A ramp is formed in communication with the side exit port and the ramp has a preselected slope that controls the angle at which the marker is ejected. The marker is ejected from the side exit port into tissue when the spring unloads abruptly as the marker clears the crimp. | 05-12-2016 |
20160136413 | CONTROLLING FLOW IN A MEDICAL INJECTION SYSTEM - A valve apparatus for a medical injection system includes a pinching member and at least one spring-loaded anvil. A tubing line of the injection system may be positioned between the pinching member and the anvil, such that when the pinching member is moved into a pinching position adjacent to the anvil, for example, by rotation of a shaft to which the member is coupled, the pinching member compresses the tubing line against the spring-loaded anvil. The pinching member is preferably rotatable about an auxiliary axis, which is eccentric, or offset from a central axis of the shaft. A spring member of the spring-loaded anvil is preferably pre-loaded. In certain applications, the pinching member, when moved into the pinching position, applies a pinching force of greater than approximately 45 pounds, for example, to prevent flow through the tubing line at an injection pressure of up to approximately 1200 psi. | 05-19-2016 |

20160158434 | POWER INJECTOR WITH DECAY CONSTANT FUNCTIONALITY - A power injector is disclosed having power injector control logic, which in turn includes a decay constant cross-reference, for instance in the form of a data structure. Flow rate decay constant information may be stored by the decay constant cross-reference. A decay constant, which may be used by the power injector to generate an exponentially decaying flow rate for an injection, may be stored in the decay constant cross-reference in conjunction with a particular imaging unit. The decay constant cross-reference may be searched by entering a model or module number of an imaging unit to identify the corresponding flow rate decay constant to be used by the power injector. | 06-09-2016 |

20160184506 | INJECTOR WITH PIEZO MOTOR SYSTEM WITH WAVE FORM TUNING - A piezo motor (150) may be tuned to a specific frequency range having a small deviation from an operational frequency range of a magnetic resonance imaging system component. This may be done by applying a pressure to the piezo motor (150), generating at least one signal via a control board (200) and where this signal is at a selected frequency within the specific frequency range applying the signals to the piezo motor (150), measuring a vibration frequency of the piezo motor (150), and varying the applied pressure to the piezo motor (150). The applied pressure may continue to be adjusted until the measured vibration frequency of the piezo motor (150) is at a resonant frequency for the piezo motor (150). After the piezo motor (150) is tuned in this manner, the piezo motor (150) may be incorporated into a magnetic resonance imaging system component. | 06-30-2016 |
