Intended Use
The Sinusway Dilation System is intended to access and treat the frontal, maxillary and sphenoid sinuses in sinus procedures in adults using a trans-nasal approach, by dilation and displacement of the anatomic structures along the sinus drainage pathways.
Device Description
Sinusway Dilation System combines the tissue expansion effect of balloon dilation with the features of a curved sinus seeker, and by that allows the user to track the dilation device into the sinus drainage pathways. The shape of the distal end of the dilation system can be changed by inserting pre-shaped seekers into it. The system includes: 1. A Dilation Kit (Single use, provided sterile) consists of the following components: a. A Dilation Device includes an inflatable balloon at its distal end and connects to the inflation device at its proximal end. b. Three interchangeable pre-shaped Seekers (also referred to as stylets). c. An Inflation Device connects to the dilation device and inflates it while providing visual and tactile pressure indication. All Dilation Kit components are disposed of at the end of the procedure. 2. A Holder (re-processible and auto-clavable) - holds the components of the Dilation Kit in place and locks them, allowing the user to operate the dilation tool.

No
The device description and performance studies focus on mechanical and material properties, with no mention of AI/ML algorithms or data processing.

Yes

The device is intended to treat the frontal, maxillary, and sphenoid sinuses in adults by dilation and displacement of anatomic structures, which constitutes a therapeutic action.

No
The device is described as a "Dilation System" intended to "access and treat" sinuses by "dilation and displacement of the anatomic structures." Its function is therapeutic, not diagnostic.

No

The device description clearly outlines multiple hardware components including a Dilation Kit (dilation device with balloon, seekers, inflation device) and a Holder. The performance studies also focus on hardware-related testing like biocompatibility, sterilization, and bench testing of physical attributes.

No, 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) to provide information about a person's health. This testing is done outside of the body (in vitro).
  • Sinusway Dilation System Function: The Sinusway Dilation System is a surgical tool used directly within the body (in vivo) to physically access and treat the sinuses by dilation and displacement of anatomical structures. It does not analyze or test any bodily specimens.

The description clearly indicates a surgical instrument used for a therapeutic procedure, not a diagnostic test performed on a sample.

    • b. Three interchangeable pre-shaped Seekers (also referred to as stylets).
    • c. An Inflation Device connects to the dilation device and inflates it while providing visual and tactile pressure indication.
    • All Dilation Kit components are disposed of at the end of the procedure.
    1. A Holder (re-processible and auto-clavable) - holds the components of the Dilation Kit in place and locks them, allowing the user to operate the dilation tool.

V. INDICATIONS FOR USE

Sinusway Dilation System is intended to access and treat the frontal, maxillary and sphenoid sinuses in sinus procedures in adults using the trans-nasal approach, by dilation and displacement of the anatomic structures along the sinus drainage pathways.

VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The Sinusway Dilation System has the same intended use and indications for use as the Entellus predicate device. Sinusway Dilation System, same as the predicate device, use balloon dilation technology to access and treat the target anatomy. Both balloons are positioned over a rigid pre-shaped seeker and are manually inflated with saline until the desired result is achieved. The Sinusway Dilation System and Entellus predicate device principles of operation are identical. Both devices are advanced into the nasal and sinus anatomy under direct endoscopic visualization and treat the anatomy by dilating and displacing anatomic structures along the sinus drainage pathways. Both devices are used through a trans-nasal approach.

Similar tests and tests methods performed in accordance with the same standards were used in both Sinusway Dilation System and the predicate device to validate the design. The testing results showed that the minor differences in device characteristics and principles of operation between the subject device and predicate device do not raise any new questions of safety or effectiveness.
