Patent number: 8020694Abstract: A transport unit includes a plurality of permanent magnets arranged to provide a magnetic holding field for protecting hyperpolarized gas during storage and/or transport. The permanent magnets are configured in a relatively light weight manner to project a substantially cylindrical magnetic holding field or spherical holding field in space. The magnet arrangements can include primary magnets and field shaping secondary magnets which act to enlarge the region of homogeneity. The permanent magnet arrangement can also be provided with a cylindrical shaped flex sheet magnetically activated to provide the magnetic holding field. The permanent magnet arrangements do not require disassembly to insert or remove one or more containers of hyperpolarized gas in or out of the transport unit.Type: GrantFiled: January 19, 2006Date of Patent: September 20, 2011Assignee: Medi-Physics, Inc.Inventors: Kenton C.

Patent number: 6995641Abstract: A compact portable transport unit for shipping hyperpolarized noble gases and shielding same from electromagnetic interference and/or external magnetic fields includes a means for shifting the resonance frequency of the hyperpolarized gas outside the bandwidth of typical frequencies associated with prevalent time-dependent fields produced by electrical sources. Preferably the transport unit includes a magnetic holding field which is generated from a solenoid in the transport unit. The solenoid includes a plurality of coil segments and is sized and configured to receive the gas chamber of a container. The gas container is configured with a valve, a spherical body, and an extending capillary stem between the valve and the body. The gas container or hyperpolarized product container can also be formed as a resilient bag.Type: GrantFiled: March 28, 2003Date of Patent: February 7, 2006Assignee: Medi-Physics, Inc.Inventors: Kenton C.

Patent number: 6523356Abstract: Methods of dispensing meted quantities of hyperpolarized gas to form a hyperpolarized gas mixture include pre-filling a gas syringe with a quantity of non-polarized gas, then introducing the hyperpolarized gas therein while the non-polarized gas is held therein, and expelling both the hyperpolarized gas and non-polarized gas from the syringe. Methods of inhibiting the presence of oxygen in gas flow paths and extraction systems are also described.Type: GrantFiled: September 7, 2001Date of Patent: February 25, 2003Assignee: Medi-Physics, Inc.Inventors: Kenton C.

Patent number: 6286319Abstract: Methods of extracting and removing hyperpolarized gas from a container include introducing an extraction fluid into the container to force the hyperpolarized gas out of an exit port. The hyperpolarized gas is forced out of the container separate and apart from the extraction fluid. Alternatively, if the fluid is a gas, a portion of the gas is mixed with the hyperpolarized gas to form a sterile mixed fluid product suitable for introduction to a patient. An additional method includes engaging a gas transfer source such as a syringe to a transport container and pulling a quantity of the hyperpolarized gas out of the container in a controlled manner. Alternatively, one or more gas syringes can be employed to mete out predictable quantities of hyperpolarized gas or gas mixtures including quantities of buffer gases.Type: GrantFiled: March 20, 2000Date of Patent: September 11, 2001Assignee: Medi-Physics, Inc.Inventors: Kenton C.

An additional method includes engaging a gas transfer source such as a syringe to a transport container and pulling a quantity of the hyperpolarized gas out of the container in a controlled manner. Another method includes introducing a quantity of liquid into a container and covering at least one predetermined internal surface or component with the liquid to mask the surfaces and keep the hyperpolarized gas away from the predetermined internal surface, thereby inhibiting any depolarizing affect from same.Type: GrantFiled: September 30, 1998Date of Patent: May 29, 2001Assignee: Medi-Physics, Inc.Inventors: David L.
