Abstract: An insertion mechanism for a drug delivery device. The insertion mechanism includes a proximal end, a distal end, a first opening disposed near the proximal end, and a second opening disposed in the distal end. A needle or cannula assembly is disposed within a housing and has a base with a proximal surface and a distal surface and a needle or cannula coupled to the distal surface. A retraction member is disposed within the housing to maintain the needle or cannula assembly in a retracted position before movement to an extended position, the retraction member in contact with the base. Upon supplying pressure through the first opening until an amount of pressure P1 applies an application force to the proximal surface of the base that surpasses a resistive force of the retraction member, the needle or cannula assembly is moved from the retracted position to the extended position.

Abstract: Impact testing apparatuses are disclosed which simulate and measure various impact-related events associated with the operation of a drug delivery device. The impact testing apparatus may include an impactor configured to simulate a plunger rod of the drug delivery device, and a guide sleeve configured to receive a syringe corresponding to the drug delivery device. The syringe may have a proximal end, a distal end defining an outlet, and an interior chamber extending between the proximal and distal ends and carrying a plunger. Additionally, the impact testing apparatus may include an energy source configured to reduce a distance between the impactor and the plunger so that the impactor strikes the plunger. Various sensors may be included to measure characteristics of one or more impacts caused by the impactor. Methods of impact testing a syringe filled with a fluid and carrying a plunger are also disclosed.

Abstract: A drug delivery device includes a housing, a reservoir, a cannula, one or more light sources, a label, and a controller. The reservoir is disposed within the housing. The cannula is connected to the reservoir for delivering a drug from the reservoir to the patient. The light sources are disposed adjacent the exterior surface of the housing, and each serves to indicate one of one or more operational conditions of the device. The label is fixed to the housing adjacent the light sources, and includes one or more informational messages. Each informational message is aligned with one of the light sources for conveniently conveying to a user an operational condition of the device as indicated by the corresponding light source. Finally, the controller is operably connected to the reservoir and the light sources. The controller is configured to actuate the reservoir to deliver the drug, and to selectively illuminate the one or more light sources based on the operational condition of the drug delivery device.

Abstract: A drug delivery device includes a container for storing a drug having a longitudinal axis. A plunger rod aligned with the longitudinal axis of the container has a first end and a second end, where the second end is disposed within the container. A stopper is disposed in and movable relative to the container for expelling the drug, and a drive mechanism is operatively coupled to the first end of the plunger rod. The drive mechanism is configured to deliver a drive force to move the plunger rod along the longitudinal axis and through the container. A chamber disposed between a plunger rod and the stopper is adapted to oppose the drive force of the drive mechanism.

Abstract: Systems and methods for drug delivery with pressure sensitive control are disclosed. A drug delivery system may include a reservoir filled or fillable with a drug, a drug delivery device coupled to the reservoir to deliver the drug from the reservoir to a patient, a pressure sensor, an output device, and a controller. The controller may be configured to determine if the drug delivery device has completed delivering a dose of the drug to the patient, and if delivery of the dose of the drug is complete, to measure tissue back pressure using the pressure sensor. Subsequently, the controller may be configured to determine if the tissue back pressure is below a first predetermined value, and if so, control the output device at least once and/or control a mechanism to retract an administration member from the patient.

Abstract: The disclosed methods are directed to detecting polypeptide fragments (“clips”) of parental polypeptides. Parental polypeptides and clips are optionally denatured and then fractionated using a matrix. After a first elution (high molecular weight fraction), an additional elution step retrieves a low molecular weight fraction containing clips. If the clips are an appropriate size for the targeted detection method, such as mass spectrometry, then analysis of this fraction proceeds separately from the high molecular weight fraction, or the clips fraction is mixed with the proteolyzed high molecular weight fraction before analysis. However, if the clips are too large for the intended analytical method(s), then the clips are also proteolyzed. The digested high molecular weight and low molecular weight fractions can be analyzed separately or combined. Analysis of combined samples favors clip quantitation because the clips are analyzed together with the remaining counterpart of the parental polypeptide.
