The Seal Single Use Biopsy Valve is intended to provide access for endoscopic device passage and exchange, help maintain insufflation, minimize leakage of biomaterial from the biopsy port throughout the endoscopic procedure, and provide 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 Seal™ 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 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.
