摘要:
An injector for injection a fluid into a patient, including: a first pressurizing mechanism adapted to operatively connect with a first fluid container to pressurize fluid therein; at least a second pressurizing mechanism to operatively connect with a second fluid container to pressurize a fluid therein; a single drive; and a transmission to control how power from the drive is distributed to the first pressurizing mechanism of the first container and to the second pressurizing mechanism of the second container to control injection of fluid from the first container and from the second container. The drive can, for example, be an electric motor or other drive.
摘要:
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.
摘要:
A system for delivering a fluid comprising cells to tissue of a patient includes a container holding an injection fluid and a powered drive. A sensor system provides a measurement indicative of at least shear forces on the cells to a control system. Based at least in part on this measurement, the control system is adapted to transmit a control signal to the powered drive for pressurizing the contents of the container to deposit cells within the tissue of a patient via a fluid path and a patient interface. As an example, the cells can be pregenitor or stem cells.
摘要:
A fluid injection apparatus includes at least one pressurizing mechanism and at least a first fluid container (for example, a syringe or a bulk container) operably associated with the at least one pressurizing mechanism. The first fluid container is adapted to contain a first fluid to be injected. The fluid injection apparatus also includes a controller operably associated with the at least one pressurizing mechanism. The controller includes a programming system to allow programming of an injection protocol including, for example, a plurality of phases. At least one parameter generator is provided to determine parameters of at least one of the plurality of phases of the protocol based at least in part upon a type of the injection procedure.
摘要:
A fluid injection apparatus includes at least one pressurizing mechanism and at least a first fluid container (for example, a syringe or a bulk container) operably associated with the at least one pressurizing mechanism. The first fluid container is adapted to contain a first fluid to be injected. The fluid injection apparatus also includes a pressure modeling system adapted to predict a pressure to be generated at one or more points in the injection fluid path during planned injection procedure based upon variables associated with an injection protocol.
