A device for introducing a catheter into a vessel through a puncture in a vessel and for sealing the puncture. The device includes an elongated body having a proximal end and a distal end sized to be positioned within a tissue site which includes the puncture. The elongated body includes a utility lumen sized to allow a catheter to be delivered through the utility lumen. The utility lumen is positioned within the elongated body so positioning the elongated body within the tissue site allows a catheter delivered through the utility lumen to enter the vessel. The elongated body also includes a closure lumen having an entrance port. A closure composition can be delivered through the entrance port into the closure lumen. The closure lumen also includes an exit port adjacent the distal end of the elongated body. The closure composition delivered into the closure lumen can be delivered through the exit port to the tissue site adjacent the puncture.

What is claimed is: 1. A method for introducing a catheter through a puncture within a vessel and sealing the puncture, comprising: providing an apparatus comprising an elongated body having a distal end, the body including a circumferential wall having an inner surface and an outer surface, the body further including a utility lumen defined by the inner surface of the circumferential wall and a closure lumen separate from the utility lumen and being defined by a bore within the circumferential wall between the inner and outer surfaces, the closure lumen having a fluid delivery port located at a fixed distance from the distal end of the apparatus, positioning the elongated body within the tissue site, delivering a catheter through the utility lumen into the vessel, performing a treatment with the catheter, withdrawing the catheter through the utility lumen, and delivering a closure composition through the closure lumen to the puncture. 2. The method of claim 1, further comprising: delivering energy from at least one electrode on the elongated body to the closure composition delivered to the puncture. 3. The method of claim 1 wherein the elongated body includes a membrane positioned on the elongated body to be adjacent to a portion of tissue adjacent the puncture when the elongated body is positioned within the tissue site, and a second closure lumen through which a second closure composition can be delivered to the membrane. 4. The method of claim 3, further comprising: delivering the second closure composition through the second closure lumen to the membrane such that the second closure composition is delivered through the membrane to contact a portion of the tissue site adjacent the puncture. 5. The method of claim 4, further comprising: delivering energy from at least one electrode on the elongated body to the second closure composition which has been delivered to the tissue site.
