Medical valve and method of use
First Claim
1. A flexible element for use with a medical connector, comprising a proximal end, a distal end, and a flexible wall with an inner surface and an outer surface, the flexible element further defining a first region adjacent the proximal end, a second region, and a third region near the distal end, the second region being between the first and third regions, the outer surface in the first region having at least a first external cross-sectional width, the outer surface in the second region having at least a second external cross-sectional width, and the outer surface in the third region having at least a third external cross sectional width, the second external cross-sectional width being different than the first and third cross-sectional widths, the inner surface in the first region having at least a first internal cross-sectional width, the inner surface in the second region having at least a second internal cross-sectional width, the inner surface in the third region having at least a third internal cross-sectional width, the second internal cross-sectional width being different than the first and third internal cross-sectional widths, the proximal end including a cap and an orifice wherein the shape of the cap assists in closing the orifice.

Abstract
A closed system, needleless valve device includes a generally tubular body defining an internal cavity. On the proximal end of the body there is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The distal end of the body has a generally tubular skirt. The valve also includes a hollow spike having a closed tip. The spike includes at least one longitudinal 18-gauge hole located distal the tip, and is seated inside the cavity such that the tip is below the proximal end of the body. An annular support cuff is connected to the spike which seals off a portion of the cavity of the body such that an upper cavity containing the tip is defined. The valve also includes a plastic, resilient silicone seal which fills the upper cavity and opening and covers the tip of the spike so as to present a flush surface. An adaptor enables the valve to be attached to a resealable container.
