Hemodialyzer, High Cut-Off

Page Type
Product Code
Definition
Removal of free light chains for the treatment of dialysis dependent acute renal failure secondary to cast nephropathy in patients with multiple myeloma.
Physical State
The high cut-off technology hemodialyzer is characterized by larger membrane pore sizes resulting in a nominal cut off-point of 100 kilo Daltons (kDa) allowing removal of circulating substances with molecular weights up to a value of approximately 45 kDa. The membrane material used in this device is polyarylethersulfone (PAES) with an effective membrane surface area of 2.1 m².
Technical Method
The high cut-off technology hemodialyzer is used on a conventional hemodialysis system with controlled ultrafiltration for the removal of free light chains. During therapy, anticoagulated blood taken from the patient flows via a tubing system through the high cut-off technology hemodialyzer and back into the patient's vascular system. Conventional dialysate solution is circulated in a counter-current direction through the dialysate compartment of the high cut-off hemodialyzer. To compensate for the removed fluid volume, a physiologic and isotonic replacement fluid is infused into the patient at a flow rate equal to or less than the filtrate flow rate.
Target Area
External communicating device in contact with circulating blood.

No Linked CFR Text

The FDA has not linked product code OVL to any particular section of the CFR (Code of Federal Regulations). There are multiple reasons why this might be the case:

  • The product code was created for a class III submission that does not follow the normal PMN or PMA path - e.g., for a device that falls under HDE (Humanitarian Device Exemption) or EUA (Emergency Use Authorization).
  • The FDA has generated the product code for an existing Class III device, as a result of a PMA supplement that modifies the device in a way that it can't fit under the existing product code originally assigned
  • The product code was created for internal use at the FDA, and not for classification or regulatory-related purposes.
