You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. U.S. Food & Drug Administration 10903 New Hampshire Avenue Silver Spring, MD 20993 www.fda.gov {1} K260816 - Brian Li Page 2 If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download). Your device is also subject to, among other requirements, the Quality Management System Regulation (QMSR) (21 CFR Part 820), which includes, but is not limited to, ISO 13485 clause 7.3 (Design controls), ISO 13485 clause 8.3 (Nonconforming product), ISO 13485 clause 8.5.2 (Corrective action), and ISO 13485 clause 8.5.3 (Preventative action). Please note that regardless of whether a change requires premarket review, the QMSR requires device manufacturers to review and approve changes to device design and production (ISO 13485 clause 7.3 and ISO 13485 clause 7.5) and document changes and approvals in the Medical Device File (ISO 13485 clause 4.2.3). Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the Quality Management System Regulation (QMSR) (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050. All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E).

Available in 5F and 6F sizes. The OptiCross HD and OptiCross 6 HD 60 MHz Coronary Imaging Catheters are sterile, short rail imaging catheters. Available in 5F and 6F sizes. All catheters consist of two main assemblies: 1. Imaging Core 2. Catheter Body | | Page 1 of 3 {5} Boston Scientific 300 Boston Scientific Way Marlborough, MA 01752-1234 (508) 683-4000 www.bostonscientific.com The imaging core is composed of a hi-torque, flexible, rotating drive cable with a radial looking 40 MHz or 60 MHz ultrasonic transducer at the distal tip. An electro-mechanical connector interface at the proximal end of the catheter makes the connection to the Motordrive Unit (MDU5 PLUS™) Instrument. The MDU5 PLUS-catheter interface consists of an integrated mechanical drive socket and electrical connection. The catheter body is comprised of four sections: 1. Hub Sub-Assembly 2. Telescope Sub-Assembly 3. Proximal Shaft 4. Distal Shaft with the Distal Guidewire Lumen The distal shaft with the distal guidewire lumen and proximal shaft sections comprise the "working length" of the catheter, and the telescoping sub-assembly section remains outside of the guiding catheter. The catheter body has a distal shaft with the distal guidewire lumen with proximal exit at 1.6 cm from the distal end. A radiopaque (RO) marker is embedded in the catheter body at 0.5 cm from the distal tip. Two insertion markers are located on the proximal shaft (a single insertion marker at 90 cm and a single insertion marker at 100 cm from the distal tip) for the 5F catheters; three insertion markers are located on the proximal shaft (a single insertion marker at 90 cm and a double insertion marker at 100 cm from the distal tip) for the 6F catheters. These markers facilitate estimation of catheter position relative to the distal tip of the guide catheter. The proximal shaft is attached to the telescoping sub-assembly section via a strain relief connection. The telescoping sub-assembly allows the imaging core to be advanced and retracted for 15 cm of linear movement. The corresponding movement of the transducer occurs from the proximal end of the guidewire exit port to the proximal end of the distal shaft with the distal guidewire lumen. The telescope sub-assembly has proximal markers for lesion length assessment, consisting of a series of marks spaced 1 cm apart on the telescope body. A flush port with a one-way check valve is used to flush the interior of the catheter body and maintain a flushed condition. The catheter must be flushed with heparinized saline prior to use, as this provides the acoustic coupling media required for ultrasonic imaging. The one-way check valve helps retain saline in the catheter during use. The Coronary Imaging Catheter, 17.78 cm (7 in) extension tube, 3 cm³ (3 cc) and 10 cm³ (10 cc) syringes, and 4-way stopcock are provided in a single use sterilized package. ## Intended Use/indications for Use This catheter is intended for ultrasound examination of coronary intravascular pathology only. Intravascular ultrasound imaging is indicated in patients who are candidates for transluminal coronary interventional procedures.

The OptiCross™ and OptiCross™ 6 Coronary Imaging Catheters utilize a 40 MHz transducer used for imaging. The OptiCross™ HD and OptiCross™ 6 HD catheters utilize a 60 MHz transducer used for higher definition imaging. All catheters interface with the same IVUS imaging system in the same way as the predicate. ## Non-Clinical Performance Data Determination of substantial equivalence is based on an assessment of non-clinical performance bench testing verification data. ## Bench Testing Bench testing verification was performed to evaluate physical integrity, functionality, and performance of the OptiCross™, OptiCross™ 6, OptiCross™ HD, and OptiCross™ 6 HD Coronary Imaging Catheter devices. Performance criteria includes catheter robustness and performance requirements. ## Clinical Performance Data Not applicable; determination of substantial equivalence is not based on clinical performance data. Substantial equivalence is based on an assessment of non-clinical performance data. ## Conclusion Based on a comparison of intended use/indications for use, technological characteristics, and fundamental design technology, including non-clinical performance bench testing verification data, the modified devices (OptiCross™, OptiCross™ 6, OptiCross™ HD, OptiCross™ 6 HD, OptiCross™ (Bagless), OptiCross™ 6 (Bagless), OptiCross™ HD (Bagless), OptiCross™ 6 HD (Bagless)) and predicate devices per K230453 (OptiCross™ HD, OptiCross™ 6 HD), support a determination of substantial equivalence and raise no new issues of safety and effectiveness.
