ABSTRACT:
The invention provides an intravascular placement apparatus adapted for operative association with an introducer needle. The apparatus provides a cannula having a connector hub at its remote end, a self-sealing septum disposed across the internal lumen of the cannula whereby the cannula can be positioned by co-operation with the introducer needle, and a blunt hollow adaptor adapted to penetrate a channel in the septum. According to the invention, the self-sealing septum is formed from a resilient material which ages rapidly after forming to a point where its resilience is not significantly further affected by time. Preferably the channel is formed in situ in the septum when the septum has aged for a predetermined period.
