Patent number: 7217253Abstract: A device and two-step sequential method for providing medication for injection and infusion by a jet injector includes a cassette which connects an injector system to a reservoir. The cassette forms a fluid pathway at an interface of a cassette lower body and a cassette upper body. The cassette also forms an impulse chamber with a nozzle leading therefrom. The fluid pathway interconnects the reservoir with the impulse chamber. The medication flows from the reservoir along the fluid pathway and into the impulse chamber. Force from an impulse generator drives the fluid medicament from the impulse chamber through the nozzle, out an orifice in a tip of the nozzle, and into the skin of a patient. To prevent the pressure waves generated by the jet injector from damaging a glass reservoir, the fluid pathway is formed with pressure attenuators.Type: GrantFiled: September 12, 2003Date of Patent: May 15, 2007Assignee: Avant Medical Corp.Inventors: John B.

Publication number: 20050020969Abstract: An integral data logging system for a jet injector includes at least one electrical switch that changes state (e.g. from OFF to ON) during an injection procedure. The switch(es) are connected to an electrical circuit having a microprocessor, a clock and an electronic memory. When a switch changes state, this information along with the applicable date and time is recorded in the electronic memory. A communications link is provided to upload the stored data to a remote computer for subsequent manipulation and analysis to determine compliance with a prescribed dosing regimen. In one implementation, the injection duration is logged by using a trigger release switch and an end-of-stroke switch. The end-of-stroke switch is configured to change state after the drive bar of the injector transits through the injector tube. The injection duration is indicative of dose amount and can be used to distinguish between valid and invalid injections.Type: ApplicationFiled: August 12, 2004Publication date: January 27, 2005Inventors: John Slate, Michael Burk, Lanny Gorton

Patent number: 6645169Abstract: A method for injecting a fluid medicament into a patient uses a syringe having a plunger that can be advanced into the syringe chamber. As the plunger is advanced, the medicament is expelled from the chamber through an injection tube that extends from the chamber. Preferably, the injection tube is formed as a cone-shaped funnel with a taper of generally decreasing radius in a distal direction. The steps for the method include creating a gas pocket in the distal portion of the injection tube. Then, as the plunger is advanced into the chamber to accelerate the fluid medicament through the injection tube, the gas pocket allows the accelerating fluid medicament to gain momentum. The change in this momentum as the fluid medicament collides with the skin will generate an impulse force that is manifested as an initial pressure spike. This pressure spike creates a hole in the skin of the patient as the fluid medicament exits the tube.Type: GrantFiled: September 20, 2000Date of Patent: November 11, 2003Assignee: Avant Drug Delivery Systems, Inc.Inventors: John B.

Patent number: 6440110Abstract: An apparatus and method for collecting a large volume of blood from an umbilical cord in a sterile environment are shown and described. A housing having an inner region adapted to retain an umbilical cord in a desired location is provided, the housing having an opening through which the cord extends from the inner region of the housing to a region external to the housing. The cord is cut by a blade coupled to the housing, either by the motion of the blade from a first position to a second position, or by the movement of two portions of the housing from a first extended position to a second collapsed position. The newly cut end of the umbilical cord falls and hangs freely in the inner region of the housing, blood flowing from the placenta and umbilical cord via gravity into a blood collection region of the housing. The blood collection region may be flexible, and may be coupled to a conventional blood collection bag.Type: GrantFiled: December 18, 2000Date of Patent: August 27, 2002Assignee: Children's Hospital Medical Center of Northern CaliforniaInventors: Franciscus A.

Patent number: 6406456Abstract: An injector for the intra-muscular, subcutaneous, or intra-dermal delivery of a fluid medicament to a patient includes a cylindrical member which has a closed end and an open end, and which is formed with a compartment between these two ends. An injection tube extends from the closed end through the cylindrical member and into the compartment. A suction pump is connected in fluid communication with the compartment to create a partial vacuum in the compartment when the open end of the cylindrical member is held against the skin of the patient. Due to this vacuum, skin of the patient is drawn into the compartment to position the tip of the injection tube against the skin. Also, skin that is adjacent the tip is drawn by the vacuum into the compartment. This stabilizes the skin around the injection tube tip and thereby minimizes any movement of skin relative to the tip during an injection of fluid medicament into the patient.Type: GrantFiled: June 8, 2000Date of Patent: June 18, 2002Assignee: Avant Drug Delivery Systems, Inc.Inventors: John B.
