DEVICE DESCRIPTION The scoreflex Coronary Dilatation Catheter is designed for easy guidewire exchange. Balloon diameter is 2.0, 2.5, 3.0, 3.5 and 4.0mm, and the length is 10, 15 and 20 mm. The balloon material is made of a semi-compliant nylon material with a rated burst pressure of 16 atmospheres. The proximal shaft of the catheter is composed of a female luer connector bonded to a Pebax tube jacketed on stainless steel tube. The proximal shaft joins with a smooth transition to a distal shaft composed of an outer tube of nylon with a balloon, tip tubes and pulling wire welded at the distal tip, the pulling wire is laser welded to the stainless steel tube skive. The distal outer body distal end is welded to the balloon proximal leg and the pulling wire. The pulling wire cutting section is outside of the balloon. Two radiopaque platinum/iridium marker bands are aligned with the balloon shoulders. The lumen tip section of the catheter accepts a standard 0.014 inch PTCA guidewire. The guidewire enters the catheter tip and advances coaxially out the tip Rx port, thereby allowing both coaxial guidance and rapid exchange of catheter with a single standard length guidewire. Two marked sections, 3mm in length, are located on the proximal shaft indicating the catheter position relative to the tip of either a brachial or femoral guiding catheter. The design of this dilatation catheter does not incorporate a lumen for distal dye injections or distal pressure measurements. The catheter is lubricated with hydrophilic coating on the tip and the distal outer body surface, the tip inner lumen and the balloon are lubricated with silicone coating.

PREPARATION FOR USE Prior to use, examine all equipment carefully for defects. Examine the dilatation cathe ter for bends, kinks, or other damage. Do not use any defective equipment. Prepare equipment to be used following manufacturer’s instructions or standard procedure. Complete the following steps to prepare the PTCA catheter for use: 1. slide the protective sheath off the balloon. 2. Remove the protective mandrel from the catheter tip. 3. Prepareaninflationdevicewiththerecommendedcontrastmedium
according to the manufacturer’s instructions. 4. Gentlyflushtheguidewirelumenwithsterile,heparinizedsaline
solution (the solution will exit at the distal end of the balloon). 5. Evacuate air from the balloon segment using the following
procedure: 6. Filla20ccsyringeortheinflationdevicewithapproximately4ccof
the recommended contrast medium. 7. Afterattachingthesyringeorinflationdevicetotheballooninflation

8. Applynegativepressureandaspiratefor15seconds.Slowlyreleasethepressuretoneutral,allowingcontrasttofilltheshaftofthedilatation catheter.
9. Disconnectthesyringeorinflationdevicefromtheinflationportofthe dilatation catheter.
10.Removeallairfromthesyringeorinflationdevicebarrel.Reconnectthesyringeorinflationdevicetotheinflationportofthedilatationcatheter. Maintain negative pressure on the balloon until air no longer returns to the device.
11. slowly release the device pressure to neutral. 12.Disconnectthe20ccsyringe(ifused)andconnecttheinflation

