Indications for Use
The APA Oxy Blade™ is a multi-functional, single-use, disposable larynoscope blade intended to assist in direct and indirect laryngoscopy and to facilitate and aid in tracheal intubation in routine and difficult airways in adult patients. The APA Oxy Blade™ incorporates an oxygen tube adaptor and tubing to provide supplemental oxygen to the patient while undergoing endotracheal intubation.
Device Story
The APA Oxy Blade is a single-use, disposable MacIntosh-style laryngoscope blade designed for use with the Venner Medical APA Video Laryngoscope. It features an integrated oxygen tube adaptor and tubing to deliver supplemental oxygen to the patient during intubation. The device is operated by healthcare professionals trained in intubation within clinical environments. By lifting or displacing the epiglottis, the blade exposes the laryngeal inlet to facilitate endotracheal tube placement while simultaneously providing oxygenation. This dual-functionality aids in airway management, particularly in difficult airway scenarios, by maintaining patient oxygen levels during the intubation process.
Clinical Evidence
Bench testing only. No clinical data provided. Testing included packaging integrity (visual inspection, seal strength, dye penetration), biocompatibility (ISO 10993-5, -10, -11), and performance testing (dimensional, anti-fog, flow rate >15 L/min, and mechanical integrity/air-leak testing).
Technological Characteristics
Curved MacIntosh-style rigid laryngoscope blade. Materials: Polycarbonate (blade), Polyvinylchloride (tubing). Dimensions: MAC 3 (12.2 x 3.8 x 3.5 cm), MAC 4 (15.3 x 3.8 x 3.6 cm). Non-sterile, single-use. Integrates oxygen tube adaptor and tubing for supplemental oxygen delivery. Complies with ISO 10993 for biocompatibility.
Indications for Use
Indicated for adult patients undergoing endotracheal intubation who may require supplemental oxygen during the procedure, including those with routine or difficult airways.
Regulatory Classification
Identification

#### 3 PREDICATE DEVICE
The predicate devices are as follows:
- . Primary Predicate- Venner Medical APA MAC Blade, a class I, 510(k) exempt device
- Secondary Predicate- Vyaire Medical Airlife Oxygen Supply Tubing, a class I, 510(k) exempt device
Two predicate devices were selected in accordance with Section IV.C.1 of the guidance document entitled "The 510(k) Program: Evaluating Substantial Equivalence in Premarket Notifications [510(k)] - Guidance for Industry and Food and Drug Administration Staff" dated July 28, 2014.
#### DEVICE DESCRIPTION ব
The APA Oxy Blade is a laryngoscope blade intended to be used with the Venner Medical APA™ Video Laryngoscope. The APA Oxy Blade is a standard MacIntosh laryngoscope blade with the addition of an oxygen tube adaptor/holder and tubing to provide supplemental oxygen to the patient when using the Venner APA Video Laryngoscope. The Venner APA Video Laryngoscope, like other rigid laryngoscopes, provides a clear view of the upper airway (trachea/airway) and aids in the placement of an endotracheal tube for intubation.
#### INDICATIONS FOR USE ഗ
Below is the indication for use for the APA Oxy Blade.
The APA Oxy Blade™ is a multi-functional, single-use, disposable laryngoscope blade intended to assist in direct and indirect laryngoscopy and to facilitate and aid in tracheal intubation in routine and difficult airways in adult patients. The APA Oxy Blade™ incorporates an oxygen tube adaptor and tubing to provide supplemental oxygen to the patient while undergoing endotracheal intubation.

### COMPARISON OF THE INDICATION FOR USE AND INTENDED USE 6 BETWEEN THE APA OXY BLADE AND THE PREDICATE DEVICES
The APA Oxy Blade and the predicate APA MAC Blade share the same intended use, including the same purpose, function, conditions of use, users, target patient populations, and patient contact although there are slight variations in the indication for use statements (see table). The APA Oxy Blade and the Vyaire Medical Airlife Oxygen Supply Tubing device also share the same intended use, including the same purpose, function, conditions of use, users, target patient populations and patient contact. An indication for use statement was not available for the Vyaire Medical Airlife Oxygen Supply Tubing, likely reflecting the fact that the intended use and use of this simple, class I. 510(k) exempt device is commonly known and exempt from the requirements for adequate directions for use (21 CFR 801.116). Notwithstanding this, it clear that the APA Oxy Blade and the Vyaire Medical Airlife Oxygen Supply Tubing share the same intended use of oxygen delivery to patients.

### COMPARISON OF THE TECHNOLOGICAL CHARACTERISTICS WITH THE 7 PREDICATE DEVICE
The APA Oxy Blade and the predicate device, the APA MAC Blade, share many of the same technological characteristics (see Table 2). Both systems are curved rigid laryngoscope blades, referred to as the MacIntosh design. Both are used to assist in endotracheal intubation by lifting or displacing the epiglottis, and to allow for visualization of the larynx. Both share the same dimensions and materials. Both are provided non-sterile for single-patient use and have the same tissue contact.

#### PERFORMANCE DATA 8
This 510(k) notification provided performance data to establish the substantial equivalence of the APA Oxy Blade.
Packaging Integrity: The results from testing were provided to demonstrate the suitability and integrity of the packaging materials to protect the APA Oxy Blade. Packaging was assessed by visual inspections, pouch seal strength and the dye penetration testing. Devices were assessed by visual inspection and functional tests; all devices and pouches passed the tests. The packaging is suitable for its use.
Biocompatibility: Biocompatibility evaluation has been performed to show the device materials are safe, biocompatible and suitable for their intended use. Both ISO 10993 and FDA Guidance "Use of International Standard ISO 10993, Biological Evaluation of Medical Devices Part 1: Evaluation and Testing within a Risk Management Process" have been taken into account to evaluate the biocompatibility of the device materials. The following biocompatibility studies were successfully completed with the APA Oxy Blade and/or
{8}------------------------------------------------
extracts thereof. In the completed studies, the materials were observed to be non-toxic, nonirritating and non-sensitizing according to the study protocols.
| Test Performed | Test Method | Test Results |

Table 4. Summary of the Biocompatibility Tests and Results
Performance Testing: Performance testing was performed to characterize the APA Oxy Blade, including dimensional, mechanical and functional testing.
- Dimensional Specifications: The APA Oxy Blade met its dimensional specifications in both sizes.
- . Functional Testing: Functional testing included anti-fog testing and flow rate testing using standardized test methods and prospectively identified acceptance criteria. All blades successfully passed the anti-fog test with no fogging observed. All devices successfully passed the flow test and met the acceptance criterion of > 15 L/min.
- . Mechanical Testing: The mechanical integrity of the APA Oxy Blade was evaluated in three separate tests to confirm the mechanical integrity of the connections of the various components. The tests included: diffuser and tube pull test, tube coupling and tube pull test, and simulation tensile test (blade to adaptor to diffuser). In addition, air-leak testing was performed to evaluate the connection between the blade and the tubing. Standardized test methods and prospectively identified acceptance criteria were utilized. All devices successfully met the acceptance criteria for mechanical testing.
#### 9 CONCLUSIONS.
Based on the comparison, biocompatibility testing, and performance testing, it has demonstrated that the subject device is substantially equivalent to the proposed predicates and does not raise different questions of safety and effectiveness.
