Brief summary

This is a prospective, multi-center, open-label, single-arm feasibility trial to assess device safety and efficacy of the Cordella™ Heart Failure System in 10 NYHA Class III heart failure patients who will receive the Cordella™ Sensor implant.

Detailed description

The objectives of this study are to establish that the Cordella™ Sensor can be safely delivered, deployed, and remain stable within the target pulmonary artery (PA) segment through 30 days post-implant as well as to measure the accuracy of Cordella™ Sensor PA pressure measurements compared with fluid-filled catheter PA pressure measurements obtained by standard right heart catheterization (RHC) at 90 days post implant. Safety measures will include the frequency and rates of adverse events, both overall and for each specific event, which will be collected throughout the study. Subjects will remain in this trial for 24 months.

Interventions

The Cordella™ Heart Failure System collects, records, and transmits physiologic data and communications from the patient at home to clinicians for assessment, patient communication, and patient-centered heart failure management. The system consists of the following components: 1. myCordella™ Patient Management Portal 2. myCordella™ Hub 3. myCordella™ Peripherals, including the Cordella™ Pulmonary Artery Sensor System (CorPASS)

Subject has sufficient Cellular and/ or Wi- Fi Internet coverage at home 12. Subject agrees to return to the treating Investigator for all scheduled follow up visits and can return to the hospital for follow up 13. Subject compliance as defined by data collection and transmissions at least 5 days a week (does not have to be consecutive days) using the myCordella™ Hub & Peripherals for at least 1 week during the screening period

Exclusion criteria

Subjects with an indwelling inferior vena cava (IVC) filter 19. Subjects who are pregnant or breastfeeding 20. Subjects whose clinical condition, in the opinion of the Investigator, makes them an unsuitable candidate for the study 21.
