Abstract: An intravascular ultrasound (IVUS) catheter-based device for targeted delivery of ultrasound-activated emulsions of oxygen-scavenging droplets into a bloodstream of patients suffering from a hypoxic condition and methods utilizing the device to protect the patients from reperfusion injury upon restoration of oxygenated blood to a hypoxic tissue.

Abstract: A pumping system for blood for a patient includes a sensorless pump having no sensors disposed in the pump itself for moving the blood, a motor and a blood transport port through which blood is received from the patient and is pumped into the patient. The system also includes a controller connected to the pump for controlling the pump so a desired flow rate of blood can be maintained by the pump.

Abstract: A blood pump device comprises a blood pump having blood transport ports, cannulae connected to the ports, and a coating material covering the junction between the inner surfaces of the ports and cannulae. This forms a smooth transition so blood can flow unimpeded therefrom and collection cavities for the blood are eliminated. Also included is a method for producing a smooth coating. The blood pump device comprises a second portion including a stator mechanism, a rotor mechanism, an impeller, a journal, and a seat member. The second portion is constructed to pump blood through the cannulae when power is provided. The blood pump device is also equipped with a safety occluder device, a sensor for detecting back emf in the stator mechanism, and a controller having the capability of indicating stator current and rotor speed.

Abstract: A blood pump device which includes a blood pump having blood transport ports and cannulae connected to the ports. The blood pump device also includes a coating material covering the junction between the inner surfaces of the ports and cannulae. A method of producing a smooth coating. A blood pump device including a second portion having a stator mechanism and a rotor mechanism disposed adjacent to and driven by the stator mechanism. The second portion has a journal disposed about the rotor mechanism to provide support therewith. The second portion has an impeller disposed in the chamber and a seal member for sealing about a shaft of the impeller. The seal member is fixedly attached to the journal so that the seal member is supported by the journal. A mechanism for providing power to the blood pump so that blood can be pumped through a cannula.

The blood pump device also comprises a coating material covering the junction between the inner surfaces of the ports and cannulae. This forms a smooth transition so blood can flow unimpeded therefrom and collection cavities for the blood are eliminated. The invention is also related to a method of producing a smooth coating. The present invention is a blood pump device comprising a second portion having a stator mechanism and a rotor mechanism disposed adjacent to and driven by the stator mechanism. The second portion has a journal disposed about the rotor mechanism to provide support therewith. The second portion has an impeller disposed in the chamber and a one-piece seal member for sealing about a shaft of the impeller. The seal member is fixedly attached to the journal so that the seal member is supported by the journal.

Abstract: A tether system for an animal. The tether system has an apparatus which is electrically or fluidically powered or monitored with greater than 200 milliamps of current. The tether system is also comprised of an area for the animal and a structure above the area. The tether system is comprised of an anchor for attachment to the structure. The tether system is also comprised of a mechanism for providing power to the apparatus to operate it. The providing mechanism is in electrical communication with the anchor and the apparatus. The anchor prevents entanglement of the power providing means or mechanism as the animal moves freely about the area. Preferably, the tether system also includes a mechanism for providing fluid to or from the animal. The fluid providing mechanism is fluidically connected to the anchor and the patient. Additionally, the tether system can include a mechanism for transmitting electrical signals from the animal.
