A vascular access device may include a body, housing, neck, and a septum with a substantially non-gaseous cross section. A method of operating a septum of a vascular access device may include providing a vascular access device in an external environment and actuating the septum without transferring a substantial amount of gas from within the device to the external environment of the device.

1. A medical device, comprising: a vascular access device including a body having a neck portion and a lower portion that defines a cavity, the neck portion having a smaller cross-sectional area than the lower portion;a septum housed partially within the neck portion, a portion of the septum extending out of an upper opening in the neck portion and being fixed to an exterior surface of the body, wherein the septum includes two opposing slit surfaces;a rigid structure positioned within the neck portion and at least partially encompassing the septum, the rigid member being movable from within the neck portion and into the cavity portion when the vascular access device is accessed by a separate extravascular device. 2. The medical device of claim 1, further comprising a spring in contact with the rigid structure, wherein the force of the spring biases the rigid structure from the cavity towards the neck portion. 3. The medical device of claim 1, wherein the two opposing slit surfaces of the septum are in contact along a portion of the septum when the septum is in a closed position. 4. The medical device of claim 3, wherein the rigid structure at least partially encompasses the portion of the septum having the two opposing slit surfaces of the septum in contact when the septum is in a closed position. 5. The medical device of claim 1, wherein a bottom portion of the septum contacts an inner surface of the cavity. 6. The medical device of claim 1, wherein the neck portion has a length between a top and bottom of the neck, and the rigid structure has a length between the top and bottom of the rigid structure, the length of the neck portion being approximately equal to or greater the length of the rigid structure. 7. The medical device of claim 1, wherein the neck portion further includes a top surface, and the septum being secured to the top surface of the neck portion. 8. A medical device, comprising: a vascular access device including a body having a neck portion and a lower portion that defines a cavity, the neck portion having a smaller cross-sectional area than the lower portion;a septum housed at least partially within the neck portion, a portion of the septum extending out of an upper opening in the neck portion and being fixed to an exterior surface of a top portion of the body, the septum comprising two opposing slit surfaces housed partially within the neck portion;a rigid structure disposed intermediate between an inner surface of the neck portion and the septum and at least partially encompassing the septum;wherein the rigid structure is movable from between the inner surface of the neck portion and the two opposing surfaces of the septum into the cavity. 9. The medical device of claim 8 further comprising a spring in contact with the rigid structure, said spring biasing the rigid structure from the cavity toward the neck portion. 10. The medical device of claim 8 wherein when the vascular access device is accessed by a separate access device, the two opposing slit surfaces are forced in opposing lateral directions toward the body of the device. 11. The medical device of claim 10 wherein when the vascular access device is accessed by a separate access device the rigid structure is forced against the spring and into the cavity. 12. The medical device of claim 10 wherein when the vascular access device is accessed by a separate access device an open fluid path through the device is formed. 13. The medical device of claim 8, wherein the two opposing slit surfaces of the septum are in contact along a portion of the septum when the septum is in a closed position. 14. The medical device of claim 13, wherein the rigid structure at least partially encompasses the portion of the septum having two opposing slit surfaces of the septum in contact when the septum is in a closed position. 15. The medical device of claim 8, wherein the portion of the septum is fixed to an exterior surface of a top portion of the body. 16. A medical device, comprising: a vascular access device including a body having an inner surface, a cavity formed within the inner surface of the body, and a neck portion having an inner surface;a septum housed partially within neck portion, a portion of the septum extending out of the neck portion and being fixed to an exterior surface of the body, wherein the septum includes two opposing slit surfaces;a rigid structure housed between the inner surface of the neck and the septum and at least partially encompassing the septum;wherein the rigid structure is capable of moving from between the inner surface of the neck and the septum into the cavity of the body when the vascular access device is accessed by a separate extravascular device; anda spring in contact with the rigid structure and the inner surface of the cavity, the spring biasing the rigid structure from the cavity toward the neck. 17. The medical device of claim 16, wherein the neck, the rigid structure, and septum form a cross section in which the opposing slit surfaces are in contact.
