Abstract
A medical valve has an interior flow path having a volume that is substantially the same when in either the closed mode (when the valve is closed) or the open mode (when the valve is open). To those ends, the medical valve has a housing forming an interior, and a valve mechanism (within the interior) having a substantially rigid translating member with a bore. The interior of the housing has a flow path that includes at least a portion of the bore of the translating member. As noted above, the open mode volume is substantially equal to the closed mode volume.
