Abstract
The illustrative embodiments described herein are directed to apparatuses, systems, and methods for applying reduced pressure to subcutaneous tissue site. In one illustrative embodiment, the apparatus includes a sleeve adapted for placement at a subcutaneous tissue site. The sleeve is further adapted to receive a manifold. The sleeve may also have an opening operable to transfer reduced pressure from the manifold to the subcutaneous tissue site. In one embodiment, the apparatus may also include a manifold that is insertable into the sleeve. The manifold may include at least one aperture, and may be operable to deliver reduced pressure to the subcutaneous tissue site via at least one aperture.

A method for applying reduced pressure treatment to a subcutaneous tissue site, the method comprising:
- inserting a sleeve having a distal end and a proximal end at the subcutaneous tissue site such that an opening on the distal end of the sleeve is adjacent the subcutaneous tissue site;
- inserting a manifold having a distal end and a proximal end into the sleeve, wherein the manifold includes:
- a fluid passageway for delivering reduced pressure between the distal end and the proximal end, and
- a sidewall having at least one aperture and a flange substantially surrounding the sidewall of the manifold, wherein the flange forms a chamber between the at least one aperture and the opening, the flange having at least one hole allowing fluid communication between a distal side of the flange and a proximal side of the flange, when the distal end of the manifold is inserted into the sleeve and the at least one aperture is aligned with the opening, and wherein the flange is capable of extracting a substance from the proximal end of the sleeve when the distal end of the manifold is completely removed from the proximal end of the sleeve;
- and
- supplying reduced pressure to the subcutaneous tissue site via the at least one aperture, the chamber, and the opening.
A method for providing reduced pressure treatment to a tissue site, comprising:
- inserting a distal end of a sleeve subcutaneously through an opening in skin adjacent to the tissue site;
- positioning an opening in a sidewall of the sleeve adjacent to the tissue site;
- inserting a distal end of a manifold into a proximal end of the sleeve, wherein the manifold comprises:
- a fluid passageway for delivering reduced pressure between the distal end and a proximal end, and
- a flange substantially surrounding the sidewall of the manifold, the flange having at least one hole allowing fluid communication between a distal side of the flange and a proximal side of the flange, when the distal end of the manifold is inserted into the sleeve;
- aligning an aperture in a sidewall of the manifold with the opening in the sleeve adjacent to the tissue site, wherein the aperture and the opening are radially displaced by a chamber;
- sealing the manifold and the sleeve about the skin;
- providing reduced pressure treatment to the tissue site through the aperture in the manifold, the chamber, and the opening in the sleeve;
- removing the distal end of the manifold from the proximal end of the sleeve such that the manifold is completely removed from the sleeve;
- and
- reinserting the distal end of the manifold into the proximal end of the sleeve.
A method for providing reduced pressure treatment to a tissue site, the method comprising:
- inserting a distal end of a sleeve subcutaneously to the tissue site;
- positioning an opening in the distal end of the sleeve sidewall adjacent to the tissue site;
- inserting a distal end of a manifold into a proximal end of the sleeve, wherein the manifold comprises:
- a fluid passageway for delivering reduced pressure between the distal end and the proximal end,
- a sidewall having at least one aperture and a flange disposed between the aperture and the distal end of the manifold, the flange having at least one hole allowing fluid communication between a distal side of the flange and a proximal side of the flange, when the distal end of the manifold is inserted into the sleeve;
- aligning the aperture in the manifold with the opening in the sleeve adjacent to the tissue site, wherein the aperture and the opening are radially displaced by a chamber;
- providing reduced pressure treatment to the tissue site through the aperture in the manifold, the chamber, and the opening in the sleeve;
- and
- removing the distal end of the manifold from the proximal end of the sleeve such that the flange is capable of extracting a substance from the proximal end of the sleeve when the manifold is completely removed from the sleeve.
