Instructions for use

OmniWire pressure guide wire

Caution:

• U.S. Federal Law restricts this device to sale and use by or on the order of a physician.
• Prior to use, read this entire package insert.

Indications for use:
The OmniWire pressure guide wire is indicated for use to measure pressure in coronary blood vessels during diagnostic angiography and/or any interventional procedures. It can also be used to facilitate the placement of catheters as well as other interventional devices in coronary vessels.

Description:
The OmniWire pressure guide wire (hereafter referred to as the “pressure guide wire”) is a steerable guide wire with a pressure sensor mounted 3 cm proximal to the tip. The pressure guide wire measures pressure when used with the IntraSight and Core Series of systems and is intended to be used in adult patients eligible for endovascular procedures. The pressure guide wire has a diameter of 0.014″ (0.36 mm), a length of 185 cm and is available in straight or pre-shaped tips. It is coated with hydrophilic coating (39 cm length) on the distal portion to reduce surface friction and enhance lubricity. It is also coated with a hydrophobic coating (146 cm length) on the proximal portion to reduce surface friction. The pressure guide wire is packaged attached to the connector with an OmniWire-specific torque device to facilitate navigation through the vasculature.
The clinical application of OmniWire is to acquire the raw pressure data that can be used as an input to a compatible computer-system to generate FFR-iFR indices to assess the hemodynamic significance of stenoses. E.U. and U.S. society practice guidelines for myocardial revascularization support the use of FFR/iFR measurements to guide percutaneous treatment decisions when a determination of ischemia is warranted.1,2,3,4

Contraindications :
The OmniWire pressure guide wire is not intended for use with atherectomy devices or for crossing a total vessel occlusion.

Adverse effects:
As with all catheterization procedures, complications may be encountered with the use of the pressure guide wire. The major risks of coronary angiography and coronary angioplasty include: coronary vessel dissection, occlusion, perforation, embolus, spasm, local and/or systemic infection, pneumothorax, serious arrhythmias, unplanned endovascular and/or surgical procedures, sterile inflammation or granulomas at the access site, pulmonary embolism, pulmonary infarction, myocardial embolism, myocardial infarction, embolic stroke, cerebral infarct, tissue necrosis and death. The major risks of peripheral angiography or peripheral angioplasty include: dissection, abrupt closure, perforation, embolus, spasm, unplanned endovascular and/or surgical procedures, sterile inflammation or granulomas at the access site, pulmonary embolism, pulmonary infarction, myocardial embolism, myocardial infarction, embolic stroke, cerebral infarct, tissue necrosis and death.
If a serious incident has occurred in relation to the device, it should be reported to the manufacturer and the competent authority of the Member State in which the user and/or patient is established. A serious incident means any incident that directly or indirectly led, might have led or, in case of recurrence, could lead to any of the following: the death of a patient, user or other person; the temporary or permanent serious deterioration of a patient’s, user’s, fetus or other person’s state of health, or a serious public health threat.

Warnings:

• Use of the OmniWire pressure guide wire should be restricted to specialists who are familiar with, and have been trained to perform, the procedures for which this device is intended.
• This product is supplied sterile. If the pouch is unintentionally opened before use or damaged, compromising the sterile barrier, please discard the product.
• The pressure guide wire is designed for single use only. This product cannot be re-sterilized or re-used. Re-use and/or re-sterilization of unused product may result in, but is not limited to the following risks:
  • Critical harm to patient due to device separation, material deformation or infection/sepsis;
  • Inaccurate pressure readings due to pressure sensor damage;
  • Decreased mechanical performance (including but not limited to torque ability and trackability).
• Do not use expired product. If the product is expired, discard.
• The safety and effectiveness of the device has not been established for use in the neurovascular region.
• Only use the OmniWire connector with the OmniWire pressure guide wire.
• Only use the OmniWire torque device provided with the OmniWire pressure guide wire.
• • Never advance, torque or withdraw a pressure guide wire that meets resistance.
  • This device is coated with a hydrophilic coating at the distal end of the device for a length of 39 cm, and coated with a hydrophobic coating at the proximal end of the device for a length of 146 cm. Please refer to the “Instructions for use” section for further information on how to prepare and use this device to ensure it performs as intended. Failure to abide by the warnings in this labeling might result in damage to the device coating, which may necessitate intervention or result in serious adverse events.

