No
The B-Laser™ Atherectomy System is described as a treatment device for infra-inguinal stenoses and occlusions, performing atherectomy, which is a therapeutic procedure to remove plaque. It does not mention any functional capabilities related to diagnosis or detection.
No
The device description clearly outlines physical components including a single-use catheter with optic fibers and a blunt blade, and a laser system. This indicates it is a hardware-based medical device, not software-only.
Based on the provided information, the B-Laser™ Atherectomy System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is for the treatment of infra-inguinal stenoses and occlusions through atherectomy. This is a therapeutic procedure performed directly on the patient's body.
- Device Description: The device is a physical system (catheter and laser) designed to mechanically and energetically remove plaque from blood vessels. It is used in vivo (within the living body).
- Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The B-Laser™ System does not perform any such analysis of biological specimens.
Therefore, the B-Laser™ Atherectomy System is a therapeutic medical device, not an IVD.

Device Description
The B-Laser™ System consists of two sub-units: 1) a single use catheter ("B-Laser™ catheter"); and 2) a laser system. The B-Laser™ catheter is a single use catheter that is made of an array of optic fibers and surrounded by a circumferential blunt blade at its distal tip. The B-Laser™ catheter is connected to the laser system via its connector and transmits energy at pre-set fluence levels of 50 and 60 mJ/mm² to the occluded or narrowed artery. The B-Laser™ System must work over a commercially available 300cm 0.014" guide wire (GW) that crosses the lesion intraluminally. - For the small size catheters (i.e., 0.9mm and 1.5mm), there is a designated lumen tube for a quidewire at the center of the inner blunt blade. Please note that 0.9mm and 1.5mm catheters do not have an aspiration feature and have not been tested in ISR lesions. These devices should not be used in ISR cases.
The larger B-Laser™ catheters (i.e., 2.0mm and 2.35mm) have an eccentric guidewire lumen, and include additional features consisting of an aspiration feature (both catheters) and an "offcenter" feature (2.35mm only). The aspiration feature is intended for debris and thrombus collection and removal from the vessel during the atherectomy procedure.
The "off-center" feature is included in the 2.35 mm catheter only and is designed to facilitate debulking of lesions in blood vessels beyond the catheter's diameter.

Safety measures were: vessel injuries (gross pathology and histopathology) following activation of the B-Laser™ at highest energy, thrombogenicity, presence of distal embolization at all anatomical levels, general health and general gross pathology.
Clinical Testing
Clinical evaluation of the device in the intended population was performed in a prospective, single-arm, multi-center, open-label, non-randomized clinical study in 50 subjects in Europe, as well as in a pivotal, prospective, single-arm, multi-center, open-label, non-randomized IDE clinical study in 97-subjects in US and Europe.
In the pilot study, the results presented 100% success in crossing the target lesions (52/52 lesions in 49 subjects) and residual stenosis reduction of 35.04% on average as determined by retrospective evaluation by independent Corelab. There were no device related perioperative clinically significant adverse events (0%), and there were no major adverse events (MAE) (0%) to 30-days and 6-months post procedure, and only 2 cases (4.3%) of MAE (one target lesion revascularization, at 384 days post procedure and a second TLR was a planned revascularization with surgical by-pass due to recurrent symptoms of chronic ischemia after the completion of 1 year follow-up) amongst 46 subjects that completed the 1 year post procedure follow-up. Further, there were no device related adverse events. Eighteen serious adverse events (SAEs) were reported during the course of the study in 14 subjects that were unrelated to the subject B-Laser™ catheter.
In the pivotal study, the safety and effectiveness primary endpoints were achieved. There was only 1 MAE at 30 days (death, not related to the device) out of 97 subjects (1.03%) and the average reduction of residual stenosis was 33.6% (14.2% SD) out of the 95 evaluable subjects(or 107 evaluable lesions). There were only 11 type A and 5 type B dissections, and 1 case of transient spasm and 1 case of transient staining after the use of the device, none of which require intervention, with regards to the secondary safety endpoint. No other device related perioperative complications were noted or reported.

