The injection needle assembly is slidably mounted on the needle of the epidural needle assembly between extended and retracted positions. The injection needle assembly includes an injection hub having an injection needle secured thereto which extends forwardly therefrom. When the injection needle assembly is in its retracted position, the forward end of the injection needle is positioned rearwardly of the forward end of the epidural needle. When the injection needle assembly is in its extended position, the forward end of the injection needle is positioned forwardly of the forward end of the epidural needle. When in its extended position, the injection needle is able to create a hole in the skin of a person or animal to permit the epidural needle to be inserted therein.

A carrier assembly and related sterile kits are disclosed. The carrier assembly is configured to be used with a sensor assembly for determining a characteristic of a human body. The carrier assembly comprises a frame member comprising a sidewall defining a central opening configured to receive at least a portion of the sensor assembly and laterally extending wing members hingedly attached at a proximal end thereof to the sidewall of the frame member. The laterally extending wing members each comprise a cavity proximate a distal end thereof and configured to receive a magnet. Related kits and systems are also disclosed.

A vaccination device can be used to vaccinate day-old chicks. To vaccinate the day-old chicks safely while ensuring vaccination efficacy, the vaccination device can include a vaccination needle configured to extend from the vaccination device at a vaccination delivery location and an action plate. The action plate can be coupled to the vaccination device such that the action plate is positioned next to the vaccination delivery location. The action plate can include an action button, wherein the action button is configured to receive a day-old chick presented to the action plate in a predetermined loading position, receive a press of the action button, and in response to pressing the action button, cause the vaccination needle to extend from the vaccination device at the vaccination delivery location to deliver a subcutaneous injection to the day-old chick.

According to the invention, an injection device (D) comprises a pre-filled syringe and a safety device. The pre-filled syringe comprises a barrel with an inner cavity in fluid communication with a hypodermic needle attached to a distal end of the pre-filled syringe and a piston fluid-tightly sealing a proximal end of the inner cavity. The safety device comprises a support body for retaining the pre-filled syringe therein, an outer body operably connected to the piston, a needle shield and a releasable retaining means (R). The retaining means comprises a radial projection and a longitudinal recess adapted to receive the radial projection. The radial projection is connected to or integral part of one of the support body or the outer body and a longitudinal recess formed into the other of the support body or the outer body. The needle shield, the support body and the outer body are telescopable relative to each other. The piston is movable in a distal direction to expel a medicament contained in the inner cavity through the hypodermic needle by a manual actuation of the outer body. A telescoping movement of the outer body with respect to the support body is restricted by the retaining means (R) when the needle shield is moved with respect to the support body in a proximal direction from an initial position (I) towards a retracted position (II). The retaining means (R) is released when the needle shield reaches the retracted position (II) allowing for a telescoping movement of the outer body with respect to the support body to expel the medicament contained in the pre-filled syringe through the hypodermic needle.

A needle guide assembly for inserting a needle into the body of a patient in order to access a subcutaneous target, such as a vessel, is disclosed. In one embodiment, the needle guide assembly comprises a needle guide body that is configured to at least indirectly and removably attach to an image producing device, such as an ultrasound probe. The needle guide body defines at least first and second elongate guide channels. Each guide channel defines a unique insertion angle with respect to a longitudinal axis of the ultrasound probe. Further, each guide channel is configured to accept needles of differing gauges. In other embodiments other needle guide assemblies are disclosed that include multiple guide channels for inserting a needle at a variety of insertion angles into the patient's body. Related methods are also disclosed. In yet other embodiments, needle guide assemblies including needle stop features are disclosed.

Various handheld medical dispensing configurations and methods including the following: Handheld medical dispensing system comprises a syringe, which has a plunger, releasably mounted to syringe actuation apparatus, the apparatus having an actuator configured such that it can move the plunger more than once to dispense a plurality of amounts of substance from the syringe. A method of dispensing fluid from a syringe comprises holding a medical substance delivery system including a syringe, which has a needle, and which is secured to syringe actuation apparatus configured to dispense predetermined amounts of the substance from the syringe, penetrating the needle at one patient site and using the apparatus to deliver a predetermined amount of the substance, and penetrating the needle at another patient site and using the apparatus to deliver a predetermined amount of the substance.

Systems and methods for mitigating the formation of heterotopic ossification lesions by delivering a neuromuscular inhibitor employ a delivery device to distribute injection of the neuromuscular inhibitor. A delivery device for delivering the neuromuscular inhibitor can include an injector body, a device body for spacing the injector body from a target delivery location, and a plurality of needles; or can include an injector guide having multiple guide holes and an injector needle for delivering the neuromuscular inhibitor via the guide holes.

Method and surgical instrument for treating prostate tissue including a surgical instrument having a main body, a needle deployment port, a needle, first and second handles and a lockout release mechanism to limit needle extension. Additionally, a kit includes the surgical instrument, together with a cystoscope, and optionally a syringe and reservoir of ethanol. The method includes needle-less injection and visualizing the ethanol injection by delivering both an echogenic agent and ethanol either by needle or needle-less injection or by providing an ultrasonically visible marker near the tip of the ethanol delivery cannula. The method also includes extending the needle transversely of the instrument housing using a link assembly.

A method of manufacturing an autoinjector includes supplying a preloaded syringe including a sterile needle and a needle cover, a preassembled distal housing portion including an adhesive base on a distal end thereof and a channel for insertion of the preloaded syringe, and a proximal housing portion including a motor and a transmission.