Precautions:

• Do not use product that has been damaged in any way as this may result in vessel damage, inaccurate pressure measurements and/or poor mechanical performance.
• In order to minimize patient risk, exercise caution when using the pressure guide wire in a stented vessel. When advancing or withdrawing the pressure guide wire in a stented vessel, in the event that the stent is not fully apposed against the vessel wall, the pressure guide wire may become entangled in one or more stent struts. This may result in entrapment of the pressure guide wire, damage to the pressure guide wire and/or stent dislocation.
• Do not wipe the distal hydrophilic coated length of the pressure guide wire with dry gauze as this may damage the device coating.
• Do not use alcohol, antiseptic solutions, or other solvents to pretreat the pressure guide wire because this may cause unpredictable changes in the coating that could affect the device safety and performance.
• The use of an anticoagulant is recommended as per the local standard angiographic protocols and at the discretion of the physician to prevent thrombus formation.
• Simultaneous use of the pressure guidewire with electrosurgery devices is not recommended.
• Do not expose the device to a magnetic resonance environment. Device may not perform as intended and may present additional risks to patient.
• The pressure guide wire performance has been confirmed with 5 French guide catheters. When using any diagnostic or guide catheters, avoid side holes and take care to flush all residual contrast to ensure a reliable iFR/FFR.

Limitations:

• The pressure guide wire is only compatible with 0.014″ (0.36 mm) ancillary devices. Instructions for use:
  • Standard workflow
    Open the pressure guide wire pouch using sterile technique and place the tray on a flat surface in the sterile field.

Warning: If any portion of the device (wire, torque device, or connector) makes contact with the non-sterile field or non-sterile personnel, discard.

• Prepare the pressure guide wire for use following the numbers on the tray:

  • Flush wire: Flush the pressure guide wire with normal sterile heparinized saline (labeled #1) using the wire flush port on the spiral dispenser.

  • Zero wire: Lift the numbered tab to remove the compartment lid (labeled #2),
    

  • Remove product from tray: Lift the numbered tab to remove the compartment lid on the tray (labeled #3). Carefully slide the connector from the tray and slide the wire out of the spiral dispenser. Place wire and connector on the sterile field.
    Precaution: When withdrawing the wire from the spiral dispenser, keep the connector and wire in the same plane to avoid kinking the wire.
    Precaution: Do not grasp the tip of the pressure guide wire to remove it from the spiral dispenser. This may result in damage to the pressure sensor.

• At the physician’s discretion, the 1 cm shapeable pressure guide wire tip may be carefully shaped using standard tip shaping practices. For best results, shape the tip in the direction of the sensor housing opening. Do not use a shaping instrument with a sharp edge. Take care when shaping the tip. Do not grip the sensor housing as this may damage the pressure sensor.

• Insert the pressure guide wire through the appropriate introducer components and guiding catheter into the desired blood vessel. Slowly advance the pressure guide wire tip under fluoroscopy using contrast injections to verify location.

• Ensure that the tip is rotating freely and no resistance is felt when torque is applied.

• In the event that resistance is felt, exercise caution when removing the device, and exchange the device for a new one to complete the procedure.
  Precaution: The pressure guide wire should not be advanced or withdrawn if resistance is encountered. The wire should never be forcibly advanced into or withdrawn from a vessel. Any time that resistance is encountered, the wire should be slowly withdrawn under fluoroscopic guidance. In some instances, the wire may kink and must be removed.

• Position the pressure sensor (located 3 cm from tip) adjacent to the tip of the guide catheter and perform normalization procedure with the instrument. For system’s operations refer to the proper system “Operator’s manual”.

