Intended Use

The QUANTIEN™ Measurement System is indicated to provide hemodynamic information for use in the diagnosis and treatment of coronary or peripheral artery disease. The QUANTIEN measurement system is intended for use in the catheterization and related cardiovascular specialty laboratories to compute, and display various physiological parameters based on the output from one or more electrodes, transducers, or measuring devices.

Device Story

Diagnostic computer system for recording, computing, displaying, and storing hemodynamic data; inputs include signals from PressureWire™ guidewires, external transducers, and ECG. System processes inputs to calculate physiological parameters: systolic/diastolic/mean blood pressure, heart rate, Fractional Flow Reserve (FFR), Resting Full-Cycle Ratio (RFR), and Pd/Pa ratio. Used in cath labs by clinicians; output displayed on screen, transferred to cath lab monitoring systems, or exported via DICOM/USB for post-procedural review on PCs. Provides real-time hemodynamic information to assist clinicians in diagnosing and treating coronary or peripheral artery disease; RFR/FFR hybrid method used to categorize ischemia-causing lesions.

Clinical Evidence

Prospective study evaluated diagnostic utility of RFR for coronary artery disease assessment. Study compared RFR-FFR hybrid approach against iFR-FFR hybrid approach. Results demonstrated comparable diagnostic accuracy (93.6% for RFR-FFR vs 92.2% for iFR-FFR), positive agreement (91.3% vs 88.8%), and negative agreement (95.8% vs 95.4%).

Technological Characteristics

Programmable diagnostic computer; backlit LCD display; inputs from PressureWire™ guidewires and external transducers; connectivity via DICOM, USB, and external server; software-based signal processing for hemodynamic parameters (FFR, RFR, Pd/Pa).

Indications for Use

Indicated for patients with coronary or peripheral artery disease requiring hemodynamic assessment in catheterization or cardiovascular specialty laboratories.

Regulatory Classification

Identification

Dear Ka Zoua Xiong:

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.

| Summary of Clinical<br>Testing | No new clinical testing was completed, nor relied upon, in support of this Traditional<br>510(k). However, a prospective study was performed to determine the diagnostic utility<br>of RFR for the physiological assessment of coronary artery disease in real world<br>patients. The results of the study showed equivalence between resting full-cycle ratio<br>(RFR) and instantaneous wave-free ratio (iFR). | |
