Patent number: 11285266Abstract: A drug delivery device includes a reservoir, a drug delivery member in fluid communication with the reservoir, and a plunger disposed in and moveable relative to the reservoir. A plunger rod has a mass MP and is movable from (i) a first position, where the distal end of the plunger rod is spaced apart from the plunger to (ii) a second position, where the distal end of the plunger rod contacts the plunger. A drive mechanism is coupled to the proximal end of the plunger rod and is configured to deliver a drive force FD to move the plunger rod from the first position to the second position. A ratio of the mass of the plunger rod to the drive force of the drive mechanism (MP/FD) is in a range of approximately a value greater than 0 kg/kgf to approximately 0.05 kg/kgf.Type: GrantFiled: May 15, 2017Date of Patent: March 29, 2022Assignee: AMGEN INC.Inventors: Sean Fitzgibbon, Julian Jazayeri

Patent number: 11260176Abstract: An autoinjector (100?) for expelling a single dose of a drug from a held cartridge (600) comprising a piston (630). The autoinjector includes a needle shield (350, 380?) axially movable from an initial extended position via a triggering position to a trigger release position. The needle shield (350, 380?) is operatively coupled to a plunger release element (320?, 1320) cooperating with a plunger (310, 400) to define a releasable retaining mechanism that retains the plunger release element (320?, 1320) threadedly engaged with a base thread component (204?, 1204) in a predefined relative rotational and axial position and against rotational bias provided by an actuator (330). The needle shield (350, 380?) is configured for operating the retaining mechanism to release the retaining of the plunger release element (320?, 1320) and the base thread component (204?, 1204) from the predefined relative rotational and axial position upon the needle shield (350, 380?) being moved into the trigger release position.Type: GrantFiled: December 29, 2016Date of Patent: March 1, 2022Assignee: Novo Nordisk A/SInventor: Soeren Kjellerup Hansen

Patent number: 11253287Abstract: A device and method for establishing retrograde blood flow during recanalization of a vessel having a targeted blockage. While in a collapsed state an occluding component is introduced distally intravascularly traversing the targeted blockage to its distal side. Then, the occluding component transitions to an expanded state having an enlarged diameter forming a seal with an internal wall of the vessel prohibiting anterograde blood flow beyond the expanded occluding component. Retrograde blood flow is thereby established in a region of the vessel bound at one end by the occluding component and at an opposite end by the targeted blockage by dispensing a flushing fluid into the region of the vessel.Type: GrantFiled: October 4, 2018Date of Patent: February 22, 2022Assignee: NEURAVI LIMITEDInventor: Ray McCarthy

Patent number: 11246983Abstract: An infusion device includes a pump for pumping a medical fluid from a fluid container through a delivery line towards a patient at a flow rate, a sensor for measuring a force on the pump or the delivery line, and a processor device configured to derive, from the force measured by the sensor, a pressure value indicative of the pressure in the delivery line and to compare the pressure value to a threshold value for determining whether an occlusion in the delivery line is present. A storage device stores a compliance value associated with the pump and/or the delivery line, and the processor device is configured to compute, from the stored compliance value, the flow rate and the threshold value, an estimate of a duration between the time of an occurrence of an occlusion and the time at which the pressure value exceeds the threshold value.Type: GrantFiled: July 6, 2016Date of Patent: February 15, 2022Assignee: Fresenius Vial SASInventor: Remy Wolff

Patent number: 11134980Abstract: An introducer needle assembly including a compressible section between the rigid needle and the hub. Once the vessel is entered as determined by blood entering the syringe, the compressible section of the introducer needed is occluded by compressing the section with the thumb and a finger. Neither blood for air can pass. Since the compressible section is in a flattened area it is easier to hold the needle while the syringe is unscrewed. The operator then can begin threading a guidewire down the divide which is now easier to enter because blood is not coming out of the hub thus obscuring the lumen.Type: GrantFiled: June 26, 2019Date of Patent: October 5, 2021Assignee: MEDICAL COMPONENTS, INC.Inventors: J. Daniel Raulerson, Mark S. Fisher
