Indications for Use
The Halo™ Single-Loop Microsnare Kit is intended for use in the retrieval and manipulation of atraumatic foreign bodies located in the coronary and peripheral cardiovascular system and the extra-cranial neurovascular anatomy.
Device Story
Halo Single-Loop Microsnare Kit is a percutaneous retrieval device used to capture and reposition or remove atraumatic foreign bodies from the cardiovascular and neurovascular systems. The kit includes a microsnare (gold-plated tungsten coil, nitinol loop/shaft), a microsnare catheter (Pebax tubing, platinum/iridium marker band), a peel-away introducer, and a torque handle. The device is advanced through a sheath to the target site under imaging guidance. The physician manipulates the torque handle to deploy the super-elastic, pre-formed snare loop to grasp the foreign body. The device is intended for use by clinicians in clinical settings. It benefits patients by providing a minimally invasive method for retrieving misplaced or foreign objects, potentially avoiding more invasive surgical interventions.
Clinical Evidence
No clinical data. Substantial equivalence is supported by bench testing, including mechanical performance (tensile, torque, kink, flexural modulus, leakage, radiopacity) and biocompatibility testing (ISO 10993-5, -10, -11, -4).
Technological Characteristics
Materials: Nitinol loop/shaft, gold-plated tungsten coil, Pebax catheter tubing, platinum/iridium marker band. Principle: Super-elastic snare loop for percutaneous retrieval. Dimensions: 3F catheter, 150/175cm length, 2/4/7mm loop diameters. Connectivity: None. Sterilization: 100% EtO.
Indications for Use
Indicated for retrieval and manipulation of atraumatic foreign bodies in coronary, peripheral cardiovascular, and extra-cranial neurovascular anatomy.
Regulatory Classification
Identification

Dear Ana Jimenez-Hughes:
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. 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 located 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.
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
{1}------------------------------------------------
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

#### A comparison of the technological characteristics of the subject device and the Technological Characteristics: predicate devices shows the Halo™ Single-Loop Microsnare Kit to be substantially equivalent to the current marketed predicate devices.
The proposed Halo™ Single-Loop Microsnare Kit is similar in materials of construction, dimensional specifications, design and sterilization process to the primary predicate device, the Amplatz Goose Neck Microsnare (K970668) and the reference predicate, the ONE Snare Endovascular Microsnare System (K142265). The Halo™ Single-Loop Microsnare Kit consist of (1) microsnare made of gold plated Tungsten coil and nitinol loop; (1) microsnare catheter made of Pebax tubing/Platinum Iridium marker band, (1) peel-away introducer and (1) torque handle.
The Halo™ Single-Loop Microsnare Kit has the same principle of operation and indications for use as the predicate devices. The system is advanced through a sheath proximal to the target under imaging. The system is then manipulated to grab and reposition or grab and remove a foreign body. The intended use of the proposed device and the predicate device is the same: for use in the retrieval and manipulation of atraumatic foreign bodies located in the coronary and peripheral cardiovascular system and the extra-cranial neurovascular anatomy.
