US Patent:

20200297367, Sep 24, 2020

Filed:

May 13, 2020

Appl. No.:

15/929630

Inventors:

- Mansfield MA, US
Dinh Nguyen - Garden Grove CA, US
Hoai Nguyen - Westminster CA, US

International Classification:

A61B 17/22
A61F 2/95
A61B 17/221

Abstract:

Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the removal device. The removal device can have a core assembly that includes a hypotube coupled to a first electrical terminal and a pushwire coupled to a second electrical terminal, the pushwire extending through the hypotube lumen. An insulating layer separates the hypotube and the pushwire, and an interventional element is coupled to a distal end of the pushwire. The interventional element can be disposed adjacent to a thrombus. An electrical signal is delivered to the interventional element to promote adhesion of the thrombus to the interventional element. The electrical signal can optionally be a periodic waveform, and the total energy delivered can be between 0.75-24,000 mJ and the peak current delivered via the electrical signal can be between 0.5-5 mA.

Inventors:

- Houston TX, US
Dinh Nguyen - Houston TX, US

International Classification:

F01P 3/20
F01N 5/02
F17C 7/04

Abstract:

Apparatus and methods for vaporizing liquid nitrogen at sufficient pressure, temperature, and volume to enable a single mobile pumper to meet the needs of many industrial applications. The dual-mode nitrogen pumper of the present invention utilizes a reciprocating pump and heat from the engine coolant and exhaust stream of an internal combustion engine, as well as heat from hydraulic fluid used to load the engine, and transfers that heat to liquid nitrogen pumped through a first heat exchanger and a second, internally-fired heat exchanger is provided to transfer heat to liquid nitrogen pumped through a second heat exchanger. The temperature of the hydraulic fluid is maintained, and the temperature, pressure, and flow rate of the vaporized nitrogen is controlled, by balancing the engine load against the nitrogen pumping rate.

International Classification:

F24H 9/00

US Classification:

122 311

Abstract:

Apparatus and methods for vaporizing LNG while producing sufficient volume of compressed natural gas at sufficient pressure to meet the needs of internal combustion engines, gas turbines, or other high consumption devices operating on natural gas or on a mixture of diesel and natural gas. The LNG vaporizer of the present invention incorporates a reciprocating pump to provide vaporized LNG to an output at rates and pressures as required by the particular application. The heat rejected into the engine coolant and the exhaust stream from an artificially loaded internal combustion engine, as well as the hydraulic heat resulting from artificially loading the engine, is transferred to the LNG as the LNG passes through a heat exchanger. Exhaust heat is transferred to the engine coolant after the coolant passes through the heat exchanger.
