IV catheter with in-line valve and methods related thereto
First Claim
1. An in-line valve device comprising:
- a housing including a proximal housing portion and a distal housing portion collectively defining an internal chamber, the proximal housing portion including a seating surface; and
a seal member disposed within the chamber and defining an inner cavity, the seal member including;
a proximal end with a sealing portion configured and dimensioned for engagement with the seating surface of the proximal housing portion to inhibit fluid communication through the housing;
a plurality of raised sections extending proximally from the sealing portion;
at least one window in communication with the inner cavity and being disposed distally of the sealing portion and the plurality of raised sections; and
at least one channel extending between the plurality of raised sections, wherein the plurality of raised sections and the at least one channel cooperate such that distal displacement of the sealing portion of the seal member from the seating surface of the proximal housing portion establishes at least one flow path about the seal member through the at least one window, and into the inner cavity of the seal member to permit fluid to flow through the housing.

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.

14. An in-line valve device comprising:
-
a housing defining an internal chamber, the housing including a proximal housing portion and a distal housing portion; and a seal member disposed within the chamber and including; a proximal end having a sealing portion configured and dimensioned to sealingly engage the proximal housing portion to inhibit fluid flow through the housing, the seal member defining an inner cavity; and at least one window in communication with the inner cavity and being disposed distally of the sealing portion of the seal member, whereby distal displacement of the sealing portion of the seal member from the proximal housing portion causes fluid to flow about the seal member, through the at least one window, and into the inner cavity to permit fluid communication through the housing. - View Dependent Claims (15, 16, 17, 18)
