A Clinical Study to Evaluate the Effectiveness of a Novel Portable Non-Pneumatic Active Compression Device vs. an Advanced Pneumatic Compression Device for Treating Lower Extremity Lymphedema

A Multi-center Randomized Control Single Cross-over Study to Evaluate the Safety and Effectiveness of Dayspring, a Novel Portable Non-Pneumatic Active Compression Device (NPCD) vs. an Advanced Pneumatic Compression Device (APCD) for Treating Lower Extremity Lymphedema. To evaluate the Dayspring, a Novel Portable Non-Pneumatic Active Compression Device (NPCD) in contrast to an advanced pneumatic compression device (APCD) in a multi-centered setting to evaluate volume, quality of life, safety, adherence, and preference.

Inclusion criteria

• Males and females ≥ 18 years of age
• Capable and willing to sign the informed consent and deemed capable of following the study protocol

• Diagnosis of pulmonary embolism or deep vein thrombosis within the previous 6 months
• Diagnosis of pulmonary edema
• Diagnosis of congestive heart failure (uncontrolled/uncompensated)
• Diagnosis of chronic kidney disease with acute renal failure
• Diagnosis of epilepsy
• Subjects with poorly controlled asthma
• Any condition where increased venous and lymphatic return is undesirable
• Women who are pregnant, planning a pregnancy or nursing at study entry
• Participation in any clinical trial of an investigational substance or device during the past 30 days
