Patent number: 6468295Abstract: A treatment device having an attachment portion the first plane, a treatment portion with a cover in a second plane that defines a treatment volume extending between the first and second plane, and a flexible transition portion that connects the attachment portion to the treatment portion. The transition portion attaches to the attachment portion by a first flexible connection and to the treatment portion by a second flexible connection, with a minimum inter-connecting distance being defined by a straight line between a first point on the first flexible connection and a second point, corresponding to the first point, on the second flexible connection. The transition portion's length exceeds the length of the straight line. A flexible, serrated standoff supports the wound cover. An absorptive foam ring that acts between the first plane on the cover has in it a medicament selected from the group including an antibiotic material, an antifungal material, and an antimicrobial material.Type: GrantFiled: March 23, 2001Date of Patent: October 22, 2002Assignee: Augustine Medical, Inc.Inventors: Scott D. Augustine, Randall C. Arnold, Gregory P. Hamlin, Donald E. Stapf

Patent number: 6436063Abstract: 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: January 28, 2000Date of Patent: August 20, 2002Assignee: Augustine Medical, Inc.Inventors: Scott D. Augustine, Keith J. Leland, John P. Rock, Donald E. Stapf

Patent number: 6420623Abstract: 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: July 16, 2002Assignee: Augustine Medical, Inc.Inventors: Scott D.

Patent number: 5837002Abstract: A focal cooling apparatus includes a cooling, or heat sinking, layer over which a layer of compressible, thermally insulating material is disposed. The layer of compressible, thermally insulating material has a surface for supporting a portion of a human (or animal) body. The layer of compressible, thermally insulating material responds to pressure exerted against the surface by exhibiting a thermal resistance between the surface and the cooling layer that varies inversely with the pressure. Means are provided for maintaining the cooling layer at a predetermined temperature below normal human temperature.Type: GrantFiled: August 30, 1996Date of Patent: November 17, 1998Assignee: International Business Machines CorporationInventors: Scott D.
