Abstract
A repair prosthetic for repairing a hernia is disclosed. In some embodiments, the repair prosthetic includes a patch body, a frame that assists in spreading the patch body from a reduced configuration to an expanded configuration, and a plurality of tethers attached to the patch body at locations between the frame and a periphery of the patch body. In various embodiments, the tethers can be tensioned to mitigate curling or creasing in the patch body to flatten the patch to facilitate attachment to tissue.
Claims28
A prosthetic comprising:
- a patch body having a periphery;
- a frame attached to the patch body, wherein the frame assists in spreading the patch body from a reduced configuration to an expanded configuration, and wherein the frame includes one or more apertures;
- and
- a plurality of tethers, wherein each of the plurality of tethers is attached to the patch body at an attachment location with the patch body located radially outward from the frame, and wherein a portion of each of the plurality of tethers extends through at least one of the one or more apertures, and wherein pulling on the plurality of tethers through the one or more apertures in a direction away from the patch body tensions the plurality of tethers to spread the patch body.
A prosthetic comprising:
- a patch body having a periphery;
- a frame attached to the patch body, wherein the frame assists in spreading the patch body from a reduced configuration to an expanded configuration, and wherein the frame includes one or more apertures;
- and
- a plurality of tethers attached to the patch body at attachment locations between the frame and the periphery of the patch body, wherein at least two of the plurality of tethers are located on opposing sides of the patch body, and wherein a portion of each of the plurality of tethers extends through at least one of the one or more apertures, and wherein pulling on the plurality of tethers through the one or more apertures in a direction away from the patch body tensions the plurality of tethers to spread the patch body.
A method of repairing a hernia defect, the method comprising:
- delivering a prosthetic for repairing a hernia defect in a reduced configuration through an opening into a patient, the prosthetic includes a patch body having a periphery;
- tensioning a plurality of tethers attached to the patch body at attachment locations between a frame attached to the patch body and the periphery of the patch body, wherein a portion of each of the plurality of tethers extends through at least one of one or more apertures formed in the frame, and wherein pulling on the plurality of tethers through the one or more apertures in a direction away from the patch body tensions the plurality of tethers to spread the patch body;
- and
- spreading the patch body to an expanded configuration about the hernia defect with the frame and plurality of tethers.
