Publication number: 20130345614Abstract: The invention provides a device for extracorporeal photo-isomerization of bodily fluid containing bilirubin. The bodily fluid derives from a patient suffering from an elevation of unconjugated bilirubin. The device includes a sterile tubing which accesses the patient's bodily fluids (especially blood), routes the fluid into an extracorporeal chamber within which irradiation of bodily fluids takes place, and returns bodily fluids to the patient. Bodily fluids are continuously circulated through a single length of sterile tubing using an adjustable pump to regulate the flow, and as the fluid passes into the extracorporeal chamber it is irradiated by blue light within the chamber with an emission wavelength range of approximately 450 to 530 nm. This irradiation induces a photochemical reaction in bilirubin that changes its structure and facilitates improved excretion of bilirubin once it is returned to the patient. The extracorporeal photo-isomerization turns the bilirubin into a more readily excreted form.Type: ApplicationFiled: June 24, 2013Publication date: December 26, 2013Inventor: Viraj P. Mane

Patent number: 7988951Abstract: Transimmunization methods incorporating skin immunologic challenges are described for either selectively suppressing the immune response of recipients of transplanted tissue or cells or monitoring induced anti-cancer immunity. In one embodiment, skin from the transplant donor is allografted to the transplant recipient to induce an immunological response to the transplanted skin. A quantity of blood is taken from the recipient and treated to render the T cells in the blood apoptotic and to induce differentiation of blood monocytes into dendritic cells. The treated blood is incubated and administered to the recipient to induce formation of suppressor T cell clones which reduce the number of T cells attacking the transplanted tissue or organ. This tolerogenic approach can be complemented by also feeding the immature dendritic cells apoptotic or necrotic cells from the organ donor.Type: GrantFiled: November 30, 2009Date of Patent: August 2, 2011Assignee: Yale UniversityInventor: Richard Leslie Edelson

Patent number: 7938792Abstract: An extracorporeal therapy machine removes blood from a patient in order to treat the blood and then return the blood to the patient. If the removal needle or the return needle is dislodged and blood is not returned, the patient may suffer a great blood loss. A new technique for detecting dislodgement uses the normal, initial values of a plurality of parameters of the patient and the therapy machine to set criteria or limits for an alarm, and then adjusts those criteria based on the later values of those parameters as they change during one therapy or over several therapies experienced by the patient.Type: GrantFiled: October 1, 2007Date of Patent: May 10, 2011Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventors: Rodolfo G. Roger, Michael E. Hogard, Joel Tejedor

Patent number: 7914479Abstract: The present invention is directed to a photolytic artificial lung. The photolytic artificial lung converts water to oxygen for blood absorption, regulates pH, the removes carbon dioxide, and co-produces electrical power is disclosed. The photolytic artificial lung includes a photolytic cell where all of the chemical reactions occur. The photolytic cell disclosed herein can also be used to direct chemical reactions in organs other than the lung. Also disclosed herein is a gas sorption device for removing carbon dioxide from the system by chemical sorption.Type: GrantFiled: September 13, 2004Date of Patent: March 29, 2011Assignees: Battelle Memorial Institute, Pharos, LLCInventors: Bruce F.

Patent number: 7850634Abstract: An improved method for separating whole blood into components and collecting a desired blood component. The method allows a desired blood component to be subjected to centrifugal forces within a separator for prolonged periods of time, yielding a cleaner cut and higher yield of the desired blood component. Whole blood is drawn from a source and pumped into a separator, the undesired blood components are removed from the separator at rates so as to build up the desired blood component in the separator. The desired blood component is only removed after a predetermined amount of the desired blood component has built up in the separator. It is preferred that the desired blood component be buffy coat and that the method be used to perform photopheresis treatments. In another aspect, the invention is a method of performing a full photopheresis treatment to treat diseases in a reduced time, preferably less than about 70 minutes, and more preferably less than about 45 minutes.Type: GrantFiled: December 19, 2006Date of Patent: December 14, 2010Assignee: Therakos, Inc.Inventor: Dennis Briggs

Patent number: RE42354Abstract: An apparatus and method for modifying viruses and bacteria in a closed loop system that irradiates the fluid multiple times through the same channel. The apparatus consists of a cuvette, an irradiation station, a peristaltic pump, and a bottle. A plurality of power control switches controls the operation of the apparatus. This includes an on/off power switch, an on/off pump control, and a ultraviolet light control switch. A timer is provided to regulate the time period the cuvette is exposed to the ultraviolet radiation within the irradiation station. A cover is provided to enable the cuvette to be used and exposed to ultraviolet radiation within an enclosed environment.Type: GrantFiled: February 20, 2008Date of Patent: May 10, 2011Inventor: Robert E.
