Problems solved by technology

Many of the devices described in patent literature (eg WO 2008 / 084064 and US 2007 / 0005016) are also part of multi-component systems that are often time consuming to assemble and use
The increased procedure time associated with these devices can in turn increase the risk of complications
Furthermore, having to manipulate many parts inherently increases the risk of complications due to user error

Embodiment Construction

[0061] Described herein are handheld devices, methods, and systems for delivering pharmaceutical formulations into the eye, eg, by injection. The device may integrate (combine) various features into a single device that may facilitate, for example, delivery of a pharmaceutical formulation into the eye in a safe, sterile, and precise manner. Thus, such features can be integrated into a single device that can aid in proper placement on the eye, aid in positioning to reach the intraocular space at the proper angle, regulate or control intraocular pressure, and / or aid in reducing the pressure of the eye (for example, due to injection Trauma to the sclera and intraocular structures is minimized. The device can be configured in whole or in part to be disposable.

[0062] I. Equipment

[0063] In general, the integrated devices described herein include a housing sized and shaped to facilitate operation with one hand. Typically, the housing has proximal and distal ends, and an ocul...

Abstract

Injection devices for delivering pharmaceutical formulations into the eye are described. The devices may be integrated to include features that allow safe and atraumatic manipulation of the devices with one hand. For example, accurate placement, including proper angulation, of the device on the eye and injection of a pharmaceutical formulation into the eye can be performed using one hand. The devices may also include improved safety features. For example, the devices may include an actuation mechanism that controls the rate and depth of injection into the eye. Some devices include a dynamic resistance component capable of adjusting the amount of pressure applied to the eye surface. Related methods and systems comprising the devices are also described.
