Details and patient eligibility

About

The present study is a first-in-man, single arm, open-label, single center study to assess feasibility and safety of a novel implantable device, LymphoPilot, in patients suffering from secondary upper limb or lower lymphedema.

Full description

The study consists in a first-in-man clinical investigation for LymphoPilot, an investigational implantable medical device. LymphoPilot is composed of an implanted part and an external wearable device. The implanted part (pump, drainage catheter and output catheter), is implanted in the subcutaneous tissue of the arm or leg and drains excess fluids to the supraclavicular or abdominal subcutaneous tissue, where fluids are naturally reabsorbed by the healthy lymphatic and venous system. The external part consists in a wearable controller used to activate the implanted pump.

The subcutaneous implantation of the device is performed in loco-regional or general anesthesia, in ambulatorial settings, and the patient is dismissed from the hospital on the same day of the procedure.

The device is activated in the postoperative room by placing the external wearable device on patient's limb, in proximity of the implanted pump. Patients are required to wear the external controller continuously throughout the study, except 30 minutes per day, to allow taking a shower/bath.

Follow-up visits are planned 1, 4 and 8 weeks after device implantation. The implanted device is removed with a surgical procedure in local anesthesia 8 weeks after device implantation, and 2 additional follow-up visits are planned after device removal.

Description:

Patient will be implanted with the medical device under investigation, LymphoPilot, through a surgical procedure performed in loco-regional or general anesthesia. Lymphedema outcomes will be monitored for 8 weeks after implantation and compared to baseline values before device implantation. Safety data will be collected throughout the study.
