MICROSPHERE CONTAINMENT SYSTEMS AND METHODS
In the present disclosure, embodiments of microbead containment systems and containment methods are disclosed. The microbead containment system may include a microsphere container, which includes walls that define a containment space in the microsphere container, and microspheres within the containment space. The walls may include at least one magnetic component configured to produce a magnetic field within the containment space. The microspheres may include a diamagnetic material. The method of containing radioactive microspheres may include loading a plurality of microspheres comprising a diamagnetic material in a container comprising one or more magnetic components. The microspheres contained in the microsphere container interact with the magnetic field in a manner that prevents direct contact of the microspheres and the microsphere container.
CATHETER WITH FLARING TIP
In the present disclosure, embodiments of flaring tip microcatheters, methods of deploying flaring tip microcatheters, and embolization treatment methods are disclosed. The flaring tip microcatheter may include a hollow shaft having a shaft lumen defined therein, a core disposed within the shaft lumen, and a tip comprising at least two petals affixed to a distal end of the core, the at least two petals comprising at least two wires wherein the core is hollow and defines a core lumen. The at least two wires may be configured to pull the at least two petals to form a flared configuration of the tip. The flared configuration of the tip may allow for laminar flow of a therapeutic agent distally from the tip.
Solution delivery device and method
The present specification discloses a solution delivery device having a container component and a plug component configured for selective engagement with the container component. The container component has an internal cavity including an elongated mixing channel containing a first constituent, and the plug component provides an internal flow path configured for introduction of a second constituent into the mixing channel for mixing with the first constituent. The plug component may be inserted within the container component partially in a first operational mode and fully in a second operational mode. The first constituent may be a drug and the second constituent a diluent, such that the drug may be lyophilized with the device in the first operational mode and reconstituted with the device in the second operational mode. Multiple devices may be employed in tandem for the co-delivery of multiple constituents. The device may be included in a kit or installed within an injector.
MULTI-CHAMBER SYRINGE
Syringes are described herein. A syringe includes a syringe body, a first plunger, a second plunger, and an inner tube. The syringe body defines a syringe cavity and a syringe port, wherein the syringe port is in fluid communication with the syringe cavity. The first plunger is disposed within the syringe cavity and defining a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. The second plunger is disposed within the syringe cavity, the first plunger and the second plunger cooperatively defining a second chamber in the syringe cavity. The inner tube comprises an inner tube lumen, wherein the inner tube and the first plunger shaft lumen define an annulus therebetween, the annulus in fluid communication with the first plunger channel and the annulus permits fluid communication between the syringe port and the first plunger channel.
Method and assembly for fluid transfer and drug containment in an infusion system
A fluid transfer assembly, drug container, and method for enabling fluid transfer in an infusion system is taught. The assembly includes a fluid container containing an infusion fluid, and a drug container. The fluid container has at least one inlet port for receiving a medical substance from the drug container. The assembly further includes at least one fluid barrier controlling fluid passage between the drug container and the fluid container. The inlet port exhibits a first luer-lock connector, and the drug a container is sealed by a cap exhibiting a second luer-lock connector for attachment to the first luer-lock connector. The fluid barrier is designed and arranged to be ruptured by an external force to allow the fluid passage.
COMBINATORIAL DRUG DELIVERY DEVICE
In one aspect, a combinatorial drug delivery device is provided for delivering a predetermined selection of drug components. The device includes a plurality of modules, each including: a body having an interior volume; a spike plate movably disposed in the interior volume, the spike plate having a protruding cannula and first and second ports. The device also includes a base tray which includes: a framework defining a plurality of wells, each of the wells formed to insertingly receive one of the modules; for each of the wells, first and second inlet ports formed to interface with the first and second ports of the module being received in the respective well; passageways to connect certain wells with adjacent wells to permit fluid flow therebetween. For each of the wells, the spike plate of the respective module being maintained in a stationary position with the module being inserted into the well.
DEVICE FOR CONVEYING BIOLOGICAL MATERIAL
A device for conveying a biological material includes a body including an aperture configured to enable connection with an outside of the body and a chamber configured to store a biological material, a plurality of conveyors accommodated in the body and configured to convey the material, and a driver configured to select one of the plurality of conveyors, align the selected conveyor with the aperture, and move the selected conveyor to the outside of the body through the aperture.
Implantable solid-liquid drug delivery apparatus, formulations, and methods of use
Embodiments provide apparatus and methods for delivering liquid form medication within the body wherein the medication is stored in solid form and then mixed with a liquid in an apparatus implanted within the body. One embodiment provides an implantable apparatus for in vivo delivery of medication comprising a housing including a reservoir, a store of solid form medication (SSM) and a pump. An SSM element is added to the reservoir along with fluid to form a medication solution comprising at least one drug. The medication solution is then delivered to a delivery site using a pumping means to pump solution from the reservoir through a delivery member such as catheter to a delivery site. Embodiments of the invention are particularly useful for delivering medication to a patient to treat a medical condition over an extended period of time without requiring the patient to take external medication.
Infuser
A device, method or kit for delivery of a treatment into a fluid flow for inhalation. More particularly, the invention relates to an infuser having a treatment chamber which receives a treatment or treatment element permeated with a treatment which mixes into a fluid flow to form a treatment vapor which egresses from the infuser.
Container for mixing and dispensing components
A container is provided. The container includes a body, a first plug, and a second plug. The body has a first end, a second end, and a bypass with a length L disposed between the ends. The first and second plugs are slideably disposed in the body and define a first compartment. A second compartment is in the body between the second plug and the second end. The second plug has a first edge; a second edge; and a plurality of primary conduits, each primary conduit extending from first openings in the side wall to second openings in the bottom surface. The bottom surface does not define a plane oriented substantially orthogonal to the longitudinal axis. A distance D extends longitudinally from the first edge to the second edge. A distance E extends longitudinally from the first edge to the first opening. DL and E<L.
