Abstract: An implantable heart assist system includes a compressible pumping chamber including an inlet conduit to be placed in fluid connection with the descending thoracic aorta and an outlet conduit to be placed in fluid connection with the thoracic aorta; and a pump system comprising a first rigid member, a second rigid member positioned so that at least a portion of the pumping chamber may be positioned between the first and second rigid members, a drive system configured to cause the second rigid member to move toward or away from the first rigid member, and a controller in operative connection with the drive system and controlling the drive system, wherein movement of the second rigid member toward the first rigid member results in compresses the pumping chamber and movement of the second rigid member away from the first rigid member expands the pumping chamber.

Abstract: Embodiments are disclosed in which a process receives, via a graphical user interface (GUI) of a spreadsheet application, a function call. The function call includes a source string attribute identifying a string and a search string attribute identifying a substring to be identified in the string. The process performs a function associated with the function call by searching for the substring in the string and subsequently returning a subset of the string proximate to a location of the substring in the string.

Abstract: An implantable heart assist system includes a compressible pumping chamber including an inlet conduit configured to be placed in fluid connection with the descending thoracic aorta and an outlet conduit configured to be placed in fluid connection with the thoracic aorta; and a pump system comprising a first rigid member, a second rigid member spaced from the first rigid member so that at least a portion of the pumping chamber may be positioned between the first rigid member and the second rigid member, a drive system configured to cause the second rigid member to move toward the first rigid member or away from the first rigid member, and a controller in operative connection with the drive system and controlling the motor, wherein movement of the second rigid member toward the first rigid member results in compression of the pumping chamber and movement of the second rigid member away from the first rigid member causes expansion of the pumping chamber.

Abstract: An implantable heart assist system, includes a pumping chamber formed of a flexible material and being adapted to be placed in fluid connection with the aorta and a pump system comprising a first rigid member and a spaced apart second rigid member so that at least a portion of the pumping chamber may be positioned therebetween, a drive system comprising a motor. The motor is adapted to cause the second rigid member to move toward the first rigid member to compress the pumping chamber or away from the first rigid member to expand the pumping chamber. A controller is in operative connection with the drive system and controlling the motor.

Abstract: A system includes an implantable pump system for assisting blood flow in a patient including at least one movable valve. The movable valve is in a normally open state when the moveable valve is not being powered and a drive system in operative connection with the moveable valve to move the moveable valve under power. The system further includes an energy transfer system to provide energy to the drive system. The energy transfer system includes an external system including a power source and an external coil and an internal system including an internal coil adapted to receive transcutaneous energy transmitted from the external coil. The internal system has at least a first state wherein energy transmission from the external coil is required to provide operational power to the drive system.

The motor is adapted to rotate either the extending member or the nut relative to the other to convert rotary motion of the motor to linear motion to cause the second rigid member to move toward the first rigid member or away from the first rigid member. The heart assist system further includes a controller or a control system in operative connection with the drive system and controlling the motor.

Abstract: The fluid injector system includes a source of injection fluid, a pump device, and a fluid path set in fluid connection with the source of injection fluid and the pump device. The fluid path set includes a drip chamber including an elongated body having a raised projection from substantially a top end to substantially a bottom end, the elongated body configured to receive and contain the injection fluid. A fluid level sensing mechanism is operably associated with a fluid control device, and includes a support for the drip chamber body, wherein the support is adapted such that the raised projection is in operational contact with a fluid level sensor associated with the support. The fluid level sensing mechanism is operable to transmit ultrasonic or light energy through the raised projection to be sensed by the fluid level sensor for sensing the injection fluid level in the drip chamber.
