Intended Use

The Pantheris System is intended to remove plaque (atherectomy) from partially occluded vessels in the peripheral vasculature with a reference diameter of 3.0mm to 7.0mm, using OCT-assisted orientation and imaging. The system as an adjunct to fluoroscopy by providing images of vessel lumen, wall structures and vessel morphologies. The Pantheris System is NOT intended for use in the iliac, coronary, cerebral, renal or carotid vasculature.

Device Story

Pantheris System combines OCT imaging with directional atherectomy for peripheral vascular disease. System components: Pantheris Catheter, Lightbox Sled, Lightbox HS Imaging Console. Catheter transmits light to vessel lumen; Lightbox receives/interprets signals via PC-based processing. Provides real-time OCT images of vessel lumen, wall structures, and morphology to assist physicians during atherectomy. Modification adds optional vessel measurement feature to software; allows physicians to confirm vessel diameter assessments pre- or post-procedure. Used in clinical settings; operated by physicians. Output displayed on console monitors; aids clinical decision-making regarding device sizing for subsequent interventions like balloon angioplasty or stenting. Benefits patient by providing visual guidance for plaque removal.

Clinical Evidence

Bench testing only. Software verification and measurement accuracy testing performed; all acceptance criteria met. No clinical data presented.

Technological Characteristics

System includes catheter, Lightbox Sled, and Lightbox HS Imaging Console (PC-based). Uses Optical Coherence Tomography (OCT) for imaging. Software modification adds optional vessel measurement feature. System is networked/integrated console. No changes to materials or fundamental technology.

Indications for Use

Indicated for atherectomy in partially occluded peripheral vessels (3.0mm-7.0mm diameter) as an adjunct to fluoroscopy. Contraindicated for iliac, coronary, cerebral, renal, or carotid vasculature.

# Device Description and Proposed Modification

The Pantheris System (cleared under K162326) combines the use of Avinger's Optical Coherence Tomography (OCT) technology with peripheral vascular atherectomy capabilities. The Pantheris System consists of the Pantheris Catheter, Lightbox Sled with integrated Umbilical (referred to as "Sled") and the Lightbox HS Imaging Console (referred to as "Lightbox").

{4}------------------------------------------------

The Pantheris Catheter is connected to the Lightbox via the Sled. The Lightbox is an optical transceiver, transmitting light to the intraluminal environment through the optical fiber on the Pantheris Catheter and receiving and interpreting the signal from the tissue using a PC-based processing system. The Lightbox provides a visualization platform for the real-time OCT-assisted directional atherectomy. The Lightbox consists of a cart with two monitors; a PC based processing system, software, an isolation transformer and an OCT system.

This Special 510(k) introduces an optional vessel measurement feature to the Pantheris System software in the Lightbox HS Imaging Console.

Prior to or post atherectomy procedures, physicians routinely use fluoroscopy to make visual assessments of the vessel diameter and size. This helps decide the device sizing of their choice for treatment, post atherectomy (e.g. balloon or stenting after atherectomy). The vessel measurement feature that is being introduced via this Special 510(k) submission is only intended to be used by the physicians as an optional confirmation of their initial vessel diameter/size assessment.

## Indications for Use

The Pantheris System is intended to remove plaque (atherectomy) from partially occluded vessels in the peripheral vasculature with a reference diameter of 3.0mm to 7.0mm, using OCT-assisted orientation and imaging. The system as an adjunct to fluoroscopy by providing images of vessel lumen, wall structures and vessel morphologies. The Pantheris System is NOT intended for use in the iliac, coronary, cerebral, renal or carotid vasculature.

# Comparison of Technological Characteristics with the Predicate Device

This minor modification to the Pantheris System software (cleared under K162326) does not alter the intended use or the fundamental scientific technology of the Pantheris system. There is also no change to the design, functionality, performance, materials or manufacturing processes of the Pantheris System components or accessories as part of this Special 510(k) submission. The modified software does not offer any therapy or treatment recommendations; it only serves to provide an option to the physician if they want additional information to confirm their initial vessel size assessment.

The performance testing conducted establishes that the minor software modification of including an optional measurement feature does not raise new questions of the safety and efficacy for the Pantheris System cleared under K162326.

{5}------------------------------------------------

# Non-Clinical Test Data

The minor modification to the Pantheris System software to include the optional measurement feature was successfully verified to the specifications and all acceptance criteria were met. In addition, the accuracy of the measurement feature was assessed and found to be within the specified acceptance criteria.

By design the vessel measurement feature is segregated from the active live OCT imaging software, therefore this minor modification to the software does not impact any of the Pantheris System's existing functionality.

# Conclusion

The information submitted in this premarket notification, including the successful completion of software verification and measurement accuracy testing, confirms that the minor modification to the Pantheris System software raises no new questions of safety and effectiveness and the device is substantially equivalent to the predicate device.
