The first and/or second polymers provide the respective regions with one or more properties including swellability in the presence of water, active agent content, permeability to the diffusion of active agent from or through the layer, moisture vapor permeability, and adhesion to tissue.Type: ApplicationFiled: July 30, 2010Publication date: September 6, 2012Inventors: Stanley Harpstead, Loren L. Barber, JR.

Patent number: 8257732Abstract: A device for promoting the clotting of blood comprises a clay material in particle form and a receptacle for containing the clay material. At least a portion of the receptacle is defined by a mesh. Another device comprises a gauze substrate and a clay material disposed on the gauze substrate. Another device is a bandage comprising a substrate, a mesh mounted on the substrate, and particles of a clay material retained in the mesh. A hemostatic sponge comprises a substrate, a hemostatic material disposed on a first surface of the substrate, and a release agent disposed on a second surface of the substrate. The release agent is disposed on the wound-contacting surface of the substrate. When treating a bleeding wound, application of the hemostatic sponge causes at least a portion of the hemostatic material to come into contact with blood through the release agent and through the substrate.Type: GrantFiled: May 25, 2011Date of Patent: September 4, 2012Assignee: Z-Medica CorporationInventors: Raymond J. Huey, Denny Lo, Daniel J. Burns, Giacomo Basadonna, Francis X. Hursey

Patent number: 8252344Abstract: A composition for promoting the formation of clots in blood comprises a zeolite and a binder. The zeolite is adjusted to have a specific moisture content. Processes by which the moisture content is adjusted include drying, re-hydrating, and combinations of drying and re-hydrating. A method of forming the composition comprises the steps of providing a zeolite and adjusting the moisture content such that upon application of the composition to a wound, a heat of hydration is reduced and heat transferred to the wound is reduced. A method of clotting blood flowing from a wound comprises the steps of applying the zeolite to the wound and maintaining the zeolite in contact with the wound for a predetermined amount of time, the zeolite having an adjusted moisture content and being capable of producing a controllable exothermic effect on the wound.Type: GrantFiled: September 13, 2004Date of Patent: August 28, 2012Assignee: Z-Medica CorporationInventor: Francis X. Hursey

Patent number: 8252970Abstract: Devices and methods are disclosed for achieving hemostasis in traumatized patients. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery or military setting. In such cases, the patient may have received trauma to abdominal viscera, the thoracic cavity or the periphery. The devices utilize fluid impermeable outer surfaces and distributed pressure to achieve tamponade and hemostasis, primarily by exertion of pressure. The devices are flexible, bendable, and conformable in their wet or dry state so that they exert distributed pressure on the wound. Peripheral haemostatic packing devices include optional adhesive structures to attach one packing device to another. The hemostatic packing devices may be placed and removed by open surgery or laparoscopic access without generating excessive re-bleeding. The devices can be inserted into a wound and filled with fluid, gel, or particulates through an axially elongate tube to generate pressure to tamponade the wound.Type: GrantFiled: May 17, 2011Date of Patent: August 28, 2012Assignee: Damage Control Surgical Technologies, Inc.Inventors: Robert F. Buckman, Jay A. Lenker, Donald J. Kolehmainen

Patent number: 8237007Abstract: Wound dressings and methods of manufacturing wound dressings are provided. The wound dressings include portions that are converted from a moisture vapor permeable material to a material having reduced moisture vapor permeability. The conversion may be accomplished in a variety of ways. In some embodiments, a solvent is used to dissolve a porous material to thereby form a non-porous film. In other embodiments, heat is applied to melt a porous material to thereby form a non-porous film. The heat may be applied using a heated gas or a heating element to directly or indirectly heat the material.Type: GrantFiled: January 10, 2008Date of Patent: August 7, 2012Assignee: PolyRemedy, Inc.Inventor: Oleg Siniaguine

Patent number: 8234842Abstract: A multi-layered wound dressing includes a moisture-retaining portion for enhancing the healing of a wound. The wound dressing includes an intermediate layer that has both water soluble and water insoluble fibers. An apparatus that includes a cutting tool and a reservoir of liquid to pre-moisten a portion of the dressing may be used to manufacture the dressings.Type: GrantFiled: August 26, 2008Date of Patent: August 7, 2012Assignee: PolyRemedy, Inc.Inventor: Oleg Siniaguine

Patent number: 8237010Abstract: A therapeutic device for promoting the healing of a wound in a mammal is disclosed. An exemplary device comprises a permeable structure having a plurality of depressions formed in a surface thereof. In use, the surface having the depressions is disposed adjacent a surface of the wound. A method of manufacturing a therapeutic device for promoting the healing of a wound in a mammal comprising the steps of providing a permeable substrate, and forming a plurality of depressions into a surface of the permeable substrate to provide the therapeutic device. A method of treating a wound comprises: providing a permeable structure comprising a plurality of randomly disposed fibers and having i) a plurality of wound surface contact elements disposed between end portions of the structure, and ii) a plurality of voids defined by the contact elements; and applying the permeable structure to at least one surface of the wound.Type: GrantFiled: August 30, 2011Date of Patent: August 7, 2012Assignee: Boehringer Technologies, L.P.Inventors: John R. Boehringer, John Karpowicz, Christopher L. Radl
