Abstract
A reduced pressure delivery system for applying reduced pressure tissue treatment to a tissue site is provided. The system includes a manifold delivery tube and a balloon having an inner space. The balloon is capable of assuming collapsed and expanded positions. The system further includes a manifold having a plurality of flow channels. The manifold is disposed within the inner space of the balloon. A sharp tip is configured to be delivered within the manifold delivery tube to puncture the balloon.
Claims34
A method for applying reduced pressure to a tissue site with a reduced pressure delivery system, the method comprising:
- percutaneously inserting a tube having a passageway through tissue to place a distal end of the tube adjacent a tissue site;
- inflating a balloon to dissect tissue adjacent the tissue site, thereby creating a void;
- delivering a manifold having a plurality of flow channels through the passageway;
- positioning the manifold in the void such that at least a portion of the flow channels are in fluid communication with the tissue site;
- and
- applying a reduced pressure to the tissue site through the manifold.
A method of administering a reduced pressure tissue treatment to a tissue site comprising:
- percutaneously inserting a tube through a skin tissue of a patient to place a distal end of the tube adjacent the tissue site, the tube having at least one passageway;
- applying a first reduced pressure to an inner space of an impermeable membrane, the inner space containing a manifold having a plurality of flow channels;
- delivering the impermeable membrane and the manifold through the passageway to the tissue site;
- rupturing the impermeable membrane to place the manifold in contact with the tissue site;
- and
- applying a second reduced pressure to the tissue site through the flow channels of the manifold.
