No.
The device is a filter for water purification in dialysis machines, not a device directly applied to the patient for treatment.
No
The device is a filter designed to purify water for dialysis machines by removing bacteria and endotoxins; it does not diagnose medical conditions.
No
The device description clearly states it is a physical filter cartridge made of polypropylene casing and membranes, which are hardware components.
Based on the provided information, the RenaPure filter is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to filter water used in hemodialysis to remove bacteria and endotoxin. This is a water purification process, not a diagnostic test performed on a biological sample from a patient.
- Device Description: The device is a filter cartridge designed to physically remove contaminants from water. It does not involve any reagents, assays, or analysis of biological specimens.
- Lack of Diagnostic Function: The device does not provide any information about a patient's health status, disease, or condition. Its function is solely related to the quality of the water used in a medical procedure.
IVD devices are typically used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The RenaPure filter does not perform any such function.
N/A
Intended Use / Indications for Use
The RenaPure filter is a bacterial and endotoxin retentive filter intended for use in a centralized loop as the final step of a water purification cascade to provide standard dialysis water to machine servicing multiple patients. This filter is not intended to service as the sole means of water purification and therefore must be used in conjunction with other water treatment equipment.

Device Description
The RenaPure filter is a 20" cartridge style filter in a polypropylene casing that contains dual-layered, 0.22 micron polyethersulfone (PES) pleated membranes which are separated by polypropylene screen layers. The PES membrane is charge modified with a positive charge coating, similar to the predicate device, that aids in removal of endotoxin by charge attraction. Filter configurations are based on an industry standard 222 header design with silicone O-rings at the open end of the filter and flat or fin end caps at the closed end. The filter cartridge is installed in a durable filter housing and operates in a dead-end mode. The filter is designed to remove bacteria and endotoxin from water used in hemodialysis with similar water flow characteristics as the predicate device. The filter provided non-sterile.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance (bench) testing has been performed which included (a) Flow/Pressure Drop measurements, (b) Endotoxin Retention, (c) Bacterial Retention, (d) Compatibility to Hot Water and Chemical Disinfections, (e) Housing Fit tests, and (f) Compatibility with Deionized water. Testing demonstrated that the RenaPure filter met the intended design requirements and will operate as a drop-in replacement to the predicate device.
A series of biocompatibility tests was performed on the RenaPure filter based on it being used as an externally communicating, indirect blood contact device. This testing also included an exhaustive extraction test to identify extractables/leachables from the RenaPure filter followed by a toxicological risk assessment. Additional biocompatibility tests were performed after exposing the RenaPure to simulated hot water disinfection and chemical disinfection routines. All biocompatibility testing passed and the risk of any toxic leachates from the RenaPure filter were considered negligible.

Dear Robert Dudek:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

| Trade Name | RenaPure® Filter |
| Classification Name | Water purification system for hemodialysis, 21 CFR 876.5665 |
| Device Class | Class II |

| Product Code | FIP |
| Predicate Device | Gambro Posiclear Filter - K061782 |
| Device Description | The RenaPure filter is a 20" cartridge style filter in a polypropylene casing that
contains dual-layered, 0.22 micron polyethersulfone (PES) pleated
membranes which are separated by polypropylene screen layers. The PES
membrane is charge modified with a positive charge coating, similar to the

configurations are based on an industry standard 222 header design with
silicone O-rings at the open end of the filter and flat or fin end caps at the
closed end. The filter cartridge is installed in a durable filter housing and
operates in a dead-end mode. The filter is designed to remove bacteria and
endotoxin from water used in hemodialysis with similar water flow

provide standard dialysis water to machine servicing multiple patients. This
filter is not intended to service as the sole means of water purification and
therefore must be used in conjunction with other water treatment equipment. |
| Technological
Characteristics | Retention of bacteria by size exclusion (membrane pore size) and retention of
endotoxin by charge attraction (charge modified membrane) is achieved in
the same way for both the RenaPure filter and the predicate device. Materials
of construction are similar to the predicate device, with the exception that a
polyethersulfone base membrane is used, this providing better heat stability
for hot water disinfection routines performed during use of the device. |
| Non-clinical
Performance
Assessment | Performance (bench) testing has been performed which included (a) |
| | Flow/Pressure Drop measurements, (b) Endotoxin Retention, (c) Bacterial |
| | Retention, (d) Compatibility to Hot Water and Chemical Disinfections, (e)
Housing Fit tests, and (f) Compatibility with Deionized water. Testing
