1. A medical device for applying pressure and absorbing liquid in a nasal cavity having walls, comprising;
- a packing member having a length that includes;
a posterior section having a width and a length;
a body section joined to said posterior section and having dimensions including a height, a width, and a length; and
an anterior section joined to said body section;
a wrap member having a length and being disposed about portions of said anterior section for preventing said anterior section portions from unwantedly adhering to nasal cavity walls, said wrap member length being substantially less than a combined length of said posterior section and body section lengths, and in which said posterior section and said body section remain exposed to the nasal cavity walls and free of contact from said wrap member along substantial portions of said combined length.

Abstract
A device for applying pressure using absorbed fluid is disclosed. The device has particular utility in body cavities, such as nasal or sinus passages. In one embodiment, the device includes an expandable packing member and a delivery/draining tube. The packing member is insertable into a body cavity or body wound and expands when the packing member absorbs one or more fluids. After reaching the desired expansion, the packing member contacts body walls and applies pressure thereto. The delivery/draining tube is able to deliver fluid for treatment purposes or for expanding the packing member to a desired size. The delivery/draining tube is also used in removing body or other fluids from the body cavity or wound that are absorbed by the packing member. Rehydrating fluid is also utilized in facilitating the removal of the packing member from the body cavity or wound. In another embodiment, the packing member is definable to include anterior, body and posterior sections. A wrap member is disposed about portions of the anterior section that inhibits expansion thereof by liquid, as well as preventing adhesion or unwanted engagement between said anterior section portions and parts of the body cavity in which the packing member is inserted.
