MECHANISM FOR SETTING A MAXIMUM DOSE OF A MEDICAMENT FOR A VARIABLE DOSE DRUG DELIVERY DEVICE

The present disclosure concerns a mechanism for setting a dose of a medicament for a variable dose drug delivery device, comprising: a housing, a sleeve component configured to rotate relative to the housing during a dose setting operation, and a stop member which is configured to limit a total amount of possible rotation of the sleeve component to a maximum and, thereby, to limit a maximum settable dose, wherein the stop member is configured to allow varying the maximum which determines the total amount of possible rotation of the sleeve component.

APPARATUS FOR SUBRETINAL ADMINISTRATION OF THERAPEUTIC AGENT VIA A CURVED NEEDLE

An apparatus includes a body, a cannula, and a needle. The cannula is flexible and extends distally from the body. The needle is slidably disposed in the cannula. The needle includes a sharp distal tip and a curved portion. The needle is configured to translate relative to the cannula between a proximal position and a distal position. The distal tip is configured to be positioned inside the cannula when the needle is in the proximal position. The distal tip is configured to be positioned outside the cannula when the needle is in the distal position. The needle is resiliently biased to extend along a curve through the curved portion.

Short-bevel non-coring needle

A non-coring needle for use in accessing an implanted medical device is disclosed. The non-coring needle is configured so as to include a compact bevel face relative to standard non-coring needles. In one embodiment, the non-coring needle comprises a hollow cannula that defines a lumen and terminates at a sharpened distal tip. The cannula includes a proximal portion and a bent distal portion. The distal portion defines a bevel face extending proximally from the distal tip, and the bevel face includes the lumen distal opening. The bevel face defines an open angle of at least about one degree with respect to a longitudinal axis of the proximal portion of the cannula. The bevel face is also laterally offset from the proximal portion of the cannula by an offset distance of no more than about 0.010 inch. A portion of the bevel face is dulled to prevent access port septum coring.

The present disclosure relates to a drug delivery device. The drug delivery device comprises a drug container containing a drug liquid, wherein the drug liquid includes insulin glargine dissolved therein, and a hollow needle defining an elongated interior space through which the drug liquid is dispensable from the drug container, wherein the needle is at least partially made of a steel resistant to chloride, wherein the elongated interior space is in fluid communication with the drug container in a storage or pre-delivery condition, for example within a timeframe of at least 1 hour in absence of significant exchange of drug liquid inside the interior space.

PUNCTURE NEEDLE, PUNCTURE NEEDLE KIT, AND STEREOTACTIC BRAIN SURGERY DEVICE
20220233767 · 2022-07-28 ·

The objective of the present invention is for an object discharged from a discharge port to be less liable to form a jet flow, and less liable to cause injury to the central nervous system. A passage 11 for a cell is formed inside a needle body 10 of a puncture needle 1. A discharge port 15 for a cell is formed in a side surface 13b of a front end part 13 of the needle body 10. Furthermore, the needle body is a single tube provided with a passage for an object. Further, a discharge path 14 for a cell, oriented upward from the passage 11 toward the discharge port 15, is formed in the front end part 13. The discharge path 14 comprises a frustoconical part 14a and a columnar part 14b. As a result, the discharge path 14 is formed in such a manner that the surface area of a cross section orthogonal to the upward/downward direction increases smoothly towards the discharge port 15 in at least one part of the discharge path 14, and, in each position in the upward/downward direction, is equal to or greater than the surface area of a cross section in a position closer to the passage 11.
