An ocular medical injector is provided for drug delivery. A method includes inserting a puncture member of the medical injector into the eye until the puncture member reaches the SCS. The puncture member defines a lumen therethrough. With the puncture member disposed within the SCS, a flexible cannula is advanced distally through the lumen of the puncture member, beyond the distal end portion of the puncture member and along the SCS towards a posterior region of the eye. The flexible cannula has an atraumatic distal tip and defines a lumen therethrough. With the distal tip of the flexible cannula disposed within the SCS beyond a distal end portion of the puncture member, a therapeutic substance is administered to the SCS.

An ophthalmic device including a cannula having a cannula distal end, a lumen, and one or more orifices coupled to the lumen is provided. The cannula is configured to deliver a fluid. A sleeve is disposed around the cannula and has a sleeve distal end. A handle is coupled to the sleeve and the cannula, the handle having an actuator. An internal mechanism is coupled to the actuator and is configured to pump the fluid. The internal mechanism includes an inlet port disposed on a handle proximal end, a drive member coupled to the actuator and a plunger coupled to the drive member. The ophthalmic device is configured to retain a volume of fluid and to be prevented from being re-primed after a predetermined number of actuator presses, wherein the retained volume of fluid is dispensed over an additional number of actuator pushes.

An apparatus and its method of use for the treatment of patients by the delivery of a temperature-controlled material. The apparatus and its method of use can be performed in conjunction with endoscopic ultrasound interventional procedures such as tumor imaging or biopsy. The apparatus can be integrated with the working channel of endoscopic ultrasound devices or other imaging devices (bronchoscope, colonoscope) or can operate as a stand-alone apparatus.

The present disclosure relates to a medicament container for accommodating a liquid medicament. The medicament container includes an elongated container barrel defining a longitudinal direction and having a proximal end and a distal end. The proximal end is opposite the distal end. The container barrel includes a proximal container cross section at the proximal end. The elongated container barrel includes a distal container cross section at the distal end and the proximal container cross section is substantially identical to the distal container cross section. The medicament container further includes a seal arranged at the distal end and extending across the distal container cross section, and a retainer engaged with the seal and engaged with the elongated container barrel to fix the seal to the distal end.

The present invention concerns an elastomeric stopper (18, 28, 38) for a drug reservoir, comprising: a stopper body (18.1, 28.1, 38.1) extending along a reference axis between a leading end surface (18.2, 28.2, 38.2) and a trailing end surface (18.3, 28.3, 38.3) and having a generally cylindrical sidewall with an outer body diameter, a circumferential convex rib (18.6, 28.6, 38.6) extending radially outwardly from the sidewall, a non-convex trim edge portion (18.7, 28.7, 38.7) at the trailing end surface (18.3, 28.3, 38.3), the non-convex trim edge portion (18.7, 28.7, 38.7) having an outer trim edge diameter which is greater than the outer body diameter and being axially spaced apart from the circumferential convex rib (18.6, 28.6, 38.6), providing an annular recess (18.9, 28.9, 38.9) therebetween. The elastomeric stopper (18, 28, 38) further comprises a channel structure (18.10, 28.10, 38.10) enabling fluid flow from the trailing end surface (18.3, 28.3, 38.3) to the annular recess (18.9, 28.9, 38.9) through the non-convex trim edge portion (18.7, 28.7, 38.7).

Disclosed herein is a valve assembly comprising a male luer end portion and a female luer end portion and a passage for the transfer of fluids extending between the male and female luer end portions, valve means movable between a first position, in which the passage is closed, and a second position, in which the passage is open, biasing means for biasing the valve means toward the first position, and actuating means extending into the male luer end portion and coupled to the valve means to actuate the valve means when a female luer end portion of a medical accessory is engaged with the male luer end portion.

The present invention provides devices to access the suprachoroidal space or sub-retinal space in an eye via a minimally invasive transconjunctival approach. The devices may also be used after a partial dissection, for example after dissection of the outer scleral layer of the eye, and using the device within the dissection to access the suprachoroidal space or the sub-retinal space.

Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.

A needle and pre-filled syringe system that provides ultra-low dosage waste and automatic needlestick protection. A syringe assembly is pre-filled with an injection material. A needle head assembly attaches to the syringe assembly. A spacer is disposed between the needle head assembly and the syringe assembly. The spacer has a central opening. The needle head assembly supports a needle with a needle base. When assembled, the needle base passed into the central opening of the spacer. The needle head assembly also contains a safety slide that can selectively cover the needle. During an injection, pressure and/or contact with the plunger head causes the spacer to contact and move the safety slide. The safety slide moves to cover the needle during the injection procedure, therein rendering the needle safe before the injection process is even complete.
