Abstract
Methods and systems for treating a wound using targeted delivery of magnetically-tagged active agents in combination with negative pressure wound therapy are presented. In particular, a magnetically-active wound insert may be used to attract magnetically-tagged stem cells to a wound site to treat the wound.
Claims17
A wound treatment system for use in treating tissue at a wound site in patient, comprising:
- a wound dressing comprising:
- a drape adapted to be coupled to skin adjacent to the wound such that the drape covers the wound and forms a space between the drape and the wound;
- and
- a wound insert disposed within the space configured to attract a magnetically-tagged therapeutic agent to the tissue and increase exposure of the tissue to the agent, the wound insert comprising a magnetic material;
- and
- a delivery member configured to provide the magnetically-tagged therapeutic agent.

A wound treatment system for treatment of a wound, comprising:
- a wound insert adapted to be disposed adjacent to the wound and configured to attract a magnetically-tagged therapeutic agent to the wound so as to increase exposure of the wound to the agent, the wound insert comprising an open-celled foam member and magnetic particles coated on or dispersed in the foam member;
- a negative pressure source;
- a conduit in fluid communication with the negative pressure source, configured to deliver an instillation fluid to the wound, to remove fluid from the wound, and to apply negative pressure to the wound;
- and
- a delivery member configured to provide the magnetically-tagged therapeutic agent to a site not in the wound.
