Embodiment Construction

[0019] Figure 1-5 An exemplary embodiment of a drug delivery device 1 is shown. In this exemplary embodiment, the delivery device 1 may be a syringe used alone or in conjunction with an automatic injection device. The delivery device 1 is shown with a substantially cylindrical barrel 3 . The barrel 3 contains medicines and the like to be administered to the body part to be treated or diagnosed, such as the eye 2 . Examples of such medications are steroids or monoclonal antibodies used to treat macular degeneration. Those skilled in the art will appreciate that various drugs and / or therapeutic substances and / or implantable devices may be administered using the delivery device 1 .

[0020] A plunger 5 is disposed within the barrel 3 and a needle 7 is coupled to the distal end of the barrel 3 . When distally directed pressure is applied to plunger 5 , plunger 5 moves axially (distally) within barrel 3 and expels the drug through needle 7 .

Abstract

Described is a medicament delivery device (1) comprising a needle (7) and a layer (9) of a composition coupled to at least a portion of the needle (7). The composition has a low viscosity and a low surface tension.

Description

technical field [0001] The present invention relates to a drug delivery device, such as a device for intraocular injection, and a needle for the drug delivery device. Background technique [0002] Many sight-threatening ocular diseases or disorders require the use of drug delivery devices to deliver drugs (pharmaceutical, biologic, etc.) back section. One such intraocular delivery technique is by intraocular injection into the vitreous. [0003] Drug delivery devices (eg, syringes) may be used to administer a therapeutic substance to the eye, eg, of a mammal having an ocular disorder or disease. The device may include a distally located needle arrangement that pierces the eye for drug delivery. [0004] Treatment programs provided to patients with certain ocular diseases and conditions often involve the delivery of drugs to the interior of the eye at regular intervals over an extended period of time, possibly months or even a lifetime. Accordingly, it would be desirable ...
