Patent number: 6641601Abstract: A tissue treatment apparatus is provided which includes a thermally conductive bandage, a heater in thermal contact with the bandage over a tissue treatment area, a heat spreading means acting between the heater and the bandage for laterally spreading heat transferred from the heater to the bandage in order that heat be substantially uniformly distributed across the bandage.Type: GrantFiled: January 29, 2001Date of Patent: November 4, 2003Assignee: Augustine Medical, Inc.Inventors: Scott D. Augustine, Keith J. Leland, John P. Rock, Donald E. Stapf

Patent number: 6585670Abstract: A wound treatment apparatus is provided which includes a thermally conductive bandage, a heater in contact with the bandage over a wound treatment area, and an adhesive attachment device for maintaining thermally conductive contact between the heater and the bandage. The bandage and heater together have a low profile so as to be convenient for the patient and are flexible so as to conform to the shape of the wound and to the contours of the skin surrounding the wound. The attachment device is fashioned so as to have less pull strength than an adhesive holding the bandage to the person's body so that the heater can be easily removed without disturbing the attachment of the bandage to the person's body. The bandage is provided with a polymeric film for maintaining moisture at the wound site as well as enhancing the utility of the attachment device.Type: GrantFiled: July 15, 2002Date of Patent: July 1, 2003Assignee: Augustine Medical, Inc.Inventors: Scott D. Augustine, Keith J. Leland, John P. Rock, Donald E. Stapf

Patent number: 6580012Abstract: A non-contact wound treatment device suitable for releasable attachment to a patient's skin surface over a selected wound area in a non-contact position relative to the selected wound area, the wound treatment device comprising an attachment portion suitable for releasable attachment with the patient's skin surface, having an inner perimeter for defining the selected wound area, a wound treatment portion with a substantially planar wound cover and a support member supporting the wound cover, and a transition portion with a membrane connecting the wound treatment portion to the attachment portion, the membrane extending around the outer perimeter of the support member and attached to the attachment portion between the inner and outer perimeter of the attachment portion.Type: GrantFiled: April 11, 2000Date of Patent: June 17, 2003Assignee: Augustine Medical, Inc.Inventors: Scott D. Augustine, Randall C. Arnold, Gregory P. Hamlin, Donald E. Stapf, Keith J. Leland

Patent number: 6573420Abstract: A tissue treatment device suitable for use on an extremity, such as a hand or foot, includes a cover formed as a bag, sac, or pouch, and a support member disposable within the cover to support a portion of the cover off of, and out of contact with, tissue to be treated. The cover has an open end with one or more attachment portions disposed thereon for attachment to a limb whose extremity is received in the cover.Type: GrantFiled: July 18, 2001Date of Patent: June 3, 2003Assignee: Augustine Medical, Inc.Inventors: Donald Stapf, Scott D. Augustine, Keith J. Leland

Patent number: 6570050Abstract: A bandage for autolytic debridement includes a fluid-impermeable enclosure having a sidewall forming a margin defining an opening, and a skin-facing surface that surrounds the opening. An attachment means is disposed on the skin-facing to attach the enclosure to the skin, with the margin extending outside of and surrounding at least the bed of a wound. When the enclosure is attached to the skin it creates a closed, fluid-impermeable chamber over a wound, substantially without contacting the wound. The bandage includes a fluid absorbent material disposed in the fluid-impermeable enclosure at or near the continuous margin, and out of the opening. The fluid absorbent material is thus positioned to receive and retain exudated fluid that originates in the wound, thereby by promoting autolytic debridement. The closed, fluid-impermeable chamber maintains a near-100% humid atmosphere about the wound, thereby promoting healing of the wound.Type: GrantFiled: July 25, 2001Date of Patent: May 27, 2003Assignee: Augustine Medical, Inc.Inventors: Scott D. Augustine, Keith J. Leland, John P. Rock, Donald E. Stapf

Publication number: 20030097164Abstract: A warming pack includes a container in the form of a pack, pouch, or bag in which reactants for an exothermic chemical reaction are distributed in one or more flexible matrixes that prevent them from shifting. The rate of the reaction is controlled and the reaction is thermally buffered in order that heat be produced at a constant rate.Type: ApplicationFiled: July 25, 2002Publication date: May 22, 2003Inventors: Donald Stapf, Keith J. Leland

Publication number: 20020193739Abstract: A fluid warming cassette with a stiffening frame structure and an integral handle is provided to support a parenteral fluid container. The fluid container is desirably thin to minimize heat exchange inefficiencies. The frame structure permits the thin fluid container to be inserted into the narrow space between fixed position warming plates of a warming unit. The frame structure has a quadrilateral shape with sides and ends. The fluid container is attached, at its periphery to the sides and ends of the frame structure, within the quadrilateral shape. Part of the frame structure is formed into a handle to assist in both the insertion and removal of the cassette from a warming unit.Type: ApplicationFiled: July 31, 2002Publication date: December 19, 2002Inventors: Scott D.

Publication number: 20020169406Abstract: A tissue treatment device has a flexible treatment portion that includes one or more parts and holes arranged in an openwork. A treatment area is defined in the openwork. The treatment portion is deployed such that the treatment area is positioned over tissue to be treated. The openwork minimizes contact between the tissue treatment device and the tissue being treated. A flexible cover is secured against the flexible treatment portion to close the holes and form a treatment volume in the openwork. The minimal contact between the tissue treatment device and the tissue being treated promotes a desired clinical objective.Type: ApplicationFiled: May 10, 2002Publication date: November 14, 2002Inventors: Donald Stapf, Keith J.
