Intended Use
The esolution® Esophageal Retractor is indicated for use in patients undergoing percutaneous cardiac catheter ablation of atrial fibrillation to deviate the esophagus away from the ablation energy source and to reduce the risk of ablation-related esophageal injury.
Device Description
The esolution® Esophageal Retractor is a sterile mechanical deviation device for esophageal protection during cardiac ablation procedures. This device is placed in the lumen of the esophagus to reduce the likelihood of esophageal injury or a specific adverse event during cardiac ablation procedures. The device uses mechanical means to deviate the esophagus away from the source of ablation energy. The esolution® Esophageal Retractor contains two main components: an Outer Sheath, which is placed in the esophagus prior to the initiation of the therapeutic ablation procedure and a Mechanical Deflection Device that is inserted into the Outer Sheath once the Outer Sheath has been positioned in the esophagus for the indicated atrial fibrillation ablation therapeutic care. The purpose of this 510(k) is to capture the modifications made to the esolution® Esophageal Retractor required for manufacturability including changes to materials and design.

No
The device description and performance studies focus solely on the mechanical function and material properties of the esophageal retractor, with no mention of AI or ML.

No
The device is described as a "sterile mechanical deviation device for esophageal protection during cardiac ablation procedures" and its purpose is to "deviate the esophagus away from the ablation energy source and to reduce the risk of ablation-related esophageal injury" rather than directly treating a medical condition or disease. It is a protective device used during a therapeutic procedure.

No

Explanation: The device is described as a "mechanical deviation device for esophageal protection" whose purpose is to "deviate the esophagus away from the ablation energy source." It is used to prevent injury during a procedure, not to diagnose a condition.

No

The device description clearly states it is a "sterile mechanical deviation device" with physical components (Outer Sheath and Mechanical Deflection Device) that are placed in the esophagus. This indicates a hardware-based medical device, not a software-only one.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to mechanically deviate the esophagus during a cardiac ablation procedure to reduce the risk of injury. This is a therapeutic/interventional use, not a diagnostic one.
  • Device Description: The device is described as a "sterile mechanical deviation device" that is "placed in the lumen of the esophagus." It uses "mechanical means to deviate the esophagus." This description aligns with a physical medical device used during a procedure, not a device used to perform tests on samples from the body.
  • Lack of IVD Characteristics: There is no mention of:
    • Analyzing samples (blood, tissue, etc.)
    • Detecting or measuring substances in the body
    • Providing information for diagnosis, monitoring, or screening

The device's function is to physically manipulate an anatomical structure during a medical procedure. This falls under the category of a surgical or interventional device, not an in vitro diagnostic device.

Substantial Equivalence

The esolution® (Gen 2.1) has the same indications for use and similar design features as compared with the predicate device (DEN230006). The bench testing demonstrates that the performance characteristics of the esolution® (Gen 2.1) are equivalent to those of the legally marketed predicate device, and therefore supports a determination of Substantial Equivalence for the proposed indications for use. Any differences between the subject and predicate devices would not render the device NSE or raise different questions of safety and effectiveness.
