Abstract
A porous conduit may be suitable for use in treating a tissue site, and may include a central lumen and a porous wall positioned substantially concentric about the central lumen. The porous wall may have an open porous structure that may define a plurality of interconnected pores in fluid communication with one another. As part of a system, the porous conduit may be used with a manifold adapted to be positioned at a tissue site, a sealing drape adapted to cover the manifold to provide a sealed space relative to the tissue site, and a therapy device including a reduced-pressure source. The porous conduit may be disposed in the sealed space and in fluid communication between the sealed space and the reduced-pressure source.
Claims31
A system for treating a tissue site, comprising:
- a manifold adapted to be positioned proximate the tissue site;
- a sealing drape adapted to cover the manifold and the tissue site to provide a sealed space between the sealing drape and the tissue site;
- a porous conduit adapted to be in fluid communication with the manifold and the sealed space, comprising:
- a central lumen,
- a first porous wall substantially concentric about the central lumen, wherein the first porous wall has an open porous structure defining a plurality of interconnected pores in fluid communication with one another,
- a barrier layer substantially concentric about the first porous wall, wherein the barrier layer is comprised of a non-porous material, and
- a second porous wall substantially concentric about the barrier layer, wherein the second porous wall has an open porous structure defining a plurality of interconnected pores in fluid communication with one another, and wherein the barrier layer substantially precludes fluid communication laterally between the first porous wall and the second porous wall;
- and
- a therapy device adapted to be in fluid communication with the porous conduit.
A system for treating a tissue site, comprising:
- a manifold adapted to be positioned proximate the tissue site;
- a sealing drape adapted to cover the manifold and the tissue site to provide a sealed space between the sealing drape and the tissue site;
- a porous conduit adapted to be disposed in the sealed space in fluid communication with the manifold and the sealed space, comprising:
- a central lumen, and
- a porous wall positioned substantially concentric about the central lumen, wherein the porous wall has an open porous structure defining a plurality of interconnected pores in fluid communication with one another;
- and

A system for treating a tissue site, comprising:
- a manifold adapted to be positioned proximate the tissue site and to distribute reduced pressure to the tissue site;
- a sealing drape adapted to cover the manifold and the tissue site to provide a sealed space between the sealing drape and the tissue site;
- a porous conduit adapted to be disposed in the sealed space in fluid communication with the manifold and the sealed space, comprising:
- a central lumen,
- a first porous wall substantially concentric about the central lumen, wherein the first porous wall has an open porous structure defining a plurality of interconnected pores in fluid communication with one another, wherein the first porous wall is comprised of bonded particles defining the interconnected pores, and wherein the bonded particles are sintered polymer particles,
- a barrier layer substantially concentric about the first porous wall, wherein the barrier layer is comprised of a non-porous, liquid impermeable material, and
- a second porous wall substantially concentric about the barrier layer, wherein the second porous wall has an open porous structure defining a plurality of interconnected pores in fluid communication with one another, wherein the second porous wall is comprised of bonded particles defining the interconnected pores, wherein the bonded particles are sintered polymer particles, and wherein the barrier layer substantially precludes fluid communication laterally between the first porous wall and the second porous wall;
- and
- a therapy device adapted to be in fluid communication with the porous conduit, comprising:
- a reduced-pressure source, a fluid instillation source, and a pressure sensor, wherein the reduced-pressure source is in fluid communication with the central lumen, the fluid instillation source is in fluid communication with the first porous wall, and wherein the pressure sensor is in fluid communication with the second porous wall.
