A valve for selectively permitting a fluid flow between first and second medical implements is disclosed. The valve has a housing with an interface suitable for receiving a connector portion of a first medical device such as a catheter, and a seal made of a flexible material. The seal has a first end in fluid communication with the interface, a second end suitable for receiving the second medical device, and at least one slit in fluid communication with the first end and the second end. The slit defines a restricted fluid flow path and a relatively small interior volume when in an undisturbed state, defines an expanded fluid flow path and a larger interior volume upon the introduction of the second medical instrument into the slit, and retracts to define a restricted flow path and a small interior volume upon the withdrawal of the second medical device from the seal.
1. A medical connector for permitting fluid flow between a first medical device and a second medical device, the medical connector comprising: a housing comprising a downstream end configured to receive a first medical device and an upstream end configured to receive a second medical device, wherein
1. A medical connector for permitting fluid flow between a first medical device and a second medical device, the medical connector comprising: a housing comprising a downstream end configured to receive a first medical device and an upstream end configured to receive a second medical device, wherein at least a portion of the housing defines a first side opening and a second side opening such that the first side opening and the second side opening each define a recess with respect to an inner surface of the housing;a seal comprising a downstream end, an upstream end configured to receive the second medical device, and a normally substantially closed passage, the seal further comprising a seal body and a transverse flange, wherein the body is made of flexible material and has first and second lateral portions each having an upper surface, and wherein the transverse flange is disposed proximal to the upstream end of the seal and has a lower surface;wherein the seal is disposed within the housing such that the transverse flange extends at least partially across the axial opening, and the first lateral portion of the seal body extends at least partially into the first side opening and the second lateral portion of the seal body extends at least partially into the second side opening;wherein the first and second side openings have top edges that define the portions of the side openings nearest the axial opening, and the first and second lateral portions of the seal body have shoulders configured to engage the top edges of the first and second side openings, and the top edges of the side openings are remote from the axial opening to impart a tensile force to the seal between the transverse flange and the shoulders. 2. The medical connector of claim 1, wherein the seal body comprises a generally flat slab. 3. The medical connector of claim 1, wherein the first lateral portion of the seal body generally opposes the second lateral portion of the seal body. 4. The medical connector of claim 1, wherein the side openings are located in regions on opposing sides of the housing. 5. The medical connector of claim 1, wherein the first lateral portion of the seal body extends through the first side opening and the second lateral portion of the seal body extends through the second side opening. 6. The medical connector of claim 1, wherein the first lateral portion and the second lateral portion of the seal body are exposed with respect to an exterior of the medical connector. 7. The medical connector of claim 1, wherein the transverse flange takes on a concave configuration. 8. The medical connector of claim 1, wherein the medical connector is configured to selectively permit an unobstructed flow of fluid therethrough. 9. The medical connector of claim 1, wherein upon removal of the second medical device from the seal, fluid in the seal is urged towards the downstream end of the seal. 10. The medical connector of claim 1, wherein the upstream end of the housing is configured to interface with a Luer. 11. The medical connector of claim 1, wherein the upstream end of the seal is configured to receive a Luer. 12. The medical connector of claim 1, wherein the seal further comprises a neck formed proximal to an upstream end of the seal body. 13. The medical connector of claim 12, wherein the seal body, neck, and transverse flange form an integral unit. 14. The medical connector of claim 1, wherein the housing further comprises a lead cannula extending from a lower inner surface of the housing toward the upstream end of the housing. 15. The medical connector of claim 14, wherein at least a portion of the lead cannula has a cylindrical outer surface. 16. The medical connector of claim 14, wherein the seal further comprises a lead lumen formed in a downstream end of the seal body and in fluid communication with the passage. 17. The medical connector of claim 16, wherein the lead lumen is permitted to slide along an outer surface of the lead cannula and to move toward the lower inner surface of the housing when the second medical device is inserted into the medical connector. 18. The medical connector of claim 17, wherein the lead cannula is centered on an axis parallel to or collinear with a longitudinal axis of the housing.
