A system for modulating delivery of a fluid medium includes an injector for injecting the fluid medium during an injection cycle, a delivery catheter including a conduit for delivering the fluid medium, a manifold disposed in a fluid medium flow path between the injector and the delivery catheter, and a pulsatile generator. The pulsatile generator is configured to apply a pulsatile force to the fluid medium defined by a plurality of duty cycles during the injection cycle, each of the duty cycles including a first pressure level and a second pressure level that is lower than the first pressure level.

Adjustable medium diverter

Devices, systems and methods for controlling, regulating, altering, transforming or otherwise modulating the delivery of a substance to a delivery site. The devices, systems and methods optimize the delivery of the substance to an intended site, such as a vessel, vascular bed, organ and/or other corporeal structures, while reducing inadvertent introduction or reflux substance to other vessels, vascular beds, organs, and/or other structures, including systemic introduction.

Devices and methods for modulating medium delivery

An example position determining apparatus, includes a power source, position sensors, and a controller. The position sensors are each selectively powered by the power source and configured to provide a respective sensor reading indicating a proximity of a tracked object. The controller is configured to receive respective sensor readings from the position sensors and identify a position sensor that provided an extremum sensor reading. Based on the sensor readings, the controller selectively cause powering of certain position sensors and prevents powering of other position sensors. The position sensor that provided the extremum sensor reading is one of the powered position sensors. A position output based on the sensor readings is also provided.

Energy-efficient position determining with multiple sensors

An apparatus has a syringe housing and a plunger having a shaft, wherein the plunger is slidably received within the syringe housing between a first and second position. A plurality of Hall sensors are disposed on the shaft. A circuit board is also disposed on the shaft. A battery is disposed on the shaft. A wireless transmitter is disposed on the shaft and provides wireless communication between a Hall sensor and a signal processing device. At least one magnet is fixed proximate the syringe housing.

Volume monitoring systems

A method of determining an amount of medium injected into a patient includes receiving an injection signal from a sensor associated with an injection syringe. A diversion signal is received from a sensor associated with a diversion reservoir. The amount of medium injected is determined based at least in part on the injection signal and the diversion signal.

A system for measurement automation of a fluid injected into a patient includes a reservoir, a fluid injection apparatus, and a measurement automation apparatus. The fluid injection apparatus includes a delivery conduit, an injector for injecting the fluid into the patient, a diverter assembly disposed between the delivery conduit and the injector, and a connector between the diverter assembly and delivery conduit. The diverter assembly is configured to divert at least a portion of the fluid away from an injection fluid path between the injector and the delivery conduit to the reservoir. The measurement automation apparatus includes an injector sensor module, a reservoir sensor module, a processor configured to receive the data from the sensor modules, and a display.

Medium injection diversion and measurement

A system allows for collection and re-use of a fluid medium derived from diverting at least some of the fluid medium of an injection. The system comprises a sterile container, an injector, a delivery catheter, a flow diverter assembly and a diversion reservoir assembly. The delivery catheter is in communication with a selected site within a patient's body. The flow diverter assembly is disposed in a flow path between the injector and the delivery catheter and is configured to divert at least a portion of a medium of the injection from the flow path. The diversion reservoir assembly has a reservoir chamber fluidly coupled to the flow diverter assembly. The reservoir chamber is configured to receive the diverted portion of the fluid medium to allow re-use by the medium injector of the diverted portion.

Reservoir for collection and reuse of diverted medium

Systems and methods for modulating delivery of a fluid medium to a selected site within a patient's body are described. A system 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, a diversion reservoir configured to receive a portion of the fluid medium, and a flow diverter assembly disposed in a fluid medium flow path between the syringe and the delivery catheter. The flow diverter assembly is configured to divert the portion of the fluid medium from the chamber of the syringe away from the delivery of the medium through the delivery catheter conduit during injecting with the syringe. The flow diverter assembly simultaneously increases fluid medium flow resistance with increasing pressure level of the fluid medium passing into the flow diverter assembly.

An apparatus includes a syringe housing and a plunger slidably received within the syringe housing. A plunger magnet is secured to the plunger. A potentiometer housing is fixed to the syringe housing and includes a potentiometer disposed therein. A wiper magnet is also disposed within the potentiometer housing. Movement of the plunger magnet causes a corresponding movement of the wiper magnet.

An apparatus includes a syringe housing and a plunger slidably received within the syringe housing between a first position and a second position. The plunger has a substantially opaque portion and a substantially translucent portion. A light sensor module is disposed on the syringe housing. The light sensor module has a light sensor housing and a first sensor element and a second sensor element. The first sensor element and the second sensor element are disposed within the sensor housing. Positioning the plunger at the first position aligns the substantially translucent portion with the first sensor element and positioning the plunger at the second position aligns the substantially translucent portion with the second sensor element.
