Abstract
A gasket for creating a fluid seal in a medical device includes a flexible base, a flexible hollow body, and a multi-leaflet valve. The flexible hollow body extends along an axis from a hole defined in the flexible base. The flexible hollow body is configured to have a relaxed state in which a cross section of the flexible hollow body has a first shape and a compressed state in which the cross section of the flexible hollow body has a second shape. The multi-leaflet valve is disposed in the flexible hollow body. The compressed state causes the multi-leaflet valve to close to increase (a) a first threshold force or a first threshold pressure differential needed to open the multi-leaflet valve in a distal direction and (b) a second threshold force or a second threshold pressure differential needed to open the multi-leaflet valve in a proximal direction.
