IV catheter with in-line valve and methods related thereto
First Claim
1. An in-line valve device comprising:
- a housing that includes a proximal portion, a distal portion and a chamber therein extending between the proximal and distal portions, the proximal portion including a proximal opening that is fluidly coupled to the chamber;
a tubular member that is coupled to the housing distal portion such that a lumen thereof is fluidly coupled to the chamber;
a seal member that is disposed within the chamber to seal the proximal opening from the chamber, the proximal opening being selectively fluidly coupled to the chamber by moving a sealing portion of the seal member out of engagement with the proximal portion of the housing; and
a securing member positioned to secure a distal end of the seal member to the housing proximal portion such that the seal member is compressibly retained between a proximal end of the chamber and the securing member.

Abstract
Featured is a vascular access device such as an IV catheter device including a housing, a tubular member and a seal member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal portions. The tubular member is coupled to the housing distal portion so it is fluidly coupled to the chamber. The seal member is disposed within the chamber and the securing mechanism secures the seal member distal end to the housing proximal portion so the seal member is sealingly and compressibly retained between a chamber proximal end and the securing mechanism. Such a seal member also is constituted so a portion of the seal member moves axially responsive to an axial force applied to the proximal end.

13. A method for assembling an in-line IV catheter device comprising the steps of:
-
providing a proximal housing portion defining an internal cavity, the proximal housing portion having a proximal end and a distal end;
providing a distal housing portion defining an internal cavity, the distal housing portion having a proximal end and a distal end;
providing a seal member having a proximal end, a distal end, and including a septum;
positioning the seal member in the internal cavity of the proximal housing portion;
providing a needle having a sharpened distal end and a proximal end;
inserting the proximal end of the needle through the septum of the seal member such that the proximal end of the needle projects from the proximal end of the seal member; and
securing the proximal housing portion to the distal housing portion such that the internal cavities of the proximal and distal housing portions define a chamber. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
