Abstract
A posterior nasal pack has a pair of adjoining inflatable bags sharing a common wall. A U-shaped channel adapted partially to surround the posterior edge of the septum is formed by the anterior walls of the bags which walls join in a common wall at the base of the channel. The bag exterior surfaces are covered with a foamed elastomer molded to conform generally to the bony protuberances and recesses located in the posterior portion of the nasal cavity. Two flexible tubes, each attached in fluid connection with a respective bag and extending forwardly therefrom for applying a source of fluid pressure to the bags. A string attached to the posterior end of the pack aids in its removal after bleeding has been stopped. The pack is positioned in the nasal cavity by attaching it to a pair of catheters which have been inserted into a patient's nostrils, passed through the nasopharynx, and out through the patient's mouth. As the catheters are withdrawn from the nostrils, the pack is directed into position in the nasopharynx partially surrounding the posterior edge of the septum. The attached tubes are connected to a source of fluid pressure, and the bags are inflated to expand the pack and apply hemostatic pressure to substantially all surfaces in the posterior portion of the nasal cavity.
