The catheter shaft may engage one or more push connectors captured within a passage in the hub. Related are methods of manufacturing a catheter hub, including connecting first and second generally symmetrical halves of a hub over a connector, and then inserting a catheter shaft into the connector, such as by pushing it through a ring with inwardly directed fingers to form a secure locking engagement. ## Claims ### Claim 1 An apparatus for forming a catheter assembly, comprising: a catheter shaft; and a hub including at least one connector for irremovably connecting the catheter shaft to the hub. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the at least one connector comprises a push connector captured within a passage of the hub. ### Claim 3 (depends on 2) The apparatus according to claim 2, wherein the push connector comprises a ring including a plurality of inwardly directed fingers for engaging the shaft. ### Claim 4 (depends on 3) The apparatus according to claim 3, the hub further including a retainer for engaging the ring to prevent movement relative to the hub. ### Claim 5 (depends on 1) The apparatus according to claim 1, wherein the at least one connector comprises a first connector for connecting to a first proximal portion of the catheter shaft within the hub and further including a second connector for connecting to a second portion disposed distally of the first proximal portion of the catheter shaft within the hub. ### Claim 6 (depends on 5) The apparatus according to claim 5, wherein the proximal portion of the catheter shaft includes a single lumen and the second portion of the shaft includes a dual lumen. ### Claim 7 (depends on 5) The apparatus according to claim 5, wherein the hub comprises a first port in communication with a first lumen of the proximal portion of the catheter shaft and a second port in communication with a second lumen of the second portion. ### Claim 8 (depends on 5) The apparatus according to claim 5, where the first connector has a larger diameter than the second connector. ### Claim 9 (depends on 1) The apparatus according to claim 1, wherein the hub comprises two generally symmetrical halves. ### Claim 10 An apparatus for connecting to a catheter shaft for forming a catheter, comprising: a hub including an internal passage including at least one push connector for connecting the shaft to the hub. ### Claim 11 (depends on 10) The apparatus according to claim 10, wherein the at least one connector comprises a push connector captured within a passage of the hub. ### Claim 12 (depends on 11) The apparatus according to claim 11, wherein the push connector comprises a ring including a plurality of inwardly directed fingers for engaging the shaft. ### Claim 13 (depends on 12) The apparatus according to claim 12, the hub further including a retainer for retaining the ring to prevent movement relative to the hub. ### Claim 14 (depends on 10) The apparatus according to claim 10, wherein the at least one connector comprises a first connector for connecting to a first proximal portion of the shaft within the hub and further including a second connector for connecting to a second portion of the shaft disposed distally of the first proximal portion of the shaft within the hub. ### Claim 15 (depends on 14) The apparatus according to claim 14, wherein the hub comprises a first port for communicating with a first lumen of the proximal portion of the shaft and a second port for communicating with a second lumen of the second portion of the shaft. ### Claim 16 (depends on 14) The apparatus according to claim 14, where the first connector has a larger diameter than the second connector. ### Claim 17 (depends on 14) The apparatus according to claim 14, wherein the hub comprises two generally symmetrical halves. ### Claim 18 An apparatus for forming a catheter, comprising: a catheter shaft; and a hub mechanically connected to the catheter shaft without using an adhesive. ### Claim 19 (depends on 18) The apparatus of claim 18, wherein the hub comprises a push connector for connecting to the shaft. ### Claim 20 (depends on 18) The apparatus of claim 18, further including one or more annular seals for sealing the catheter shaft within the hub. ### Claim at position 21 21-25.
