Patent number: 8057446Abstract: Methods and devices transmit micromechanical forces locally on the millimeter to micron scale for promoting wound healing. Micromechanical forces can selectively be applied directly to tissue, in some embodiments, by using microchambers fluidically connected to microchannels. Each chamber, or in some cases, group of chambers, may be associated with a valve to control vacuum pressure, positive pressure, liquid delivery, and/or liquid removal from each chamber or group of chambers. Application of embodiments of the invention may shorten wound-healing time, reduce costs of therapy, enable restoration of functional tissue, and reduce the need for more invasive therapies, including surgery.Type: GrantFiled: April 30, 2008Date of Patent: November 15, 2011Assignee: The Brigham and Women's Hospital, Inc.Inventors: Bartholomew J.

Patent number: 7494482Abstract: Methods and devices for transmitting micromechanical forces locally to induce surface convolutions into tissues on the millimeter to micron scale for promoting wound healing are presented. These convolutions induce a moderate stretching of individual cells, stimulating cellular proliferation and elaboration of natural growth factors without increasing the size of the wound. Micromechanical forces can be applied directly to tissue, through biomolecules or the extracellular matrix. This invention can be used with biosensors, biodegradable materials and drug delivery systems. This invention will also be useful in pre-conditioned tissue-engineering constructs in vitro. Application of this invention will shorten healing times for wounds and reduce the need for invasive surgery.Type: GrantFiled: May 15, 2002Date of Patent: February 24, 2009Assignee: The Brigham and Women's Hospital, Inc.Inventors: Dennis P. Orgill, Quentin Gavin Eichbaum, Sui Huang, Chao-Wei Hwang, Donald E. Ingber, Vishal Saxena, Evan Stuart Garfein

Patent number: 6117444Abstract: A resorbable hemostatic agent comprising a delivery component, that aids in the delivery to the wound site, and a microfibrillar hemostatic component that controls bleeding in solid tissue and does not delay or interfere with healing is described. The viscosity of this resorbable hemostatic agent can be changed to allow for easy application at a range of temperatures. The resorbable hemostatic agent of the invention provides a biodegradable, biocompatable hemostatic agent which effectively controls bleeding in bone and other dense tissue without interfering with the subsequent healing of the tissue.Type: GrantFiled: April 10, 1997Date of Patent: September 12, 2000Assignee: Brigham & Women's HospitalInventors: Dennis P.

Patent number: 5716411Abstract: The present invention relates to a method of skin regeneration of a wound or burn in an animal or human. This method comprises the steps of initially covering the wound with a collagen glycosaminoglycan matrix, allowing infiltration of the grafted GC matrix by mesenchymal cells and blood vessels from healthy underlying tissue and applying a cultured epithelial autograft sheet grown from epidermal cells taken from the animal or human at a wound free site on the animal's or human's body surface. The resulting graft has excellent take rates and has the appearance, growth, maturation and differentiation of normal skin.Type: GrantFiled: February 6, 1996Date of Patent: February 10, 1998Assignees: Brigham & Womens Hospital, Massachusetts Institute of Technology, Shriners Hospitals for Crippled ChildrenInventors: Dennis P.

Patent number: 4418691Abstract: This invention comprises the use of centrifugal force to introduce viable cells into a fibrous lattice, as well as fibrous lattices that are seeded with cells by the use of centrifugal force. A variety of fibrous lattices may be seeded by the methods of this invention, such as a highly porous lattice comprising collagen fibers crosslinked with glycosaminoglycan. Before the centrifugation, a piece of intact tissue is harvested from a donor site. It is treated with one or more substances, such as trypsin or collagenase, to dissociate cells from the tissue. The cells are then mixed with an aqueous solution to create an aqueous suspension of cells. A piece of fibrous lattice is placed within a container, referred to herein as a "bucket," that is suitable for rotation by a centrifuge. The aqueous suspension of cells is placed within the bucket, in contact with the lattice. The centrifuge is then rotated.Type: GrantFiled: October 26, 1981Date of Patent: December 6, 1983Assignee: Massachusetts Institute of TechnologyInventors: Ioannis V. Yannas, John F. Burke, Dennis P. Orgill, Eugene M. Skrabut
