摘要： A system for modulating delivery of a fluid medium to a selected site within a patient's body includes a syringe for injecting the fluid medium, a delivery catheter including a conduit for delivering the fluid medium from outside of the body to the selected site within the body, and a flow diverter assembly disposed in a fluid medium flow path between the syringe and the delivery catheter. The syringe includes a chamber for receiving the fluid medium therein. The flow diverter assembly is configured to simultaneously divert at least some of the fluid medium within the chamber of the syringe away from the delivery of the medium through the delivery catheter conduit during injecting with the syringe, and wherein the flow diverter assembly creates increasing medium fluid flow resistance with increasing pressure level of the fluid medium within the flow diverter assembly. A method for modulating fluid delivery to a selected site within a patient's body is also disclosed.

摘要： Apparatus administers dental anesthetic to intraligamentary tissue with a drive unit and handpiece with injection needle connected by flexible tube to the unit. The drug is passes to the tissue at an instantaneous pressure at the needle tip that varies due to placement. A minimum threshold pressure is desired for administering the drug to the tissue. A practitioner moves the handpiece to insert the needle tip near the intraligamentary tissue and the instantaneous pressure is sensing or calculating. An auditory ascending signal indicates when the instantaneous pressure is rising, and when the instantaneous pressure reaches the threshold pressure a perceptible auditory specific signal indicates the practitioner has moved the tip into intraligamentary tissue. The tip is then maintained for supplying a selected dosage of the drug. Another auditory signal notifies the practitioner that the instantaneous pressure is declining or fluctuating before reaching the minimum threshold pressure.

摘要： A manually operated hydraulic syringe includes a syringe barrel having an interior surface. The interior surface bounds a first chamber having a first transverse cross-sectional area and a second chamber having a second transverse cross-sectional area. The first chamber is in fluid communication with the second chamber and the transverse cross-sectional area thereof is smaller than the transverse cross-sectional area of the second chamber. A first plunger has a distal end slidably disposed within the first chamber. A second plunger is slidably enclosed within the second chamber. Sealed in substantial isolation within the syringe barrel between the first and second plungers is a hydraulic fluid, such as water or oil. Rotatably coupled to the distal end of the syringe body is a nozzle or cartridge in which a dispensing material, such as a high viscosity fluid, can be selectively disposed. Manual advancement of the first plunger within the first chamber results in advancement of the second plunger within the second chamber under an increased force. Advancement of the second plunger within the syringe body functions to dispense the dispensing material from the attached nozzle or cartridge.

摘要： An apparatus for injectate delivery includes a cartridge, a linear actuator, a rotary motor mechanically coupled the actuator, and a controller coupled to the motor. The controller controls a linear motion of the actuator by controlling an electrical input supplied to the motor in a first interval during which the motor is stationary with the linear actuator engaged with the cartridge to displace an injectate in the cartridge, a second interval following the first interval during which the controller accelerates the motor from stationary to a first speed selected to create a jet of the injectate from the cartridge with a velocity sufficient to pierce human tissue to a subcutaneous depth, a third interval during which the controller maintains the motor at or above the first speed, and a fourth interval during which the controller decelerates the motor to a second speed to deliver the injectate at the subcutaneous depth.
