• Record ID: K142598
• Device Name: Opto Wire and OptoMonitor System
• Applicant: Opsens, Inc.
• Product Code: DQX · Cardiovascular
• Decision Date: Jun 12, 2015
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 870.1330
• Device Class: Class 2

Intended Use

To measure pressure in blood vessels including both coronary and peripheral vessels, during diagnostic angiography and/ or other any interventional procedures. Blood pressure measurements provide hemodynamic information, such as fractional flow reserve, for the diagnosis and treatment of blood vessel disease.

Device Story

OptoWire and OptoMonitor System measures intravascular blood pressure and fractional flow reserve (FFR). System comprises sterile, single-use fiberoptic pressure-sensing guidewire (OptoWire) and reusable electronic signal processing/display unit (OptoMonitor). Used in clinical settings (e.g., cath lab) by physicians during angiography/interventional procedures. OptoWire transmits pressure signals via fiber optics to OptoMonitor; monitor processes signals to display real-time pressure curves and numerical values (mean aortic/distal pressure, Pd/Pa ratio). Physician uses output to assess hemodynamic significance of vessel lesions, guiding treatment decisions. Benefits include accurate, real-time physiological assessment of blood vessel disease.

Clinical Evidence

No clinical data. Evidence consists of bench testing (mechanical, functional, electrical safety per IEC 60601-1, EMC per IEC 60601-1-2) and animal studies characterizing in-vivo handling, compatibility, and pressure measurement accuracy compared to predicate devices.

Technological Characteristics

Guidewire: 0.014" diameter, stainless steel/nitinol shaft, Teflon/silicone coating, fiberoptic pressure sensor. Monitor: LCD touchscreen, electrical isolation (Class 2), operating range 70-106 kPa, pressure range -30 to 300 mmHg. Connectivity: fiberoptic sensor to monitor. Sterilization: Ethylene oxide (ISO 11135-1). Software: IEC 62304 compliant.

Indications for Use

Indicated for patients requiring intravascular pressure measurement in coronary or peripheral blood vessels during diagnostic angiography or interventional procedures to obtain hemodynamic information, such as fractional flow reserve, for diagnosis and treatment of blood vessel disease.

Regulatory Classification

Identification

A catheter guide wire is a coiled wire that is designed to fit inside a percutaneous catheter for the purpose of directing the catheter through a blood vessel.

Special Controls

*Classification.* Class II (special controls). The device, when it is a torque device that is manually operated, non-patient contacting, and intended to manipulate non-cerebral vascular guide wires, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

measurements provide hemodynamic information, such as fractional flow reserve, for the diagnosis and treatment of blood vessel disease.

## Device Description:

The OptoWire and OptoMonitor System includes a pressure sensing guidewire (OptoWire), electronic signal processing and display units (OptoMonitor) that process signals received from the OptoWire to display intravascular blood pressure and fractional flow reserve (FFR) values, and various connection cables. The OptoWire and OptoWire cable are sterile, single-use devices; the remaining system components are reusable.

## Substantial Equivalence:

The OptoWire and OptoMonitor System is substantially equivalent to the Volcano Corp. PrimeWire Prestige Plus Pressure Sensing Guidewire (K111395) and the Volcano Corp. ComboMap Pressure and Flow System (K041134). Substantial equivalence is based on indications for use, technological characteristics, device materials, performance characteristics; physical and functional test results, and conformity with standards. A substantial equivalence summary table is provided at the end of this 510(k) Summary.

## Biocompatibility Testing:

Testing has been performed on the OptoWire device in accordance with the ISO 10993 family of standards to confirm that all patient-contacting materials are biocompatible. This testing included cytotoxicity, intracutaneous toxicity, acute systemic toxicity, sensitization, hemocompatibility and pyrogenicity.

#### Sterilization, Packaging and Shelf Llife:

The OptoWire is sterilized to a 106 SAL using an ethylene oxide process that has been validated in accordance with ISO 11135-1. The remaining system components are non-sterile. Testing has been performed to confirm that all packaging (sterile barrier and outer packaging) meets predetermined acceptance criteria with respect to sterile package seal strength and seal integrity, and that the packaging adequately protects all system components throughout transportation and storage. The sterile product shelf life has been validated through package and product testing of unaged devices as well as devices that have been held at an elevated temperature to simulate the labelled shelf life. Samples will also be tested after real time aging.

#### Software:

The OptoMonitor contains software that has been developed, documented and validated in accordance with industry standards (IEC 62304 - Medical device software - Software life cycle processes) and FDA guidance (General Principles of Software Validation; Final Guidance for FDA and Industry). Complete software design, risk and validation documents have been provided in accordance with FDA's Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices. Software validation has demonstrated that the system software operates in accordance with design specifications and the system operates as intended when used for its intended use.
