The summary describes a microwave ablation system with an optional navigation feature that enhances ultrasound images. There is no mention of AI or ML in the intended use, device description, or performance studies. The navigation feature appears to be based on image guidance and predicted trajectory/ablation zone display, not AI/ML-driven analysis or decision-making.
Yes
The device is intended for coagulation (ablation) of soft tissue, including nonresectable liver tumors, which directly treats a medical condition.
No
Explanation: The device is described as an "ablation system" and is intended for "coagulation (ablation) of soft tissue." Its function is to destroy tissue, not diagnose conditions. While it uses image guidance for placement, this is for therapeutic delivery, not diagnostic interpretation.
No
The device description clearly lists multiple hardware components including a generator, antenna, cable, pump, and optional accessories like a cart and footswitch. While software is mentioned for control and navigation, it is part of a larger hardware system.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue samples) to provide information for diagnosis, monitoring, or screening.
- Device Function: The Emprint™ Ablation System is used for the direct treatment of soft tissue and tumors within the body through coagulation (ablation) using microwave energy. It is an interventional device used during surgical procedures.
- Intended Use: The intended use clearly states "coagulation (ablation) of soft tissue, including partial or complete ablation of nonresectable liver tumors." This is a therapeutic action, not a diagnostic test performed on a sample outside the body.
- Device Description: The description details a microwave generator, antenna, pump, and accessories used to deliver energy to the patient's tissue. This aligns with a therapeutic device, not an IVD.
The device utilizes imaging (ultrasound) for guidance, but this is for placement of the therapeutic device, not for analyzing a biological sample.

Device Description
The Emprint™ Ablation System with Thermosphere™ Technology, Covidien's microwave ablation platform, was released for commercial distribution in the United States in April 2014.
The 510(k) Cleared Emprint™ Ablation System consists of the following components:
-
- Emprint™ Ablation Generator (2450 MHz)
-
- Emprint™ Percutaneous Antenna (sterile, single use)
-
- Emprint™ Ablation Reusable Cable
-
- Emprint™ Ablation Pump
The system also includes the following optional equipment/accessories:
- 5. Emprint™ Ablation Cart
-
- Ablation Footswitch
-
- Isolation Transformer
-
- Remote Temperature Probe (sterile, single use)
The ablation platform must be used with a standard IV bag of sterile, normal saline (not provided with the device).
In 2016 Covidien LLC made changes to improve the usability of the Emprint™ Ablation System's percutaneous antenna, by increasing the stiffness of the antenna's shaft. Like the predicate antenna approved via traditional 510(k) (K133821), the modified antenna is manufactured in 3 lengths (15, 20 and 30 cm) and is uniquely identified by catalog numbers (CA15L2, CA20L2 and CA30L2).
The Emprint™ SX Ablation Platform with Thermosphere™ Technology is a microwave ablation system with an optional navigation feature. It relies on the same principles of operation, fundamental technology, and performance characteristics as its predicate, the Emprint™ Ablation System with Thermosphere™ Technology (K133821, K163105).
The main differences between the Emprint™ SX Ablation Platform with Thermosphere™ Technology and the predicate device include software (vs. manual) control of the generator and pump, as well as the addition of an optional navigation feature. Both systems include a 2.45 GHz microwave generator, a cooling pump, and accessories. A bag/bottle of sterile fluid that connects to the antenna's tubing and to the peristaltic pump is required for proper system operation. The 510(k) Cleared Emprint™ Percutaneous Antenna (K163105) can be used with either system to create predictable, spherical ablation zones in soft tissue in percutaneous, laparoscopic, and intraoperative procedures.
The Emprint™ antenna, the applied part of the Emprint™ ablation system with Thermosphere™ Technology and Emprint™ SX ablation platform with Thermosphere™ Technology that delivers microwave energy to the patient, has a sharp, engineered ceramic tip (called "trocar") at the distal end of the device that allows a user to puncture tissue. The shaft of the disposable antenna is inserted directly into the tissue intended to be ablated. The radiating tip of the antenna shaft delivers microwave energy to the target tissue.
Modifications have been made to the Emprint™ Ablation System and Emprint™ SX Ablation Platform's IFU's and Antenna's. Updates were made to the IFU to reduce the possible trocar detachment post ablation resulting from atypical use.
Changes made to the bond curing schedule is to enhance the bond strength between the trocar and the fiberglass shaft.
Additionally, the clear non-stick heat shrink was extended further on the antennae to reduce tissue adherence post ablation.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench Verification Testing:
Testing was conducted to:
- demonstrate the modified antenna's trocar bond strength was greater than the predicate.
- confirm that the change did not impact the reliability of the device by performing thermal ablations in soft tissue during the extended use test.
- quantify and compare the frictional force between the modified antenna and the adjustable depth quide. insertion force and extraction force (ex-vivo liver tissue) of the modified antenna relative to the 510(k) cleared devices.
Key results: The modification to the antennae trocar bonding and clear non-stick heat shrink extension have improved parameters such as tensile bond strength, antenna insertion force and antenna extraction force compared to the current device (predicate) without affecting the design requirements and the essential performance of the antenna and the system as a whole.

