• IMPORTANT INFORMATION: These materials are intended to describe common clinical considerations and procedural steps for the on-label use of referenced technologies as well as current standards of care for certain conditions. Of course, patients and their medical circumstances vary, so the clinical considerations and procedural steps described may not be appropriate for every patient or case. As always, decisions surrounding patient care depend on the physician’s professional judgment in light of all available information for the case at hand.

• Boston Scientific (BSC) does not promote or encourage the use of its devices outside their approved labeling.

• The presenter’s experience with BSC products may not be interpreted or relied upon to support clinical claims about BSC devices or product comparison claims regarding BSC and competitive devices. The experiences of other users may vary.

Page 23: Clearing a Path for the Effective Treatment of …...The law restricts these devices to sale by or on the order of a physician. Indications, contraindications, Indications, contraindications,

• Mechanical removal of thrombus, or • Combination of chemical and mechanical thrombolysis

– Power Pulse Delivery enables infusion of physician-specified fluids directly into the thrombus

• Saline jets create a low pressure zone around the catheter tip that causes

a vacuum effect • Thrombus is drawn into the catheter, where it is fragmented by the jets

and then removed from the body

• Peripheral indications include breaking up and removing thrombus from:

AngioJetTM Thrombectomy Systems

– Infrainguinal peripheral arteries, upper and lower extremity peripheral arteries

– Upper extremity peripheral veins, ileofemoral and lower extremity veins

JETSTREAMTM Atherectomy Systems Caution: Federal (US) law restricts this device to sale by or on the order of a physician. The JETSTREAM System is intended for use in atherectomy of the peripheral vasculature and to break apart and remove thrombus from upper and lower extremity peripheral arteries. It is not intended for use in coronary, carotid, iliac or renal vasculature. See product Information for Use for specific and complete prescribing information. Indications, operating specifications and availability may vary by country. Check with local product representation and country-specific Information For Use for your country. JetStreamTM atherectomy system is manufactured and distributed in EU by Bayer Healthcare. AngioJetTM Thrombectomy Systems for Peripheral Use General Indications/Contraindications AngioJet System peripheral indications include: breaking up and removing thrombus from infra-inguinal peripheral arteries, upper and lower extremity peripheral arteries, upper extremity peripheral veins, ileofemoral, infra-iliac and lower extremity veins, A-V access conduits, and for use with the AngioJet Power Pulse Kit for the control and selective infusion of physician specified fluids, including thrombolytic agents, into the peripheral vascular system. AngioJet System coronary indications include: removing thrombus in the treatment of patients with symptomatic coronary artery or saphenous vein graft lesions prior to balloon angioplasty or stent placement. Do not use in patients: who are contraindicated for intracoronary or endovascular procedures, who cannot tolerate contrast media, and in whom the lesion cannot be accessed with the wire guide. General Warnings and Precautions The System has not been evaluated for treatment of pulmonary embolism in the US and some other countries or for use in the carotid or cerebral vasculature. Some AngioJet devices have not been evaluated for use in coronary vasculature. Operation of the catheter may cause embolization of some thrombus and/or thrombotic particulate debris. Cardiac arrhythmias may occur and cardiac rhythm should be monitored during catheter use and appropriate management employed, if needed. Systemic heparinization is advisable to avoid pericatheterization thrombus and acute rethrombosis. Operation of the System causes transient hemolysis. Large thrombus burdens may result in significant hemoglobinemia which should be monitored. Consider hydration, as appropriate. Before coronary AngioJet treatment, verify the presence of thrombus because routine use of AngioJet in every STEMI patient, without proper selection for thrombus, has been associated with increased mortality risk. Do not use the system in the coronary vasculature without placing a temporary pacing catheter to support the patient through hemodynamically significant arrhythmias which may occur. Potential Adverse Events Potential adverse events (in alphabetical order) which may be associated with use of the system are similar to those associated with other interventional procedures and include but are not limited to the following: abrupt closure of treated vessel, acute myocardial infarction, acute renal failure, arrhythmias (including VF and VT), bleeding from access site, death, dissection, embolization (proximal or distal), emergent CABG, hematoma, hemolysis, hemorrhage requiring transfusion, hypotension/hypertension, infection at access site, myocardial ischemia, pain, pancreatitis, perforation, pseudoaneurysm, reactions to contrast medium, stroke/CVA, thrombosis/occlusion, total occlusion of treated vessel, vascular aneurysm, vascular spasm, vessel wall or valve damage. CAUTION: Federal (USA) Law restricts the device to sale by or on the order of a physician.

Take-Home Messages • Recognition of the utility of atherectomy and thrombectomy and their

potential role in enhancing the efficacy of drug-eluting technologies is growing

• In addition to use as primary therapy, atherectomy and thrombectomy facilitate the use of other therapies (eg, atherectomy for calcium removal, promote drug-eluting therapy efficacy)

• Clinical data suggest that treatment with the JetstreamTM Atherectomy System improves stenosis severity, even with severe calcification

• The combination of mechanical thrombectomy and chemical thrombolysis offered by the AngioJetTM Thrombectomy System enables potential benefits such as: thrombus removal in a single procedure, decreased dose and duration of lytic, and decreased bleeding complications

• Proactive venous thrombectomy improves post-thrombotic morbidity
