The inflation tube defines an inflation lumen. The flashback tube defines a flashback lumen. The dual lumen tube has first and second lumens and is positioned distal of the inflation tube and flashback tube. The inflation tube and flashback tube are integrally connected to the dual lumen tube at the bond portion with the inflation lumen in fluid communication with the first lumen and the flashback lumen in fluid communication with the second lumen. The inflatable balloon is mounted at a distal end of the dual lumen tube and is in fluid communication with the inflation lumen. ## Claims ### Claim 1 A vascular closure device, comprising: an inflation tube defining an inflation lumen; a flashback tube defining a flashback lumen; a dual lumen tube having first and second lumens that are fixed relative to each other, the dual lumen tube being positioned distal of the inflation tube and flashback tube; a bond portion wherein the inflation tube and flashback tube are integrally connected to the dual lumen tube with the inflation lumen in fluid communication with the first lumen, and the flashback lumen in fluid communication with the second lumen, the bond portion and dual lumen tube having an integral, single-piece construction; an inflatable balloon mounted at a distal end of the dual lumen tube and being in fluid communication with the inflation lumen. ### Claim 2 (depends on 1) A vascular closure device according to claim 1 wherein the second lumen terminates proximal of the inflatable balloon. ### Claim 3 (depends on 1) A vascular closure device according to claim 1 wherein the second lumen is configured as a bioadhesive ejection lumen, wherein a bioadhesive is ejected through the second lumen. ### Claim 4 (depends on 1) A vascular closure device according to claim 1 further comprising a pull wire tube that defines a pull wire lumen, the pull wire tube extending through the first lumen and being connected to the dual lumen tube, the inflation tube and the flashback tube at the bond portion. ### Claim 5 (depends on 4) A vascular closure device according to claim 4 wherein the pull wire tube includes a metal tube having a PTFE jacket. ### Claim 6 (depends on 4) A vascular closure device according to claim 4 further comprising a sealing member positioned distal of the inflatable balloon, and a pull wire extending through the pull wire lumen, the sealing member being detachably mounted to a distal end of the pull wire, the pull wire being operable to release the sealing member. ### Claim 7 (depends on 6) A vascular closure device according to claim 6 wherein the distal sealing member includes a bioresorbable material. ### Claim 8 A vascular closure device, comprising: an inflation tube having an inflation lumen; a flashback tube having a blood flashback lumen; a dual lumen tube having first and second lumens that are fixed relative to each other, the dual lumen tube extending distally from the inflation tube and flashback tube; a pull wire tube extending through one of the first and second lumens; wherein the inflation tube, flashback tube, dual lumen tube, and pull wire tube are permanently connected together at a bond portion, the bond portion and dual lumen tube having an integral, single-piece construction. ### Claim 9 (depends on 8) The vascular closure device of claim 8, wherein the first lumen is in flow communication with one of the inflation lumen and the flash back lumen. ### Claim 10 (depends on 8) The vascular closure device of claim 8, wherein the pull wire tube extends side-by-side with the inflation tube and the flash back tube at a location proximal of the bond portion. ### Claim 11 (depends on 8) The vascular closure device of claim 8, wherein the bond portion has a continuous, integral construction comprising portions of the inflation tube, flashback tube, dual lumen tube, and pull wire tube. ### Claim 12 (depends on 8) The vascular closure device of claim 8, wherein the inflation tube, flashback tube, dual lumen tube and pull wire tube are heat bonded together at the bond portion. ### Claim 13 (depends on 8) The vascular closure device of claim 8, wherein the pull wire tube comprises a metal tube having a polymer jacket. ### Claim 14 (depends on 8) The vascular closure device of claim 8, further comprising an inflation balloon positioned at a distal end portion of the dual lumen tube and in flow communication with the inflation lumen. ### Claim 15 A vascular closure device, comprising: a bond portion; an inflation tube extending proximally from the bond portion and having an inflation lumen; a flashback tube extending proximally from the bond portion and having a flashback lumen; a dual lumen tube extending distally from the bond portion and having first and second lumens in flow communication with the inflation lumen and the flashback lumen, respectively, the first and second lumens being fixed relative to each other; wherein the bond portion and dual lumen tube have an integral, single-piece construction. ### Claim 16 (depends on 15) The vascular closure device of claim 15, wherein the bond portion includes a connection between the inflation tube, flashback tube and dual lumen tube in an integral, single piece construction. ### Claim 17 (depends on 15) The vascular closure device of claim 15, wherein the second lumen terminates with a distal portion positioned proximal of the inflation balloon. ### Claim 18 (depends on 15) The vascular closure device of claim 15, further comprising a pull wire extending through the first lumen and the inflation lumen. ### Claim 19 (depends on 15) The vascular closure device of claim 15, further comprising a wire tube extending through one of the first and second lumens at a location distal of the bond portion. ### Claim 20 (depends on 19) The vascular closure device of claim 19, wherein the wire tube extends adjacent to the inflation tube and the flashback tube at a location proximal of the bond portion in a side-by-side arrangement. ### Claim 21 (depends on 19) The vascular closure device of claim 19, wherein the wire tube extends distally beyond the inflation balloon.
