| 20080294096 | Delivery of Agents Such as Cells to Tissue - A system for delivering a fluid comprising cells to tissue of a patient, includes: a least a first container for holding an injection fluid in which the agent is carried; a first powered drive in operative connection with the container, the first powered drive being operable to pressurize contents of the container; a control system in operative connection with the first powered drive and operative to control the first powered drive; a fluid path in fluid connection with the container, the fluid path including a patient interface adapted to deposit the cells within tissue of the patient; a sensor system; and a communication system in connection with at least the control system and the sensor system. The communication system is adapted to provide information to the control system. The control system in adapted to transmit a control signal to at least the first powered drive based at least in part on information provided to the control system. The cells can for example be pregenitor cells or stem cells. | 11-27-2008 |
| 20090012497 | SYSTEMS AND METHODS OF DELIVERING A DILATED SLURRY TO A PATIENT - A system for delivering a slurry to a patient includes a fluid, a material that is non-dissolvable or immiscible in the fluid, thereby forming a slurry, a container adapted to contain the slurry and a supernate of the slurry, the container defining an outlet through which the slurry is delivered to the patient, a fluidizing system associated with the container, a pressurizing mechanism adapted to create a pressure to cause the slurry contained within the container to flow for delivery to the patient and a control unit in communication with and adapted to control the fluidizing system and the pressurizing mechanism. The fluidizing system is adapted to effect dilation of the slurry while maintaining at least a portion of the supernate. | 01-08-2009 |
| 20090112164 | SYSTEM AND METHOD FOR PROPORTIONAL MIXING AND CONTINUOUS DELIVERY OF FLUIDS - A system and method for mixing and delivering fluids such as contrast media and saline is disclosed including at least two fluid sources, a pump, a joining fluid path connecting the at least two fluid sources to an inlet to the pump, and a valve device in the fluid path upstream of the pump. The valve device includes an actuator adapted to restrict flow in at least one of respective fluid lines connecting the at least two fluid sources to the pump inlet. A patient interface device may be associated with an outlet of the pump. The valve device actuator is generally adapted to restrict the flow in at least one of the respective fluid lines such that an incremental positional change in valve device actuator position provides a substantially linear change in fluid mixture ratio of the fluids from the at least two fluid sources to the pump inlet. | 04-30-2009 |
| 20100174183 | MULTIPLE LUMEN DIFFUSION CATHETER - A method and device for the simultaneous or sequential introduction of multiple fluids into the bloodstream including a multiple lumen catheter with corresponding multiple hole sets. By introducing a second fluid such as saline, the concentration and bolus of a first fluid, such as a contrast agent, can be controlled and optimized. | 07-08-2010 |
| 20100185040 | FLUID DELIVERY SYSTEMS, DEVICES AND METHODS FOR DELIVERY OF HAZARDOUS FLUIDS - A system for injecting a patient, includes a container enclosing a hazardous pharmaceutical; a first pump to deliver a hazardous pharmaceutical to a patient and a fluid path operably connected to the first pump, the container, and the patient. The system further includes a hazardous material containment suitable to confine the hazardous pharmaceutical during connection of the hazardous pharmaceutical container to the fluid path. | 07-22-2010 |
| 20100298699 | System and Method for Proportional Mixing and Continuous Delivery of Fluids - A system and method for mixing and delivering fluids such as contrast media and saline is disclosed including at least two fluid sources, a pump, a joining fluid path connecting the at least two fluid sources to an inlet to the pump, and a valve device in the fluid path upstream of the pump. The valve device includes an actuator adapted to restrict flow in at least one of respective fluid lines connecting the at least two fluid sources to the pump inlet. A patient interface device may be associated with an outlet of the pump. The valve device actuator is generally adapted to restrict the flow in at least one of the respective fluid lines such that a positional change in valve device actuator position provides a change in fluid mixture ratio of the fluids from the at least two fluid sources to the pump inlet. | 11-25-2010 |
| 20110049866 | FLUID PATH CONNECTORS AND CONTAINER SPIKES FOR FLUID DELIVERY - A fluid connector includes an extending section including a spiked end to pierce the container port. The extending section includes at least one air conduit and at least one fluid conduit therethrough. The extending section further includes a first abutment member and second abutment member. The first abutment member is adapted to abut a first or air side of the container port upon piercing of the container port. The second abutment member is spaced from the first abutment member and is adapted to abut a second or fluid sided of the container port. The fluid connector can further include grasping members extending from the extending section to facilitate rotation of the extending section relative to the container port during piercing thereof. The fluid connector can also include a check valve in fluid connection with the air line. In several embodiments, the check valve is positioned within the extending section. | 03-03-2011 |
| 20110152681 | PUMPING DEVICES, SYSTEMS AND METHODS FOR USE WITH MEDICAL FLUIDS INCLUDING COMPENSATION FOR VARIATIONS IN PRESSURE OR FLOW RATE - A system for delivery of a medical fluid to a patient includes a pump system including a pressurizing unit to pressurize the medical fluid and a drive system in operative connection with the pressurizing unit. The pump system exhibits variation in pressure during operation. The system further includes a compensating system in fluid connection with the medical fluid pressurized by the pressurizing unit. The compensating system defines a displacement volume in fluid connection with the pressurized medical fluid that is altered in a predetermined manner to alter the variation in pressure. The compensating system can, for example, reduce pulsatility of pressure during flow. | 06-23-2011 |
