A needle assembly for an injection device is provided to facilitate delivery of a dermal filler. The assembly includes a cannula and a hub. The hub can be coupled to a syringe. The hub includes an inner bore that has a proximal retention section, a stepped section, and a cannula retention section. The stepped section, the proximal retention section, and the cannula retention section are configured to reduce the dead space within the inner bore for preventing detachment of the hub from the syringe during an injection procedure.

Injection device

An aspiration and injection device is provided that can allow for ergonomic, safe, and precise aspiration of a target site and ejection of a medicament to the target site. The device can include a syringe barrel, a flange extender couplable to the barrel, and plunger that can be engaged by a hand and/or one or more finger of a user to perform aspiration and injection at a target site.

Aspiration and injection device

Devices and methods for inserting an implant into skin or other tissue of a patient can include a hyaluronic thread coupled with an insertion device that can provide a supportive enclosure for the thread as it is injected into a patient's skin or other tissue. The device can include a moveable member and laterally extending portions, a closed distal portion, and an inner cavity so that the thread can be positioned within the inner cavity and extend along the moveable member. The laterally extending portions can move, relative to the thread, to expose the thread. In use, the moveable member is insertable into a patient and at least a portion of the moveable member is configured to move within a patient to expose the thread.

Thread insertion devices

Devices and methods for inserting an implant into skin or other tissue of a patient can include an insertion device that can enclose and support a hyaluronic thread as it is injected into a patient's skin or other tissue. The device can include a cover member, a non-tubular support member, and the thread. The cover member can have a proximal portion, a closed distal portion, and an inner cavity extending from the proximal portion toward the closed distal portion. The thread can be positioned along a longitudinal length of support member, between the support member and the cover member. The non-tubular support member can extend within the inner cavity of the cover member. The cover member can be moveable relative to the support member to expose the thread.

Skin can be treated by piercing skin with a plurality of needles of an injection device and ejecting a dose of fluid therethrough. The device can include a housing, a plunger disposed in the housing, a cartridge disposed in the housing, and one or more dosing chambers. The plurality of needles can be coupled to the housing and be in fluid communication with the cartridge. Advancement of the plunger can cause a dose of fluid to be ejected from the plurality of needles.

Devices for injection and dosing

Devices and methods for inserting an implant into skin or other tissue of a patient can include an insertion device having moveable portions that can retain, move, or otherwise control engagement and injection of a hyaluronic thread. The device can include a tubular member and a handle. The handle can include a body component coupled to the tubular member. The body component can include a passage that extends in communication with the lumen. The handle can further comprise first and second arms coupled to the body component and extending outwardly from the distal portion of the tubular member. Based on the configuration, the first and second arms can be positioned along the passage to change a cross-sectional profile of the passage and permit the device to engage or disengage the thread.

Devices and methods for inserting an implant into skin or other tissue of a patient can include a hyaluronic thread that is coupled at along distal portion with an insertion device. The insertion device can include a cover member and a piston that can collectively facilitate engagement with or disengagement of the distal portion of the thread with the device. For example, the piston can be positioned within an inner cavity of the cover member, and the distal portion of the thread can be engaged by and/or between the piston and the cover member. The thread can be released by movement of the piston relative to the cover member. Thus, some insertion devices can grasp or engage the distal portion of the thread and 'push' the distal portion thread into and through into skin or other tissue of a patient.

A needle injection array can comprise a plurality of needles that are fluidly interconnected via a fluid manifold. The fluid manifold can be configured to direct fluid from a syringe to arrive at tips of the needles approximately simultaneously. The fluid manifold also be configured to provide approximately equal dosage or fluid volume through each of the needles to an injection site.

Needle array device

Devices and methods for inserting an implant into skin or other tissue of a patient can include a hyaluronic thread coupled with an insertion device that can provide a supportive enclosure for the thread as it is injected into a patient's skin or other tissue. The device can include a cover member, a base, and a thread. The cover member can have a proximal portion, a closed distal portion, and an inner cavity extending from the proximal portion toward the closed distal portion. The thread can be positioned within the inner cavity and extend from the base toward the closed distal portion. The base can be removably coupled to the proximal portion of the cover member. In use, the cover member is insertable into a patient and separable from the base to expose the thread.