Intended Use / Indications for Use
The B-Laser™ Atherectomy System is intended for use in the treatment, including atherectomy, of infra-inguinal stenoses and occlusions, including in-stent restenosis (ISR).
Device Description
The B-Laser™ System consists of two sub-units: 1) a single use catheter ("B-Laser™ catheter"); and 2) a laser system. The B-Laser™ catheter is a single use catheter that is made of an array of optic fibers and surrounded by a circumferential blunt blade at its distal tip. The B-Laser™ catheter is connected to the laser system via its connector and transmits energy at pre-set fluence levels of 50 and 60 mJ/mm² to the occluded or narrowed artery. The B-Laser™ System must work over a commercially available 300cm 0.014" guide wire (GW) that crosses

the lesion intraluminally. - For the small size catheters (i.e., 0.9mm and 1.5mm), there is a designated lumen tube for a quidewire at the center of the inner blunt blade. Please note that 0.9mm and 1.5mm catheters do not have an aspiration feature and have not been tested in ISR lesions. These devices should not be used in ISR cases.
The larger B-Laser™ catheters (i.e., 2.0mm and 2.35mm) have an eccentric guidewire lumen, and include additional features consisting of an aspiration feature (both catheters) and an "offcenter" feature (2.35mm only). The aspiration feature is intended for debris and thrombus collection and removal from the vessel during the atherectomy procedure.
The "off-center" feature is included in the 2.35 mm catheter only and is designed to facilitate debulking of lesions in blood vessels beyond the catheter's diameter.
Comparison of Technological Characteristics
The B-Laser™ System has similar technological characteristics as its predicate devices. Both the B-Laser™ System and the primary predicate device have similar components. Both the subject and primary predicate device include two sub-units consisting of a catheter component and an external laser system. The external laser systems for both devices connect to the catheter and transmit laser pulses through the catheter to ablate the target lesion. Both the B-Laser™ System and the primary predicate transmit laser at similar fluence levels to the lesion (50 and 60mJ/mm² for the B-Laser™ System versus 30-80 mJ/mm² for the primary predicate). lt should be noted that the fluence levels for the B-Laser™ System are within the fluence levels cleared for the primary predicate device. Although the specific wavelengths and pulse repetition rates differ, these minor differences do not adversely impact performance, as confirmed in performance testing.
Both the B-Laser™ System and its primary predicate are intended for similar vessels of the infrainquinal area at a diameter range that starts at 1.4 mm. Further, both the subject and the primary predicate have similar catheter diameters that are compatible with sheath sizes of 4F-7F for the subject device and 4F-8F for the primary predicate. The B-Laser™ System and primary predicate have similar working lengths (125 to 150 cm for the B-Laser™ System versus 112-150 cm for the primary predicate). In addition, the subject device and the primary and reference devices are over-the-wire catheters that are compatible with 0.014" quidewires, are sterilized using ethylene oxide, and are for single use only.
The B-Laser™ System and the reference device, Phoenix® Atherectomy System (K132682), have similar technological characteristics. They are both designed for atherectomy of the peripheral vasculature. Further, both the 2.0 mm and 2.35 mm catheters sizes of the B-Laser™ System and the reference device have debris collection and removal mechanisms. Although the subject device uses vacuum aspiration whereas the reference device continuously collects and removes the excised debris by mechanical conveyance using an Archimedes Screw, this difference does not raise new questions of substantial equivalence. Lastly, both the subject device and the reference device are indifferent to the presence of contrast media.
Therefore, the subject B-Laser™ System has very similar technological characteristics as its predicates.

In the pilot study, the results presented 100% success in crossing the target lesions (52/52 lesions in 49 subjects) and residual stenosis reduction of 35.04% on average as determined by retrospective evaluation by independent Corelab. There were no device related perioperative clinically significant adverse events (0%), and there were no major adverse events (MAE) (0%) to 30-days and 6-months post procedure, and only 2 cases (4.3%) of MAE (one target lesion revascularization, at 384 days post procedure and a second TLR was a planned revascularization with surgical by-pass due to recurrent symptoms of chronic ischemia after the completion of 1 year follow-up) amongst 46 subjects that completed the 1 year post procedure follow-up.

Substantial Equivalence
The B-Laser™ System has the same intended use and very similar indications for use, technological characteristics, and principles of operation as its predicate devices. Performance testing, including functional testing, simulated use testing, in vivo GLP testing in animal models, and clinical testing demonstrated it to be at least as safe and as effective as the predicate and that the minor differences in technology do not raise new questions of safety or effectiveness. Thus, the B-Laser™ System is substantially equivalent to the predicate devices.
