Medical valve and methods fuse

A method of transferring fluid through a medical valve, said valve having a body with an internal cavity having a proximal end and a distal end, said proximal end having an opening sufficiently large to receive a delivery end of a medical implement which transfers fluid through said delivery end, a spike within said cavity, said spike having a spike tip at the proximal end thereof, a first hole distal said spike tip and a second hole distal said first hole for permitting fluid to flow through said spike, and a resilient seal within said cavity of said body between said body and said spike, said seal in contact with said spike in at least two spaced-apart points along said spike proximal said first hole to prevent flow of the fluid through said valve when said seal is in a decompressed state, said method comprising the steps of:

• (a) inserting a tip of a medical implement into said opening in the proximal end of said body;
• (b) compressing said seal in the distal direction by applying a force to the medical implement;
• (c) placing said hole and said medical implement in fluid communication;
• (d) transferring the fluid through said medical valve;
• (e) removing said medical implement from said opening in the proximal end of said body;
• and
• (f) permitting said seal to contact said spike proximal said first hole, thereby preventing the flow of the fluid through said valve.
