A housing having a channel is provided with a slotted, elastomeric valve body dividing the channel. The slotted valve body is biased in the closed position by a metal spring. If the valve body\s material loses resiliency, the spring guarantees that the valve takes its closed position, even if the valve body is kept in the opened state for a considerable span of time by a steel cannula inserted through the valve body.

A valve for permanent venous cannulas or catheter insertion means, comprising: a housing having a longitudinally extending channel, an elastomeric valve body disposed in the channel and having a plurality of slots dividing the valve body into a plurality of segments, the valve body being alterable between a closed position in which the spacing between the segments is substantially minimized and an open position in which the spacing between the segments is relatively increased, insertion means for pushing the valve body into the open position, and a spring for biasing the valve body in the closed position.
