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.

What is claimed is: 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 to create a flow oath about the seal member; 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. 2. The in-line device of claim 1, wherein the securing member is an annular ring. 3. The in-line device of claim 2, further including a groove formed in the housing proximal portion dimensioned to receive and axially retain the annular ring. 4. The in-line device of claim 1, wherein the securing member includes a raised rib formed about an inner circumference of the proximal portion of the housing. 5. The in-line device of claim 1, wherein: the seal member includes one or more through apertures extending between an inner cavity and an outside surface of the seal member; and the seal member is arranged in the housing proximal portion so that the seal member inner cavity is fluidly coupled to a portion of the chamber disposed in the housing distal portion. 6. The in-line device of claim 1, wherein the seal member includes a septum in which an introducer needle is removably received. 7. The in-line device of claim 6, wherein: the seal member includes a proximal end; a portion of the seal member proximal end includes a sealing portion for sealing engagement with at least a portion of the chamber proximal end; and the seal member septum is arranged so the septum lies in the same general axial plane as the sealing portion. 8. The in-line device of claim 6, wherein: the seal member includes a proximal end; and the seal member is configured so that the septum is spaced distally from the sealing portion. 9. The in-line device of claim 1, wherein the housing distal portion includes at least one axially extending fin extending from an inner surface of a portion of the chamber disposed within the housing distal portion. 10. The in-line device of claim 9, wherein the at least one axially extending fin is arranged so as to only contact the seal member during a high pressure fluid flow condition. 11. The in-line device of claim 10, wherein the at least one axially extending fin extends radially inward into the chamber disposed within the housing distal portion. 12. The in-line device of claim 11, wherein the at least one axially extending fin is configured, dimensioned, and positioned to inhibit inversion or folding of the seal member in response to increased pressure within the inner chamber. 13. The in-line device of claim 10, wherein the at least one axially extending tin extends inwardly into the chamber disposed within the housing distal portion in a non-radial fashion. 14. The in-line device of claim 13, wherein the at least one axially extending fin includes a plurality of axially extending fins that are spaced apart to provide an opening extending axially through the chamber disposed within the housing, the opening being configured and dimensioned to receive an introducer needle. 15. The in-line device of claim 1, wherein the housing distal portion includes a plurality of intersecting members extending from an inner surface of the chamber to define a grate including an open region configured and dimensioned to receive an introducer needle. 16. The in-line device of claim 1, wherein the flow path is defined between the seal member and the housing. 17. The in-line device of claim 1, wherein the securing member is positioned distally of the seal member. 18. A vascular access 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 to create a flow oath about the seal member; and wherein the housing distal portion includes at least one axially extending fin extending from an inner surface of a portion of the inner chamber disposed within the housing distal portion. 19. The vascular access device of claim 18, wherein the at least one axially extending fin is arranged so as to only contact the seal member during a high pressure fluid flow condition. 20. The in-line device of claim 18, wherein the flow path is defined between the seal member and the housing. 21. 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 disposed within the chamber and being movable between a first position sealingly engaged to a region of the housing and a second position to permit fluid flow through the housing, and wherein the seal member includes a septum configured to removably receive an introducer needle; and stop structure positioned within the housing, the stop structure being spaced apart from the seal member when the seal member is in the first position and configured, dimensioned, and positioned for engagement with the seal member when the seal member is in the second position to inhibit continued axial movement of the seal member, the seal member being moved from the first position to the second position upon realization of a predetermined level of pressure within the housing while maintaining fluid flow through the housing. 22. The in-line device of claim 21, wherein the stop structure includes at least one axially extending fin extending inwardly from an inner surface of the housing. 23. The in-line device of claim 22, wherein the at least one axially extending fin is arranged so as to only contact the seal member during a high pressure fluid flow condition. 24.
