Device Description
Clave Neutral-Displacement Connectors are needlefree, bi-directional connectors that utilize a pre-slit septum which prevents microbial ingress when in the un-activated state and allows access to the fluid path when activated with an ISO 80369-7 compliant male luer. The septum offers neutral displacement of fluid during connection or disconnection of a male luer and self-seals upon disconnection to prevent fluid loss or air ingress. The Neutron incorporates additional technology that will prevent fluid displacement resulting from syringe plunger compression; patient vascular pressure changes, such as coughing or sneezing; and IV solution container run-dry. The Clave Family of Connectors do not require a cap but may be used with disinfecting caps containing 70% isopropyl alcohol.

Dear Elizabeth Cozzi:
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 (the 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 available 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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Comparison Summary
Indications for Use
The intended use of the subject device and predicate device are similar. New testing also supports the additional claim that the Clave family (MicroClave™, NanoClave™, and Clave™ Neutron) prevents microbial ingress for seven days and the use with pressure infusion procedures up to 400 psi.
Principles of Operation
The subject devices principle of operation is the same as the previously cleared predicate device. Each device is a neutral displacement, normally closed, bi-directional connector with a shared self-sealing pre-slit septum. Each device incorporates an ISO 80369-7 compliant distal male luer that allows for connection to a vascular catheter or extension set. The female luer of each device is ISO 80369-7 compatible to mate with and allow access to the infusion system when activated using an ISO 80369-7 compliant male luer. When the male luer is removed from the pre-slit septum, the septum passively returns to self-seal and close the fluid path. Prior to access, disinfection of the septum is accomplished using a 70% isopropanol swab for three seconds and allow to dry, or with the application of a 70% isopropanol disinfecting cap. The subject device utilizes the same housing component and self-sealing pre-slit septum component as the predicate K100434 device. The predicate K100434 device Clave Neutron incorporates an additional design feature at the distal end of the connector to prevent fluid displacement resulting from syringe plunger rebound and patient-induced reflux. This design feature is separate from and in addition to the principles of operation which accomplish the bi-directional fluid flow and self-sealing nature of the pre-slit septum.
Intended Use
The subject devices intended use environments are the same as the previously cleared predicate and reference device. Devices are used externally to a patient as an accessory to an intravascular catheter placed in the vein or artery. The subject may be used for the administration of blood and fluids to patients. The subject device may be used for pressure infusion procedures up to 400 psi (10mL/sec), which is the same as the previously cleared predicate in K100434. The subject device has been evaluated for the prevention of microbial ingress for a worst-case simulated use protocol of seven (7) days, using Guidance for Industry and Staff: Intravascular Administration Sets Premarket Notification Submissions [510(k)], Section 8; Microbial Ingress Testing. The predicate devices evaluated microbial ingress using a three (3) day simulated use protocol. This difference in microbial ingress study duration does not raise new questions on safety and effectiveness as demonstrated by non-clinical performance testing and published clinical reports.
Technology
The subject devices have minor dimensional differences relative to the predicate that do not impact the Principles of Operation or Intended Use Environments. The difference in pressure infusion rating and microbial ingress is supported by testing in compliance with ANSI/AAMI CN 27. These differences do not raise new questions regarding safety and effectiveness of the subject devices.

Compatibility
The compatibility of the subject device and predicate device are similar. New testing supports the compatibility of the subject device with CHG based on methods described in ANSI/AAMI CN27 testing for isopropyl alcohol. Testing for compatibility with disinfectant caps is based on internal methodology.
Materials
The materials utilized in the subject device are similar to those of the predicate. The body of the subject devices has been updated to a polycarbonate material, rather than polyester as in the predicate body. The body is now made of the same material as the subject and predicate spike and base and presents no new issues of safety and effectiveness based on fully compliant ISO 10993 testing.
Summary of Non-Clinical Testing
Non-clinical verification has been conducted to evaluate the safety, performance and functionality. The results of these tests have demonstrated the overall safety of the subject device and ultimately supports a substantial equivalence determination to the predicate device. A summary of the testing conducted is presented below.
Biocompatibility Testing
Biocompatibility testing was conducted in accordance with ISO 10993-1 and FDA's September 2023 Guidance titled, "Use of International Standard ISO 10993-1, 'Biological Evaluation of Medical Devices Part 1: Evaluation and testing within a risk management process,'" as recognized by FDA. Testing included for Externally Communicating Device with Blood Path, Direct Contact, for a Prolonged Duration (>24hours to 30 days).

Particulates
Particulate contamination testing was performed by following USP to demonstrate particulate levels on the subject devices meets USP requirements.
Clinical Testing
The submission includes results of a published CMS study¹ which demonstrates a statistically significant lower relative risk of bloodstream infection and bloodstream infection-associated mortality when compared to non-Clave users in acute-care hospitals.
Conclusion
The subject device meets the functional claims and intended use as described in the product labeling. Test results from the performance testing conducted demonstrate the subject devices meet all acceptance criteria requirements. Therefore, the subject device is substantially equivalent to the predicate device cleared under K100434. The differences between the subject and predicate device do not raise any new or different questions of safety or effectiveness of the device and do not alter the intended use of the device.
