Phase 1) and up to 16 chronic heart failure (CHF) patients (Phase 2). After being informed about the study, requirements and potential risks, consenting patients will be enrolled and undergo 3 procedures (each procedure up to 3 (±1) hours operation), with 4-10 days between each procedure. All patients will be followed up for 7 (±2) days from final procedure.
Interventions
The AquaPass device is a capsule that creates relatively homogenous temperature around the patients' lower body, while controlling and maintaining at a low percentage the relative humidity within the capsule thus enabling controlled environment that enhances sweat rate.
