Abstract

A method and system for controlling inflammatory response at an internal tissue site of a patient utilizes a reduced-pressure treatment device. Controlling the inflammatory response may be accomplished in a number of ways that involve treating the inflammatory milieu. Treating the inflammatory milieu may include removing or moderating pro-inflammatory stimuli, e.g., fluids, enhancing perfusion of the tissue at or near the internal tissue site, or providing reduced-pressure therapy. The reduced-pressure treatment device is placed at or near the internal tissue site and is fluidly coupled to an external reduced-pressure source. The reduced-pressure treatment device provides reduced pressure proximate the tissue site and treats the inflammatory milieu. The reduced-pressure treatment device for controlling inflammatory response may be a minimally-invasive treatment device.

First claim

We claim:

1. A treatment device, comprising:
a first leg manifold member;
a second leg manifold member intersecting the first leg manifold member to form a central connection site;
an encapsulating envelope encapsulating the first leg manifold member and the second leg manifold member;
a plurality of fenestrations formed on the encapsulating envelope; and
a connecting interface coupled to the central connection site and fluidly coupled to the first leg manifold member and the second leg manifold member;
wherein the first leg manifold member and the second leg manifold member form two obtuse angles and two acute angles.

2. The treatment device of claim 1 , further comprising a sealing member operable to form a pneumatic seal over an internal tissue site.

3. The treatment device of claim 1 , wherein the first leg manifold member and the second leg manifold member each comprises a tapered end adapted for insertion through a trocar.

4. A system, comprising:
a treatment device configured to be disposed at an internal tissue site, comprising:
a leg manifold member comprising a foam;
an encapsulating envelope encapsulating the leg manifold member; and
a plurality of fenestrations formed on the encapsulating envelope;

a sealing member adapted to be disposed over the treatment device; and
a reduced-pressure interface adapted to be coupled to the encapsulating envelope in fluid communication with the leg manifold member.

5. The system of claim 4 , wherein the leg manifold member has an aspect ratio of at least 1.5 and not greater than 6.0.

6. The system of claim 4 , further comprising a reduced-pressure delivery conduit having a first end coupled to the reduced-pressure interface and a second end coupled to a quick connection fitting.

7. The system of claim 4 , wherein the leg manifold member is symmetrical about a major axis of the leg manifold member.

8. The system of claim 4 , wherein the leg manifold member comprises a tapered end adapted for insertion through a trocar.

9. The system of claim 4 , further comprising a pressure transducer within the leg manifold member.

10. The system of claim 4 , wherein:
the leg manifold member has an aspect ratio that is not greater than 6.0;
the leg manifold member is symmetrical about a major axis of the leg manifold member; and
the leg manifold member comprises a tapered end adapted for insertion through a trocar.

11. The system of claim 4 , further comprising a second leg manifold member intersecting the leg manifold member to form a central connection site.

12. The system of claim 4 , further comprising a second leg manifold member intersecting the leg manifold member to form two obtuse angles and two acute angles.
