Ostil Pro Stent Positioning System The Chllenge of Stenting Aorto-Ostil Lesions Aorto-ostil (AO) stenting ccounts for n estimted 5%-7% of coronry interventions 1 nd more thn 90% of renl rtery interventions. 9 AO lesions re more likely to be ssocited with suboptiml ngiogrphic results due to lesion rigidity nd elstic recoil 4, nd hve higher rtes of trget lesion revsculriztion. 5 Conventionl ngiogrphic lndmrks used during stenting of AO lesions re often mbiguous nd/or misleding, mking ccurte stent positioning extremely difficult. 7 In retrospective study of 100 ptients in whom stents were plced using ngiogrphic lndmrks, correct stent positioning ws chieved in only 46% of cses. 9 This device ws ssocited with decresed procedure time, rdition exposure nd reduced use of contrst. 1 Stent Positioning t Aorto-Ostil Sites Stent too distl Stent position correct Stent too proximl Incomplete coverge of the lesion Protrusion my prevent reenggement of vessel ort

Essentil Prescribing Informtion OSTIAL PRO Stent Positioning System Indictions For Use The OSTIAL PRO Stent Positioning System is intended for use in ort-ostil procedures to introduce nd position stents nd other interventionl devices within the coronry nd peripherl vsculture. In ddition, the OSTIAL PRO Stent Positioning System is intended to fcilitte the lignment of interventionl devices nd function s n lignment tool. Contrindictions If other interventionl devices re used in conjunction with the OSTIAL PRO Stent Positioning System, refer to specific mnufcturer s product lbeling for intended use, contrindictions nd potentil complictions ssocited with tht device. Wrnings nd Precutions For Single Use Only. Do Not Resterilize. Device is sterile if the pckge is dry, unopened nd undmged. Do not use if the pckge sel is broken. The device must be used prior to the expirtion dte. Discrd device if mishndling hs cused possible dmge or contmintion. It is recommended tht the ptient must hve received therpeutic dosge of Heprin to chieve ACT > 200. If extended procedure is required (greter thn 30 minutes), it is recommended to not lod the OSTIAL PRO Stent Positioning System into the guiding ctheter until it is needed to id in the plcement of the stent. For these procedures, utilize the Front Loding steps for the OSTIAL PRO Stent Positioning System introduction into the guiding ctheter. If the OSTIAL PRO Stent Positioning System feet nd cylinder is dvnced out of the distl end of the guiding ctheter, gently pull on the proximl end of the OSTIAL PRO Stent Positioning System until the cylinder hs retrcted into the distl end of the guiding ctheter leving only the gold-plted feet exposed or retrct both components in the distl end of the guiding ctheter. Never pull bck the OSTIAL PRO Stent Positioning System with gret force. In the event the cylinder nd feet of the OSTIAL PRO Stent Positioning System re dvnced too fr distlly from the tip of the guide cusing the OSTIAL PRO Stent Positioning System to become deriled from the stent delivery system, perform the following steps: Retrct stent delivery system into guiding ctheter. Never retrct OSTIAL PRO Stent Positioning System into guiding ctheter before stent delivery system hs been withdrwn. Retrct OSTIAL PRO Stent Positioning System into guiding ctheter until feet collpse. Re-cross ostil lesion with stent delivery system. Advnce OSTIAL PRO Stent Positioning System until feet pop out. Stent crossing profile must be less thn Ostil Pro Stent Positioning System effective ID to prevent stent or Ostil Pro Stent Positioning System dmge.
