  • Publication number: 20130126559
    Abstract: A displacement syringe having a housing with a distal tip and a proximal end; a moveable outer plunger within the housing having an elongated passageway; at least one moveable inner plunger within the passageway of the outer plunger; at least one first seal between the outer plunger and the housing; and at least one second seal between the inner plunger and the outer plunger is disclosed herein. The syringe may have a lock at the proximal end of the housing and/or a valve at the distal tip of the housing. The syringe may also have a plurality of inner plungers of various diameters. A transfer system and delivery system are also disclosed herein. Methods to accurately and efficiently deliver small volumes using the displacement syringe are also disclosed.

  • Patent number: 8182444
    Abstract: 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.

  • Publication number: 20100063481
    Abstract: A system for connecting a conduit to a fluid path element, includes a length of conduit, a compressible sealing element positioned on a distal end of the length of conduit to be attached to the fluid path element, a first cooperating connector positioned around the length of conduit proximal to the sealing element and a second cooperating connector. The first cooperating connector includes a first cooperating connection mechanism and the second cooperating connector includes a second cooperating connection mechanism. The first cooperating connection mechanism and the second cooperating connection mechanism are adapted to form a connection between the first cooperating connector and the second cooperating connector. The connection causes the compression of the sealing element. The second cooperating connector further includes a passage therein in fluid connection with a connection for the fluid path element.

  • Publication number: 20080294096
    Abstract: 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.
