The Proxis System is indicated for use as a proximal embolic protection system to prevent distal release of and to aspirate embolic material (thrombus/debris) in saphenous vein coronary bypass graft(s) (3.0 mm – 5.0 mm) during percutaneous transluminal coronary angioplasty and/or stenting procedures. The Proxis System is also indicated to control the flow of fluids and aid in the removal of fresh, soft emboli and thrombi in the coronary and peripheral vasculature. The safety and effectiveness of this device as an embolic protection system has not been established in the cerebral, carotid or peripheral vasculature; native coronary arteries; or for treatment of patients with acute myocardial infarction.

The Proxis Embolic Protection System is used in conjunction with other percutaneous transluminal coronary angioplasty devices (PTCA). It is compatible with 8F guide catheters. The Proxis System protects the patient from distal embolization by preventing antegrade flow of emboli released during a PTCA and then removing it from the vessel. The Proxis System consists of an Evacuation Sheath Catheter, Accessory Pack (contains an inflation system, evacuation syringe and double y-adaptor) and an optional additional accessory called the Proxis Infusion Catheter (packaged separately). The Evacuation Sheath Catheter is loaded into the hemostasis valve and tracked down to the distal portion of the guide catheter. The Evacuation Sheath lines the inner lumen of the distal end of the guide catheter. When the sealing balloons are inflated, the proximal balloon seals against the guide catheter wall and the distal balloon seals against the blood vessel wall and the antegrade flow of the fluid in the target vessel is stopped. The stagnation of flow is accomplished before any devices touch or cross the lesion(s). This minimizes the distal release of embolic material. Interventional devices are passed through the evacuation sheath to the treatment site and the procedure is performed in stagnant fluid. After the procedure, fluid and particles from the procedure are evacuated using the Evacuation Syringe. The Proxis Infusion Catheter may be used to augment the retrograde flow during the evacuation by infusing saline distal to the treatment site while simultaneously applying vacuum to evacuate fluid and particles from the treatment site.

The Premere™ Delivery Sheath is indicated for use in intravascular introduction of therapeutic devices into the left atrium of the heart through the septal wall.

The Premere™ Delivery Sheath consists of a non-tapered catheter introducer and an obturator. The distal portion is tapered to facilitate positioning and crossing the atrial septum. The Premere™ Delivery Sheath is intended to provide a pathway for introduction of therapeutic devices into the right and left atrium. The delivery sheath is fitted with a hemostasis valve at the proximal end to allow insertion of devices while minimizing blood loss and a side port with a three-way stopcock for infusion, blood sampling and pressure monitoring. The sheath is provided with a stainless steel braid and a radiopaque material on outer jacket with a high-contrast radiopaque marker at the tip. The obturator is radiopaque with a tapered tip and is compatible with a 0.038" guiding wire.

The Proxis System controls the flow of fluids in the coronary and periphery vasculature. This is achieved by the temporary occlusion of vessels and holding the column of fluid in the vessel stagnant. The stagnant column can be used to aid in the visualization of the lesion or be used as a means of local and temporary delivery of therapeutic solution(s). The safety and efficacy of this device as an embolic protection system has not been established. The Proxis Flow Control device is not indicated for use for embolic protection.

The Proxis System has four major components: The Evacuation Sheath Catheter, the Inflation System, Infusion Catheter, and an Evacuation syringe. The Evacuation Sheath Catheter has two low-pressure compliant sealing balloons that are inflated simultaneously. The proximal balloon stays within the guide catheter while the distal balloon resides in the arterial vessel. Radiopaque markers at the two balloon sites facilitate visualization and intravascular placement of the catheter prior to inflation. The Evacuation Sheath has sufficiently large inner diameter to accommodate standard therapeutic devices within its size range. The balloons are inflated using the Inflation Svstem. Devices can be deployed through the Evacuation sheath to the target site before, during or after the sealing balloons are inflated to occlude the vessel. Infusing ~0.5cc of contrast dye through the guide catheter will produce a continuous "roadmap" of the lesion as an aid for the physician in guiding the therapeutic device to the lesion site. Alternatively, while the vessel is occluded, therapeutic solutions like anticoagulant, cardioplegia and thrombolytics may be infused through the guide catheter and stagnated in the target vessel/lesion during the delivery of the therapeutic device or after the deployment of the therapeutic device. The Evacuation syringe is provided for the removal of the fluid and the emboli/thrombi during aspiration. The infusion catheter may be used to infuse saline to augment the retrograde flow of fluid and the removal the emboli/thrombi.

The Venture™ Wire Control Catheter is indicated for directing, steering, controlling, and supporting a guide wire to access discreet regions of the coronary and peripheral vasculature. It may also be used for manual delivery of saline solution or diagnostic contrast agents.

The Venture Wire Control Catheter is a single use, over-the-wire support catheter with a radiopaque deflectable tip. A rotating knob at the handle controls the tip deflection angle. The tip can be deflected continuously up to about 90° from the catheter axis. The device is compatible with all 0.014" guidewires. It is torqueable and can be use to instantaneously shape, and control the curvature of the guidewire while in use as well as provide support to the guidewire when needed. A luer attachment is also provided to allow for the manual injection of dye through the guidewire lumen of the catheter

The Proxis Flow-Control device is a dual balloon catheter. It has four major components: The Evacuation Sheath Catheter, the Inflation System, Infusion Catheter System, and an Evacuation syringe. The Evacuation Sheath also has two low-pressure compliant balloons that are inflated simultaneously. The proximal balloon stays within the guide catheter while the distal balloon resides in the arterial vessel. Radiopaque markers at the two balloon sites facilitate visualization and intravascular placement of the catheter prior to inflation. The Evacuation Sheath has an inner diameter of 0.058 inches and can accommodate standard therapeutic devices that have profiles of 0.058 inches or lower. The balloons are inflated using the Inflation System. Devices can be deployed through the Evacuation sheath to the target site before, during or after the Proxis balloons are inflated, and the vessel occluded. Infusing less than 0.5cc of contrast dye through the guide catheter will produce a "roadmap" of the lesion as an aid for the physician in guiding the therapeutic device to the lesion site. Alternatively, less than 0.5cc of therapeutic solutions like anticoagulant, cardioplegia and thrombolytics may be infused through the guide catheter and stagnated in the target vessel/lesion during the delivery of the therapeutic device or after the deployment of the therapeutic device while the vessel is occluded. The Evacuation syringe is provided in the event that removal of contrast, or therapeutic solution is desired. If distal perfusion of fluid is needed during evacuation, the Infusion Catheter System may be used.
