20230029443 · 2023-01-26 · ·

A valve comprises a first housing including a first lumen extending therethrough and defining a first disk-facing surface and a second housing including a second lumen extending therethrough and defining a second disk-facing surface, the second housing being mated to the first housing so that the second disk-facing surface faces the first disk-facing surface in combination with a flexible disk gripped between gripping portions of the first and second disk-facing surfaces, the disk including a slit extending therethrough which, when acted upon by a fluid pressure of at least a predetermined threshold level opens to permit fluid flow between the first and second lumens and which, when acted upon by a fluid pressure less than the threshold level remains sealed preventing fluid flow between the first and second lumens and a relief well between opposing portions of the first and second housings radially outside the gripping portions, a width of the relief well exceeding a width of a radially outer portion of the flexible disk so that the radially outer portion of the disk is free to move therewithin.

COUPLER DEVICE FOR VALVE ASSEMBLY FOR USE WITH MEDICAL INFUSION DEVICE
20230022342 · 2023-01-26 ·

A coupler of a valve assembly for coupling a flow control valve to an infusion device. The coupler includes a proximal portion and a distal portion. The proximal portion comprises a plurality of recessed segments configured for receiving the infusion device. The distal portion comprises a valve flange that defines a central cavity for receiving the flow control valve. The valve flange comprises a swage extending radially inward to the central cavity for mechanically engaging a luer lock fitting of the valve assembly.

INFUSION CANNULA

Embodiments disclosed herein relate to an infusion cannula for infusion/venting of fluids to/from the eye to control intraocular pressure. The infusion cannula includes a tubular body with a tubular inlet located at a proximal end of the tubular body and a tubular outlet located at a distal end of the tubular body. The tubular outlet is aligned with a first longitudinal axis and configured to extend through a septum of a valved cannula hub. The infusion cannula includes a retention piece extending from or coupled to the tubular body. The retention piece has an annular body surrounding the tubular body at the distal end of the tubular body and configured to be coupled to the valved cannula hub. An inner surface of the annular body has a profile configured to form a snap fit with an overhang formed along an outer surface of the valved cannula hub.

Anti-free-flow valve

An anti-free-flow valve includes a tube and a membrane. The tube extends from a first end of the tube to a second end of the tube. The tube defines a hollow cavity. The membrane is attached to an interior surface of the tube and extends across the hollow cavity to obstruct fluid flow through the hollow cavity. The membrane is spaced apart from the first and second ends of the tube. The membrane defines a slit therethrough that is configured to transition from a closed state that restricts fluid flow to an open state that permits fluid flow through the slit responsive to compression or expansion of the tube proximate to the membrane.

Medicament delivery device and system
11541178 · 2023-01-03 · ·

A medicament delivery device system for delivery of a medicament from a cartridge (10). The system comprises a first container (11) for storage of a first substance, a second container (12) received in the first container (11) for storage of a second substance, and valve means (68) for closing a distal end of the second container (12). The system further comprises a disposable cassette (102) and a reusable firing unit (200). The cassette (102) has a body (104) for receiving the cartridge (10), and a mixing element (148) for displacing the second substance into the first chamber (16) in a mixing stroke, to mix with the first substance to form the medicament.

Retractable needle catheter delivery apparatus

A catheter insertion system includes a housing extending along a longitudinal axis. A needle extends distally from a distal end of the housing. The needle has a longitudinal passage coaxially aligned with the housing. A catheter has a length and is sized and shaped to be advanced from a retracted position within the longitudinal passage of the needle to an extended position with at least a portion of the catheter length extending beyond a distal tip of the needle. The needle is typically configured to be retracted back into the housing after the catheter has been advanced, thus providing an integrated catheter and catheter insertion apparatus. After needle retraction, the housing may be taped to the patient's skin while the needle remains protected within the housing. A luer on the catheter may then be connected to a fluid or other source in an otherwise conventional manner.
