No
The device description and performance studies focus on mechanical properties and biocompatibility, with no mention of AI/ML terms or functionalities.
No.
The device is intended for retrieving and manipulating objects within the cardiovascular system and hollow viscous, which are interventional procedures rather than therapeutic ones aimed at treating a disease or condition.
No
The device description and intended use clearly state that it is a surgical tool designed to retrieve and/or manipulate objects within the cardiovascular system, not to diagnose medical conditions.
No
The device description clearly outlines physical components made of stainless steel and PTFE, indicating it is a hardware-based medical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for use within the cardiovascular system and hollow viscous to retrieve and/or manipulate objects. This is an in vivo procedure, meaning it is performed on a living organism.
- Device Description: The description details a physical device (snare, sheath, core wire) designed for mechanical manipulation within the body.
- Lack of IVD Characteristics: An IVD device is used to examine specimens (like blood, urine, tissue) outside the body to provide information about a person's health. This device does not perform any such analysis of biological samples.
Therefore, the Radius Snare is a medical device used for interventional procedures, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The Radius Snare is intended for use in the cardiovascular system and hollow viscous to retrieve and/or manipulate objects using minimally invasive surgical procedures. Manipulation procedures include retrieval and/or repositioning of intravascular foreign objects such as coils, balloons, catheters and/or guidewires within the cardiovascular system.

Device Description
The Radius Snare is composed of two primary parts: an outer sheath tube and a core wire with a snare attached to the distal end. The outer sheath acts as a catheter through which the core wire, with snare, slides.
The outer sheath is a stainless steel coil with a PTFE overjacket.
The stainless steel core is the same solid .0135" diameter stainless steel core wire in the FDA cleared Radius PTCA Guidewire. A stainless steel loop is soldered to the distal end of the core wire. The Radius Snare has loop sizes which range from 5 - 35 millimeters. The over-all length of the device is 150 centimeters.
The Radius Snare will be packaged in a mylar/Tyvek pouch and ETO sterilized to SAL 10-2.

Comparison of Technological Characteristics 6.
The Radius Snare is substantially equivalent in material, design and function to the following predicate devices: the Microvena Amplatz Goose Neck Snare/Catheter (K972511) and the Radius PTCA Guidewire (K970466).
The Radius Snare is similar in materials, function and design to predicate Radius PTCA Guidewire (K970466). The Radius Snare uses the Radius PTCA Guidewire as its base and adds a snare onto the distal tip of the core guidewire.
The design and function of the Radius Snare is the same as the Microvena Amplatz Goose Neck Snare/Catheter (K972511). Both devices are delivered via a cathether/outer sheath tube and both have a snare at the distal end. The intended use of the two devices is the same: to retrieve and/or manipulate objects in the cardiovascular system and hollow viscous.

Dear Ms. Finlayson:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
