Abstract: An apparatus for inhibiting blood loss from a puncture site. The apparatus may include means for locating a puncture site in a blood vessel wall. This apparatus is comprised of a tube and an elongated member that is positioned around the tube. The elongated member includes a proximal end and a distal end. Around the tube is also a dissolvable distal capsule, the distal capsule including a proximal end and a distal end, wherein the proximal end of the distal capsule attaches to the distal end of the elongated member. Inside the distal capsule is hemostatic material such as a sponge.

Abstract: An apparatus to intervascularly promote hemostasis at a blood vessel puncture site with an inner lumen pressure and an outer lumen pressure has a flexible plug having a center, a top surface, and a bottom surface, and a release mechanism coupled to the center to position and release the flexible plug intervascularly at the blood vessel puncture site. The inner lumen pressure is greater than the outer lumen pressure to forceably secure the flexible plug around the blood vessel puncture site.
