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.
Claims64
A method comprising:
- generating a protocol using patient data, wherein the protocol includes at least one target site and a topographical map of fractional skin resections configured for application at the at least one target site;
- positioning at the target site a carrier including a scalpet assembly comprising at least one scalpet and a depth control device, wherein the at least one scalpet includes a tube comprising a hollow region and a sharpened distal end configured to penetrate tissue at the at least one target site;
- performing fractional resection by circumferentially incising skin pixels at the at least one target site using the scalpet assembly, and controlling a depth of penetration of the incising using the depth control device;
- and
- removing the fractionally resected skin pixels from the at least one target site via an orifice in the at least one scalpet.

A method comprising:
- generating a protocol including a target site and a topographical map of fractional skin resections configured for application at the target site;
- positioning at the target site a carrier comprising a plurality of scalpets, wherein each scalpet includes a scalpet shaft comprising a proximal end, and a distal end configured to penetrate tissue at the at least one target site, wherein at least one region of the scalpet shaft adjacent the distal end is configured to pass tissue received through the distal end out of an orifice of the scalpet shaft;
- performing fractional resection by incising skin pixels at the target site with the plurality of scalpets;
- and
- removing at least one of the fractionally resected skin pixels and fat from the target site.

A method comprising:
- configuring a resection device to include a scalpet assembly comprising a scalpet array and a depth control device, wherein the scalpet array includes a plurality of scalpets, and each scalpet includes a tube comprising a hollow region and a distal end configured to penetrate tissue at a target site, wherein the distal end includes at least one of a sharpened region and a blunt region, wherein the depth control device is configured to control a depth of the penetration of the scalpet array into the tissue;
- configuring the resection device for operation at the target site according to a protocol including a map of fractional resections;
- configuring the resection device for performing the fractional resections by incising skin pixels at the target site;
- and
- configuring the resection device for removing at least one of the fractionally resected skin pixels and fat from the target site.

- configuring the resection device for performing the fractional resections by incising skin pixels at the target site according to the protocol;
- and
- configuring the resection device for removing at least one of the fractionally resected skin pixels and fat from the target site.
