Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to objectively assess lymphatic function before, during, and immediately after Neuroglide treatment in lower trunk and leg lymphatic vessels, torso, axillary regions, inguinal regions, upper extremities, and cervical/neck and to determine any VAS (Visual Analog Scale, a commonly used measure of pain perception) score change after Neuroglide treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pneumatic Compression Therapy (PCT)

Group Type EXPERIMENTAL

Indocyanine green (ICG) dye

Intervention Type DRUG

ICG (25 mg vial) will be reconstituted with 10 ml sterile water provided by the manufacturer; further dilutions will be made in sterile saline just prior to administration. The final concentration of 0.32 millimolar (mM) will provide 25 μg ICG/injection, with each injection of 0.1 cc to be made . Up to 30 intradermal injections using conventional 30- or 31-gauge needles will be administered to each subject, for a maximum dose of 750 ug ICG, over 200 times less than the maximum allowed dose. Injection sites will be cleaned with alcohol wipes before intradermal injection.

NIRF-LI imaging

Intervention Type DEVICE

Near-infrared fluorescence lymphatic imaging (NIRF-LI) imaging will be done to assess the drainage of ICG laden lymph from ICG injection sites toward regional nodal basins for 60 minutes before, during and after the Neuroglide pad treatment

Neuroglide pad

Intervention Type DEVICE

After injection of Indocyanine green (ICG) dye and NIRF-LI imaging the subject will lie on the Neuroglide pad for the one-hour PCT treatment session.
