  • Publication number: 20210128842
    Abstract: An autoinjector apparatus is disclosed which comprises a single-use cassette and an autoinjector. The cassette comprises a housing and a sleeve movably disposed in the housing. A syringe may be disposed in the sleeve and secured therein with a lock cap. The lock cap is affixed to a distal end of the sleeve and contacts the distal end of the syringe. A shield remover extends through an opening in a proximal end of the housing for removing a needle shield which covers a needle of the syringe. A cassette identification arrangement is provided on a surface of the housing to enable the autoinjector to identify the cassette. The autoinjector is provided with a detector for reading the cassette identification arrangement.

  • Patent number: 10786629
    Abstract: 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.

  • Patent number: 10758683
    Abstract: A drug delivery system includes a reservoir and a drug delivery device coupled to the reservoir. The drug delivery device also may include at least one temperature-sensitive component and a lock having locked and unlocked states. The system further includes an output device, and a controller coupled to the lock and the output device. The controller may also include a temperature sensor, or may be coupled to the temperature sensor. The controller is programmed or configured to determine if the temperature of a drug in the reservoir or of the temperature-sensitive component exceeds an upper limit or is below a lower limit, and to activate the lock in either event. The controller is also programmed or configured to determine, directly or indirectly, if the temperature subsequently is between the upper and lower limits, and to unlock lock as a consequence.

  • Patent number: 7744559
    Abstract: A system and method for infusing a drug under continuous positive pressure (such as convection enhanced deliver) to a target tissue to be treated is particularly useful for post-resection anticancer drug therapy. The system comprises a drug infusion catheter having an expandable device which is expanded within the target tissue such that the target tissue conforms to an outer surface of the expandable device, thereby creating a form of seal around the target volume in order to maintain an effective drug pressure gradient within the target tissue. The system further comprises a sensor to measure a parameter which can be correlated to the degree of conformance between the target tissue and the outer surface of the expandable device. The sensor is coupled to a feedback control system to determine whether there is a loss of conformance, and to adjust the expansion of the expandable device in order to maintain good conformance.
