An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.

A drive assembly for a drug delivery device is provided, including a piston rod which is moveable in a distal direction in order to deliver a dose of medication, and including a drive element which is configured to cause a movement of the piston rod. The drive assembly further includes a decelerating mechanism which is configured to decelerate the movement of the drive element such that the movement of the piston rod is decelerated during the dispense of a dose. The decelerating mechanism includes a decelerating element which is fixed with respect to a housing of the drug delivery device at least during the dispense of a dose and the drive element, wherein the drive element is configured to rotate with respect to the housing during the dispense of a dose, and wherein the decelerating element and the drive element rub against each other during the dispense of a dose.

Catheters for infusion of cardiovascular fluids into blood are disclosed. The cardiovascular fluid may, for example, comprise water highly supersaturated with a gas such as oxygen. Each catheter comprises one or more capillary tubings (or capillaries) through which a cardiovascular fluid flows. The distal end of each capillary is mounted (e.g., potted) preferably flush with an external surface of a catheter sidewall, while the proximal end of each capillary is in fluid communication with a cardiovascular fluid flowing through the lumen of the catheter. The combination of the catheter shape and the orientation of the distal end of each capillary relative to the longitudinal axis of the catheter provides control over the mixing pattern of the cardiovascular fluid with blood flowing within a vascular space such as an aorta.

Injection devices for delivering pharmaceutical formulations into the eye are described. The devices may be integrated to include features that allow safe and atraumatic manipulation of the devices with one hand. For example, accurate placement, including proper angulation, of the device on the eye and injection of a pharmaceutical formulation into the eye can be performed using one hand. The devices may also include improved safety features. For example, the devices may include an actuation mechanism that controls the rate and depth of injection into the eye. Some devices include a dynamic resistance component capable of adjusting the amount of pressure applied to the eye surface. Related methods and systems comprising the devices are also described.

A cassette for use with an injector has a housing, and a cassette identification arrangement (cassette ID) defining a code containing information about the cassette that is detectable and decipherable by an injector. The cassette may further have a sleeve movably disposed within the housing, for holding a drug container, and a locking arrangement for interlocking the sleeve with the housing. The cassette may further have an aperture in the housing, and a cassette cap for removing a needle shield of the drug container. The cassette may have an anti-bending structure to prevent bending or flexing of the cassette cap. The injector may have a processor for controlling operational parameters of the injector and a detector communicatively coupled with the processor for detecting and communicating the cassette ID to the microprocessor to decipher the code defined therein. Also, a method of injecting a drug into a patient with an injector, wherein the sequence of actions performed by the user are controlled. Still further, a method of treating a patient in need thereof wherein a cassette containing a drug is provided and administered to the patient using an injector.

A smart vial adapter is capable of measuring the dose of a drug that is withdrawn from a vial, measuring the time of a dose capture event, monitoring the vial temperature, measuring the amount of motion or perturbation the vial is subjected to, capturing various other parameters that can provide additional insights associated with the drug or the amount of the dose being drawn from the vial, and communicating the recorded information to a companion application on a computer, smartphone or other device. Related methods are also disclosed and claimed.

A differential pressure limiter (226) for limiting a differential fluid pressure of cryogenic fluid (228) during a cryoablation procedure includes one or more of a fluid source (216), a pressure regulator (230), one or more proportional valves (232) and a backpressure regulator (234). The fluid source (216) selectively retains cryogenic fluid (228). The pressure regulator (230) receives cryogenic fluid (228) from the fluid source (216) and regulates a fluid pressure of the cryogenic fluid (228). The proportional valve(s) (232) receives cryogenic fluid (228) from the pressure regulator (230) and at least partially controls a flow rate of the cryogenic fluid (228). The backpressure regulator (234) receives cryogenic fluid (228) from the proportional valve(s) (232) and manually and/or automatically changes and/or decreases the differential fluid pressure of the cryogenic fluid (228) across the proportional valve(s) (232) and/or limits the differential fluid pressure across the proportional valve(s) (232) within a predetermined range.