• In the event the pressure guide wire is “Not Recognized”, squeeze connector and realign the pressure guide wire (see “Attaching pressure guide wire to connector” section for further instruction).

• Advance the pressure sensor to desired measurement location, making sure the sensor is distal to the stenosis, and perform pressure measurements with the instrument. Refer to “Operator’s manual” for details on how to perform pressure measurements.

• After every procedure, slowly withdraw the pressure guide wire until the pressure sensor is just distal to the guide catheter tip. Verify that the pressures measured by the pressure guide wire and through the guide catheter are equal.

• If storing the wire for subsequent measurements, place the wire underneath a drape in the sterile field. Prior to reinsertion for multiple measurements, wipe wire with normal sterile heparinized saline using damp gauze.

• When the procedure is completed, withdraw the pressure guide wire and dispose of the pressure guide wire, torque device, and connector as biohazardous waste in accordance with local regulations.

Removing pressure guide wire from connector

• The pressure guide wire may be disconnected from the connector to facilitate wire maneuverability and to allow advancement of catheters and other ancillary devices over the proximal end of the wire.
  Note: If the plug remains connected to the instrument, it is not required to repeat zeroing and normalization.

• To remove the pressure guide wire, squeeze the connector and carefully lift the proximal end of the wire from the pressure guide wire channel.

Warning: Do not flex the proximal (electrical connector) end of the pressure guide wire when not inserted in the connector. Excessive flexing can damage or break the internal components.

• If desired, loosen the torque device and withdraw it from the proximal end of the pressure guide wire.
  Precaution: When unloading the torque device, use caution to prevent coating damage.

Catheter delivery

• Thread catheter over the pressure guide wire taking care not to kink the proximal conductive bands of the wire.
  Warning: When using the pressure guide wire with ancillary devices (e.g. stenting), incorrect device advancement/withdrawal can impact the mechanical performance of the pressure guide wire, damage its coating, or result in resistance.
  Warning: Take care not to deploy any interventional device over the pressure guide wire sensor as it could result in sensor damage and inaccurate pressure measurements.
  Precaution: When loading or unloading an ancillary device over the wire, use caution to prevent coating damage.

• For catheter delivery, refer to applicable catheter device’s “Instructions for use”. Attaching pressure guide wire to connector

• Install the included torque device over the proximal end of the pressure guide wire. The connector cannot be used to effectively torque the pressure guide wire as the wire rotates freely inside the body of the connector.
  Warning: Using a torque device other than the torque device provided will damage the wire. A secondary torque device is provided in the event the primary torque device is no longer available for use (e.g. compromised sterility).
  Precaution: When reloading the torque device, use caution to prevent coating damage. Warning: The connector provided in the package is unique to the individual pressure guide wire it is connected to and should not be used with any other pressure guide wires. Use of a different connector will result in inaccurate pressure measurement data.

• Clean the proximal end of the pressure guide wire with normal sterile heparinized saline. Prior to reconnecting, dry the proximal end of the pressure guide wire with a clean, dry cloth.
  Warning: Do not flex the proximal (electrical connector) end of the pressure guide wire when not inserted in the connector. Excessive flexing can damage or break the internal components.
  Precaution: Failure to dry the proximal end of the pressure guide wire will result in inaccurate pressure measurement data.

• Squeeze the connector to expose the pressure guide wire channel.
  Hold the pressure guide wire at a slight angle to the connector and place it in the channel with approximately 0.5 inches (1.3 cm) of the pressure guide wire protruding from the connector.

• Maintaining the angle, drag the pressure guide wire through the channel until the pressure guide wire alignment notch catches the locking clip in the connector. This will align the pressure guide wire.

• Lower the pressure guide wire into the channel.

• Release the connector to lock the pressure guide wire in place

• A pressure signal will now be present on the display instrument. It is not required to repeat zeroing and normalization as long as the modular connector has not been removed from the instrument.

• In the event the pressure guide wire is “Not Recognized”, squeeze connector and realign the pressure guide wire.
