A disposable syringe for use with a pneumatic driver. The syringe has an elongated barrel with a cap secured to the proximal end that has a through bore. A filter is secured to the cap interior of the barrel that covers an opening in the through bore interior of the barrel. The pneumatic driver includes a source of pressurized air; a support for receiving and locating the syringe; and a supply block configured to receive pressurized air from the source and having an outlet for delivery of pressurized air. The supply block is movable between a first position spaced apart from the cap of the syringe and a second position in contact with the cap with fluid communication being established between the outlet of the supply block and the through-bore in the cap.

A drug delivery device, in the form of an injector, may include one of a number of systems for limiting the delivery of a medical fluid or drug product in case of movement of (e.g., removal of) the injector relative to the patient as determined by a proximity sensor. The drug delivery system may in the alternative or in addition include systems for indicating the amount of medical fluid or drug product delivered (or not delivered) in case of movement of (e.g., removal of) the injector relative to the patient as determined by the proximity sensor. The injector may be, for example, an on-body injector or an hand-held autoinjector.

A medical fluid suspension generating apparatus for performing medical procedures includes a Venturi-agitating tip assembly composed of a multi-channel arrangement at a proximal first end thereof and a tip at a distal second end thereof. The apparatus also includes a compressed medical fluid unit fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly and a medical solution fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly. Pressurized gas, from the compressed medical fluid unit, and the medical solution are combined within the Venturi-agitating tip assembly in a manner generating an enriched medical suspension that is ultimately dispensed from the suspension delivery apparatus.

An exemplary embodiment of an injector includes a trigger mechanism, an energy source, and a user-operable firing-initiation member. The trigger mechanism can include a floating trigger member having a retaining portion, a ram assembly having a ram configured to pressurize a medicament container for expelling a medicament therefrom, the ram assembly further having a floating trigger engagement member configured to engage the retaining portion of the floating trigger member when the floating trigger member is in a pre-firing condition. The energy source can be associated with the ram for powering the ram to expel the medicament, and the user-operable firing-initiation member can be operable for causing an axial rotation of the floating trigger member from the pre-firing condition to a firing condition in which the floating trigger engagement member is released from the retaining portion to allow the energy source to fire the ram.

An apparatus includes a housing, a medicament container, an actuator, and a biasing member. The actuator is configured to move the medicament container within the housing when the actuator is moved from a first configuration to a second configuration. The actuator includes a gas container and a puncturer. When the actuator is in the first configuration, a portion of the puncturer is disposed apart from the gas container. When the actuator is in the second configuration, the portion of the puncturer is disposed within the gas container. The gas container has a longitudinal axis offset from a longitudinal axis of the medicament container. The biasing member is configured to bias the actuator toward the second configuration.

The invention relates to a medical high-pressure injector for injecting a liquid provided in a syringe (2.1, 2.2) into a patient, wherein the injector has at least one syringe holder (10) with an associated drive unit for the syringe (2.1, 2.2) held therein as well as connecting lines for transmitting the liquid from the syringe (2.1, 2.2) into a patient tube and/or for filling the syringe (2.1, 2.2) that is held in the syringe holder (10), wherein the connecting lines are embodied in an interchangeable control cassette (3) and the injector has a cassette holder (11) with a receiving chamber (110) that can be opened and closed, into which the control cassette (3) can be inserted.

A needleless injection apparatus is provided which forms a suitable contact state between an injection opening and an injection object. The needleless injection apparatus is provided with an expansible bag body, a needleless syringe including no injection needle, and a gas supply unit for supplying the expansion gas to the bag body. Here, the needleless syringe has a nozzle portion for injecting an injection objective substance toward the injection object surrounded by the bag body. Then, the bag body includes a first bag portion arranged at any of locations except an arrangement location of the needleless syringe so as to pressurize the injection object by expansion, and a second bag portion arranged at a location at which the nozzle portion is sandwiched between the second bag portion and the injection object so as to push the injection opening to an injection object side by expansion.

A needleless injector pressurizes a substance to be injected having an ejection pressure defined as a pressure of the substance to be injected ejected through an ejection port. The ejection pressure is raised to a first peak pressure after pressurizing is started, is lowered to a pressure lower than the first peak pressure afterward, and then is raised to a second peak pressure again. An on-completion reached depth that is an on-completion reached depth of the substance when the pressurizing portion completes pressurizing is adjustable, the on-completion reached depth being increased along with increase of the first peak pressure and being increased along with reduction of a length between peaks from a first timing at which the ejection pressure reaches the first peak pressure to a second timing at which the ejection pressure reaches the second peak pressure.

Aspects of the present disclosure are directed to a medical implant introducer (100) and methods of its use. The introducer (100) may include a handle (120), an implant-holding cavity disposed distally from the handle (120), a fluid supply conduit (122) fluidly coupled to an interior portion of the implant-holding cavity, and a distal nozzle (110) having a proximal portion, a distal portion, a middle portion in between the proximal portion and the distal portion, the middle portion having a tapered profile such that the proximal portion is larger than the distal portion, and a distal opening (112), wherein an implant in the implant-holding cavity may be expelled from the introducer (100) through the distal opening (112).
