Some embodiments relate to a luer connector comprising a housing having a hollow bore therethrough, a first end, and a second end, a male luer tip supported by the housing configured to rotate with respect to the housing, the luer tip having a first open end and a passageway through the luer tip in fluid communication with the first open end, and a substantially rigid internal member extending into the passageway of the luer tip toward the first open end of the luer tip. In some embodiments, at least one of the luer tip and the internal member can be axially moveable between a first closed position and a second open position relative to the other of the luer tip and the internal member. Further, the luer tip and the internal member can cooperate such that rotation of the luer tip in a first direction relative to the housing increases an axial displacement between the first open end of the luer tip and an end portion of the internal member.

1. A closed male luer connector comprising: a housing having a hollow bore, a first end, and a second end;a male luer tip of the closed male luer connector supported by the housing and configured to rotate with respect to the housing, the male luer tip having a first open end and a passageway throug
1. A closed male luer connector comprising: a housing having a hollow bore, a first end, and a second end;a male luer tip of the closed male luer connector supported by the housing and configured to rotate with respect to the housing, the male luer tip having a first open end and a passageway through the male luer tip in fluid communication with the first open end; anda substantially rigid internal member extending into the passageway of the male luer tip toward the first open end of the male luer tip;wherein: at least one of the male luer tip and the internal member is axially moveable between a first position and a second position relative to the other of the male luer tip and the internal member;the male luer tip and the internal member cooperate such that rotation of the male luer tip in a first direction relative to the housing increases an axial displacement between the first open end of the male luer tip and an end portion of the internal member;in the first position, the end portion of the internal member provides a substantially fluid-tight seal with respect to the first open end of the male luer tip so as to substantially prevent a flow of fluid through the male luer tip; andin the second position, the end portion of the internal member is spaced apart from the first open end so that fluid is permitted to flow through the first open end of the male luer tip. 2. The luer connector of claim 1, wherein the male luer tip is configured to rotate in a first direction with respect to the housing as a female connector is threadedly connected to the luer connector. 3. The luer connector of claim 1, wherein the male luer tip and the internal member cooperate such that rotation of the male luer tip in a second direction relative to the housing decreases the axial displacement between the first open end of the male luer tip and the end portion of the internal member. 4. The luer connector of claim 1, wherein the internal member is axially moveable relative to the male luer tip. 5. The luer connector of claim 1, wherein the internal member comprises an axial opening through at least a portion of the internal member, the axial opening being in fluid communication with the hollow bore of the housing and being configured to permit fluid to flow through the internal member. 6. The luer connector of claim 1, wherein the internal member has a solid cross-section along at least a substantial portion of the length thereof such that at least a substantial amount of fluid flowing through the luer connector is required to flow around an outside surface of the internal member. 7. The luer connector of claim 1, further comprising a chamber within the housing, the chamber being configured produce a change in volume as at least one of the male luer tip and the internal member axially moves between the first position and the second position relative to the other of the male luer tip and the internal member, and wherein the volume of the chamber is larger when the male luer tip and the internal member are in the first position. 8. The luer connector of claim 1, wherein the internal member comprises a helical or angled surface, the helical or angled surface configured to cooperate with the male luer tip and to cause the change in axial displacement between the male luer tip and the internal member as the male luer tip is rotated. 9. The luer connector of claim 1, further comprising a resilient member configured to bias the male luer tip and the internal member toward the first position. 10. The luer connector of claim 1, wherein the male luer tip has a conically shaped outside surface. 11. The luer connector of claim 1, wherein an opening in the first open end of the male luer tip and the end portion of the internal member have an ovular or other non-circular cross-sectional shape. 12. The luer connector of claim 11, wherein the opening in the first open end of the male luer tip has a tapered internal wall portion, the end portion of the internal member has a tapered external wall portion that cooperates with the internal wall portion of the male luer tip, the male luer tip and the internal member being configured such that relative rotation between the male luer tip and the internal member causes axial displacement between the male luer tip and the internal member. 13. A closed male luer connector comprising: a housing having a hollow bore, a first end, and a second end;a male luer tip of the closed male luer connector supported by the housing and configured to axially move with respect to the housing, the male luer tip having a first open end and a passageway through the male luer tip in fluid communication with the first open end; anda substantially rigid internal member extending into the passageway of the male luer tip toward the first open end of the male luer tip;wherein: the male luer tip is axially moveable between a first position and a second position relative to the internal member;in the first position, an end portion of the internal member provides a substantially fluid-tight seal with respect to the first open end of the male luer tip so as to substantially prevent a flow of fluid through the male luer tip; andin the second position, the end portion of the internal member is spaced apart from the first open end so that fluid is permitted to flow through the first open end of the male luer tip. 14. The luer connector of claim 13, wherein the male luer tip is configured to axially move from the first position to the second position as a female connector is threadedly connected to the luer connector. 15. The luer connector of claim 13, wherein the internal member has a solid cross-section along at least a substantial portion of the length thereof such that at least a substantial amount of fluid flowing through the luer connector is required to flow around an outside surface of the internal member. 16. The luer connector of claim 13, wherein the internal member comprises an axial opening through at least a portion of the internal member, the axial opening being in fluid communication with the hollow bore of the housing and being configured to permit fluid to flow through the internal member. 17. The luer connector of claim 13, further comprising a resilient member configured to bias the male luer tip toward the first position. 18. The luer connector of claim 13, wherein the male luer tip has a conically shaped outside surface.
