Intended Use

The Sonicath Ultra™ 3.2F 20MHz Imaging Catheter is intended for ultrasound examination of peripheral intravascular pathology only. Intravascular ultrasound imaging is indicated in patients who are candidates for transluminal interventional procedures.

Device Story

Sterile, single-use, 20 MHz intravascular ultrasound (IVUS) imaging catheter; 3.2F distal crossing profile. Operates with BSC ClearView Ultra™, Galaxy®, Galaxy2™, or iLab® imaging instruments. Consists of sheath assembly and rotating imaging core with piezoelectric transducer. Transducer converts electrical energy to ultrasonic energy for tissue imaging; converts returned echoes to electrical signals for instrument display. Proximal telescoping section allows core advancement/retraction across anatomy without moving sheath. Used in clinical settings by physicians during peripheral vascular interventions. Provides real-time visualization of intravascular pathology to guide clinical decision-making and interventional procedures.

Clinical Evidence

Bench testing only. Evaluated physical integrity and functionality, including dimensional, tensile, and pressure testing of the catheter sheath support. Biocompatibility testing performed per USP and EN ISO 10993 standards. Acoustic output remains unchanged from predicate.

Technological Characteristics

20 MHz piezoelectric transducer; 3.2F distal profile; short rail (SR) design. Materials: modified Low Density Polyethylene (LDPE) resin for sheath support. Connectivity: compatible with BSC ClearView Ultra™, Galaxy®, Galaxy2™, and iLab® imaging systems. Sterilization: sterile, single-use.

Indications for Use

Indicated for patients who are candidates for transluminal interventional procedures requiring ultrasound examination of peripheral intravascular pathology.

Regulatory Classification

Identification

A diagnostic ultrasonic transducer is a device made of a piezoelectric material that converts electrical signals into acoustic signals and acoustic signals into electrical signals and intended for use in diagnostic ultrasonic medical devices. Accessories of this generic type of device may include transmission media for acoustically coupling the transducer to the body surface, such as acoustic gel, paste, or a flexible fluid container.

#### Description of the Device:

The Sonicath Ultra™ 3.2F 20MHz Imaging Catheter is a sterile, single-use, short rail (SR), 20 MHz imaging catheter with a 3.2F distal crossing profile. The catheter is intended to operate with the BSC ClearView Ultra™, Galaxy®, Galaxy2™, or iLab® intravascular ultrasound imaging instruments. The catheter and instrument form an imaging system that is intended for the ultrasonic examination of peripheral intravascular pathology only.

The catheter consists of two (2) main assemblies: a sheath assembly and an imaging core assembly. The sheath assembly is the outer part of the catheter that comprises much of the working length of the device. The imaging core is internal to the sheath assembly and rotates independently of the sheath. The imaging core contains the piezoelectric transducer that converts electrical energy from the instrument to ultrasonic energy that is in turn transmitted. The transducer converts the returned ultrasonic energy into electrical energy for display on the instrument. The rotating imaging core drive shaft directs the path of the ultrasonic energy (beam) from the transducer. A proximal telescoping section allows the imaging core to be retracted and advanced, across an anatomical region of interest, without requiring movement of the sheath within the anatomy.

#### Sonicath Ultra™ 3.2F 20MHz Imaqing Catheter:

The modified Sonicath Ultra™ 3.2F 20MHz Imaging Catheter is identical in all aspects to the current Sonicath Ultra™ 3.2F 20MHz Imaging Catheter except for the following change:

- Changed catheter sheath support material from one Low Density Polyethylene . (LDPE) resin formulation to another.

{2}------------------------------------------------

Design verification testing confirms that predetermined acceptance criteria were met and no new issues of safety or efficacy have been raised with the use of this new catheter sheath support material.

#### Intended Use/Indications:

The Sonicath Ultra™ 3.2F 20MHz Imaging Catheter is intended for ultrasound examination of peripheral intravascular pathology only. Intravascular ultrasound imaging is indicated in patients who are candidates for transluminal interventional procedures.

### Device Technology Characteristics and Comparison to Predicate Device:

The modified Sonicath Ultra™ 3.2F 20MHz Imaging Catheter is the same as the predicate device, the Sonicath Ultra™ 3.2F 20MHz Imaging Catheter cleared June 20, 1997, in all aspects except one -- change in sheath support resin formulation.

#### Non-clinical Test Results:

Bench and biological safety testing demonstrate that the modified Sonicath Ultra™ 3.2F 20MHz Imaging Catheter meets performance requirements and is safe and effective for its intended use.

#### Bench Testing:

Bench testing was performed to evaluate the physical integrity and functionality of the modified Sonicath Ultra™ 3.2F 20MHz Imaging Catheter. This testing included dimensional and functional (e.g., tensile, pressure) testing of the catheter sheath support and the full, sterile device. The results demonstrated that the device satisfies all performance, physical and functional requirements.

APF 1 9 2005

#### Biological Safety Testing:

The Sonicath Ultra™ 3.2F 20MHz Imaging Catheter was subjected to a series of biocompatibility tests per USP and EN ISO 10993 standards. The results of the biocompatibility testing demonstrate that the modified Sonicath Ultra™ 3.2F 20MHz Imaging Catheter is acceptable for it intended use.

#### Acoustic Output Testing:

Acoustic Output testing was not required for the modified Sonicath Ultra™ 3.2F 20MHz Imaging Catheter as the formulation change to the sheath support has no effect on acoustic output.

Per the FDA Guidance, Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers (September 30 1997), acoustic output measurements for the modified Sonicath Ultra™ 3.2F 20MHz Imaging Catheter remain unchanged from its predicate device, the Sonicath Ultra™ 3.2F 20MHz Imaging Catheter.

#### Conclusion:

The modified Sonicath Ultra™ 3.2F 20MHz Imaging Catheter utilizes the same design features and has the same intended use as the predicate device, the Sonicath Ultra™ 3.2F 20MHz Imaging Catheter. The tests conducted support a determination of substantial equivalence of the modified device to the predicate device.
