Abstract:
1. A method for hemostasis of a puncture site in a wall of a blood vessel at an end of a tissue tract having a sheath therein, the method comprising: providing a locating member having a proximal end, a distal end, and an expansible member disposed on the distal end thereof, inserting the locating member through the sheath in the tissue tract so that the expansible member on the locating member enters a lumen of the blood vessel; expanding the expansible member on the inserted locating member and drawing the inserted locating member proximally so that the expanded expansible member covers the puncture site in the vessel wall; removing the sheath from the tissue tract while the inserted locating member remains in place; providing a tubular compression member having a proximal end, a distal end, a central passage between said proximal end and said distal end, and an expansible tissue compression element disposed over the distal portion thereof, and advancing the tubular compression member over the inserted locating member after the sheath has been removed from the tissue tract so that the locating member is received in the central passage of the tubular compression member and a distal end of the expansible tissue compression element is located within the tissue tract at a predetermined distance proximal from the wall of the blood vessel to define a tissue compression region; and expanding the expansible tissue compression element within the tissue tract above the blood vessel wall to apply pressure against subcutaneous tissue and to compress said tissue over the puncture site in the blood vessel wall to promote hemostasis, wherein the compression element is not in direct contact with the vessel wall, and wherein the expansible tissue compression element on the compression member is left in place until hemostasis has been achieved.
