Publication number: 20170087181Abstract: This disclosure relates to methods of using nitrite to detoxify stroma-free hemoglobin based blood substitutes. In particular, methods are described for using a blood substitute comprised of about equimolar amounts of nitrite and hemoglobin (e.g., nitrite-metHb) to treat, prevent, or ameliorate diseases of the blood in a subject, or as a blood replacement in a subject.Type: ApplicationFiled: May 4, 2016Publication date: March 30, 2017Applicants: The Government of the U.S.A. as represented by the Secretary of the Department of Health and Human S, The UAB Research Foundation, Wake Forest UniversityInventors: Mark T.

Patent number: 9453526Abstract: Anchor assemblies useful for connecting structures to each other are described. An anchor assembly includes a head member and an anchor. In the fully assembled anchor assembly, the anchor is partially disposed within the head member. During assembly, the proximal end of the anchor can be inserted into an opening defined by a distal end of the head member. A retaining member maintains a portion of the anchor within a portion of the head member after assembly. In an embodiment, a compression member enables movement of the retaining member within the head member to allow insertion of a portion of the anchor and subsequent maintenance of the portion of the anchor within a portion of the head member.Type: GrantFiled: April 30, 2013Date of Patent: September 27, 2016Assignee: DeGen Medical, Inc.Inventors: Craig Black, Rakesh P.

Publication number: 20150224144Abstract: Provided herein is a composition comprising transfusable red blood cells having improved storage capability, wherein a C9 inhibitor has been administered to the composition and thereby the composition has a reduced amount of red blood cell lysis as compared to a control. It is a surprising finding of the present invention that addition of a C9 inhibitor to a blood sample decreases the amount of red cell lysis in the sample over time. Accordingly, the present invention provides red blood cell compositions that can be stored for greater lengths of time before use, i.e., transfusion, and/or that have a reduced amount of storage lesion.Type: ApplicationFiled: August 30, 2013Publication date: August 13, 2015Inventors: Scott Barnum, Rakesh P. Patel, Jordan Welnberg

Publication number: 20150125553Abstract: It has been surprisingly discovered that administration of nitrite to subjects causes a reduction in blood pressure and an increase in blood flow to tissues. The effect is particularly beneficial, for example, to tissues in regions of low oxygen tension. This discovery provides useful treatments to regulate a subject's blood pressure and blood flow, for example, by the administration of nitrite salts. Provided herein are methods of administering a pharmaceutically-acceptable nitrite salt to a subject, for treating, preventing or ameliorating a condition selected from: (a) ischemia-reperfusion injury (e.g., hepatic or cardiac or brain ischemia-reperfusion injury); (b) pulmonary hypertension (e.g., neonatal pulmonary hypertension); or (c) cerebral artery vasospasm.Type: ApplicationFiled: January 5, 2015Publication date: May 7, 2015Applicants: The Government of the United States of America as represented by the Secretary of the Department of, The Board of Supervisors of Louisiana State Univer and Agricultural and Mechanical College, Acting t, The UAB Research Foundation, Loma Linda University, Wake Forest UniversityInventors: Mark T.

Publication number: 20150094772Abstract: Osteosynthesis systems useful in the fusion of cervical vertebrae are described. An osteosynthesis system includes a plate, a set of anchors, a set of locking members, and a set of pins. The plate defines anchor passageways that receive the anchors, locking member passageways that receive the locking member passageways; and pin passageways that receive the pins. Each of the locking member passageways partially intersects one of the anchor passageways and each of the pin passageways provides a passageway extending from a side of the plate to one of the locking member passageways. Each of the locking members is rotatable within the respective one of the locking member passageways and is adapted to engage an adjacent anchor from the side.Type: ApplicationFiled: September 30, 2014Publication date: April 2, 2015Inventors: Craig Black, Willie S.

Publication number: 20140311264Abstract: Anchor towers useful in the alteration of a position of an item connected to an anchor are described. An anchor tower includes an inner sleeve and an outer sleeve disposed over and operably connected to the inner sleeve such that movement of the outer sleeve results in movement of the inner sleeve. A groove is disposed on the inner sleeve and an inwardly-extending projection is disposed on the outer sleeve. Relative movement between the inner and outer sleeves results in movement of the projection within the groove. This movement can produce desired movement of a portion of the inner sleeve, such as a distal arm, based on a structural configuration of the groove.Type: ApplicationFiled: April 20, 2013Publication date: October 23, 2014Inventors: Craig Black, Willie S.
