Dear Nancy Frame:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). 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.
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.

### Device Description
The Perfect-O is a medical-grade, disposable catheter designed to provide consistent and precise stent implantation in aorto-ostial lesions during coronary or peripheral interventional procedures. It consists of a flexible distal shaft that can be placed at the targeted aorto-ostial location. An atraumatic, compliant balloon inflated with saline/contrast media, and a radiopaque marker at the distal tip of the catheter facilitates precise stent placement at the aorto-ostial lesion.
The Perfect-O consists of three (3) components:
- **Ostial Positioning Catheter:** The primary component of the Perfect-O system is a single-use catheter composed of a proximal hub, hypotube, flexible distal shaft, and compliant distal balloon. The proximal hub features a standard luer connection for attachment to the supplied stopcock and syringe, allowing controlled balloon inflation and deflation. The hypotube extends distally from the hub, providing pushability and containing the inflation lumen that delivers the saline/contrast mixture to the balloon. It terminates near the proximal end of the flexible shaft, which includes a separate lumen that permits passage of interventional devices. The compliant distal balloon inflates to act as a temporary positioning aid against the vessel ostium, facilitating accurate stent alignment. A radiopaque marker near the distal tip provides fluoroscopic visibility during positioning and deployment.
- **2-Way Stopcock:** A single-use stopcock supplied with the system allows controlled balloon inflation and deflation. It connects the proximal hub of the ostial positioning catheter to the syringe and provides fluid isolation during the procedure.
{5}
- Syringe: A single-use syringe is provided for balloon inflation and deflation using a saline/contrast mixture as described in the Instructions for Use (IFU). The syringe interfaces with the stopcock and catheter hub to enable controlled delivery and withdrawal of inflation media.
#### **Indications for Use**
The Perfect-O Ostial Positioning Catheter is intended for use in aorto-ostial procedures to introduce and position stents and other interventional devices within the coronary and peripheral vasculature. In addition, the Perfect-O Ostial Positioning Catheter is intended to facilitate the alignment of interventional devices and function as an alignment tool. The Perfect-O Ostial Positioning Catheter is not intended for use and has not been evaluated for use in the neurovasculature.

| Product Description | The Ostial PRO Stent Positioning System is a medical grade, disposable guide wire system designed to provide consistent and precise stent implantation in aorto-ostial lesions during coronary or peripheral interventional procedures. It consists of a flexible guide wire shaft that can be easily and accurately placed in the targeted aorto-ostial location. Low profile, atraumatic, radiopaque expandable "feet" at the distal tip of the guide wire system facilitate precise stent placement in the aorto-ostial lesion. | The Perfect-O Ostial Positioning Catheter, a sterile, single-use intravascular device, is designed to enable precise stent placement in aorto-ostial lesions during coronary or peripheral interventional procedures. Its flexible, coiled shaft, combined with a distal atraumatic, compliant balloon and a distal radiopaque marker band, facilitates visualization and positioning. The device is designed to minimize the risk of stent misplacement, potentially reducing procedure time and complications, thereby improving patient safety. |

# **Performance Data**
# **Biocompatibility**
The biocompatibility evaluation for the Perfect-O Ostial Positioning Catheter was conducted in accordance with the International Standard ISO 10993-1 "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The Perfect-O Ostial Positioning Catheter is considered an externally communicating device in contact with circulating blood and tissue for a limited period of time (<24 hours) during use. The battery of tests included the following:
- Cytotoxicity
- Sensitization
- Intracutaneous Reactivity
- Acute Systemic Toxicity
- Pyrogenicity
- Hemolysis
- Complement Activation
- Thrombogenicity
# **Performance Data - Bench**
The device design was verified through bench testing. Tests included dimensional verification, simulated use, tensile strength, flexibility and kink, torque strength, radiopacity, corrosion resistance, structural integrity, balloon rated burst pressure, balloon rated burst volume, balloon compliance, balloon inflation and deflation time, coating integrity, and particulate evaluation.
# **Conclusion**
Based on the indications for use, biocompatibility, bench and usability testing, the subject Perfect-O Ostial Positioning Catheter did not raise any new questions of safety or effectiveness compared to the predicate. The Perfect-O Ostial Positioning Catheter is substantially equivalent to the Ostial Pro Stent Positioning System.
