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. 本文公开了用于在由出血的组织空间的内表面限定的空腔内提供止血的改进的方法和设备。包括近端和远端的导管可以通过空腔中的组织空间的近侧开口被推进到空腔中。耦接至导管的远侧球囊可以邻近组织空间的远侧开口定位，并且被扩张以密封远侧开口。止血剂可以从导管施加到组织空间的内表面以抑制组织空间的出血。可以施加止血剂而不阻塞近侧开口、远侧开口和在二者之间延伸的具有止血剂的路径。
