Abstract:
1. A device for promoting hemostasis in a blood vessel puncture by compressing a layer of subcutaneous tissue adjacent the puncture, wherein the puncture is accessed subcutaneously through a sheath having a proximal portion, a distal end initially positionable within the puncture, and an axial channel, the device comprising: a catheter dimensioned to be received within the axial channel and having an axial lumen communicating with an open distal end, the sheath being axially movable relative to the catheter between a distal position and a proximal position; an elongate, flexible locater member extending through the catheter lumen and the distal end of the catheter and having a distal portion extensible into the interior of the blood vessel through the puncture; an expansible compression element coupled to the distal end of the catheter; and a puncture locating means spaced from the distal end of the compression element by a predetermined axial distance in the distal direction, the predetermined axial distance being sufficient to position the compression element distal end outside of the blood vessel and spaced proximally from the puncture when the puncture locating means is disposed within the puncture, thereby to position the layer of subeuteanous tissue between the puncture and the compression element distal end; wherein a force applied to the compression element compresses the layer of subcutaneous tissue.
