Patent number: 8343537Abstract: A hemostatic device for promoting the dotting of blood includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood emanating from the wound to cause the clotting. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. A hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.Type: GrantFiled: January 31, 2012Date of Patent: January 1, 2013Assignee: Z-Medica, LLCInventors: Raymond J.

Publication number: 20090162406Abstract: A method for decreasing the time it takes for a wound to heal includes applying hemostatic agent to the wound, inflaming tissue surrounding the wound to facilitate the deposition of fibroblast, thereby accelerating the subsequent contraction of the wound and the onset of the proliferative healing stage, and causing the re-epithelization of the tissue at a faster rate than if no hemostatic agent was applied. A method for promoting the healing of a bleeding wound includes coating a hemostatic agent onto a substrate, applying the substrate to the bleeding wound so that an effective amount of the hemostatic agent is applied to the wound, inflaming the tissue, and causing the re-epithelization of the tissue at a faster rate than if no hemostatic agent was applied. In at least some methods, a clotting cascade and platelet aggregation within the bleeding wound is accelerated, and blood loss from the wound is decreased.Type: ApplicationFiled: September 4, 2008Publication date: June 25, 2009Applicant: Z-MEDICA CORPORATIONInventors: Giacomo Basadonna, Raymond J.

Publication number: 20080317831Abstract: A device for promoting the clotting of blood includes a web of non-woven fibers of a polymer having a hemostatic agent disposed on the fibers. The fibers are randomly arranged to form the web. When the device is applied to a bleeding wound, at least a portion of the hemostatic agent comes into contact with blood to cause the blood to clot. A hemostatic sponge includes a melt-blown non-woven fibrous web of polymer material and a hemostatic agent that is attached to the fibers. A method of making a hemostatic sponge includes the steps of melting a polymer and combining the polymer with a hot air stream. A hemostatic agent is added to the melt. The melt with the hemostatic agent is then drawn into fibers and collected as a web.Type: ApplicationFiled: June 17, 2008Publication date: December 25, 2008Inventor: Denny Lo

A system for radiographically imaging an internally bleeding wound includes means for delivering a radioopaque blood clotting agent and means for radiographically imaging the radioopaque blood clotting agent. A method of imaging an internally bleeding wound includes the steps of inserting a catheter into a patient; advancing the catheter to a point adjacent the bleeding wound; depositing a radioopaque zeolite at the bleeding wound; and imaging the radioopaque zeolite to monitor blood-clotting caused by the zeolite.Type: ApplicationFiled: February 22, 2007Publication date: August 28, 2008Inventors: Denny Lo, Giacomo Basadonna

Additional components may also be included. The first component may be a zeolite and the second component may be clay. A device for promoting the clotting of blood comprises a receptacle for retaining particles of a hemostatic agent therein, at least a portion of the receptacle being defined by a mesh. A pad for controlling bleeding comprises a mesh structure defined by openings sized to accommodate the flow of blood therethrough and also by a hemostatic agent retained in the mesh structure. A bandage applicable to a bleeding wound comprises a substrate, a mesh mounted on the substrate, and a hemostatic agent retained in the mesh.
