is inserted into the guiding catheter or guiding sheath,remove the peel-away introducer.,NOTE,:Use of a guiding catheter or a guiding sheath with a 1.91mm(0.075”)or larger,rotating,hemostasis valve is recommended when performing a procedure with the FilterWire EZ System.,The use of a sheath/guide catheter with a,fixed,hemostasis valve may cause the filter membrane to tear at the hemostasis valve upon removal.,1.Place the peel-away guide wire introducer over the tip of the delivery system(the spring tip of the system can be shaped as needed).,Peel-away Introducer Sheath,23,of 128,FilterWire EZ Embolic Protection System,Delivery(continued),3.To,advance,the FilterWire EZ System through the guiding catheter or guiding sheath,use a one-handed technique advancing both the delivery sheath and protection wire together;this will prevent accidental deployment of the filter.,4.,To,steer,the FilterWire EZ System to the target landing zone,use a two-handed technique,torquing the protection wire with one hand and advancing the delivery sheath with the other hand.,NOTE:,For carotid interventions,having the patient turn their head to the left or right will change the orientation of the vessel and may facilitate device passage.,NOTE:,Consider using the buddy wire technique if the lesion is difficult to pass.Retract the buddy wire after the lesion has been crossed by the FilterWire EZ System(If other efforts are unsuccessful,pre-dilatation can be used.),24,of 128,FilterWire EZ Embolic Protection System,Delivery(continued),5.,Advance the FilterWire EZ System across the lesion until the apex of the filter loop can be deployed a minimum of 3.0cm distal to the lesion.,NOTE:,If an interventional device with a tip-to-shoulder length of greater than 10.0mm is to be used,a longer vessel length may be required to place the FilterWire EZ System in order to avoid contact between the filters catheter stop and the tip of the interventional device.,25,of 128,Once the protection wire is in place past the lesion,slide the,torquer,tip up to the,hemostatic,valve and tighten firmly.,Deploy the filter by holding the protection wire with the,torquer,then retracting and completely removing the delivery sheath.,Be sure to keep the,torquer,in place as you peel-away the delivery sheath in a straight motion until the 3cm over-the-wire section is reached(see photo below).,FilterWire EZ Embolic Protection System,Filter Deployment,incorrect,CORRECT,Photograph taken by,Boston Scientific Corporation,26,of 128,4.Once the delivery sheath is completely removed,i,nject contrast and verify the device is in the proper position and there is adequate flow.,NOTE:,If repositioning is required,the EZ Retrieval Sheath should be used.Retract the protection wire and filter loop into the sheath,reposition the filter and redeploy.,5.,Use the protection wire like a traditional guide wire to track catheters and stent delivery systems to the target treatment area.,FilterWire EZ Embolic Protection System,Filter Deployment(continued),27,of 128,1.Inject contrast frequently and always after any intervention or exchange,to visually verify that blood flow is not obstructed and that filter loop/vessel apposition to the vessel wall is maintained.,CAUTION:,If a filter becomes occluded during the procedure,remove it and deploy a second filter if further intervention is required.,2.Complete the procedure making sure the protection wire remains in the proper position distal to the lesion(monitor fluoroscopy).,Note:,Failure to stabilize the protection wire could lead to inadvertent movement of the filter,resulting in protection wire entanglement and/or delay in the procedure.,FilterWire EZ Embolic Protection System,During the Procedure,28,of 128,FilterWire EZ Embolic Protection System,Filter Capture and Retrieval,1.Remove the EZ Retrieval Sheath from its packaging coil and flush with heparinized saline.,2.Advance the retrieval sheath over the protection wire past any deployed stents up to the proximal end of the filter loop.,Note:,If the EZ Retrieval Sheath is not able to pass the deployed stent,be sure the stent is well apposed and consider post-dilitation.If the Retrieval Sheath is still unable to cross,try the EZ Bent Tip Retrieval Sheath(available separately).,EZ Bent Tip Retrieval Sheath Packaging,29,of 128,FilterWire EZ Embolic Protection System,Filter Capture and Retrieval(continued),3.Gently and slowly retract the protection wire and filter loop back into the retrieval sheath until resistance is felt.,4.Observe the retrieval procedure under fluoroscopic imaging.,Note:,The distal edge of the collapsed filter loop should,align with,(see figure B),or be,proximal to,(figure A),the retrieval sheath marker band.,Retrieval Sheath Marker Band,A,B,30,of 128,FilterWire EZ Embolic Protection System,Filter Capture and Retrieval(continued),NOTE:,If resistance is felt before the distal edge of the collapsed filter loop is aligned with the marker band,it is possible that there is a large amount of embolic debris in the filter.Carefully retract the protection wire and EZ Retrieval Sheath as a system.The distal part of the filter bag will be outside of the sheath during retrieval in this case;however,the filter loop must be pulled fully into the sheath.,Fully Retracted Filter,Large Debris Load in Filter,31,of 128,FilterWire EZ Embolic Protection System,Filter Capture and Retrieval(continued),5.If any resistance is met during retraction of the sheathed FilterWire EZ System,slightly advance the sheathed FilterWire EZ System and rotate the sheath before continuing to retract.,6.Slowly and carefully retract the entire system until the tip of the retrieval sheath is adjacent to the tip of the guiding catheter or guiding sheath.,7.If there is any resistance,retract the guiding catheter and FilterWire EZ System together.This is done in case there is a large amount of embolic material captured in the filter that may not fit inside the guiding catheter.,32,of 128,FilterWire EZ Embolic Protection System,Filter Capture and Retrieval(continued),8.Remove the FilterWire EZ System from the patient.,NOTEWhen using a,rotating hemostasis valve,ensure that the hemostasis valve is fully opened prior to FilterWire EZ System removal.,CAUTION:,If a guide sheath with a fixed hemostasis valve is used,the valve dilator tool is required for FilterWire EZ System removal.Removing the FilterWire EZ System through a fixed hemostasis valve without the use of a valve dilator may cause the filter membrane to tear.,9.If a fixed hemostasis valve is used,place the valve dilator(if provided in the accessory kit)on the shaft of the retrieval sheath and slide the tool into the valve.Then remove the FilterWire EZ System from the patient through the valve dilator tool and remove the dilator.,33,of 128,Stent Entanglement,Potential for a distal embolic protection filter to entangle with a stent is inherent to interventional procedures using these devices.,SAFE PRACTICE FOR DISTAL PROTECTION FILTERS:,Achieve good guide catheter or guide sheath support,Ensure sufficient landing zone,Keep the filter in place during deployment,Minimize wire movement during the procedure,Achieve full stent apposition,34,of 128,FilterWire EZ Embolic Protection System,Tips for Use,Key Success Factors for Using the FilterWire EZ
