摘要:
A drug cartridge is provided for delivering a drug pellet to a site beneath the skin of a patient, the drug cartridge comprising: two or more chambers, each chamber holding a drug pellet and having a proximal end and a distal end, the proximal end of the chamber having an opening to receive the drug pellet and a plunger, the distal end of the chamber having an opening for receiving the plunger and passage of the drug pellet, a bulking agent disposed within at least a portion of each chamber, wherein movement of the plunger to an extended position moves the drug pellet within the chamber of the cartridge out the distal end of the chamber and out of the drug cartridge. In some embodiments, instead or with the bulking agent pierceable superior and inferior covers are used to contain the drug pellets.

A multiple component cartridge includes a barrel defining a chamber and a longitudinal axis. A first plunger is disposed within the chamber and in sealing engagement with the barrel. The first plunger includes at least one member and is movable relative to the barrel such that the at least one member is configured for movement relative to the first plunger to facilitate passage of at least a first component through the first plunger. A second plunger is disposed within the chamber and in sealing engagement with the barrel. The second plunger includes at least one member and is movable relative to the barrel such that the at least one member of the second plunger is configured for movement relative to the second plunger to facilitate passage of at least a second component through the second plunger.

Drug depot delivery devices and methods for delivering a drug depot to a site beneath the skin of a patient are provided. In various embodiments, a device for delivering a drug depot to a site beneath the skin of patient is provided, the device comprising: a cannula capable of insertion to the site beneath the skin of the patient and having an opening for passage of the drug depot; a drug cartridge comprising at least two chambers, wherein each chamber is configured to store and release a drug depot into the cannula when the cannula is aligned with a first chamber and the plunger. In some embodiments, the drug depot delivery device and methods provide dial-a-dose technology for delivering the drug depot to the target tissue site.
摘要:
Drug depot delivery devices and methods are provided for delivering one or more drug depots to one or more sites beneath the skin of a patient with or without repositioning the cannula. The device has a cannula capable of insertion to the site beneath the skin of the patient and one or more side port openings for delivering a drug depot. The side port openings are spaced a distance from the blunt tip, which will allow the user to implant at a set distance from a nerve. The device may also include an electronic monitor for detecting the proximity of the tip of the cannula to a nerve. In some embodiments, a method of delivering a drug depot is provided by detecting the nerve and delivering the drug depot at or near the nerve.
