A medical access device provides needleless access to patient fluid lines such as intravascular catheters. A preformed crimp ring is attached around a septum and the top end of the housing of the medical access device. The crimp ring is configured to hold the septum in place. The septum provides access for a tubular portion of a medical device such as a male luer taper of a syringe. The crimp ring is then attached by mechanical attachment and/or chemical adhesion to the housing to minimize axial and rotational movement between the septum and the housing.

The invention claimed is: 1. An access connector comprising: a housing having a body and a base, the base including an annular channel for receiving a bottom edge of the body and a rim extending upwardly from the annular channel into the body; a septum having a top disk, a bottom disk with an annular groove in a bottom surface, a column extending between the top disk and the bottom disk, and a resealable slit extending through the top disk, column, and bottom disk to allow for insertion of a tubular portion of a medical device; and a crimp ring mechanically attached to the top disk of the septum and attached to a top end of the body of the housing by chemical bonding, mechanical attachment, or a combination thereof, such that the crimp ring minimizes axial and rotational movement between the septum and the housing, wherein the septum is positioned within the housing such that the annular groove in the bottom surface of the bottom disk is engaged by the rim of the base, an outer portion of the bottom disk is held between the body and the rim, and an outer portion of the top disk is held between the crimp ring and the top end of the body, wherein the slit extending through the top disk is biased closed by the crimp ring and the slit extending through the bottom disk is biased closed by the rim, the slit being opened by insertion of a tubular medical device therethrough to allow fluid flow through the septum. 2. The access connector of claim 1 wherein the crimp ring is fabricated from one of thermoplastic and metal. 3. The access connector of claim 1 and further comprising: a lip on the crimp ring; and a ridge on the top disk of the septum engaged with the lip. 4. The access of connector of claim 1 and further comprising: a barb on the crimp ring; and a recess on the body for engaging the barb. 5. The access connector of claim 1 and further comprising: a barb on the crimp ring, the barb penetrating the surface of the body. 6. The access connector of claim 1 wherein the crimp ring is bonded to the body by one of ultrasonic welding, solvent bonding and adhesive bonding. 7. An access connector comprising: a septum having a top disk, a bottom disk with an annular groove in a bottom surface, a column extending between the top disk and the bottom disk, and a resealable slit extending through the top disk, column, and bottom disk; a crimp ring mechanically attached to the top disk of the septum, the crimp ring being formed prior to attachment to the top disk; and a housing attached to the crimp ring by chemical bonding, mechanical attachment, or a combination thereof, such that the crimp ring minimizes axial and rotational movement between the septum and the housing and forms a resealable channel with the septum for accessing a patient fluid line with a tubular portion of a medical device, the housing including a body and a base, the base having an annular channel for receiving a bottom edge of the body and a rim extending upwardly from the annular channel into the body; wherein the septum is positioned within the housing such that the annular groove in the bottom surface of the bottom disk is engaged by the rim of the base, an outer portion of the bottom disk is held between the body and the rim, and an outer portion of the top disk is held between the crimp ring and a top end of the body, wherein the slit extending through the top disk is biased closed by the crimp ring and the slit extending through the bottom disk is biased closed by the rim, the slit being opened by insertion of a tubular medical device therethrough to allow fluid flow through the septum. 8. The access connector of claim 7 wherein the chemical bonding is one of ultrasonic welding, solvent bonding and adhesive bonding. 9. The access connector of claim 7 wherein the crimp ring and body are snapped together. 10. The luer access connector of claim 7 and further comprising: at least one cut-out in the crimp ring; and at least one lug on the housing positioned within the cut-out. 11. The access connector of claim 7, further comprising: a lip extending around the crimp ring; and a ridge extending around the top disk of the septum, the ridge engaged with the lip. 12. A method of making an access connector, the method comprising; positioning a crimp ring over a top disk of a septum having a slit extending from the top disk to a bottom disk; inserting the septum within a housing having a body to form a resealable channel including the slit within the housing; attaching the crimp ring to a top end of the housing, such that an outer portion of the top disk of the septum is held between the crimp ring and the top end of the housing thereby biasing the slit at the top disk of the septum closed; and attaching a base to a bottom of the housing, the base having an annular channel for receiving a bottom edge of the body and a rim extending upwardly from the annular channel into the body; wherein an annular groove in a bottom surface of the bottom disk is engaged by the rim, and an outer portion of the bottom disk of the septum is held between the body and the rim, thereby biasing the slit at the bottom disk closed. 13. The method of claim 12 wherein the crimp ring is formed of thermoplastic or metal. 14. The method of claim 12 wherein the crimp ring and housing are attached by chemical bonding, mechanical attachment or a combination thereof. 15. The method of claim 12 wherein attaching the crimp ring to the housing further comprises: pressing at least one barb into the housing. 16. The method of claim 12 wherein positioning the crimp ring further comprises: engaging a lip of the crimp ring with a ridge of the septum. 17. The method of claim 12 and further comprising: contacting the crimp ring with a mandrel and forming base to deform the crimp ring.
