Humanitarian Use Devices and Humanitarian Device Exemption

A Humanitarian Use Device (HUD) is a "medical device intended to benefit patients in the treatment or diagnosis of a disease or condition that affects or is manifested in not more than 8,000 individuals in the United States per year."  A Humanitarian Device Exemption (HDE) is an application that is similar to a premarket approval (PMA) application, but is exempt from the effectiveness requirements of the Food, Drug, and Cosmetic Act (FD&C Act).  FDA approval of an HDE authorizes an applicant to market a HUD subject to certain profit and use restrictions.  HUDs cannot be sold for profit, except in certain circumstances.

Under section 520(m)(6)(A)(i) of the FD&C Act, as amended by FDASIA, a HUD is only eligible to be sold for profit after receiving HDE approval if the device meets the following criteria:

1. The device is intended for the treatment or diagnosis of a disease or condition that occurs in pediatric patients or in a pediatric subpopulation, and such device is labeled for use in pediatric patients or in a pediatric subpopulation in which the disease or condition occurs; or

2. The device is intended for the treatment or diagnosis of a disease or condition that does not occur in pediatric patients or that occurs in  pediatric patients in such numbers that development of the device for such patients is impossible, highly impracticable, or unsafe.

If an HDE-approved device does not meet either of the eligibility criteria, the device cannot be sold for profit.

Impella RP System
Danvers, MA 01923

Approval for the Impella RP System. This device is indicated for providing circulatory assistance for up to 14 days in pediatric or adult patients with a body surface area >=1.5 m2 who develop acute right heart failure or decompensation following left ventricular assist device implantation, myocardial infarction, heart transplant, or open-heart surgery.

Plexision Inc
Pittsburg, PA
Approval for Pleximmune™. The Pleximmune™ test is intended to be performed at a single laboratory to measure the CD154 expression on T-cytotoxic Memory cells (TcM) in patient's peripheral blood lymphocytes (PBL) isolated from heparinized whole blood (anticoagulant – sodium heparin). The Pleximmune™ test is a qualitative prognostic test intended to be used in patients less than 21 years old with liver or small bowel transplantation. The Pleximmune™ test is an aid in the evaluation of the risk of acute cellular rejection (ACR) and must be used in conjunction with biopsy, standard clinical assessment and other laboratory information.
The Pleximmune™ test is intended for use at the following time periods:
  1. Pre-transplantation period: For blood samples collected before transplantation, the test predicts the risk of transplant rejection within 60 days after transplantation; and
  2. Early and late post-transplantation period: For blood samples collected within 60 days (early) after transplantation and for blood samples collected at 200 or more days (late) after transplantation, the test predicts the risk of transplant rejection within 60 days after sampling.
Kaneka Liposorber® LA-15 System
Kaneka Pharma America LLC
Approval for the Kaneka Liposorber® LA-15 System.  The device is indicated for use in the treatment of pediatric patients with nephrotic syndrome associated with primary focal segmental glomerulosclerosis, when: 1) Standard treatment options, including corticosteroid and/or calcineurin inhibitors treatments, are unsuccessful or not well tolerated and the patient has a GFR ≥ ml/min/1.73m2; or 2) The patient is post renal transplantation.
Berlin Heart EXCOR® Pediatric Ventricular Assist Device (VAD)

  • Tetralogy of Fallot
  • Truncus Arteriosus
  • Transposition with Ventricular Septal Defect (VSD)
  • Pulmonary Atresia

In addition, the conduit is indicated for the replacement of previously implanted, but dysfunctional, pulmonary homografts or valved conduits.

Medtronic Activa Dystonia Therapy
Medtronic Neurological
For unilateral or bilateral stimulation of the internal globus pallidus (GPi) or the subthalamic nucleus (STN) to aid in the management of chronic, intractable (drug refractory) primary dystonia, including generalized and/or segmental dystonia, hemidystonia, and cervical dystonia (torticollis) in patients seven years of age or above
