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.

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.

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.

The provided text is a 510(k) summary for a medical device (Seal Biopsy Valve) and does not contain information about acceptance criteria for a study or the study details you are asking for. It focuses on demonstrating substantial equivalence to a predicate device.

Therefore, I cannot provide the requested information. The document details administrative information, the intended use of the device, its description, and a comparison to a predicate device to confirm substantial equivalence, rather than a performance study with acceptance criteria.
