Intended Use

The Single-Use Biopsy Valve provides access for endoscopic device passage and exchange, helps maintain sufflation, and minimizes leakage of biomaterial from biopsy port throughout the endoscopic procedure, and provides access for irrigation.

Device Story

The Seal Single-Use Biopsy Valve is a mechanical accessory for endoscopes. It consists of a cylindrical base, a pre-perforated cap, and a flexible internal diaphragm. The device attaches to the endoscope's working channel port. During procedures, clinicians insert surgical instruments through the cap and diaphragm; the elastomer diaphragm deforms around the instrument to create a seal, preventing fluid leakage and maintaining insufflation. The cap allows for pressure adjustment by venting gases. The device is used in clinical settings by physicians or trained staff to facilitate instrument exchange and irrigation while maintaining a closed system. It benefits patients by preventing leakage of biomaterials and maintaining necessary insufflation during endoscopic interventions.

Clinical Evidence

Bench testing only. Performance testing included pressure tests (holding 10 PSI for 1 minute) with the valve closed, with an instrument inserted, and following instrument removal. Biocompatibility testing included cytotoxicity, sensitization, intracutaneous injection, and systemic injection tests in accordance with 21 CFR Part 58 and ISO 10993-1.

Technological Characteristics

Thermoplastic elastomer construction. Mechanical diaphragm seal. Dimensions: 7.1 mm inner diameter, accommodates instruments up to 3.2 mm. Compatible with Olympus (160, 180, 190), Fujinon (530, 590, 600), and EndoChoice Fuse endoscopes. Non-sterile, single-use. No energy source or software.

Indications for Use

Indicated for use during endoscopic procedures to provide access for device passage/exchange, maintain insufflation, minimize biomaterial leakage from the biopsy port, and provide access for irrigation.

#### 5. Intended Use:

The Single-Use Biopsy Valve provides access for endoscopic device passage and exchange, helps maintain sufflation, and minimizes leakage of biomaterial from biopsy port throughout the endoscopic procedure, and provides access for irrigation.

#### 6. Device Description:

The Seal "Single-Use Biopsy valve is provided non-sterile, and is composed of a cylindrical base and a connected cap. The Single-Use Biopsy Valve provides sealable access via the working channel port of an endoscope for surgical instruments. The valve consists of an attached cap and valve body with a circular opening. The cap is pre-perforated, and ensures instrument access and removal is tight and leak-free.

{4}------------------------------------------------

The valve is designed with a hollow body with a distal end that releasably attaches to the inlet port of the working channel. The valve body provides a flexible diaphragm seal that separates the body into a proximal chamber and distal chamber. The distal chamber secures onto the endoscope, while the proximal chamber secures the cap. Instruments are inserted through the cap and chambers, through the diaphragm seal, and into the endoscope. The diaphragm seal is configured such that a seal is formed due to deformation of the elastomer around an instrument when it is inserted through the opening, preventing fluids from passing through the biopsy valve.

The cap serves two primary functions. One function of the cap is to provide an additional seal around surgical instruments to prevent leakage. The second function is to allow modification of pressure during insufflation by opening the cap, allowing gasses to flow from the endoscope, and out of the biopsy valve.

# 7. Substantial Equivalence:

The device submitted for review is a modification of the Biopsy Valve (K133734). Changes to the device include a modification in material. Both the modified and unmodified device is composed of thermoplastic elastomers. The modified device also has a reduction in overall height of the biopsy valve to provide an improved fit between the cap and body, as well as the valve to the instrument port.

The modified device is identical in terms of intended use, operating principle, performance, technology, energy used, and packaging.

# 8. Non-Clinical Testing:

The modified device has undergone both bench testing of performance and laboratory biocompatibility testing for cytotoxicity, sensitization, intracutaneous injection test, and system injection test, in accordance with 21 CFR, Part 58. The modified Single-Use Biopsy Valve results in no safety or efficacy concerns regarding biocompatibility or performance. Likewise, in conformance with 21 CFR 807.92(b)(3), the modified device performs as well as the predicate in all testing performed.

## 9. Conclusion:

The modified Single-Use Biopsy Valve is substantially equivalent to the unmodified predicate device listed above in performance, technical characteristics, biocompatibility, and intended use.
