A vascular closure device includes a vessel locating device, a sealant delivery device, a detachable sealing tip, and a suture. The vessel locating device includes an expandable portion configured to extend through and temporarily seal a vessel puncture from within a vessel. The sealant delivery device is configured to deliver a first volume of flowable sealant to the vessel puncture along an exterior of the vessel. The detachable sealing tip is carried at a distal end of the vessel locating device. The suture is connected to and extends proximally from the detachable sealing tip. The detachable sealing tip is configured for release within the first volume of flowable sealant upon withdrawal of the vessel locating device through the first volume of flowable sealant. The suture is anchored at a location proximal of the detachable sealing tip.
