#### 3. PREDICATE DEVICE AND REFERENCE DEVICES

Ekosonic Endovascular System with Rapid Pulse Modulation (cleared under K111705).

{5}------------------------------------------------

Reference Devices are AngioJet Zelante (K151313), Cordis Maxi LD 14 mm PTA Balloon K963000), and 5 mm balloon catheters [Boston Scientific Sterling PTA Balloon ollatation Catheter (K132430), Abbott Fox SVA PTA Catheter (K092286), Cordis Savvy _ong PTA Balloon (K942094)].

# 4. DESCRIPTION OF THE DEVICE

"hrombolex developed the Bashir™ Endovascular Catheter (Model 7201) to enable elivery of physician-specified fluids, including thrombolytics, into the peripheral circulation. The Bashir™ N-X Endovascular Catheter (Model 7200) is a second model developed for infusion of physician-specified fluids in the pulmonary artery. The Bashir™ N-X differs from the Bashir™ Endovascular Catheter in that the infusion limbs do not expand into an infusion basket but remain collapsed in a straight configuration. The two levice models have a different appearance, namely in the handle design and color, which ensures appropriate use and identification.

The design of the Bashir™ Endovascular Catheter allows for delivery and positioning of he catheter at the target peripheral location via a sheath, over a guidewire using fluoroscopic guidance. Depending on the target location, the infusion can be initiated either n the non-expanded position (for vessels with smaller diameters), or by controlled expansion of the infusion basket to a desired dimension inside the vessel by the interventional specialist under fluoroscopic guidance. The physician-specified solution is then delivered via multiple laser-drilled holes through the infusion limbs of the Bashir™ Endovascular Catheter. After the completion of solution delivery, the infusion limbs are collapsed to a straight position in the case of peripheral vasculature, and then the Bashir™ Endovascular Catheter is retracted into the sheath and removed.

'he handle of the BashirTM N-X Endovascular Catheter has been modified to disable expansion of the basket. The Bashir™ N-X Endovascular Catheter, unexpanded, is thus similar to other straight infusion catheters including the predicate device.

Delivery of the Bashir N-X™ Endovascular Catheter into the pulmonary artery is accomplished using a long guide sheath using standard interventional techniques. The Bashir™ Endovascular Catheter is placed over a guidewire inside the sheath to the desired location under fluoroscopic guidance. The catheter does not come in direct contact with the right atrium, tricuspid valve, right ventricle or pulmonic valve at any time, as it is within a guide sheath.

The Bashir™ Endovascular Catheter and Bashir™ N-X Endovascular Catheter are comprised of common materials used in vascular catheters. The catheter is mechanical and contains no electrical components.

# 5. INDICATION FOR USE

he indications for use / intended use statement for the Bashir™ Endovascular Catheter and the Bashir™ N-X Endovascular Catheter are as follows:

{6}------------------------------------------------

Bashir™ Endovascular Catheter: The Bashir™ Endovascular Catheter is intended for the controlled and selective infusion of physician-specified fluids, including thrombolytics, into the peripheral vasculature.

Bashir™ N-X Endovascular Catheter: The Bashir™ N-X Endovascular Catheter is intended for the controlled and selective infusion of physician-specified fluids into the peripheral and pulmonary artery vasculature.

# 6. COMPARISON OF THE INTENDED USE WITH THE PREDICATE DEVICE

The Bashir™ Endovascular Catheter and the Bashir™ N-X Endovascular Catheter and the predicate device, the Ekosonic Endovascular System, are intended to be used in the same interventional procedures in the same target population (including patients with thrombosis in the vasculature) and have the same primary function of providing a conduit for infusion of solutions. Thus, the Bashir™ Endovascular Catheter and Bashir™ N-X Endovascular Catheter have almost identical intended use / indications for use statements when compared to the predicate device, Ekosonic Endovascular System.

## 7. TECHNOLOGICAL CHARACTERISTICS COMPARED TO THE PREDICATE

The Bashir™ Endovascular Catheter is substantially equivalent to the predicate device regarding its similar intended use, fluid dispersion function, certain aspects of design, materials and sterility.

There are also some differences between the technological characteristics of the Bashir™ Endovascular Catheter, the Bashir™ N-X Endovascular Catheter and the predicate device. These differences do not raise new questions of safety or effectiveness, and there are standard methods and tests that can evaluate the effects of new or different characteristics on safety and performance.

- Infusion limbs at the distal end of the Bashir™ Endovascular Catheter can expand in the peripheral circulation, to facilitate the distribution of infusate in the peripheral vasculature. This is compared to the straight distal end of the predicate catheter. This difference does not raise different questions of safety or effectiveness, since appropriate design verification and validation testing was performed by comparison of the Bashir™ Endovascular Catheter to legally marketed reference devices with expandable features to demonstrate that the radial force exerted is similar for the Bashir™ Endovascular Catheter compared to the balloon reference devices.
- The ultrasound transducers and the electronic and software-controlled components ● of the predicate device are not present for the subject device.
- . The Bashir Catheter and Bashir N-X use the infusion limbs to aid in distribution of fluids. Both models of the Thrombolex device utilize the multiple lumens of the distal infusion region to provide a large surface for infusion of physician-specified fluids and, also to permit flow of native blood containing endogenous thrombolytics through the channel(s) into peripheral the blood vessel or pulmonary artery (Bashir™ N-X Endovascular Catheter).

{7}------------------------------------------------

- The Bashir™ Catheters have the capability for direct blood pressure measurement via the central lumen of the subject devices.
Through product testing, Thrombolex has demonstrated that the technological differences between the subject device and the predicate device do not raise different issues of safety or effectiveness.

# 8. PERFORMANCE TESTING

This 510(k) notification provides performance data to establish the substantial equivalence of the Bashir™ Endovascular Catheter and the Bashir™™™ N-X Endovascular Catheter to the predicate device. The following is a summary of the performance data.
