The device description focuses on electrosurgical technology (bipolar, high frequency, radiofrequency) for tissue resection, ablation, and hemostasis. There is no mention of AI or ML in the intended use, device description, or performance studies. The control mechanisms are described as integrated finger switches or an optional foot pedal, and the system utilizes software for controlling modes and levels, but this does not inherently indicate AI/ML.
Yes
The device is indicated for resection, ablation, and hemostasis in arthroscopic and orthopedic procedures, which are therapeutic interventions.
No
The device is an electrosurgical device for resection, ablation, and hemostasis of soft tissue and blood vessels, which are interventional/therapeutic actions, not diagnostic ones.
No
The device description clearly details a physical electrosurgical wand with a handle, shaft, integrated cable, suction tubing, and finger switches. It also mentions connecting to a controller (RF generator) and hospital wall suction, all of which are hardware components. While the controller has incorporated software, the device itself is a physical instrument.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for the "resection and ablation of soft tissue, and hemostasis of blood vessels" in various arthroscopic and orthopedic procedures. This describes a surgical intervention performed directly on the patient's body.
- Device Description: The description details a bipolar, high-frequency electrosurgical device used for tissue manipulation and coagulation during surgery. It involves a handle, shaft, and connections to a controller and suction, all indicative of a surgical tool.
- Lack of In Vitro Activity: An IVD is designed to examine specimens (like blood, urine, or tissue samples) outside of the body to provide information about a patient's health. This device does not interact with patient specimens in this way. It is used in vivo (within the living body).
The device is a surgical instrument used for therapeutic purposes during procedures, not for diagnostic testing of samples.

Device Description
7.4.1 Ambient HipVac 50 Wand with Integrated Finger Switches
The Ambient HipVac 50 Wand is a bipolar, high frequency (HF) electrosurgical device designed for resection and ablation of soft tissue, and hemostasis of blood vessels less than 1 mm (via coagulation) in the indicated arthroscopic and orthopedic procedures (K161481).
The Ambient HipVac 50 Wand consist of a handle, shaft, integrated cable, and suction tubing. The integrated cable and suction tubing are attached to the proximal end of the handle and connect to the Controller and hospital wall suction, respectively. The plastic molded handle includes three integrated finger switches (IFS) used to activate and adjust the Coblation (ablation) and Coagulation modes: CUT (ablation), COAG (coagulation), and set point adjustment. The Ambient feature provides accurate (± 3° C) real-time temperature monitoring of the circulating irrigating fluid between 20°C and includes a user adjustable alarm set point. The Wand is designed for use up to 15 minutes of cumulative active ablation and is currently cleared to be used with ArthroCare System 12000 (QUANTUM II). Alternately, the surgeon can control these functions with the optional foot pedal. A representative image of the Ambient HipVac 50 Wand is provided (Figure 1).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
For the non-clinical performance testing, the RF20000 COBLATION system was selected as the representative model for the WEREWOLF COBLATION Systems. Hardware and 18-pin software functionality (cleared via K161481) is identical across all controllers (RF20000, WEREWOLF, WEREWOLF+), therefore the non-clinical testing results are representative of the Ambient HipVac 50 wand with the WEREWOLF COBLATION system (K192027) and WEREWOLF+ COBLATION System (K210423).
Functional tests included:
- Coagulation testing
- Ablation life (at 1X, 2X, 3X life)
- Ambient accuracy
- Finger switch functionality
- Shaft temperature
- Suction tube temperature
Because all required system level testing was previously conducted (cleared via K162074) and no changes have been made to impact device or system level requirements, the non-clinical testing conducted for this submission verified the RF20000 COBLATION System supports the wand specific requirements of the Ambient HipVac 50 wand; results are representative of the Ambient HipVac 50 wand with the WEREWOLF COBLATION system (K192027) and WEREWOLF+ COBLATION System (K210423) based on the rationale above.
Pre-clinical bench testing (ex vivo testing) was conducted on the predicate (Ambient HipVac 50 Wand with QUANTUM II) and the representative subject (Ambient HipVac 50 Wand with RF20000 COBLATION System). Thermal effect width, ablation depth (amount of tissue removed) and thermal effect depth was measured in tissue models representing bovine myocardium (muscle), cartilage, meniscus, and tendon at the minimum, default, and maximum ablation set points. Evidence obtained from preclinical bench testing (ex vivo) demonstrated that the Ambient HipVac 50 with RF20000 COBLATION System performs substantially equivalent to the predicate, Ambient HipVac 50 with QUANTUM 2. Since hardware and 18-pin functionality is identical across WEREWOLF COBLATION Systems (RF20000, WEREWOLF, WEREWOLF+), the pre-clinical testing results are representative of the Ambient HipVac 50 wand with the WEREWOLF COBLATION system (K192027) and WEREWOLF+ COBLATION System (K210423) and support substantial equivalence to the predicate.
A comparison of the peak temperature of the electrode of the subject Ambient HipVac 50 wand in conjunction with the predicate QUANTUM II and representative subject RF20000 COBLATION system was conducted during ablation at the maximum set point. The data was measured using a Neoptix T1 fiber optic temperature probe (model T1S-02-W05-PT05) using a beef heart tissue model. Both controllers with the Ambient HipVac 50 wand were activated directly over the temperature probe for ten (10) seconds at maximum ablation setpoint (9) with auxiliary suction, as required by the device IFU. The maximum temperatures recorded using both controllers were similar and support evidence of substantial equivalence. Since hardware and 18-pin functionality is identical across WEREWOLF COBLATION Systems (RF20000, WEREWOLF, WEREWOLF+), the additional testing results are representative of the Ambient HipVac 50 wand with the WEREWOLF COBLATION system (K192027) and WEREWOLF+COBLATION System (K210423) and support substantial equivalence to the predicate.

arthroscopic, orthopedic (cleared via K162074), otorhinolaryngology (ENT) procedures (cleared via K192074), and hemostasis (via coagulation) of soft tissue and bone in orthopedic procedures (cleared via K210423). The WEREWOLF+ COBLATION controller has the same hardware as the RF20000 (K162074) and WEREWOLF Coblation System (K192027); the software has been updated to increase functionality per the additional indications: hemostasis (via coagulation) of soft tissue and bone in orthopedic procedures. There have been no changes to the 18-pin wand functionality cleared in K162074.
The WEREWOLF+ controller is an enclosed unit with incorporated software that runs both the delivery of radiofrequency energy as well as a Graphical User Interface which the user can control various modes, levels, volume, etc. Ports for connecting the compatible Wands and the Foot Control are located on the front panel. An optional wireless Foot Control can be installed. The Controller also incorporates a peristaltic Integrated Fluid Control Module, which provides dynamic control of saline flow (inflow or outflow) to or from the surgical site. The system offers five distinct Modes of Operation (cleared via K162074) for arthroscopic and orthopedic procedures: Hi (Ablation), Med (Ablation), Lo (Ablation), Vac (Vacuum), and COAG (Hemostasis), and four modes for ENT procedures (cleared via K192027), and one mode (COAG) for hemostasis (via coagulation) of soft tissue and bone in orthopedic procedures (cleared via K210423).
