摘要： 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.

摘要： A process and system provides for atraumatic preparation of morselized Tissue Particles (TP)s, such as Full Thickness Skin Graft Particles (FTSGPs), cartilage particles and other organ tissue particles, in a liquid medium. The resultant tissue product may be a suspension of Tissue Particles in an aqueous solution and containing highly viable cells and may be rapidly prepared at bedside or in the operating room and conveniently delivered to a patient through a syringe or similar applicator. The morselized Tissues Particles may be used for surgical applications including wound healing, cosmetic surgery, and orthopedic cartilage repairs.

摘要： A new minimally invasive surgical approach is proposed that contemplates a method and apparatus for tightening lax skin without visible scarring via a device in various surgical procedures such as plastic surgery procedures. In some embodiments, the device is a single use disposable instrument. This approach circumvents surgically related scarring and the clinical variability of electromagnetic heating of the skin and performs small multiple pixilated resections of skin as a minimally invasive alternative to large Plastic surgical resections of skin. This approach can also be employed in areas of the body that are currently off limits to plastic surgery due to the visibility of the surgical scar. In addition, the approach can perform a skin grafting operation by harvesting the transected incisions of skin from a tissue site of a donor onto a skin defect site of a recipient with reduced scarring of the patient's donor site.

摘要： Methods and devices for management of fluids during skin graft transplantation are disclosed. In one aspect of the invention, absorbent substrates for transplanting skin grafts are disclosed having a surface adapted to contact at least one excised skin graft and engage said graft for removal from a donor site; a sealing member at least partially surrounding an absorbent material disposed within the enclosure; wherein at least a portion of the skin-contacting surface is porous and in fluid communication with the absorbent layer to capture fluids.

摘要： A skin graft mesher including a cutting roller and a guide roller rotatably mounted to a fixture. A skin graft may be advanced through the mesher between the rollers to form a pattern of perforations in the skin graft. The cutting roller includes cutting rings disposed on an axle and rotatable therewith. The cutting roller further includes a tissue clearing structure positioned between adjacent cutting rings with the axle extending through the tissue clearing structure and rotatable relative to the tissue clearing structure. The tissue clearing structure may clear tissue from between adjacent cutting rings during operation of the skin graft mesher. The tissue clearing structure may be eccentrically rotated about the axle between adjacent cutting rings with the tissue clearing structure extending radially outward beyond the outer diameter of the cutting ring around less than the entire outer circumference of the cutting ring.

摘要： Skin graft harvesting systems and methods are disclosed that utilize sensors to automate the harvesting of skin grafts or assist a user in deciding when the skin graft is ready to be harvested. Such systems and methods can reduce the burden of visual observation and ensure greater reliability and consistency of the grafts. The invention is particularly useful with harvesters that rely upon suction and/or heating to raise a plurality of small or “micro” blisters simultaneously.

摘要： Autografts are produced using material harvested from the patient without creation of a new wound. For example, material is harvested from the patient's very wound to which the autograft is to be applied.
