Laminar construction negative pressure wound dressing including bioabsorbable material
First Claim
Patent Images
1. A negative pressure wound dressing system comprising:
- a bioabsorbable wound bed layer;
an atmospheric barrier layer disposed over the bioabsorbable wound bed layer;
a seal connecting the atmospheric barrier layer with skin surrounding the wound to seal the wound from atmospheric pressure; and
a negative pressure generating system having a device located within the wound under the atmospheric barrier layer to apply negative pressure to the wound.

Abstract
A laminated negative pressure wound dressing system and method is described. The wound dressing is disposed in the wound in layers including at least one bioabsorbable layer that contacts the wound bed, a bioabsorbable fluid communicating layer, an atmospheric barrier layer, and a tube for applying a negative pressure to the wound bed. Ingrowth of granulation tissue into the bioabsorbable wound bed layer does not need to be inhibited as the bioabsorbable material need not be removed during dressing changes. A kit containing the components of the wound dressing system is also disclosed as well as a method for applying the dressing.

30. A method of treating a wound having a wound bed with a negative pressure dressing comprising:
-
disposing a bioabsorbable wound bed layer into the wound bed;
covering the bioabsorbable wound bed layer with an atmospheric barrier layer;
sealing the atmospheric barrier layer to seal the wound from atmospheric pressure;
disposing a negative pressure device in the wound under the atmospheric barrier layer; and
applying negative pressure to the wound through the negative pressure device to lower the pressure within the wound to a level that is less than atmospheric pressure. - View Dependent Claims (31, 32, 33, 34, 35, 36)
