Abstract
A surgical patch system for closing a wound includes a first surgical patch, a second surgical patch, a cord operably associated with the first and second surgical patches, and a port operably associated with the second surgical patch. The first surgical patch is positionable adjacent internal tissue of an underlying tissue site of an open wound. The second surgical patch is positionable adjacent external tissue relative to the underlying tissue site of the open wound. The external tissue is adjacent the internal tissue. The cord is configured and dimensioned to interconnect the first and second surgical patches. The port is positioned to enable the application of negative pressure to the open wound.
Claims18
A surgical patch system for closing a wound, comprising:
- a first surgical patch positionable adjacent internal tissue of an underlying tissue site of an open wound;
- a second surgical patch positionable adjacent external tissue relative to the underlying tissue site of the open wound, the external tissue being adjacent the internal tissue;
- a cord operably associated with the first and second surgical patches, the cord configured and dimensioned to interconnect the first and second surgical patches;
- a port operably associated with the second surgical patch and positioned to enable the application of negative pressure to the open wound, wherein the port includes a one-way valve;
- and
- a vacuum source selectively securable to the port and dimensioned to apply negative pressure between the first and second surgical patches to seal the open wound between the first and second surgical patches.

- a first surgical patch positionable adjacent internal tissue of an underlying tissue site of an open wound;
- a second surgical patch positionable adjacent external tissue relative to the underlying tissue site of the open wound, the external tissue being adjacent the internal tissue;
- a delivery tube configured and dimensioned to permit reception and passage of the first surgical patch into the underlying tissue site;
- a cord operably associated with the first and second surgical patches, the cord configured and dimensioned to interconnect the first and second surgical patches;
- a port operably associated with the second surgical patch and positioned to enable the application of negative pressure to the open wound, wherein the port includes a one-way valve;
- and
- a vacuum source selectively securable to the port and dimensioned to apply negative pressure between the first and second surgical patches to seal the open wound between the first and second surgical patches.

- a cord operably associated with the first and second surgical patches, the cord configured and dimensioned to interconnect the first and second surgical patches;
- a port defining an opening, the port fixedly secured to the second surgical patch and extending from an outer surface of the second surgical patch, the port including a one-way valve that extends from an inner surface of the port into the opening to block the opening, the one-way valve being movable in response to a passage of the cord through the opening and being movable in response to passage of negative pressure through the opening;
- and a vacuum source securable to the port to apply negative pressure through the one-way valve to seal the open wound between the first and second surgical patches.
