No
The document describes a device that uses OCT imaging for guidance during atherectomy but does not mention any AI or ML components for image analysis, decision support, or other functions.
Yes.
The device itself is an atherectomy catheter, which is a medical device used to perform a therapeutic procedure (plaque removal).
Yes
Explanation: The "Device Description" states, "The Pantheris LV catheter incorporates an optical fiber that allows real-time diagnosis of vessel condition and morphology." This explicitly describes a diagnostic function.
No
The device description clearly outlines hardware components including a catheter, a Lightbox Sled, and a Lightbox Imaging Console.
Based on the provided information, the Pantheris LV System is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Pantheris LV System Function: The Pantheris LV System is a medical device used directly within the body (in vivo) to physically remove plaque from blood vessels. It uses OCT imaging to guide this procedure, but the imaging is for real-time visualization during the intervention, not for analyzing samples taken from the body.
- Intended Use: The intended use clearly states it is for "remove plaque (atherectomy)" and is an "adjunct to fluoroscopy by providing images of vessel lumen, wall structures, and vessel morphologies." This describes a therapeutic and interventional procedure, not a diagnostic test performed on a sample.
Therefore, the Pantheris LV System falls under the category of an interventional medical device, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The Pantheris LV System is indicated to remove plaque (atherectomy) from partially occluded native or restenotic vessels, including in-stent restenosis (ISR), in the peripheral vasculature with a reference diameter of 3.0 mm, using OCT-assisted orientation and imaging. The system is an adjunct to fluoroscopy by providing images of vessel lumen, wall structures, and vessel morphologies. The Pantheris LV System is NOT intended for use in the iliac, coronary, cerebral, renal or carotid vasculature.

Device Description
The Pantheris LV catheter combines the use of Avinger's optical coherence tomography (OCT) technology with peripheral vascular atherectomy capabilities. The Pantheris LV System consists of the Pantheris LV catheter, a Lightbox Sled with integrated umbilical (referred to as "Sled"), and the Lightbox Imaging Console (referred to as "Lightbox").
The subject device of this submission is a product line extension of the Pantheris SV System reviewed and cleared earlier under K182341.
The Pantheris LV catheter is a 7 French device with a working length of 110 cm. It is comprised of two components-an outer support catheter and an inner assembly or drive shaft. It is provided sterile and is a single-use device compatible with 5 Fr vascular sheaths. The Pantheris LV catheter incorporates an optical fiber that allows real-time diagnosis of vessel condition and morphology as well as OCT-guided atherectomy during the procedure with its connection to the Lightbox.
The Pantheris LV catheter is to be used in a healthcare facility, such as a cardiac catheter lab or a hospital. It is to be used and in contact with patient tissue for less than 24 hours and is made of materials that are biocompatible.
This Traditional 510(k) builds on the Pantheris SV (K182341) and Pantheris v1.4 (K173862) atherectomy catheter designs and details additional minor modifications to the design of the Pantheris catheter family to add in functionality of the device.

Device Description and Proposed Modifications
The Pantheris LV catheter combines the use of Avinger's optical coherence tomography (OCT) technology with peripheral vascular atherectomy capabilities. The Pantheris LV System consists of the Pantheris LV catheter, a Lightbox Sled with integrated umbilical (referred to as "Sled"), and the Lightbox Imaging Console (referred to as "Lightbox").
The subject device of this submission is a product line extension of the Pantheris SV System reviewed and cleared earlier under K182341.
The Pantheris LV catheter is a 7 French device with a working length of 110 cm. It is comprised of two components-an outer support catheter and an inner assembly or drive shaft. It is provided sterile and is a single-use device compatible with 5 Fr vascular sheaths. The Pantheris LV catheter incorporates an optical fiber that allows real-time diagnosis of vessel condition and morphology as well as OCT-guided atherectomy during the procedure with its connection to the Lightbox.
The Pantheris LV catheter is to be used in a healthcare facility, such as a cardiac catheter lab or a hospital. It is to be used and in contact with patient tissue for less than 24 hours and is made of materials that are biocompatible.
This Traditional 510(k) builds on the Pantheris SV (K182341) and Pantheris v1.4 (K173862) atherectomy catheter designs and details additional minor modifications to the design of the Pantheris catheter family to add in functionality of the device.

Indications for Use
The indication for use for the Pantheris LV catheter is:
The Pantheris LV System is intended to remove plaque (atherectomy) from partially occluded native or restenotic vessels, including in-stent restenosis (ISR), in the peripheral vasculature with a reference diameter of 3.0 mm to 7.0 mm, using OCT-assisted orientation and imaging. The system is an adjunct to fluoroscopy by providing images of vessel lumen, wall structures, and vessel morphologies. The Pantheris LV System is NOT intended for use in the iliac, coronary, cerebral, renal or carotid vasculature.
Both the subject device and the reference device have the same intended use of debulking plaque in the lumen of peripheral arteries sized 3 to 7 mm in diameter. The subject device and predicate device are made from the same materials and use the same packaging.
Comparison of Technological Characteristics with the Predicate and Reference Devices
Avinger Inc. has identified the Pantheris SV catheter (K182341) as the predicate device and the Pantheris v1.4 (K173862) catheter as the reference device for the Pantheris LV catheter.
The Pantheris LV catheter is substantially equivalent to the predicate device with its design of a jog in the distal segment of the cannula that results in the cutter contacting target tissue as is the design of the Pantheris SV catheter. The Pantheris LV catheter is substantially equivalent to the Pantheris v1.4 catheter in its outer diameter (7 Fr) and indications of use in peripheral vessels 3 to 7 mm in diameter.
The Pantheris LV catheter is substantially equivalent to the predicate and reference devices in its clinical utility based upon the following factors:
- The three devices are intended to be used to debulk lesions disrupting and restricting blood flow in peripheral vessels.
- · The three devices are used in cardiac catheter labs in either a hospital or an office-based lab.
- · The three devices are advanced to the target lesion through an indwelling vascular sheath.
- · Advancement of the three devices is monitored by external fluoroscopy and the catheters' on-board intravascular OCT imaging component.
- · The three devices consist of a rotating cutter that actively engages the plaque
6
tissue causing removal of the occlusive tissue and a power source to cause the device rotation of the cutter and display the OCT image during the procedure.
