Abstract
Systems, methods and devices are provided for use in a negative pressure wound therapy system for healing a wound in a patient. Various aspects may include an ester-based material adapted to be directly applied to the wound, such as a smooth muscle fistula, without substantially damaging tissue in the wound during dressing changes. The ester-based material may have an affinity for the wound bed surface and/or wound fluid. In addition, various aspects may include a device adapted to close the wound, such as a smooth muscle fistula.
Claims20
A wound dressing adapted to be applied to a wound bed including a smooth muscle fistula in a negative pressure treatment system, the wound dressing comprising:
- a wound-side layer comprising a first foam adapted to be placed directly against the wound bed and to contact smooth muscle without causing substantial cellular disruption or damage in the negative pressure environment, the first foam comprising an ester-based material having pores with a width of about 0.1 μm to about 50 μm;
- an intermediate layer adjacent the wound-side layer and comprising a second foam having pores larger than the pores of the ester-based material;
- and
- an occlusive layer adjacent the intermediate layer and opposite the wound-side layer.
A wound dressing adapted to be applied to a wound bed including a smooth muscle fistula in a negative pressure treatment system, the wound dressing comprising:
- a wound-side layer adapted to be placed directly against the wound bed and to contact smooth muscle without causing substantial cellular disruption or damage in the negative pressure environment, the wound-side layer comprising an ester-based material having pores with a width of about 0.1 μm to about 50 μm;
- an intermediate layer adjacent the wound-side layer and comprising a foam having pores the same size or larger than the pores of the first ester-based material;
- and
- an occlusive layer adjacent the intermediate layer and opposite the wound-side layer.
A negative pressure treatment system adapted to treat a wound bed including a smooth muscle fistula, the negative pressure treatment system comprising:
- a wound dressing comprising:
- a wound-side layer adapted to be placed directly against the wound bed and to contact smooth muscle without causing substantial cellular disruption or damage in the negative pressure environment, the wound-side layer comprising an ester-based material having pores with a width of about 0.1 μm to about 50 μm;
- and
- an intermediate layer adjacent the wound-side layer and comprising a foam having pores the same size or larger than the pores of the ester-based material;
- an occlusive layer adjacent the wound dressing opposite the wound bed;
- and
- a vacuum pump configured to apply negative pressure to the wound dressing, thereby withdrawing wound fluid from the wound bed.
