Delivery system for delivering a drug depot to a target site under image guidance and methods and uses of same
a delivery system and drug depot technology, applied in the direction of prosthesis, surgery, infusion syringes, etc., can solve the problems of inability to control the motion of the needle in these devices, increase the chance that the device will jam and fail to eject, and other prior art devices also suffer from inaccurate placement of the drug depot, so as to achieve sufficient pressure within the stylet

Benefits of technology
This patent describes a device that can be used to deliver a drug to a specific part of the body. It has a mechanism that creates pressure in the device to push the drug out. The device also has a solid metal rod that can be used to pierce tissue before the delivery device is inserted. The device and the needle used to insert it can be seen using imaging techniques. The technical effect of this patent is to provide a tool for delivering drugs accurately and safely to specific parts of the body.
Problems solved by technology
Unfortunately, it is not possible to control the motion of the needle in these devices because the needle will automatically retract upon activation of the trigger.
The complex spring loaded propelling system and trigger of these devices increase the chances that the device will jam and fail to eject the drug depot when required, or deposit the drug depot in a less than optimal site.
Other prior art devices also suffer from inaccurate placement of the drug depot due to the limited control over where the drug is deposited.

Embodiment Construction
[0026]For the sake of clarity and to avoid ambiguity, certain terms are defined herein as follows.
[0027]The term “comprising” means “including without limitation.” Thus, a system, device, or component comprising a list of elements may include additional elements not expressly recited. The term “consisting of” means “including the listed elements and such additional elements as may be normally present in the recited elements.” Elements that would normally be present in a recited element will be apparent to the person of ordinary skill in the art. For example, a “needle” will necessarily have a proximal and a distal end. The term “consisting essentially of” means “consisting of” (as defined herein) the listed elements plus such additional elements as would not materially affect (positively or negatively) the basic and novel properties of the invention. By “basic and novel properties” is meant the ability of the systems, devices and methods according to the invention to deliver a drug ...

A delivery system for delivering a drug depot to a site within a patient, the system comprising: a cannula; a delivery stylet configured and dimensioned to be receivable by and slidable forwardly and backwardly within the cannula including to a position wherein a distal portion of the stylet protrudes beyond the distal end of the cannula; a drug depot retainable by the stylet at the distal end of the stylet, the drug depot being visualizable by a diagnostic imaging beam or modality; and an actuator for ejecting the drug depot from the stylet to a site within the body using fluid pressure. Also disclosed are methods using, and uses of, the delivery system, including for treating scoliosis.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. 62 / 629,769, filed Feb. 13, 2018, the entirety of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to devices or delivery systems for drug depots and methods for delivering drug depots to inside an animal, including humans.BACKGROUND OF THE INVENTION[0003]Drugs may be delivered to patients by a variety of methods including oral, intravenous, intramuscular, inhalation, topical, subcutaneous delivery or delivery directly or locally to the treatment site (e.g., intrathecally, intraspinally, intraarticularly, etc.). The method of delivery chosen depends, among other things, upon the condition being treated, desired therapeutic concentration of the drug to be achieved in the patient and the duration of drug concentration that must be maintained.[0004]Drug depots have been developed which allow a drug to be introduced or administered to sites beneath the ...
