The PM2™ System with ECGuide™ Connector is indicated for the positioning of central venous access devices (CVADs) of at least 1Fr in size. It provides catheter tip location information by using the patient's cardiac electrical activity. The PM2™ System with ECGuide™ Connector is indicated for use as an alternative method to chest x-ray or fluoroscopy for confirmation of all central venous access devices.
In adult patients and in adolescents (greater than 12 through 21 years of age), The ECGuide™ can be used with CVADs such as peripherally inserted central catheters (PICCs), centrally inserted central catheters (CICCs), implantable ports, and hemodialysis catheters; in children (greater than 2 to 12 years of age), ECGuide™ can be used with PICCs and with CICCs; in infants (greater than 1 month to 2 years of age) and in neonates (from birth to 1 month of age), ECGuide™ Can be used with PICCs and CICCs. In each specific age group, the CVAD type and size must be chosen and the CVAD must be used according to the CVAD's indications and instructions for use.
Note: In general, devices that utilize ECG technique to observe P-wave are limited, but not contraindicated, for patients where cardiac rhythms may change presentation of the P-wave; including
- Atrial fibrillation
- Atrial flutter
- Severe tachycardia
- Pacemaker-driven rhythm
- Chronic obstructive pulmonary disease (COPD)
Such patients are easily identified prior to central catheter insertion. In these specific cases, use of an additional confirmation method is necessary to confirm catheter tip location.
The purpose of this Special 510(k) is for the expansion of indications for use of the previously cleared PM2™ System with ECGuide™ Connector (K240486) from use in adults to pediatric populations. There have been no major changes to the device since initial clearance under K240486. The PM2™ System with ECGuide™ Connector is a device used by clinicians for bedside tip location confirmation of central venous catheters. The PM2™ System with ECGuide™ Connector provide real-time catheter tip location information by using intravascular ECG (ivECG). The ECGuide™ Connector is connected to the distal lumen hub of a CVC and primed with saline to create an ivECG electrode at the distal tip of the catheter and allow for ECG catheter tip confirmation. The ECGuide™ Connector is used only during CVC installation, and removed once the CVC tip position is confirmed to be at the target location. The ECGuide™ Connector is electrically connected to the PM2 system which processes, displays, and stores the ECG waveforms.

DEVICE DESCRIPTION
The purpose of this Special 510(k) is for the expansion of indications for use of the previously cleared PM2™ System with ECGuide™ Connector (K240486) from use in adults to pediatric populations. There have been no major changes to the device since initial clearance under K240486. The PM2™ System with ECGuide™ Connector is a device used by clinicians for bedside tip location confirmation of central venous catheters. The PM2™ System with

Such patients are easily identified prior to central catheter insertion. In these specific cases, use of an additional confirmation method is necessary to confirm catheter tip location.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS
The subject device and the predicate Neonav device have the same technological characteristics for providing intravascular ECG to the end user to facilitate catheter tip confirmation. Both devices utilize a luer-lock style connector to connect to a CVC and a saline column within the lumen of the CVC to conduct the intravascular ECG signal to the tip. Furthermore, the subject device is identical to the predicate PM2™ System with ECGuide™ Connector (K240486). The technological differences between the PM2™ System and ECGuide™ Connector and the Neonav device do not raise different questions of safety and effectiveness. Both devices use
Page 7
ECG for catheter tip location information. The safety of these approaches have been well established and determined to be acceptable in multiple FDA cleared devices with the same intended uses.
SUMMARY OF NON-CLINICAL TESTING
Various non-clinical tests were previously completed on the PM2™ System with ECGuide™ Connector under the K240486 submission. This testing included, but was not limited to: electrical safety, EMC, software verification and validation, cybersecurity testing, tensile strength, insertion force, corrosion resistance, catheter compatibility, leak testing, electrical hardware verification, sterile barrier packaging testing, biocompatibility, design validation, and human factors validation. This testing was not repeated in this submission as the device design has not changed.
However, additional bench testing was performed to demonstrate that Neonav is able to capture data from lines down to 1Fr. Test methods similar to that of the predicate Neonav device were used to assess this. Furthermore, a clinical literature analysis was done to support the safety and effectiveness of PICCs in adolescents, children, infants, and neonates. No clinical testing was provided to support substantial equivalence.
All tests were performed objectively following Piccolo Medical's Quality Management System using pre-approved test protocols and post-test approval of applicable test reports. Where appropriate, Piccolo Medical employed the use of FDA consensus standards and FDA guidance during each test therefore the test methods were concluded to be acceptable.
The subject PM2™ System with ECGuide™ Connector has the same intended use and fundamental technology as its legally marketed predicate devices. The performance summary and analyses included in this premarket notification support a determination of substantial equivalence.
CONCLUSION
The PM2™ System with ECGuide™ Connector is considered substantially equivalent to the predicate devices based on the testing performed, the identical indications for use, and similar technological characteristics.
