Cannulation systems and methods

Abstract

One aspect of the invention provides a system including: a cannula and a valve. The valve includes: a first port coupled to the cannula; a second port adapted and configured for coupling to tubing; a third port comprising a resilient pierceable seal; and a central cylindrical plug received between the first port, the second port, and the third port. The central plug includes a through-channel adapted and configured to selectively couple two of the ports. In a first position, the first port, the third port, and the through-channel are coupled such that a dilator can pass: from outside the rotary valve; through the pierceable seal; through the first port; and out a distal end of the cannula. In a second position, the first port and the second are port are fluidically coupled.
