Patent number: 8927459Abstract: A method is provided for inhibiting plant growth by inducing hypothermia by applying a treating substance to summer annual weeds and grasses. Susceptible undesirable plants will be killed by this treatment, while non-susceptible desirable plants will not be adversely affected by this treatment. Compressed carbon dioxide may be applied to other summer grasses to cause the grasses to become dormant. An apparatus is provided for inducing hypothermia in undesirable plants by applying a treating substance. A canister capable of housing gas may be provided. A valve may be provided to control the amount and pressure of gas dispensed from the canister.Type: GrantFiled: March 8, 2013Date of Patent: January 6, 2015Assignee: Arctic, Inc.Inventors: Robby James Howerton, Gina Marie Stewart, Steven Lee Worm

Patent number: 8916339Abstract: A composition of neural tissue is made of spinal cord tissue harvested from a spinal cord of a mammal. The spinal cord tissue is harvested from vertebral column of the mammal. The spinal cord tissue is harvested post mortem. The mammal is one of a primate, an equine, a bovine, a porcine or other mammalian animal. The spinal cord tissue is dried or has the water content in the tissue reduced or eliminated by freeze drying or hypothermic dehydration.Type: GrantFiled: March 7, 2014Date of Patent: December 23, 2014Assignee: Vivex Biomedical, Inc.Inventor: Theodore I. Malinin

Publication number: 20140356850Abstract: Systems and methods of the invention generally relate to prolonging viability of bodily tissue in static cold storage and hypothermic machine perfusion techniques by reducing the rate of edema through the application of compressive force to the bodily tissue via a compression device. Compression devices of the invention may comprise biocompatible materials and may apply compressive force through incorporation of elastic materials, through expandable bladders, or other means. Certain embodiments include perfusion devices comprising a pneumatic system, a pumping chamber, and an organ chamber. The pumping chamber is configured to diffuse a gas into a perfusate and to generate a pulse wave for moving the perfusate through a bodily tissue. The organ chamber is configured to receive the perfusate along with a bodily tissue fitted with a compression device. Both the organ chamber and the pumping chamber are configured to substantially automatically purge excess fluid.Type: ApplicationFiled: August 15, 2014Publication date: December 4, 2014Inventors: Lisa Maria Anderson, Jared Alden Judson
