Patent number: 11369736Abstract: An insertion mechanism for a wearable drug delivery device that deploys a small gauge flexible cannula with support of a coaxial rigid trocar or hollow needle. After insertion, the trocar or hollow needle is withdrawn leaving the cannula in place for drug delivery. The insertion mechanism may also include an insertion mechanism housing having a proximal and distal end, a manifold configured to fluidly connect the hollow interior of the cannula and the fluid pathway connector, and a manifold guide carrying the manifold and movable between a first position and a second position. A hub carries the trocar and is removably connected to the manifold guide. An insertion biasing member may be initially retained in an energized state between the proximal end of the insertion mechanism housing and the hub, and a retraction biasing member may be initially retained in an energized state between the hub and the manifold guide.Type: GrantFiled: February 13, 2018Date of Patent: June 28, 2022Assignee: AMGEN INC.Inventors: Erich Coiner, Paul Faucher, Adam B. McCullough, Antonio Ubach

Patent number: 11357913Abstract: Valves and medication delivery systems including valves are described herein. A valve includes a valve body and a valve element. The valve body defines a first flow path, a second flow path, and a catheter flow path. The valve element is disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first flow path and the second flow path in a priming position, and is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position.Type: GrantFiled: May 3, 2019Date of Patent: June 14, 2022Assignee: CareFusion 303, Inc.Inventors: Todd Oda, George Mansour, Eugene Mason, Dylan Beyhl

Patent number: 11338110Abstract: An elongated steerable system for guiding a catheter or an endoscope, comprising: an elongated flexible member including, along at least a part of its longitudinal axis, at least one projection which, in transversal section, projects from the elongated flexible member; the at least one projection having a distal end and a proximal end, and defining, in transversal section, two lateral sides projecting from the elongated flexible member; and a wire; wherein the at least one projection includes at least one transverse retaining and passing element near the distal end of the projection, the retaining and passing element extending transversely to the lateral sides of the projection; and the wire passes through the retaining and passing element alternatively from one lateral side of the projection to the other lateral side of the projection, where adherence between the wire and the retaining and passing element retains the wire.Type: GrantFiled: March 16, 2018Date of Patent: May 24, 2022Assignee: BASECAMP VASCULARInventor: Jean-Baptiste Cazeneuve

Patent number: 11331431Abstract: A syringe assembly having a barrel for storing a medication and a stopper positioned within the barrel and having an opening, the stopper separating the proximal and distal sections of the barrel. A plunger is movable axially within the barrel. A cover extends radially from the plunger, the cover movable within the barrel from an open position to a closed position, wherein in the open position the cover exposes the opening in the stopper to enable the medication to flow within the barrel from the proximal section to the distal section and in the closed position the cover covers the opening to prevent the flow of medication from the proximal to the distal section.Type: GrantFiled: November 1, 2019Date of Patent: May 17, 2022Assignee: Gemini Medical, Inc.Inventor: Philip Bunsick

Patent number: 11318247Abstract: A peristaltic infusion pump with improved low flow performance. The pump includes a cam shaft having cams offset in an axial direction, pump fingers that engage a tube, each finger coupled to a respective cam, the fingers creating a pumping region and an occlusion region within the tube, a motor coupled to the cam shaft, a memory, and a controller. The controller implements cam rotation instructions received from the memory to cause the pump to position the fingers in the occlusion region prior to beginning an infusion therapy to deliver fluid to patient through the tube at a patient fluid delivery rate, rotate the cam shaft to transition the fingers from the occlusion region to the pumping region at a startup rate that is faster than a patient fluid delivery rate, and rotate the cam shaft at the patient fluid delivery rate in the pumping region.Type: GrantFiled: December 6, 2019Date of Patent: May 3, 2022Assignee: B Braun Medical Inc.Inventors: Sean Buxton, Benjamin Vespone

Patent number: 11224694Abstract: An automatic injection device including an injection syringe equipped with a syringe body and with a piston rod mounted movably in this syringe body so as to cover an injection stroke, a piston control member capable of changing between a configuration in which it is in engagement with the piston rod and a configuration in which it is disengaged from this piston rod, mechanism for moving the piston control member between its two configurations with respect to the piston rod. The mechanism for moving the control member between its two configurations includes a camway carried by a disengagement member and a cam carried by the control member. The disengagement member is movable with respect to the piston rod and the syringe body after the end of the injection stroke, in such a way as to cause the camway to interact with the cam.Type: GrantFiled: June 13, 2017Date of Patent: January 18, 2022Inventors: Pascal Dugand, Kevin Stamp

Patent number: 11202862Abstract: A device and a method for adjustable quantitative injection of high-pressure gas are provided, wherein the gas may have a pressure of 5 MPa or more than 5 MPa. The gas may be directly communicated with a gas tank in the mechanism or an external gas source, flows through corresponding valves, and is charged into a predetermined or adjustable reservoir. Alternatively, the valve may be time-controllable, and does not need the reservoir. The gas is ejected through a nozzle selected based on depth or range of injection, wherein a one-way valve is disposed between the nozzle and the body to prevent contamination due to backflow. The manipulator can exert an appropriate force onto a target portion of a human for gas injection, and when the injection is done, a biasing member can automatically return the mechanism to its original state, ready for the next injection.Type: GrantFiled: January 29, 2018Date of Patent: December 21, 2021Inventor: Guo-Luen Huang

Patent number: 11083839Abstract: An infusion arrangement for administering a medical fluid includes a pump apparatus with an elastomeric membrane which forms a pump volume. The elastomeric membrane is elastically extended in a fill state, filled at least partially with medical fluid, of the pump volume and produces a delivery pressure on the pump volume. An infusion line is connected to the pump volume and provided with a patient access for fluid-conducting connection. A main fluid channel transfers medical fluid from the pump volume to the patient access. A monitoring device is connected to the infusion line and configured for monitoring the pump apparatus. The monitoring device has a differential pressure-measuring element connected to the main fluid channel and designed such that differential pressure formed along a channel portion of the main fluid channel can be detected by the differential pressure-measuring element and a delivery rate of the medical fluid can be indicated.Type: GrantFiled: July 9, 2019Date of Patent: August 10, 2021Assignee: B.
