An engagement mechanism associated with a reciprocally movable piston of a fluid injector is configured for releasably engaging an engagement portion at a proximal end of a rolling diaphragm syringe having a flexible sidewall configured for rolling upon itself when acted upon by the piston. The engagement mechanism has a plurality of engagement elements reversibly and pivotally movable about a pivot pin relative to the engagement portion of the syringe between a first position, where the plurality of engagement elements are disengaged from the engagement portion of the syringe, and a second position, where the plurality of engagement elements are pivotally movable about the pivot pin in a radially inward direction to engage with the engagement portion of the syringe. The engagement mechanism further has a drive mechanism for moving the plurality of engagement elements between the first position and the second position.

An MRI system (100) is proposed (for generating one or more images of a body-part of a patient under analysis); the MRI system (100) comprises an injector head assembly (155), for injecting at least one medical fluid into the patient, having a clock unit (340) for providing a clock signal with a clock frequency. The MRI system (100) comprises means (420-425; 445-460) for adjusting the clock frequency in response to a manual command and/or to a detection of a degradation of the images. An injector system (155,165) for use in this MRI system (100) is also proposed. Moreover, a corresponding method (500) for managing the injector head assembly (155) is proposed. A computer program (400) for implementing the method (500) and a corresponding computer program product are also proposed.

To provide a packaged medical device in which a medical device in a container is stably fixed and which can be easily opened. Specifically, provided is a packaged medical device comprising a container having an opening portion and a flange portion formed to extend outward in a peripheral portion of the opening portion, a medical device housed inside the container, and a lid member having a gas impermeable film and peelably heat-sealed to the flange portion, in which the inside of the container is set to a negative pressure to the atmospheric pressure so that the medical device is pressed by the lid member and the peel strength to the flange portion of the lid member is 2 to 50 N/in.

A dialysis valve includes a tube attached between an artery and a vein which, when elongated, simultaneously narrows in diameter at at least one location. The narrowed portion of the tube decreases the volume and velocity between the arterial and venous side of the patient to prevent damage or intimal hyperplasia on the venous side between dialysis treatments. When the valve is opened for dialysis, an unrestricted blood flow exists between the arterial and venous side, permitting a controlled, open blood flow during dialysis.

A system and method for inductive heating applications includes positioning one or more inductive heating elements in a location, delivering electromagnetic radiation, by a radiation source, to heat at least a portion of the one or more inductive heating elements, and detecting, by a detector, the heat generated by the one or more inductive heating elements. The system and method also include controlling, by a processing unit, a condition based on the detected heat.

A medical fluid suspension generating apparatus for performing medical procedures includes a Venturi-agitating tip assembly composed of a multi-channel arrangement at a proximal first end thereof and a tip at a distal second end thereof. The apparatus also includes a compressed medical fluid unit fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly and a medical solution fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly. Pressurized sclerosant or other chemical medical solution, from the compressed medical fluid unit, and the medical solution of sclerosant or other chemical medical solution are combined within the Venturi-agitating tip assembly in a manner generating an enriched medical suspension that is ultimately dispensed from the suspension delivery apparatus to spray or wash the inner wall of a lumen.

A needle cap and a dialysis circuit priming device with increased safety and convenience in the cleaning and priming of a blood circuit are provided. According to the present invention, a needle cap is provided including two needle connecting parts, and a flow path connecting the two needle connecting parts. A dialysis circuit priming device is also provided including two needles, two needle connecting parts each arranged with the two needles respectively, and a flow path for connecting the two needle connecting parts.

Methods and systems are provided for adaptive scan control. In one embodiment, a method includes upon a first contrast injection, processing acquired projection data of a subject to measure a contrast signal of the first contrast injection, estimating a time when a venous return to baseline (VRTB) of the first contrast injection is to occur based on the contrast signal, and commanding initiation of a second contrast injection at the estimated time.

Disclosed is a method of controlling operation of a medical device that regulates delivery of a fluid medication to a user. The method obtains a current sensor-generated value that is indicative of a physiological characteristic of the user, and is produced in response to operation of a continuous analyte sensor device. The method continues by: calculating a sensor quality metric that indicates reliability and trustworthiness of the current sensor-generated value; adjusting, in response to the calculated sensor quality metric, therapy actions of the medical device to configure a quality-specific operating mode of the medical device; managing generation of user alerts at the medical device in response to the calculated sensor quality metric; and regulating delivery of the fluid medication from the medical device, in accordance with the current sensor-generated value and the quality-specific operating mode of the medical device.
