Publication number: 20080213344Abstract: This invention is directed to advanced hemorrhage control wound dressings, and methods of using and producing same. The subject wound dressing is constructed from a non-mammalian material for control of severe 5 bleeding. The wound dressing for controlling severe bleeding is formed of a biomaterial comprising chitosan, a hydrophilic polymer, a polyacrylic polymer or a combination thereof, The kind of severe, life-threatening bleeding contemplated by this invention is typically of the type not capable of being stanched when a conventional gauze wound dressing is applied with conventional 10 pressure to the subject wound. The wound dressing being capable of substantially stanching the flow of the severe life-threatening bleeding from the wound by adhering to the wound site, to seal the wound, to accelerate blood clot formation at the wound site, to reinforce clot formation at the wound site and prevent bleed out from the wound site, and to substantially prohibit the flow of 15 blood out of the wound site.Type: ApplicationFiled: April 18, 2008Publication date: September 4, 2008Inventors: Simon J. McCarthy, Kenton W. Gregory, William P. Wiesmann, Todd D. Campbell

Publication number: 20080146984Abstract: An aqueous solution of polyacrylic acid is placed in a mold, frozen, and freeze-dried to form a sponge-like polyacrylic acid structure. The sponge-like polyacrylic acid structure is compressed by the application of heat and pressure to reduce the thickness and increase the density of the sponge-like polyacrylic acid structure to form a densified polyacrylic acid structure. The densified polyacrylic acid structure is preconditioned by heating to form a wound dressing. The wound dressing can be applied to control severe, life-threatening bleeding from a wound at a wound site of a person.Type: ApplicationFiled: December 17, 2007Publication date: June 19, 2008Inventors: Todd D.

Patent number: 7181264Abstract: Intense environmental or working conditions can impede an individual's evaporative cooling mechanism normally responsible for thermoregulation during exercise or exertion. Non-invasive physiological monitoring capabilities are needed to more precisely define the cardiovascular responses and identify markers of impending failure of compensatory mechanisms prior to collapse or onset of irreversible pathology. The oxymetry method and system of the present invention provides non-invasive, continuous remote monitoring and analysis of cardiovascular and pulmonary function that overcomes accuracy and monitoring deficiencies of current oximetry systems.Type: GrantFiled: March 12, 2003Date of Patent: February 20, 2007Assignee: Sekos, Inc.Inventors: William P.

Patent number: 6519485Abstract: A system for assessing organ function couples light emitters into an optical fiber delivery assembly of which the tip extends to or into an internal organ and illuminates tissue; the device senses temperature at the tip, and a collection fiber collects light scattered, reflected or emitted by the surrounding tissue. Control and processing modules drive the laser diodes and process return spectral signals, e.g., to assess metabolic activity and detect onset of shock. A prototype uses four laser diodes with peaks at 735, 760, 805 and 890 nm, with a front end splitter providing a reference beam to a photo detector for normalizing detection output and correcting the signal samples. The device may include a plurality of laser diodes and may select subsets of the sources to tailor spectral illumination to different target enzymes, metabolites or other compounds.Type: GrantFiled: December 13, 2000Date of Patent: February 11, 2003Assignee: The General Hospital CorporationInventors: William P. Wiesmann, Adrian Richard Urias, Jill Uyeno, Adrian Prokop, Jason Milne, Kristopher Jarka, Farbod Ghassemi

Publication number: 20020072661Abstract: A system for assessing organ function has a plurality of light emitters of distinct spectral characteristics are coupled into a percutaneous fiber delivery assembly with a tip extending to or into an internal organ to illuminate organ tissue. The assembly includes a delivery optical fiber, and a collection fiber that collects and returns light scattered, reflected or emitted by the surrounding tissue to a detector at the proximal end. The device also senses temperature at the tip. Control and processing modules drive the laser diodes and process the return signals. The instrument may assess general metabolic activity by detecting light absorption of a linked substance, for example at a peak attributed to deoxygenated hemoglobin and/or at one or more peaks attributed to oxygenated hemoglobin. Preferably, change of a parameter such as pulse oxygen saturation together with one or more other parameters such as temperature are detected to provide an indication of organ function, e.g., the onset of shock.Type: ApplicationFiled: December 13, 2000Publication date: June 13, 2002Inventors: William P.

Patent number: 5415532Abstract: A pump and a method for pumping liquid or fluid through a pair resilient es includes a shuttle block which partially compresses the tubes in a balanced, alternating manner. The resilient tubes are held in a parallel relationship with a predetermined space defined therebetween. Within the predetermined space, a shuttle block is oscillated along the linear axis to partially compress the tubes in an alternating fashion. As one of the two parallel tubes is compressed, fluid is pumped out of the tube and at the same time fluid is drawn into the second tube as the latter tube resumes its original shape. The resilience of both tubes also is used to assist the pumping action in a balanced fashion, thereby providing a pump that has low power consumption and is lightweight.Type: GrantFiled: November 30, 1993Date of Patent: May 16, 1995Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Michael H. Loughnane, William P. Wiesmann, Frederick J. Pearce, George P. Kearney
