Surgical pads and spacers
A surgical pad can comprise a flexible pad portion configured to be positioned over an opening in a target tissue. A plurality of elongate ribs can be distributed across a surface of the flexible pad portion oriented away from the target tissue and can be coupled to the flexible pad portion. A surgical pad can comprise a central opening configured to be aligned with an opening in a target tissue, and a plurality of edge openings distributed around an outer edge portion. A method can comprise positioning a spacer between a target tissue and a surgical pad to adjust the tension of surgical cords secured to surgical pad. A method can comprise positioning a spacer between a surface of a surgical pad oriented away from a target tissue and portions of surgical cords secured over the surface of the surgical pad, to adjust the tension of the surgical cords.
1 . A surgical pad comprising:
a flexible pad portion configured to be positioned over an opening in a target tissue, the flexible pad portion comprising a first surface configured to be oriented toward the target tissue and a second surface configured to be oriented away from the target tissue;
a plurality of designated locations around an outer edge portion of the second surface, each of the plurality of designated locations being configured to couple to corresponding tethers extending from the opening in the target tissue; and
a plurality of elongate ribs associated with the second surface and coupled to the flexible pad portion, the plurality of elongate ribs being disconnected from each other and configured to provide mechanical reinforcement for the flexible pad portion to counter forces exerted upon the flexible pad portion by the corresponding tethers, each of the plurality of elongate ribs comprising a first end at a center portion of the second surface and a second end spaced from a nearest portion of an outer edge of the flexible pad portion, and the surgical pad being configured to assume a reduced profile state to provide the surgical pad in a folded state in which the first end of each of the plurality of elongate ribs are oriented in a first direction and the second end of each of the plurality of elongate ribs are oriented in a second opposing direction.
2 . The surgical pad of claim 1 , wherein the plurality of elongate ribs is arranged in a radially-extending pattern over the second surface.
3 . The surgical pad of claim 1 , wherein the plurality of elongate ribs is distributed evenly across the second surface.
4 . The surgical pad of claim 1 , wherein each of the plurality of elongate ribs is at least one of a solid rib, a linear rib, and a cylindrical rod.
5 . The surgical pad of claim 1 , wherein the plurality of elongate ribs is sutured to the flexible pad portion.
6 . The surgical pad of claim 1 , wherein the flexible pad portion comprises a plurality of fasteners extending from the second surface and corresponding portions of each of the plurality of elongate ribs are configured to be inserted between a respective fastener and the second surface to couple the plurality of elongate ribs to the flexible pad portion.
7 . The surgical pad of claim 1 , wherein the plurality of designated locations is evenly distributed around the outer edge portion of the second surface.
8 . The surgical pad of claim 1 , wherein the plurality of designated locations comprises a designated location between each respective second end of each of the plurality of elongate ribs and a corresponding nearest portion of the outer edge of the flexible pad portion.
9 . The surgical pad of claim 1 , wherein the plurality of designated locations is between the second ends of the plurality of elongate ribs.
10 . The surgical pad of claim 1 , wherein the flexible pad portion has a circular shape.
11 . The surgical pad of claim 1 , wherein the flexible pad portion comprises a non-biodegradable cross-linked tissue.
12 . The surgical pad of claim 11 , wherein the plurality of elongate ribs comprises a non-biodegradable material.
13 . The surgical pad of claim 1 , wherein the plurality of elongate ribs is arranged in a radial pattern and the surgical pad assumes an umbrella configuration in the reduced profile state.
14 . A surgical pad comprising:
a flexible pad portion comprising a first surface and a second opposing surface and configured to be positioned over an opening in a target tissue, the flexible pad portion transformable from a folded configuration to an unfolded configuration; and
a plurality of elongate ribs configured to provide mechanical reinforcement for the flexible pad portion and associated with a surface of the flexible pad portion configured to be oriented away from the target tissue, the plurality of elongate ribs being disconnected from each other and each comprising a first end oriented toward a center portion of the surface and a second end oriented away from the center portion and spaced from a nearest portion of an outer edge of the flexible pad portion, the first end of each of the plurality of elongate ribs being configured to be oriented proximally and the second end of each of the plurality of elongate ribs being configured to be oriented distally with the flexible pad portion in the folded configuration.
15 . The surgical pad of claim 14 , wherein the flexible pad portion in the folded configuration comprises a fold along at least one of the plurality of elongate ribs.
16 . The surgical pad of claim 14 , wherein the plurality of elongate ribs is coupled to an outwardly facing surface of the flexible pad portion in the folded configuration.
17 . The surgical pad of claim 14 , wherein a center of the flexible pad portion in the folded configuration forms a point.
