Publication number: 20240115292Abstract: Exemplary embodiments of apparatus and method for obtaining one or more portions of biological tissue (“micrografts”) to form grafts are provided. For example, a hollow tube can be inserted into tissue at a donor site, and a pin provided within the tube can facilitate controlled removal of the micrograft from the tube. Micrografts can be harvested and directly implanted into an overlying biocompatible matrix through coordinated motion of the tube and pin. A needle can be provided around the tube to facilitate a direct implantation of a micrograft into a remote recipient site or matrix. The exemplary apparatus can include a plurality of such tubes and pins for simultaneous harvesting and/or implanting of a plurality of micrografts. The harvested micrografts can have a small dimension, e.g., less than about 1 mm, which can promote healing of the donor site and/or viability of the harvested tissue.Type: ApplicationFiled: October 10, 2023Publication date: April 11, 2024Inventors: Richard Rox Anderson, William A. Farinelli, Walfre Franco, Joshua Tam, Fernanda H. Sakamoto, Apostolos G. Doukas, Martin Purschke, Min Yao

Publication number: 20210369502Abstract: The present disclosure is directed to systems and methods that removing exogenous particles from a target region of the skin of a patient. The systems and methods can employ dermal lavage to remove the exogenous particles from the target region. In some instances, the exogenous particles can be residual tattoo ink after a tattoo removal process. A conduit can be sized and dimensioned for insertion into or around the target region to inject an irrigation fluid that defines an irrigation area. The exogenous particles can be suspended in the irrigation fluid. A device can be configured to form one or more channels in the irrigation area so that the exogenous particles are removable from the irrigation area.Type: ApplicationFiled: August 13, 2021Publication date: December 2, 2021Inventors: Lilit Garibyan, Richard Rox Anderson, William Farinelli, Fernanda H.

Publication number: 20200360576Abstract: After a tattoo removal process fragments of the tattoo (pigment particles) may be left in the patient's skin. Pressure can be applied to the patient's skin to move the pigment particles deeper within the patient's skin. The pigment particles can become less visible when they are deeper within the patient's skin.Type: ApplicationFiled: July 31, 2020Publication date: November 19, 2020Inventors: Lilit Garibyan, Richard Rox Anderson, William Farinelli, Fernanda H.

Publication number: 20160030722Abstract: Exemplary methods and devices can be provided for an improved wound dressing that facilitates healing. For example, the dressing can include a membrane that maintains a sterile enclosed volume over the wound. Pressure in the enclosed volume can be reduced by deforming the membrane and compressing a resilient open-cell sponge provided therein, facilitating a relatively unobstructed flow of air out of the enclosed volume. Oxygen and/or moisture can be introduced by a controlled flow of moist oxygen-containing gas into the enclosed volume. An oxygen-producing reaction within the enclosed volume using calcium peroxide or the like can also provide oxygen to the wound site. An external vacuum source that includes compressible foam can also be coupled to the enclosed volume to provide a reduced pressure therein. The external vacuum source can be attached to a user's body to maintain the reduced pressure without use of electricity.Type: ApplicationFiled: March 14, 2014Publication date: February 4, 2016Inventors: RICHARD R.
