Abstract
The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue grasping elements to apply a wound closing force to the tissue.
Claims17
A wound closure device, comprising:
- a stabilizing structure comprising a plurality of planar support structures, each planar support structure comprising a first plurality of beams intersecting with a second plurality of beams, the plurality of planar support structures being arranged parallel to one another;
- a plurality of spring elements joining adjacent planar support structures, the plurality of spring elements providing for compression of the stabilizing structure so that the planar support structures come closer to one another;
- and
- wherein the planar support structure comprises one or more standoffs located on an outer plane or perimeter.
A wound closure device, comprising:
- a stabilizing structure comprising a plurality of planar support structures, each planar support structure comprising a first plurality of beams intersecting with a second plurality of beams, the plurality of planar support structures being arranged parallel to one another;
- a plurality of spring elements joining adjacent planar support structures, the plurality of spring elements providing for compression of the stabilizing structure so that the planar support structures come closer to one another;
- and
- wherein the planar support structure comprises one or more outer standoffs provided with one or more tissue anchors configured to engage tissue placed into contact with the device.
A wound closure device, comprising:
- a stabilizing structure comprising a plurality of planar support structures, each planar support structure comprising a first plurality of beams intersecting with a second plurality of beams, the plurality of planar support structures being arranged parallel to one another;
- a plurality of spring elements joining adjacent planar support structures, the plurality of spring elements providing for compression of the stabilizing structure so that the planar support structures come closer to one another;
- and
- wherein the plurality of spring elements comprise a first plurality of spring elements located in a first plane perpendicular to the planar support structures, and a second plurality of spring elements located in a second plane perpendicular to both the first plane and to the planar support structures.
