Abstract
The present disclosure features devices, kits, and methods for providing dressings and uses thereof for localized and contained application of a biomaterial to a subject (e.g., the skin and/or a wound) for medical and/or cosmetic purposes. The devices disclosed herein can be used to promote drying and coagulation of the biomaterial, thereby forming a biomaterial dressing that remains applied upon removal of the wound dressing.
Claims31
A wound dressing for applying a biomaterial to a subject, the wound dressing comprising:a first layer comprising a first opening and a plurality of first pores having a first width;
- a second layer comprising a second opening and one or more second pores having a second width;_and an injection port attached to a distal surface of the second layer with a first adhesive and a second adhesive, wherein the first adhesive is spaced apart from the second adhesive,wherein the first layer is configured to be between the second layer and the subject when the wound dressing is applied to the subject, the first opening is at least partially aligned with the second opening to allow passage of the biomaterial from the injection port through the first layer and the second layer, and the second width is larger than the first width.
(canceled)
A wound dressing for applying a biomaterial to a subject, the wound dressing comprising:a first layer comprising a first opening and a plurality of first pores having a first width;a second layer comprising a second opening, one or more second pores having a second width, and a flap configured to pivot relative to the second opening;
- andan injection port releasably attached to a distal surface of the second layer with a first adhesive and a second adhesive, wherein the first adhesive and the second adhesive are spaced apart, and the injection port is configured to introduce the biomaterial through the first opening and the second opening,
- wherein the first layer is configured to be between the second layer and the subject when the wound dressing is applied to the subject, the first opening is at least partially aligned with the second opening, the flap are configured to provide one-way passage of the biomaterial through the second opening, the second width is larger than the first width, and the one or more second pores are uncovered distally and directly open to the atmosphere.
A method comprising:applying a wound dressing at least partially over a wound;
- injecting a biomaterial, via an injection port attached to a distal surface of the wound dressing with an adhesive, through a first opening of a first layer of the wound dressing and a second opening of a second layer of the wound dressing to the wound, wherein air is vented through a plurality of first pores of the first layer and one or more second pores of the second layer;andremoving the injection port along with the adhesive from the distal surface of the wound dressing after injecting the biomaterial.
22-23. (canceled)
A wound dressing for applying a biomaterial to a subject, the wound dressing comprising:a first layer comprising a first opening and a plurality of first pores having a first width;a second layer comprising a second opening and one or more second pores having a second width;an adhesive on a proximal surface of the second layer;
- andan insert positioned between the adhesive and the first layer,wherein the first layer is configured to be between the second layer and the subject when the wound dressing is applied to the subject, the first opening is at least partially aligned with the second opening to allow passage of the biomaterial through the first layer and the second layer, the second width is larger than the first width, and the insert is configured to facilitate release of the second layer from the first layer.
