Brief Summary:

1. Summary of Clinical Investigation

A summary of the clinical investigation is provided below and includes the primary objective of the study, the safety and feasibility endpoints, the number of subjects to be enrolled, the study duration, the subject follow-up and the inclusion/exclusion criteria.

  1. Primary Objective

    The primary objective of the study is to evaluate the safety and feasibility of the alfapump® System indication for use in the management of fluid in NYHA Class III and ambulatory NYHA Class IV heart failure patients who have an eGFR of > 15 to < 60 mL/min/1.73m2.

  2. Study Endpoints

    1. Primary Safety Endpoint

      The primary safety endpoint will be an assessment of the occurrence of adverse events (AEs) and serious adverse events (SAEs) related to:

      1. Surgical implant of the alfapump®
      2. Device malfunctions
      3. Dialysate infusion
    2. Secondary Safety Endpoints

      The secondary endpoint will be an assessment of:

      1. Time to first hospitalization related to fluid management after the activation of the alfapump® System and initiation of dialysate infusion has occurred
      2. Rate of occurrence of re-hospitalizations related to fluid management
      3. All-cause mortality
    3. Assessment of Feasibility for Fluid Management in Heart Failure Indication The feasibility of the alfapump® System for management of fluid in NYHA Class III and ambulatory NYHA Class IV heart failure patients with renal dysfunction will be assessed by the net fluid balance as measured by the ability of the alfapump® System to move more fluid to the bladder than dialysate instilled.

Enrollment Exclusion Criteria

  • Patients presenting with acute decompensated heart failure requiring hospitalization for management of their symptoms (i.e. hospitalization for exacerbation of chronic heart failure manifested by signs and symptoms requiring intravenous and/or more aggressive therapy)
  • Patients with ascites on physical examination resulting predominantly from right heart failure
  • Patients who have an indication for and are candidates for CRT but who have not been treated with CRT
