Adjustable introducer valve |
| abstract |
An adjustable pnemostasis valve and method for providing a fluid seal around the periphery of endoscopic viewing scopes and instruments having a wide variety of cross-sectional sizes. The valve (8) comprises a first valve member (50) having an opening for receiving an elongated object, such as a percutaneous access device, viewing scope or an endoscopic instrument, and a flexible membrane (60) defining an aperture substantially aligned with the opening in the first valve member. A second valve member (40) is coupled to the flexible membrane for moving the membrane relative to the first valve member. As the membane is moved by the second valve member, the size of the aperture varies to that the membrane can accommodate various sized instruments. |
