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.

Publication number: 20210030457Abstract: In one aspect, the present invention provides a method of cooling to produce selective disruption of visceral fat tissue in a non-infant human subject comprising infusing a cooled fluid into the abdominal or peritoneal cavity, or into other parts of the body containing visceral fat, to cool the proximal tissue sufficiently to selectively disrupt lipid-rich cells therein, for example, to promote subsequent damage and absorption of lipid-rich cells by the body without producing unwanted effects in non-lipid-rich cells; e.g., without injury to internal organ tissues that could otherwise produce life-threating risks. The cooled fluid can be infused using a catheter arrangement. The cooled fluid can be retained within the abdominal category for a particular duration, and then drained using the catheter arrangement. In certain embodiments, the cooled fluid can be simultaneously introduced into the abdominal cavity and drained therefrom.Type: ApplicationFiled: March 10, 2020Publication date: February 4, 2021Applicant: The General Hospital CorporationInventors: Matthew M.

Publication number: 20190350610Abstract: A tissue harvesting and wound closing device includes first and second actuator strip guides of a strip that are slideable along first and second panel guides of a panel, respectively. A first section of a base of the actuator strip has a substantially uniform width between the first and the second actuator strip guides. A second section of the base has a gradually decreasing width between the first and second actuator strip guides. A third second section of the base has a substantially uniform width between the first and second actuator strip guides that is smaller than the first width. When the actuator strip is pulled, the first and second actuator guides slide along the first and second panel guides, respectively, to cut a strip of tissue strip creating an open wound, and a panel pulls proximal tissue on opposite sides of the open wound to close the wound.Type: ApplicationFiled: January 23, 2018Publication date: November 21, 2019Inventors: Alexander G.
