  • IK Does the plastic jacketed wire in the Introducer Kit have hydrophilic coating?

    No, the plastic jacketed wire in the Introducer Kit does not have hydrophilic coating in order to avoid the risk of guidewire slipping and falling into the blood vessel.

    GSS Can GSS be used for TFI?

    No, GSS is limited to the use in TRI. It is also written in the IFU. Please use Radifocus Introducer II for TFI.

    GSS Can GSS be used even after kinking?

    GSS is made from a soft ETFE material, which allows the sheath to come back to the original position after kinking. Therefore sheath kinking does not impair device insertion. Due to the nature of the material, there is low risk of damage to the vessel wall even after sheath is kinked.

    GSS Is there any papers on spasm?

    GSS What is the minimum radial artery diameter that each GSS size can accommodate?

    We recommend physicians to use GSS when the radial artery size is larger than the outer diameter (OD) of the sheath. The OD for each Fr size is as follows:
    5Fr GSS: 2.29mm
    6Fr GSS: 2.62mm
    7Fr GSS: 2.95mm

    History

    TIGI (4.0) design

    • First developed in Japan in 1991. (pra-no-mon shape: “Tora” means “Tiger” in Japanese)
    • The shape is combined with the concept of JL and JR, and designed one for both LCA and RCA from right radial artery.
    • The secondary curve () is for minimal injury at the aortic wall when rotating and for adjustment of back-up support when maneuvering.

    Jacky & Sarah design

    • Developed in Japan (naming after the amine-manga cartoon)
    • “Jacky” has a less acute primary curve () for better coaxial engagement with the inferior angled LCA and RCA.
    • Angled catheter tip () prevents the dislocation when flushing the catheter.

    TIG II design

    1. The proximal curve() is to locate the catheter shaft at the center of the ascending aorta to maneuver right or left easily.
    2. The primary curve () which is wider than TIG1 that fit the inferior angled LCA and RCA.
    3. Due to 1&2 above, the back-up force to LCA is little weak, that should be overcome by techniques and shapes.

    Variety of TIG Ⅱ

    Shapes What are the difference between JL/JR and CL/CR?

    CL/CR have more round curves.

    Literature Any literatures regarding Optitorque?

    Name What are SR and SAL?

  • TR Band application Can TR Band be reused?

    PRECAUTIONS
    • Do not use the TR Band Inflator for Other purposes than to inflate the TR Band. It is not designed for other
    • The TR Band can be inflated only by using the TR Band Inflator included in the kit Or the TR Band Air Volume Regulator. If other devices are used, adequate air compression can not be achieved.
    • Depending on the patient’s condition and the degree Of balloon pressure, an adverse event including artery occlusion, hypodermic hematoma, hemorrhage, pain, or numbness may occur. Check the progress of the hemostasis and adjust the air pressure accordingly.
    • When connecting the TR Band inflator included in the kit or TR Band Air Volume Regulator to the TR Band, keep the plunger in place. Releasing the plunger will cause the air to expel from the TR Band. Loss of air compression may cause bleeding.
    • Bleeding could occur if the adjustable fastener comes off during compression. Depending on the patient’s wrist size and the way the device is applied, the adjustable fastener could come off. Fix the adjustable fastener in place with tape if necessary.
    • This device has been sterilized by ethylene oxide and is for single use only. Do not resterilize or reuse.
    • Do not use this device if the unit package or the product has been damaged or soiled.
    • The device should be used immediately after the package and of safely and properly after use.
    • Avoid exposure to water, direct sunlight, extreme temperature, or high humidity during storage.

    TR Band application Is a gauze necessary between TR Band and the access site?

    No, this device is sterilized. By direct application, you can confirm the situation of hemostasis easily through the transparent material.

    TR Band application How tight should the band be fixed on the wrist?

    Fix the belt on the wrist with a little space on the ulnar artery side. It may help you to ensure enough space after air injection into the compression balloon. The space on the ulnar artery side can help avoid compression of nerves and ulnar artery, etc and thus, it can decrease pain.
    →Caution: if the band is fixed too loosely, the compression balloon may slip out from the access site or adequate pressure for hemostasis may not be achieved.
    →"Putting a 2.5mL syringe insde the band on the ulnar artery side" is an example of an easier method to fix the TR Band on the wrist.

    TR Band application What is the range of wrist size which we can apply TR Band to?

    Regular size is for 14cm-20cm wrist size and large size is for 14cm-25cm wrist size patients.
    *If you have to apply the band to patients who have thinner or thicker wrist sizes, the length of the magic tape overwrapping part will be short and the risk of coming of will be increased. So please consider countermeasures, for example, fix the adjustable fastener in place with a tape.

    TR Band application Where should we align the green marker to?

    Please align the green market on the arterial puncture site. According to the angle of insertion, there may be a gap between the skin puncture site and arterial puncture site. Where the compression pressure should be applied is the arterial puncture site.

    Compression What should we be careful of when we inject air into the compression balloon?

    After injection, quickly remove the syringe. Please make sure to keep the plunger in place with your thumb.
    →If the plunger is not kept in place, the air may be forced back into the syringe and the balloon pressure may decrease.
    →If the syringe is removed slowly, it may cause air leakage and the balloon pressure may decrease.

    PRECAUTIONS

    • Avoid exposure to water, direct sunlight, extreme temperature, or high humidity during storage.

    Compression How much is the maximum acceptable air injection volume?

    The maximum acceptable injection volume is 18ml. If this volume is exceeded, it will be painful for patients. It will also cause damage to the pressure confirmation balloon.

    Compression How long should the device be applied?

    Referring to the protocol of a hospital in Japan which uses TR Band, the standard time is 4 hours. However, compression time may differ according to the patient's condition and the hospital condition. Please check the puncture site and adjust accordingly.

    In case the patient claims pain: confirm there is no bleeding and remove an appropriate volume of air.

    In case the puncture site is bleeding:
    Inject more air until the bleeding stops. (Maximum acceptable air volume is 18ml in total.

    Recently, there is a trend to minimize the compression pressure and compression duration to order to decrease the RAO risks. Various factors such as patient's blood pressure, anticoagulation and heparin administration affect the hemostasis condition so please perform the hemostatic management carefully confirming that there is no bleeding.

    Compression How does the balloon pressure change over time?

    Please refer to the lower chart.

    Please scroll

    Compression Does the thcikness of the wrist affect the compression?

    By adjusting the band to the patient's wrist size, it is possible to compress at almost the same pressure for all patients.

    Other What does "TR Band" stand for?

    TR Band stands for "Terumo Radial Band"

    Other Why does TR Band have two balloons?

    By having two balloons, it helps direct the pressure to the puncture site. This spot compression, thanks to the combination of dual balloons and curved support plate, can avoid compression of nerves and ulnar artery, etc. This helps decrease pain.