Caution: All air must be removed from the balloon and displaced with contrast prior to inserting into the body. Otherwise complications may occur.
INSTRUCTIONS FOR USE 1. Insert a guidewire through the hemostatic valve that is on the
guiding catheter, following the manufacturer’s instructions. 2. Advance the guidewire carefully into and through the guiding
catheter. Withdraw the guidewire introducer, if used. 3. Attach a torque device to the guidewire, if desired. under
fluoroscopy,proceedwithacceptedPTCAtechniquestoadvancetheguidewire to and across the lesion.
4. Backload the distal tip of the dilatation catheter onto the guidewire ensuring that guidewire exits the notch located distal to the balloon.
Note: When backloading the catheter onto the guidewire, the catheter should be supported, ensuring that the guidewire does not wrap around the balloon.5. Advance the dilatation catheter over the guidewire until it
approaches the hemostatic valve. 6. Open the hemostatic valve. Insert the dilatation catheter while
maintaining guidewire position and tighten the hemostatic valve. Tofacilitateinsertion,theballoonmustbefullydeflatedtonegativepressure.
7. Tighten the hemostatic valve to create a seal around the dilatation catheter without inhibiting movement of the dilatation catheter. This will allow continuous recording of proximal coronary artery pressure.
Note: It is important that the hemostatic valve be closed tightly enough to prevent blood leakage around the dilatation catheter shaft, yetnotsotightthatitrestrictstheflowofcontrastintoandoutoftheballoon or restricts guidewire movement. 8. Advancethedilatationcatheteruntiltheappropriateproximal
marker aligns with the hemostatic valve hub. This indicates that the dilatation catheter tip has reached the guiding catheter tip.
9. Advance the dilatation catheter over the guidewire and into the stenosis.Continueunderfluoroscopyandusetheradiopaquemarker band(s) to position the usable (dilating) section of the balloon within the stenosis.
10.Itisrecommendedthattheballooninflationprotocolinthissectionis followed. However, at the discretion of the physician, an alternate inflationtechniquemaybeemployed:a. Begininflationat2atm(or203kPa)andholdatthispressure
for 10-20 seconds. b. Increasetheinflationpressureatarateof1atmevery
10-20 seconds until the indentation in the balloon disappears. Hold at this pressure for 10 seconds.
c. Aftertheindentationhasdisappeared,increasetheinflationpressure at a rate of 1 atm (101 kPa) every 10 seconds until the targetballoondiameterisachievedbyfluoroscopicassessment.Holdatthefinal(maximum)pressurefor20seconds.
d. Ifthecontinousballooninflationintheabovestepsresultsinpatient discomfort or sT segment changes, the physician may modifytheinflationprotocolasfollows:• Deflatetheballoonandallowtheischemiatoresolve• Resumetheinflationprotocol,startingatthehighestpressure
achievedduringthepreviousinflation.Inflatetheballoonfrom zero to the new pressure using an incremental increase in pressure.
e. Afterthetargetballoondiameterisachieved,additionalinflationsmay be performed at the discretion of the physician. Maintain negativepressureontheballoonbetweeninflations.
11. To remove the dilatation catheter, apply negative pressure using the inflationdeviceandconfirmthattheballoonisfullydeflated.
12.Withdrawthedeflateddilatationcatheterthroughthehemostaticvalve. If insertion of another catheter is desired, the guidewire may be kept in place.
13. Reseal the hemostatic valve per its instructions for use.14. The catheter may be coiled once using the securement clip provided
in the package (attached to the bottom left of the compliance card). Care should be taken not to kink or bend the shaft upon placement or removal of the securement clip. Only the proximal shaft should besecuredwiththesecurementclip;itisnotintendedforthedistalend of the catheter.
15. The balloon may be re-folded once (after expansion) using the balloon re-wrap tool provided in the package (attached to the upper right of the compliance card). Care should be taken not to damage the balloon upon placement or removal of the re-wrap tool.
EXCHANGE PROCEDURE TECHNIQUE ThePTCAcatheterhasbeenspecificallydesignedforrapid,singleoperator balloon exchanges. To perform a dilatation catheter exchange: 1. Loosen the hemostatic valve. 2. Hold the guidewire and hemostatic valve in one hand, while
grasping the balloon shaft in the other hand.
3. Maintain guidewire position in the coronary artery by holding the wire stationary, and begin pulling the dilatation catheter out of the guiding catheterwhilemonitoringthewirepositionunderfluoroscopy.
4. Withdrawthedeflateddilatationcatheteruntiltheguidewirelumenisreached.Carefullypullbacktheflexible,distalportionofthedilatationcatheter out of the rotating hemostatic valve while maintaining the guidewire’s position across the lesion.
Note: If resistance is felt, remove PTCA catheter, guidewire and guiding catheter together from the vasculature. 5. slide the distal tip of the dilatation catheter out of the hemostatic
valve, and tighten valve onto the guidewire to hold it securely in place. 6. Prepare the next dilatation catheter to be used, as previously
described in the Preparation for use section. 7. Backload another dilatation catheter onto the guidewire as previously
described under the Instructions for use section, step 4, and continue the procedure accordingly.
