Lymph Node Location System During Sentinel Biopsy Procedure

Page Type
Product Code
Definition
Locating lymph nodes draining a tumor as part of the sentinel lymph node biopsy procedure
Physical State
The solution is considered a combination product. The iron particle is surrounded by a carboxydextran coating. The carboxydextran coating is considered a drug. The nanoparticles are then mixed in a saline solution. The system uses an electronic base device with a magnetic probe.
Technical Method
The solution is composed of iron nanoparticles which is injected peri-tumor. The nanoparticles are taken up by the lymphatic system and remains there. The magnetic probe is used to locate the iron nanoparticles which should collect in the lymph nodes.

No Linked CFR Text

The FDA has not linked product code PUV 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.
