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 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.

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.

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. - View Dependent Claims (19, 20)

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. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
