| 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 |
| 20090240197 | CENTRAL VENOUS CATHETERS AND RELATED EQUIPMENT - Systems, devices, and methods towards improved diagnosis and therapy in connection with central venous catheters (including PICC lines). Included among the many improvements broadly contemplated herein are: arrangements via which a venous catheter can move passively into position in central venous circulation; arrangements via which a catheter can be actively guided without the use of a needle or guide wire; arrangements via which a catheter can be packaged to facilitate easy, rapid, and positionally accurate deployment by medical personnel while maintaining device sterility; and arrangements via which a catheter tip can be imaged during and after insertion. | 09-24-2009 |
| 20090247866 | DATA COMMUNICATION AND CONTROL FOR MEDICAL IMAGING SYSTEMS - A method of coordinating an imaging procedure and an injection procedure, the method comprising the steps of providing an injector system having first and second pressurizing units for pressurizing a contrast medium and a diluent for injection into a patient; providing an imaging system for producing an image of an internal region of the patient from a signal resulting from energy applied to the patient; and providing a data interface interconnecting the injector and imaging systems for enabling exchange of digital information therebetween such that the digital information transmitted between the systems is usable to enable closed loop control of at least one of the injection and the imaging procedures during which the contrast medium and the diluent injected into the patient is adjustable so as to achieve a desired level of enhancement within the internal region of the patient of which the images are acquired during the imaging procedure. | 10-01-2009 |
| 20090326370 | INTERFACE UNIT FOR USE WITH INJECTORS AND IMAGING SYSTEMS AND RELATED DEVICES - A system for producing a contrast-enhanced medical image of a patient includes a source of a contrast or enhancement medium, a pressurizing unit in fluid connection with the source of contrast or enhancement medium, an energy source operable to apply energy to a region of the patient, an imaging unit providing a visual display of an internal view of the patient based upon a signal resulting from the energy applied to the region of the patient, and a control unit. In an embodiment, the signal is affected by a condition of the contrast or enhancement medium in the patient. To control the procedures, the control unit adjusts the condition of the contrast or enhancement medium in the patient based upon the signal. A communication interface preferably enables information between an injector subsystem and an imaging subsystem. | 12-31-2009 |
| 20100063481 | CONNECTOR SYSTEM HAVING A COMPRESSIBLE SEALING ELEMENT AND A FLARED FLUID PATH ELEMENT TO REDUCE FLUID FLOW RESTRICTIONS - 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. Another system for connecting to a fluid path section includes a connector including a connection mechanism to connect the connector to the fluid path section and a passage therethrough. The passage is in fluid connection with a first fluid path element downstream of the connector. The first fluid path element includes a lumen therethrough. The diameter of the lumen is flared outward to a larger diameter at a proximal end of the fluid path element. The proximal end of the first fluid path element can abut a surface of the connector in which the distal end of the fluid path is formed. The inner diameter of the proximal end is greater than the diameter of the passage of the second cooperating connector. The outer diameter of the proximal end of the first fluid path element can also be flared outward | 03-11-2010 |
| 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 |
| 20100237545 | METHOD OF MANUFACTURING SYRINGES AND OTHER DEVICES - A syringe for use in a pressurized injection of a fluid includes a syringe barrel including a polymeric material having undergone expansion via blow molding. An inner diameter of the syringe barrel can, for example, be sufficiently constant (over at least a portion of the axial length of the syringe) that a plunger slidably positioned within the syringe barrel and in generally sealing contact with an inner wall of the syringe barrel can be used within the syringe barrel to generate a pressure of at least 1 psi within the syringe barrel. In several embodiment, the inner diameter of the syringe barrel is sufficiently constant to generate a pressure of at least 100 psi, at least 300 psi, or even at least 500 psi within the syringe barrel. A method of forming a syringe includes the steps of: injection molding at least one polymeric material to form a preform; placing the preform into an blow mold die; and expanding at least a portion of the preform while heating the preform within the die to form a barrel of the syringe. The syringes can be formed to withstand relatively high pressures as described above. The at least one polymeric material can, for example, be polyethyleneterephthalate, cyclic olefin polymer, polypropylene, polystyrene, polyvinylidene chloride, polyethylene napthalate and/or nylon. | 09-23-2010 |
