Abstract
Disclosed herein are improved methods and apparatuses for providing hemostasis within a cavity defined by an internal surface of a bleeding tissue space. A catheter comprising a proximal end and a distal end may be advanced into the cavity through a proximal opening of the tissue space into the cavity. A distal balloon coupled to the catheter may be positioned adjacent a distal opening of the tissue space, and expanded to seal the distal opening. A hemostatic agent may be applied from the catheter to the internal surface of the tissue space to inhibit bleeding of the tissue space. The hemostatic agent may be applied without occluding the proximal opening, the distal opening, and a path extending therebetween with the hemostatic agent.
