20110251638 | IMPLANTABLE BIODEGRADABLE WOUND CLOSURE DEVICE AND METHOD - A device and methods for maintaining the alignment of the edges of a wound in the fascia and associated layers are disclosed. The device includes a biodegradable implantable device, an insertion tool and a compression tool. The biodegradable implantable device includes a biodegradable compressible structure of such size and shape that it is capable of maintaining the alignment of the edges of the wound. One or more embodiments of the biodegradable compressible structure include a structure with a surface to make contact with the inner surface of a wound, another structure with a surface to contact with the outer surface of a wound, a means for connecting the two bases such as a screw or snap fitting, and a means for detachably connecting the compressible structure to an insertion tool such as grooves or a slotted ring. The insertion tool provides a means for inserting the biodegradable compressible structure into the wound and a means for exerting a force on the biodegradable compressible structure such that the two biodegradable bases move closer to each other and compress the fascia and associated layers of the abdominal wall. | 10-13-2011 |

20140081319 | Implantable biodegradable wound closure device. - A biodegradable device for maintaining the alignment of the edges of a trocar defect, consisting of two bases joined by a connector, a first base to be positioned below the defect and a second base above. The first base has a threaded hole from its upper surface but not through the lower surface. The connector attached to the bases such that there is a hole aligned with the threaded hole in the first base allowing a device to mate with the threads in the first base. The second base has a hole aligned with the hole in the connector and wide enough to allow a device to mate with the threads in the first base. The device is arranged so the distance between the lower surface of the second base and upper surface of the first base holds but does not compress the fascia around the trocar defect. | 03-20-2014 |

20130012987 | IMPLANTABLE BIODEGRADABLE WOUND CLOSURE DEVICE AND METHOD - An implantable biodegradable device consisting of an inner button attached to a cylindrical segment, and an outer button attached to a retainment feature. The cylindrical segment is threaded on one end, with a surface groove. The retainment feature consists of radial strips with bent ends. The diameter of the radial strips is slightly larger than the outer diameter of the cylinder. The bent ends fit into the groove. An insertion tool can attach to the threads in the cylinder and push the inner button through a wound, then, holding the inner button in place, push the outer button toward the inner button until the bent ends engage with the groove. The top of the threaded end of the cylindrical segment is adjacent to the back surface of the outer button when the bent ends of the retainment feature are engaged with the groove. | 01-10-2013 |
