Abstract
Official abstract text for this publication.
Apparatus for sealing a puncture communicating with a blood vessel includes a porous carrier formed from lyophilized hydrogel or other material. The plug may include at least first and second hydrogel precursors and a pH adjusting agent carried by the porous carrier in an unreactive state prior to exposure to an aqueous physiological environment. Once exposed to bodily fluids, the carrier expands as the lyophilized material hydrates to enhance and facilitate rapid hemostasis of the puncture. When the plug is placed into the puncture, the natural wetting of the plug by bodily fluids (e.g., blood) causes the first and second precursors to react and cross-link into an adhesive or “sticky” hydrogel that aids in retaining the plug in place within the puncture.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for sealing a blood vessel wall penetration disposed at an end of a tissue tract, said apparatus comprising: a shaft having a proximal end and a distal end; an occlusion element near the distal end of the shaft, said occlusion element being transformable between a radially contracted configuration for passage through the tissue tract and a radially expanded configuration for deployment within the blood vessel to occlude the penetration; a he…
