Valved connector
First Claim
1. A valved connector for controlling the flow of fluid, comprising:
- a connector housing having an inlet and an outlet, the inlet configured to receive a male luer fitting; and
a valve assembly having a first position that prevents fluid flow through the connector housing and a second position that permits fluid flow through the connector housing, the valve assembly biased in the first position and movable from the first position to the second position by the male luer fitting, the valve assembly comprising;
a valve element including an upper portion, a slit portion and a lower portion, the upper and lower portions having bores extending through the valve element to the slit portion, the valve element having an outer wall with a reduced outer diameter at the slit portion to create a gap between the valve element and the connector housing, wherein movement of the male luer fitting into the upper portion bore causes the slit portion to open radially by compressing the outer wall against the connector housing; and
a support disk having a hole through the center thereof, the valve element positioned on the support disk.

Abstract
A valved connector for controlling the flow of fluid having a valve assembly positioned within a connector housing having a first position wherein the valve assembly prevents fluid flow through the connector housing, and a second position wherein the valve assembly permits fluid flow through the connector housing. The valve assembly may be movable from the first position to the second position by a male luer fitting. The valve assembly is configured for multiple and repeated access and also for minimizing fluid flow restrictions. The valved connector may be designed for use with a catheter to provide for “over the guidewire” placement or replacement techniques with little or no bleed-back or air embolism.

14. A valved connector for controlling the flow of fluid, comprising:
-
a connector housing having an inlet at a proximal end and an outlet at a distal end; and a valve assembly positioned in the connector housing, the valve assembly including a valve element and a support disk, a distal end of the valve element positioned proximal of the support disk, the valve element including an upper portion, a lower portion, and a slit portion between the upper portion and the lower portion, the upper portion and the lower portion having respective bores extending through the valve element to the slit portion, the valve element having an outer wall with a reduced outer diameter at the slit portion to create a gap between the valve element and the connector housing, the valve element movable from a first position, preventing fluid flow through the connector housing, to a second position, permitting fluid flow through the connector housing, by a male luer fitting inserted through an opening in the inlet and into contact with the valve element without penetrating the slit portion. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A valved connector, comprising:
-
a connector housing having an inlet at a proximal end and an outlet at a distal end; and a valve assembly positioned in the connector housing, the valve assembly including a valve element positioned proximal of a support disk, a distal surface of the valve element in contact with a proximal surface of the support disk, the valve element having an outer wall with a reduced outer diameter at the slit portion to create a gap between the valve element and the connector housing, the valve element movable from a first closed position to a second open position by a male luer fitting inserted through an opening in the inlet and into contact with an inner surface of a bore in an upper section of the valve element such that the inner surface of the bore is moved radially toward the connector housing, the valve element including a slit through a mid-section, the slit opening when the valve element is moved to the second position to place the upper section bore in fluid communication with a bore in a lower section of the valve element.
