Intended Use
The Microcatheter is intended for general intravascular use, including peripheral and coronary vasculature. Once the subselective region has been accessed, the microcatheter can be used for the controlled and selective infusion of diagnostic, embolic or therapeutic materials into vessels. The catheter should not be used in the cerebral vessels.
Device Description
The Maestro Microcatheter is available in working length sizes 110cm, 130cm, 150cm, 165cm and 175cm lengths. The distal tip of the microcatheter is offered in straight or pre-shaped 45 degree and swan neck configurations. The proximal end of the catheter consists of a molded winged hub with a tapered strain relief. The outer surface of the distal 80cm of the microcatheter shaft is coated with a hydrophilic coating designed to facilitate the introduction of the catheter into the vasculature. The microcatheter incorporates a radiopaque marker at the distal tip to facilitate fluoroscopic visualization. The Maestro Microcatheter is offered with two 3ml syringes.
More Information

No
The device description and performance studies focus on the physical characteristics and mechanical performance of a microcatheter, with no mention of AI or ML capabilities.

No
The device itself is not a therapeutic device but is used for the "controlled and selective infusion of diagnostic, embolic or therapeutic materials into vessels." It is a delivery system for therapeutic agents, not a therapeutic agent itself.

No

Explanation: The device is a microcatheter used for the infusion of materials, including diagnostic materials, into vessels. However, it is not described as performing any diagnostic function itself, such as imaging or measuring a physiological parameter to diagnose a condition. It is a tool for delivering diagnostic substances.

No

The device description clearly details a physical catheter with various lengths, tip configurations, a hub, a hydrophilic coating, and a radiopaque marker. It also mentions included syringes. This indicates a hardware medical device, not a software-only one.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for "general intravascular use, including peripheral and coronary vasculature" and for the "controlled and selective infusion of diagnostic, embolic or therapeutic materials into vessels." This describes a device used within the body for direct intervention or delivery, not for testing samples outside the body.
  • Device Description: The description details a physical catheter with features like working length, tip configurations, coatings, and radiopaque markers. These are characteristics of an invasive medical device, not an IVD.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. IVDs are designed to perform tests on these types of samples.

Therefore, the Maestro Microcatheter is an invasive medical device used for procedures within the vascular system, not an in vitro diagnostic device.

Dear Garry Courtney:

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.

The design and technological characteristics of the subject "longer length" Maestro Microcatheters are substantially equivalent to those of the predicate Maestro Microcatheter. The subject device has the same basic design as the predicate device. The main difference between the subject and the predicate devices is in the working length of the microcatheter – where longer length catheters (165cm and 175cm) are made available to address clinical needs. The comparison between the subject and the predicate devices is based on the following:

  • Same intended use ●
  • Same indications for use
  • Similar material types that meet ISO 10993 biocompatibility requirements
  • Same design ●
  • Same sterilization methods ●
    • Same fundamental technology/principle of operation

No performance standards have been established under Section 514 of the Food, Drug and Cosmetic Act for these devices. Performance testing of the subject Maestro Microcatheters was conducted based on the risk analysis and based on the requirements of the following international standard:

  • ISO 10555-1:2013, Intravascular Catheters Sterile and single-● use catheters - Part 1: General requirements
  • ISO 10993-1:2009, Biological Evaluation of Medical Devices . Part 1: Evaluation and Testing within a risk management process, and FDA quidance Required Biocompatibility Training and Toxicology Profiles for Evaluation of Medical Devices, May 1. 1995
