## Intended Use
To access and treat the maxillary ostia/ethmoid infundibula in patients 2 years and older, and frontal ostia/recesses and sphenoid sinus ostia in patients 12 years and older using a trans-nasal approach. The bony sinus outflow tracts are remodeled by balloon displacement of adjacent bone and paranasal sinus structures.
## Device Story
BB 8 Sinus Dilation Kit is a manual ENT surgical instrument for sinus ostia dilation. Device inputs include manual positioning by a physician using an integrated LED light fiber for transillumination-guided placement. The device features a shapeable catheter with an inflatable balloon, suction, and irrigation lines. The physician uses a bend template to shape the catheter tip for specific sinus anatomy. The balloon is manually inflated via a provided syringe to a maximum of 12 ATM to remodel bony sinus outflow tracts. Suction and irrigation capabilities allow for field clearing and visualization. Used in a clinical setting by ENT specialists, the device enables minimally invasive sinus access, potentially reducing recovery time and improving sinus drainage for patients with obstructive sinus conditions.
## Clinical Evidence
Bench testing only. No clinical data provided. Verification testing included visual, dimensional, and functional assessments (e.g., balloon burst pressure, fatigue, LED visibility, suction/irrigation rates), electrical safety, EMC, and biocompatibility testing per ISO 10993-1.
## Technological Characteristics
Manual ENT surgical instrument; shapeable catheter with inflatable balloon; integrated LED light fiber (battery-powered); suction and irrigation channels. Materials are biocompatible per ISO 10993-1. Sterilization via Ethylene Oxide (EtO). Maximum inflation pressure 12 ATM. Includes bend template and inflation syringe with pressure gauge.

#### Device Description:
The BB 8 Sinus Dilation Kit is intended to remodel or recreate the sinus outflow tract via transnasal balloon dilation. The device combines features of a curved suction tip and a sinus ostium seeker with the tissue expansion effect of balloon dilation. Since the distal end of the device is re-shapeable, one balloon can be modified to work on multiple sinuses within the same patient. The device also allows the capability to suction and irrigate the surgical field to allow for removal of bodily secretions and to keep the field of view clean for improved visualization. The device includes an LED light with light fiber to locate, illuminate within, and transilluminate across nasal and sinus structures.
In summary, the device includes the following components and accessories:
- 1. BB 8 Sinus Dilation Kit which incorporates:
- a. shapeable catheter with inflatable balloon
- b. LED light fiber
- c. irrigation line, and
- d. suction line,
- 2. Inflation syringe,
- 3. Extension line used for inflation of the balloon (and to provide irrigation, if desired), and
- 4. A bend template for shaping the catheter tip for treating various sinus anatomy
#### Indications for Use:
To access and treat the maxillary ostia/ethmoid infundibula in patients 2 years and older, and frontal ostia/recesses and sphenoid sinus ostia in patients 12 years and older using a transnasal approach. The bony sinus outflow tracts are remodeled by balloon displacement of adjacent bone and paranasal sinus structures.
#### Technological Characteristics and Performance Data (Predicate Comparison):
The device has similar intended use, indications for use, mechanism of action, and performance compared to the predicate devices.
The balloons of the EXCELENT and Entellus devices are both positioned over a shapeable catheter and are manually inflated with saline and a syringe until the desired inflation pressure (up to 12 ATM) is achieved. The subject and 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.
The intended use, indications for use, balloon dimensions, sterilization method, maximum inflation pressure, catheter type, light feature, inflation mechanism, and biocompatibility have been demonstrated as identical or similar between the subject and predicate devices.
{5}------------------------------------------------
Additionally, verification testing for the subject device is similar to the testing performed for the predicate devices and demonstrates that minor differences in the device characteristics between the subject and predicate devices do not raise any new questions of safety and efficacy. Verification testing performed for the subject device includes:
- l Visual Testing
- Visual Connection Indicators on Device Handle o
- Marker Band Location o
- I Dimensional Testing
