Intended Use

The Attain Hybrid guide wire is intended to aid in the placement of Medtronic transvenous left ventricular leads in the coronary vasculature.

Device Story

Attain Hybrid Guide Wire is a flexible, small-diameter wire used as a track to direct and pass transvenous left ventricular leads into the coronary vasculature. Operated by physicians in a clinical setting, the wire facilitates lead placement by providing a path for the lead to follow. The device is a modification of a predicate, featuring updated PTFE formulation and adjusted tip/distal segment stiffness. It functions as a mechanical guide; it does not involve electronic processing, software, or AI. Clinical benefit is derived from the safe and accurate navigation of leads to the target site within the heart's coronary anatomy.

Clinical Evidence

Bench testing only. Verification studies included coating adhesion, dimensional verification, tip integrity, tip deflection force, distal tip stiffness, guide wire perforation, seal integrity, lubricity, durability, and torque response. Biocompatibility testing performed per ISO 10993-1 included cytotoxicity, irritation, systemic toxicity, hemocompatibility, thrombosis, pyrogenicity, complement activation, and sensitization. All tests met specified acceptance criteria.

Technological Characteristics

Flexible guide wire; PTFE coating; variable tip and distal segment stiffness. Sterilization validated; shelf life evaluated. Biocompatibility per ISO 10993-1. No electronic components, energy sources, or software.

Indications for Use

Indicated for patients requiring placement of Medtronic transvenous left ventricular leads within the coronary vasculature.

Regulatory Classification

Identification

A catheter guide wire is a coiled wire that is designed to fit inside a percutaneous catheter for the purpose of directing the catheter through a blood vessel.

Special Controls

*Classification.* Class II (special controls). The device, when it is a torque device that is manually operated, non-patient contacting, and intended to manipulate non-cerebral vascular guide wires, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

Dear Mia Hunt.

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 (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. 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.

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

{1}------------------------------------------------

Part 807); labeling (21 CFR Part 801); medical device reporting of medical devicerelated adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Division of Industry and Consumer Education at its toll-free number [phone] or [phone] or at its Internet address

http://www.fda.gov/MedicalDevices/ResourcesforYou/Industry/default.htm. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to

http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
