Abstract: Multiphase microspheres for radioembolization include two-phase microspheres and three-phase microspheres prepared by a microfluidic process. The multiphase microspheres include a primary phase and a first secondary phase surrounded by the primary phase. The primary phase includes a first resin. The first secondary phase includes a second resin and at least one of a radioactive isotope or a compound including at least one radioactive element. Three-phase microspheres additionally include a second secondary phase discrete from the first secondary phase and also surrounded by the primary phase. The second secondary phase may be a gas such as air. The microspheres may be formed by a microfluidic process.

Abstract: The present invention relates to a container adapter (9) for a medical delivery device (1). The medical delivery device (1) has a container seat (53) for holding a container (8) in a predefined position, a dosage chamber (61), a dosing mechanism to transfer a liquid from the container (8) held in the container seat (53) to the dosage chamber (61) and a lock mechanism (530) adapted to prevent operation of the dosing mechanism when no container (8) is held in the container seat (53) and to allow operation of the dosing mechanism when the container (8) is held in the container seat (53). The container adapter (9) comprises an adapter container seat (91) arranged to hold a container (8) in a predefined position; a joint structure (92) arranged to be detachably positioned in the container seat (53) of the medical delivery device (1) and to connect the adapter container seat (91) to the dosing mechanism of the medical delivery device (1) when the joint structure (92) is positioned in the container seat (53) of the medical delivery device (1); and an unlock member (93) adapted to activate the lock mechanism (530) of the medical delivery device (1) such that operation of the dosing mechanism is allowed when the joint structure (92) is positioned in the container seat (53) of the medical delivery device (1). The present invention also relates to a delivery assembly comprising a container adapter (9) as above introduced and a corresponding medical delivery device (1) receiving in its container seat (53) the joint structure (92) of the container adapter (9); as well as to a method of delivering a liquid to a patient from different containers (8), a first container being preliminarily arranged in the adapter container seat (91) of the container adapter (9) and a second container being positioned in the container seat (53) of the medical delivery device (1) after removal of the container adapter (9) therefrom.

Abstract: A syringe for injection of fluid into the vitreous humor of an eye has a body that has, formed therein, an injection barrel and an extraction barrel, both of which have volumes that vary in response to movement of primary and secondary plungers that, are coupled to each other by a coupler. Two parallel needles, an extraction needle and an injection needle, emerge from the distal end of the body. Movement of the primary plunger injects fluid into the vitreous humor while at the same time causing the secondary plunger to extract the same volume of fluid from the vitreous humor, thus maintaining intraocular pressure.
