Dosage Delivery in Miniature Dispensing Pumps
20170367882 · 2017-12-28 ·

A meniscus compensating device for a low dosage fluid dispenser, the dispenser having a pump that is fluidly connectable between a pump outlet and a nozzle portion of the dispenser. The pump is operable to dispense a predetermined dose of the fluid through the pump outlet toward the nozzle portion. The meniscus compensating device has a fluid displacer, operable to displace a predetermined volume provided within the fluid column defined between the pump outlet and the nozzle mouth of the nozzle portion and the fluid displacer displaces the predetermined volume during dispensation of a releasing dose from the dispenser pump. The fluid displacer is at least partially released as or after the pump outlet is closed following the dose dispensation, thereby enabling the fluid column defined between the pump outlet and the nozzle mouth of the nozzle portion to occupy the previous displaced predetermined volume, thereby causing the meniscus formed after the dose dispensation at the terminal end of the fluid column at or near the nozzle mouth to come to rest at a substantively consistent predetermined position at or within the nozzle mouth.

DELIVERY SYSTEM FOR PERCUTANEOUS DELIVERY AND IMPLANTATION OF ATRIOVENTRICULAR HEART VALVES
20170360557 · 2017-12-21 ·

Described is a delivery system for percutaneous delivery and implantation of a heart valve. The delivery system includes a handle with a sheath extending therefrom. A splay shaft extends from the handle through the sheath. At least two arms extend from the handle through the splay shaft. The at least two arms are operable for holding a heart valve. A sheath controller is housed within the handle and is operable for selectively advancing or retracting the sheath to constrain or expose a heart valve as attached with the at least two arms. A splay shaft controller is housed within the handle for allowing the user to selectively advance or retract the splay shaft to constrain or expose the at least two arms. Finally, a valve release is attached with the handle to allow a user to selectively release a heart valve as attached with the at least two arms.

OCULAR IMPLANT DELIVERY DEVICE AND METHOD

An ocular implant system including an ocular implant sized and shaped to be inserted at least partially into an eye; a carrier member with a shell having a central channel extending at least partially through the shell from a proximal end towards a distal end of the shell. A guide sleeve removably attached within at least a first region of the central channel of the shell and defining a proximal port into the central channel that is accessible from the proximal end of the shell. An implant holder removably attached within at least a second region of the central channel of the shell adjacent to a distal end of the guide sleeve and having a pair of graspers adapted to releasably secure the implant at a distal end of the implant holder. Related devices, systems, and/or methods are described.

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.

Multi-dose ocular fluid delivery system

Multi-dose ocular fluid delivery devices are provided. Aspects of the fluid delivery devices include a fluid package and an actuator. The fluid package includes a reservoir of an ophthalmic formulation, an aperture and a valve member for sealing the aperture when fluid is not being ejected therethrough. The actuator is configured to operate the valve member so as to at least reduce, if not prevent, ingress of outside materials or contaminants into the reservoir, such that the ophthalmic formulation present in the reservoir does not require a preservative (e.g., where a preservative-free ophthalmic formulation is present in the reservoir). Also provided are methods of using the devices in fluid delivery applications, as well as a kit that includes components of the devices.

Limited step methods and apparatus for medicine sterilizing and bottling

Methods and apparatus for sterilizing and filling vessels which are kept in a sterile environment while being filled are capped before filling and immediately thereafter are ready to be displaced into a potentially contaminating environment while retaining a predetermined SAL are disclosed. Such vessels can be syringes use for dispensing Avastin or conventional syringes. Also method and apparatus for making an eye drop bottle using a conventional medical syringe which can be used in kits made according to the present invention are disclosed. In addition, a method for modifying conventional eye drop bottles for use in kits made according to the instant invention is disclosed. Further, a method for linking single convenience kits to form increased numbers of vessels filled by the same single act, used to fill a single convenience kit, is also disclosed.

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.

MEDICAMENT DISPENSER
20170333250 · 2017-11-23 ·

A dispenser comprises a cylinder in fluid communication with a one-way valve and an inlet in fluid communication with the cylinder. A lumen and a flow control member deliver fluid from a container to the inlet. A piston draws fluid through the flow control member and inlet into the cylinder upon movement of the piston in a first direction, and expels the fluid through the one-way valve upon movement of the piston in a second direction. The dispenser may be activated by either a “dual-action” mode of operation where an activating member is moved to retract the piston and provide the stored energy and then an-actuator is depressed to release the stored energy to the piston or a “single-action” mode of operation where an actuator is depressed in a single direction which concurrently retracts the piston, provides the stored energy and then releases the stored energy to piston.