IV. Device description
The Emprint™ Ablation System with Thermosphere™ Technology, Covidien's microwave ablation platform, was released for commercial distribution in the United States in April 2014.
The 510(k) Cleared Emprint™ Ablation System consists of the following components:
-
- Emprint™ Ablation Generator (2450 MHz)
-
- Emprint™ Percutaneous Antenna (sterile, single use)
-
- Emprint™ Ablation Reusable Cable
-
- Emprint™ Ablation Pump
The system also includes the following optional equipment/accessories:
-
- Emprint™ Ablation Cart
-
- Ablation Footswitch
-
- Isolation Transformer
-
- Remote Temperature Probe (sterile, single use)
The ablation platform must be used with a standard IV bag of sterile, normal saline (not provided with the device).
In 2016 Covidien LLC made changes to improve the usability of the Emprint™ Ablation System's percutaneous antenna, by increasing the stiffness of the antenna's shaft.

Covidien made the change to accommodate a usability-related preference, expressed by physicians. The modification was not in response to reported device malfunctions or adverse events associated with the current, more-flexible ablation antenna.
This change in stiffness enhances the antenna's usability; and has no effect on the system's essential function, performance or underlying principles of operation.
The Emprint™ SX Ablation Platform with Thermosphere™ Technology is a microwave ablation system with an optional navigation feature. It relies on the same principles of operation, fundamental technology, and performance characteristics as its predicate, the Emprint™ Ablation

The clear non-stick heat shrink was extended further on the antennae to reduce tissue adherence.
VI. Indications for use
Modifications made to the Antenna's do not alter the Indications for use (shown below) for the Emprint™ Ablation system and the Emprint™ SX ablation platform.
The Emprint™ Ablation System with Thermosphere™ Technology:
The Emprint™ Ablation System is intended for use in percutaneous, laparoscopic, endoscopic, and intraoperative coagulation (ablation) of soft tissue, including partial or complete ablation of nonresectable liver tumors.
The Emprint™ Ablation System is not intended for use in cardiac procedures.
The Emprint™ SX Ablation Platform with Thermosphere™ Technology:
The Emprint™ SX Ablation Platform with Thermosphere™ Technology is intended for use in percutaneous, laparoscopic, and intraoperative coagulation) of soft tissue, including partial or complete ablation of nonresectable liver tumors.
The Emprint™ SX Ablation Platform is not intended for use in cardiac procedures.
The system's optional, 3-D navigation feature assists in the placement of the Emprint™ SX Navigation Antenna with Thermosphere™ Technology using real-time image guidance during intraoperative and laparoscopic ablation procedures. The navigation feature enhances the output of a compatible medical ultrasound imaging system and displays an image of the antenna and its predicted trajectory on a computer monitor. The size and shape of the predicted ablation zone relative to the position of the antenna is displayed on the enhanced ultrasound image.
VII. Comparison of technological characteristics with the predicate device
The Emprint™ Ablation System with Thermosphere™ Technology and Emprint™ SX Ablation Platform with Thermosphere™ Technology current antennae (predicate device's) and the modified ablation antenna share the same underlying technology. Both devices are used to deliver microwave energy to soft tissue in a highly controlled way. Signal frequency, power and exposure time are controlled by the system's 2450 MHz generator. The design of the radiating portion of the accessory and continuous cooling of the accessory during the ablation procedure determines the shape (near spherical) and size of the resulting ablations.
The modification to the antennae trocar bonding and clear non-stick heat shrink extension have improved parameters such as tensile bond strength, antenna insertion force and antenna extraction force compared to the current device (predicate) without affecting the design requirements and the essential performance of the antenna and the system as a whole.
8
VIII. Performance data
Non-clinical performance data was provided in support of the substantial equivalence determination.
Bench Verification Testing a)
Verification testing was conducted to:(1) demonstrate the modified antenna's trocar bond strength was greater than the predicate, (2) confirm that the change did not impact the reliability of the device by performing thermal ablations in soft tissue during the extended use test. (3) quantify and compare the frictional force between the modified antenna and the adjustable depth quide. insertion force and extraction force (ex-vivo liver tissue) of the modified antenna relative to the 510(k) cleared devices.
IX. Conclusions
The modified Emprint™ Ablation System with Thermosphere™ Technology and Emprint™ SX Ablation Platform with Thermosphere™ Technology antennae are identical to the predicate device's, except for bond cure schedule change and clear non-stick heat shrink design change. The subject and predicate devices share intended use, technological characteristics, and meet identical performance requirements. The results of comprehensive verification testing raised no new questions of safety or effectiveness. The Emprint™ Ablation System with Thermosphere™ Technology and Emprint™ SX Ablation Platform with Thermosphere™ Technology Antennae (subject device) and the modified antennae are substantially equivalent.
