  • Patent number: 11109887
    Abstract: Embodiments include devices and methods configured to fractionally resect skin and/or fat. Fractional resection is applied as a stand-alone procedure in anatomical areas that are off-limits to conventional plastic surgery due to the poor tradeoff between the visibility of the incisional scar and amount of enhancement obtained. Fractional resection is also applied as an adjunct to established plastic surgery procedures such as liposuction, and is employed to significantly reduce the length of incisions required for a particular application. The shortening of incisions has application in both the aesthetic and reconstructive realms of plastic surgery.

  • Patent number: 11076844
    Abstract: A suture anchor assembly, adapted to be attached to a bone, that includes an anchor, which has an undeployed state in which it is soft and flexible, and which can be deployed into a deployed state which is compacted and hard, relative to the undeployed state, and defining a hold region, where the anchor is optimally held as the anchor is deployed. Also, one or more deployment strands are engaged into the anchor and extend out of the anchor, and wherein, when the anchor is in the undeployed state, holding the anchor at the hold region and pulling on the deployment strands compacts the anchor into the deployed state. Accordingly, the anchor can be introduced into a hole in bone and held in place at the hold region, as it is transformed into the deployed state by pulling on the deployment strands, thereby anchoring the anchor in the hole.
