The disclosed systems and methods are configurable central nervous system (CNS) delivery solutions for therapeutics, such as genetic medicines. The systems and methods first infuse a therapeutic bolus within intrathecal space and subsequently infuse a flush fluid to move the therapeutic bolus rostrally toward a target area and achieve a desired spread in the spine and/or brain. The second location can be at a location caudal to the delivery location of the therapeutic bolus.

Enteral feeding pump systems valves assemblies therefor and related fluid flow control methods. The system includes a disposable fluid delivery set with an integral peristaltic tube section and an enteral feeding pump. The system may also include a pinching mechanism for regulating the flow of nutrient formula or water out of the fluid delivery set. Also disclosed is a flow selector valve assembly for an enteral feeding pump system, the valve assembly including a tube adapter having two input flexible tubing channels and one output tubing channel and being configured to position the flexible tubing channels in relation with a receiver. The receiver has an eccentric bearing that is moveable between a first position in which neither of the input flexible tubing channels is compressed, and a second position in which the eccentric bearing compresses one of the input flexible tubing channels therein to prevent flow therethrough.

Some embodiments provided herein relate to methods, systems and kits for providing consistent intracoronary administration of a biologic to subjects having diverse coronary anatomies. In some embodiments, the biologic is an adeno-associated virus serotype 1 (AAV1) vector encoding sarcoplasmic/endoplasmic reticulum ATPase 2a (SERCA2a) protein.

A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, an inner surface extending through the distal end and the proximal end and forming a lumen, and a side port forming a side port pathway through a sidewall of the catheter adapter and in fluid communication with the lumen. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a septum disposed within the lumen proximal to the side port pathway. A portion of the inner surface proximal to the catheter and distal to the septum may include one or more of the following: a textured surface, a channel configured to direct fluid flowing into the lumen from the side port, a protrusion extending inwardly into the lumen opposite the side port pathway, and an annular shoulder.

A treatment method is disclosed capable of reducing the burden on a patient and enhancing the effect of killing tumor cells. The method includes administering an antibody-photosensitive substance into a vein; inserting an endoscope from a mouth, a nose, or an anus and bringing the endoscope to a vicinity of a tumor after the administering of the antibody-photosensitive substance into the vein; placing an optical fiber into the tumor or in the vicinity of the tumor; irradiating at least one of the tumor, the vicinity of the tumor, or a regional lymph node with a first near-infrared ray by the optical fiber; and irradiating the antibody-photosensitive substance bound to a tumor cell membrane in the tumor cell with a second near-infrared ray after the irradiating with the first near-infrared ray, the second near-infrared ray having a shorter wavelength than that of the first near-infrared ray.

Syringe assemblies are described herein. A syringe assembly includes an assembly housing, a first syringe, a second syringe, and a connecting gear. The first syringe is disposed within the assembly housing. Each plunger is movable within the respective syringe cavity and defines a respective chamber in the respective syringe cavity, wherein the respective chamber is in fluid communication with the respective syringe port, the respective plunger comprising a respective gear rack extending longitudinally along the respective plunger. The connecting gear is rotatably coupled to the assembly housing. The connecting gear is configured to be in meshed engagement with at least one of the first gear rack and the second gear rack of the syringes.

A method to manage flushing of a catheter assembly may include providing a clamp for a fluid tube configured to be coupled to the catheter assembly. The clamp may include a sensor configured to detect the clamp is closed. The method may include starting a timer in response to the sensor detecting the clamp is closed. The method may include providing an alert in response to the timer reaching a predetermined duration of time. The alert may indicate to a clinician that the catheter assembly should be opened and flushed, which may prevent occlusion of the catheter assembly.

Provided are .sup.82Sr/.sup.82Rb elution systems that accept patient weight as a input function in order to determine an optimal quantity of radioactive rubidium-82 for delivery to a patient pursuant to an imaging scan. Also disclosed are systems that deliver a saline flush to remove residual .sup.82Rb from the system downstream of the generator, and preferably deliver the removed residual .sup.82Rb to the patient. Other disclosed systems measure the total volume of saline that flows through a .sup.82Sr/.sup.82Rb generator, a total volume of saline that flows through the generator and through a bypass line, or a total volume of saline received by a waste reservoir, in order to monitor system components so that optimal system functioning is assured.

Provided herein are the safety features for radiopharmaceutical infusion system for treatment or diagnostic purpose, wherein infusion system comprises a controller, a source of radiopharmaceutical including other components. The controller is configured to perform automated quality control steps at the start of the system during daily quality control and ensure that system complies to desired technical attributes prior to administration to patients. The quality control steps comprise calibration, breakthrough testing, checking for unauthorized connection and/or malware in the system, network or other connected devices.

A fluid injection system including a graphical user interface, a fluid control module operatively connected to the graphical user interface, a monitoring control module provided in at least one of the graphical user interface and the fluid control module, a fluid injector operatively connected to the graphical user interface and the fluid control module, at least one fluid path set in fluid communication with the fluid control module, and a hemodynamic monitoring system operatively connected to the fluid path set and the monitoring control module. The hemodynamic monitoring system may be configured to receive electrical signals regarding pressure waves formed in medical fluid directed through the fluid path set based on a location of the fluid path set in a patient's vasculature, to convert the electrical signals to pressure wave form information, and to send the pressure wave form information to the monitoring control module.
