DUAL CHAMBER DISPENSING DEVICE
Described are single-use dispensing devices with a dry chamber containing lyophilized material, a wet chamber containing reconstituting solution, a breaking chamber positioned between and attached to the dry chamber and a first end of the wet chamber. The breaking chamber includes a leak-proof frangible seal that prevent mixing of the lyophilized material and the reconstituting solution until the frangible seal is broken.
Therapeutic agent delivery device with convergent lumen
An apparatus has a first fluid conduit, a second fluid conduit, a connector member, an first tubular member, a second tubular member, and an inner cannula. The connector member has first and second passageways in which the first and second fluid conduits are positioned, respectively. A portion of the second tubular member is positioned within the lumen of the first tubular member. A proximal portion of the inner cannula is fixedly secured within the lumen of the first tubular member. The inner cannula lumen is in fluid communication with the first and second fluid conduits via the lumen of the first tubular member and the lumen of the second tubular member. The inner cannula may be inserted into the subretinal space of a human eye to deliver a leading bleb of fluid and then deliver a therapeutic agent, without having to withdraw the inner cannula from the subretinal space between the acts of delivering the leading bleb delivering the therapeutic agent.
DEVICE FOR OCULAR ADMINISTRATION OF FLUIDS
Device for administering a fluid into a patient's conjunctival sac, which combines in a single product optimum characteristics in terms of stability, positioning and spacing of the fluid dispenser with respect to the surface of the eye, as well as guiding of the dispensed fluid towards the center of the eye. The device has the shape of a hollow truncated cone, the minor (top) base of which is adapted to house the dripper of a fluid dispenser and the major (bottom) base of which has a non-coplanar ovoid shape and is adapted to rest precisely on the periocular area. The device allows safe spacing of the tip of the dripper from the corneal surface, preventing accidental contact between dripper and cornea. The dispensed fluid is directed towards the center of the eye surface, without coming into contact with the device. The device is constructively simple, low-cost and suitable for possible disposable use.
DELIVERING OCULAR IMPLANTS INTO THE EYE
A method of deploying an ocular implant into Schlemm's canal of an eye. The method includes the steps of inserting a distal end of a cannula through a cornea of the eye and into an anterior chamber of the eye, the cannula having a distal opening extending from the distal end and through a side wall; placing the distal opening of the cannula into fluid communication with Schlemm's canal; advancing the ocular implant distally through the cannula with a delivery tool engaged with the ocular implant, a proximal portion of the ocular implant engaging the delivery tool proximal to a distal portion of the delivery tool; and disengaging the ocular implant and the delivery tool when the proximal portion of the ocular implant reaches the cannula distal opening. The invention also includes a system for practicing the method.
GUIDE APPARATUS FOR TANGENTIAL ENTRY INTO SUPRACHOROIDAL SPACE
An apparatus includes a body and a pair of rigid legs extending from the body. The body includes an engagement feature configured to engage a deployment instrument. The legs are parallel with each other. Each leg has a sharp tip. The legs both extend along a plane. The body defines a guide opening. The guide opening is oriented transversely relative to the plane associated with the legs. The guide opening is sized to receive a cannula having a generally flat profile. The guide opening is configured to guide the cannula through a sclerotomy at a substantially tangential orientation.
NOZZLE FOR A FLUID DELIVERY DEVICE
A non-gravitational fluid delivery device is provided for delivering fluid to an eye of a user. The device has a cartridge including a container and a cartridge head coupled to the container. The container defines an inner container chamber configured to accommodate a fluid. The head includes opposing first and second walls collectively defining both a nozzle and a nozzle opening extending through the nozzle. The first wall is at least partially formed from a deformable material. The second wall is at least partially formed from a rigid material. Fluid is selectively delivered from the fluid delivery device to the eye through the nozzle opening. The nozzle opening extends in a fluid delivery direction between the first and second walls. The nozzle opening is selectively transitioned between opened and closed conditions via selective manipulation of the first wall.
STERILIZABLE PRE-FILLED PHARMACEUTICAL PACKAGES COMPRISING A LIQUID FORMULATION OF A VEGF-ANTAGONIST
A pre-filled pharmaceutical package comprising a liquid formulation of a VEGF-antagonist, for example Ranibizumab, inside the package. A nonlimiting example of the package can be a syringe, cartridge, or vial, made in part or in whole of a thermoplastic polymer, coated on the interior with a tie coating or layer, a barrier coating or layer, a pH protective coating or layer, and optionally a lubricity coating or layer. Optionally, the package further comprises a bag, a blister, a pouch or any other vessel. Stability performance of the VEGF-antagonist packaged in the coated COP vessel comparable to or better than glass was obtained. The said pre-filled pharmaceutical package comprising a liquid formulation of a VEGF-antagonist is suitable for sterilization (such as for surface and/or terminal sterilization) with sterilization gas residuals being minimal and/or lower than required by ISO 10993-7.
Eye drop applicator
An eye drop applicator includes an applicator body with a top cavity, a bottom cavity, and a dispensing channel connecting the bottom cavity with the top cavity such that a fluid can selectively flow through the dispensing channel to the top cavity. The top cavity includes an opening at a top end of the applicator body, and the bottom cavity includes a bottom opening at a bottom end of the applicator body. The bottom cavity may receive a portion of an applicator container within the bottom cavity to assemble the eye drop applicator with the applicator container containing the fluid to be dispensed.
Automated Eye Drop Dispenser
An apparatus for dispensing eyedrops comprising: a mechanism provided for controllably delivering a predetermined quantity of liquid; and an opaque eye cup provided for at least partially retracting the eyelids of a user's eye when applied around said user's eye; said eye cup having a distal aperture and being coupled to said mechanism such that said predetermined quantity of liquid drops through said distal aperture into a portion of the eye exposed by said at least partially retracted eyelids when said portion of the eye is maintained vertically aligned under said distal aperture.
Delivering ocular implants into the eye
A method of deploying an ocular implant into Schlemm's canal of an eye. The method includes the steps of inserting a distal end of a cannula through a cornea of the eye and into an anterior chamber of the eye, the cannula having a distal opening extending from the distal end and through a side wall; placing the distal opening of the cannula into fluid communication with Schlemm's canal; advancing the ocular implant distally through the cannula with a delivery tool engaged with the ocular implant, a proximal portion of the ocular implant engaging the delivery tool proximal to a distal portion of the delivery tool; and disengaging the ocular implant and the delivery tool when the proximal portion of the ocular implant reaches the cannula distal opening. The invention also includes a system for practicing the method.
