Intended Use
The Stingray LP Catheter is indicated for directing, steering, controlling, and supporting a guidewire in order to access discrete regions of the coronary vasculature. When used as part of the system consisting of the CrossBoss™ Catheter, and Stingray Guidewire, the Stingray LP Catheter is indicated for use to facilitate the intraluminal placement of conventional guidewires beyond stenotic coronary lesions (including chronic total occlusions [CTOs]) prior to PTCA or stent intervention.
Device Description
The Stingray LP Catheter facilitates the placement, support and steering of a guidewire into discrete regions of the coronary vasculature through the central guidewire lumen or through one of two side-ports. These side-ports are on opposite sides of the balloon and are identified by radiopaque markers. The side-ports communicate with the central guidewire lumen and facilitate guidewire steering (at an angle to the central lumen) by allowing the quidewire to exit the Stingray LP Catheter. The Stingray LP Catheter contains a small balloon used for fluoroscopic orientation on the distal tip of a flexible shaft. The distal end of the catheter is hydrophilic coated. The Stingray LP Catheter is compatible with 6F guide catheters with minimum inner diameter of 0.070 in (1.7 mm), and may be used with guidewires ≤0.014 in (0.36 mm).

No
The description focuses on the mechanical function of the catheter and its components (guidewire lumen, side-ports, balloon). There is no mention of any computational or algorithmic processing, let alone AI/ML. The performance studies are bench and biocompatibility testing, not studies evaluating algorithmic performance.

No
The device is a catheter designed to assist in the placement and manipulation of guidewires within the coronary vasculature to facilitate interventions, not to treat a condition itself.

No

The device is indicated for directing, steering, controlling, and supporting a guidewire to access discrete regions of the coronary vasculature, and to facilitate the intraluminal placement of conventional guidewires beyond stenotic coronary lesions. This describes an interventional or therapeutic function, not a diagnostic one.

No

The device description clearly details a physical catheter with a balloon, guidewire lumen, side-ports, and a flexible shaft, indicating it is a hardware medical device.

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

Here's why:

  • Intended Use: The intended use clearly describes a device used in vivo (within the body) to facilitate the placement of guidewires in the coronary vasculature for interventional procedures (PTCA or stent intervention).
  • Device Description: The description details a catheter with a balloon, guidewire lumens, and side-ports designed for navigating and supporting guidewires within blood vessels. This is a physical medical device used directly on the patient.
  • Lack of Diagnostic Function: There is no mention of the device being used to analyze samples (blood, tissue, etc.) or to provide diagnostic information about a patient's condition. Its function is purely procedural and interventional.
  • Input Imaging Modality: The input imaging modality is fluoroscopic, which is used for real-time visualization during in vivo procedures, not for analyzing samples.

IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Dear Gabrielle Reynolds:

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.

Device Description

The Stingray LP Catheter facilitates the placement, support and steering of a guidewire into discrete regions of the coronary vasculature through the central guidewire lumen or through one of two side-ports. These side-ports are on opposite sides of the balloon and are identified by radiopaque markers. The side-ports communicate with the central guidewire lumen and facilitate guidewire steering (at an angle to the central lumen) by allowing the quidewire to exit the Stingray LP Catheter. The Stingray LP Catheter contains a small balloon used for fluoroscopic orientation on the distal tip of a flexible shaft. The distal end of the catheter is hydrophilic coated. The Stingray LP Catheter is compatible with 6F guide catheters with minimum inner diameter of 0.070 in (1.7 mm), and may be used with guidewires ≤0.014 in (0.36 mm).

Indications for Use / Intended Use

The Stingray LP Catheter is indicated for directing, steering, controlling, and supporting a guidewire in order to access discrete regions of the coronary vasculature.

When used as part of the system consisting of the CrossBoss™ Catheter, Stingray LP Catheter, and Stingray Guidewire, the Stingray LP Catheter is indicated for use to facilitate the intraluminal placement of conventional guidewires beyond stenotic coronary lesions (including chronic total occlusions [CTOs]) prior to PTCA or stent intervention.
