Description
The FLOW COUPLER System consists of a FLOW COUPLER Device and a FLOW COUPLER Monitor. The FLOW COUPLER Monitor is a pulsed Doppler ultrasound system designed for the detection of blood flow in vessels. The FLOW COUPLER Device includes a 20MHz ultrasonic Doppler transducer (probe) attached to one of the FLOW COUPLER rings, and an external lead. The probe connects to the monitor via the external lead and emits a pulsed ultrasonic signal. An audible signal of varying volume strength is produced when the probe detects flow.
Indications For Use:
The FLOW COUPLER Device is a single use, implantable device that is intended to be used in the end-to-end anastomosis of vein and arteries normally encountered in microsurgical and vascular reconstructive procedures. The FLOW COUPLER Device includes a pair of permanently implanted rings which secure the anastomosis and a removable Doppler probe that is press-fit onto one of the rings. When the FLOW COUPLER Device is used in conjunction with the FLOW COUPLER Monitor, the FLOW COUPLER System is intended to detect blood flow and confirm vessel patency intra-operatively and post-operatively at the anastomotic site. Post-operatively, blood flow can be detected on an as-needed basis for up to 7 days. The FLOW COUPLER Doppler probe is not intended to be a permanent implant and should be removed 3 to 14 days post-operatively.
Contraindications:
The FLOW COUPLER Monitor is not intended specifically to diagnose, monitor or correct a defect of the heart or the central circulatory system.
Warnings:
CAUTIONS:
• If procedures are not followed, possible equipment or software damage may occur. • The FLOW COUPLER System may be susceptible to picking up interference through the coaxial cable that connects the probe to the Monitor. Do not use in the presence of any high frequency equipment, including high frequency surgical generators. • The FLOW COUPLER Monitor may turn off or lose LCD touch screen function due to electrostatic discharge interference. Turn on the monitor and monitor’s function to generate audible sounds and hardware control using buttons should not be impacted. • Only use Monitor with FLOW COUPLER devices. • Only use FLOW COUPLER AC Power Supply included with the COUPLER Monitor (GEM1020M-2) or Power Supply sold separately (GEM1020PS-2). • Monitor and power supply may be returned to manufacturer for proper disposal. • During the use of all ultrasound devices, the operator should minimize the exposure of ultrasound energy to the patient using the principle of ALARA (As Low As Reasonably Achievable). • No modification of this equipment is allowed. • The FLOW COUPLER Monitor is intended for use by healthcare professionals only. • The FLOW COUPLER Monitor and System may cause radio interference or may disrupt the operation of nearby equipment. • Protected Health Information (PHI) or Personally Identifiable Information (PII) shall not be used as File ID or Facility ID.
• If procedures are not followed, injury may occur. • Do not perform servicing and maintenance while the monitor is in use. • Never sterilize the FLOW COUPLER Monitor with autoclave, ultraviolet, gamma radiation, gas, steam, or heat sterilization techniques. Severe device damage and/or injury may occur. • The Monitor should not contact mucus membranes, blood, or compromised tissue, and is not used in sterile fields. • Not for use in OXYGEN ENRICHED atmospheres. • Do not remove internal rechargeable lithium ion battery pack. If required, return the monitor to the manufacturer for the battery replacement. • Monitor not suitable for use in the presence of a flammable anesthetic mixture with air or with oxygen or nitrous oxide.

Carefully unpack your FLOW COUPLER Monitor. Inspect the monitor for damage. If the monitor is damaged, contact the manufacturer for further instructions. Place the Monitor on a suitable stand, cart or table outside the sterile field, near the physician who will be using the FLOW COUPLER System. Avoid using the Monitor in the presence of any high frequency equipment, including high frequency surgical generators. The Monitor has a rating of IPX-0. Keep the Monitor away from all open liquids. NOTE: If the external lead is near electrically active conductors, such as electro-surgery cables or an electronic equipment chassis, signals from the cables or chassis may be picked up by the Monitor and produce undesired audible signals. This interference is easily distinguished from blood flow and is remedied by moving the external lead away from the source of the interference. Connect the Power Supply provided with the monitor or sold separately (GEM1020PS-2) to the Monitor, if desired. Connect the Power Supply to the appropriate adaptor plugs supplied with the Power Supply. Connect the adaptor plug to a grounded hospital grade outlet. The monitor contains internally rechargeable batteries. If charged, the Power Supply is not required for the operation of the monitor. NOTE: Patient isolation from the AC power is accomplished in the following ways: The DC power output lines from the power supply are isolated from the mains in the DC power supply. There is no connection between the “green” safety ground and the Monitor. The
final isolation mechanism is the cable insulation and potting of the probe that provides an additional insulation layer between the isolated electrical signals and the patient. 4. Turn the Monitor on by depressing the Power Button located on the back of the monitor. 5. Enter Audio ID and Facility ID. Do not use PII or PHI for IDs. NOTE: Use instructions for the remote monitoring via APP are included in the User Manual supplied with the Monitor. 6. Check for the battery level shown in upper right portion of the LCD screen. Connect the Power Supply to the monitor as instructed in Step 3, if desired. 7. Refer to FLOW COUPLER Device and System Instructions for Use for handling of the FLOW COUPLER Device. NOTE: Probe leads may be labeled with the Channel A or B for identification. 8. Transfer the free connector of the external lead (supplied with the FLOW COUPLER device) outside the sterile field. Insert this free connector into either Channel receptacle A or Channel receptacle B on the front side of the Monitor. 9. Ensure that correct Channel Selection Button is illuminated and Channel Selection Indicator on the LCD screen is displayed. 10. Listen for blood flow. Some background noise may be audible. NOTE: If blood flow is not detected with the Monitor post-operatively, rely on clinical indications for patient status. 11. Adjust the volume by depressing and holding the Volume Increase Button or Volume Decrease Button to the desired level. If a strong audible signal is not identified, irrigate the anastomotic site with saline and inspect the probe is in contact with the vessel. During irrigation, an audible signal from the Monitor verifies proper function of the device. 12. Turn off the Monitor after use by depressing the Power Button.
6.
Special instructions: Maintenance and Cleaning: The Monitor requires minimal maintenance. Keep it clean and free of dust. The exterior may be cleaned using the following steps: 1. After every use, check the Monitor for any sign of damage or wear. 2. Wipe the Monitor with a dry or water-moistened soft cloth. Ensure any residual organic material is removed. Do not pour or spray liquid directly on the Monitor. Allow to air dry before use. 3. Do not put liquid near the speaker.
