Hemostatic system for body cavities

Abstract

Bleeding is controlled on an inner surface of a body cavity by inserting into the cavity an expandable balloon which is covered by a hemostatic shroud, expanding the balloon, and compressing the shroud against the site of bleeding. The balloon may be disposed around a central tube to supply inflation medium. The tip of the device is soft to aid with insertion. The invention includes the corresponding devices and systems for such control of bleeding within a body cavity or passageway, as well as a method of making the devices.

Description

[0001] This application is a continuation-in-part of U.S. patent application Ser. No. 09 / 921,864 filed Aug. 10, 2001, which in turn is a continuation-in-part of U.S. patent application Ser. No. 09 / 406,166 filed Sep. 27, 1999, which in turn is a continuation-in-part of U.S. patent application Ser. No. 09 / 057,414, filed on Apr. 8, 1998.TECHNICAL FIELD [0002] This invention relates generally to medical devices and methods of use, and more specifically, to materials, apparatus, and methods for facilitating hemostasis within a body cavity or passageway. BACKGROUND OF THE INVENTION [0003] Nasal passageways, for example, are often susceptible to uncontrolled bleeding caused by various forms of trauma, disease or cellular dysfunction. Methods and devices for controlling, limiting or stopping such bleeding would be useful in a variety of situations, ranging from emergency room care to long term care.

AI Technical Summary

Benefits of technology

The solution effectively controls bleeding by enhancing blood clot formation and allows for easy removal of the hemostatic agent without re-bleeding, even in small and sensitive areas like the nasal passageway.

Problems solved by technology

Nasal passageways, for example, are often susceptible to uncontrolled bleeding caused by various forms of trauma, disease or cellular dysfunction.

Bleeding is typical after nasal related surgeries or procedures, and epistaxis related to a patient's nasal passageway can be difficult to control.

Insertion, application, and subsequent removal of these materials, however, can be difficult in small body passageways, such as nasal cavities.
