A method for gaining access to a vein includes implanting a vein localizer above or adjacent an anterior portion of a vein. The vein localizer features a fluorescent coating which emits visible light upon illumination by an external light. This makes visualization easier for a more confident vessel puncture at the first attempt. The invention is designed to reduce failed venipunctures, improve patient comfort and avoid unnecessary time and expense associated with multiple vein punctures.

The present invention is a Miniature Vein Enhancer, for use in imaging the subcutaneous veins of a target area of a patient by a practitioner. The miniature vein enhancer includes a Miniature Projection Head that is secured to a tourniquet, where the tourniquet may be mounted to the bicep of a patient. The Miniature Projection Head includes a housing, and apparatus that images subcutaneous veins of the target area, and projects the image(s) of the veins onto the target area to overlie the subcutaneous veins, which aids the practitioner in pinpointing a vein location for a venipuncture procedure such as an intravenous drip, blood test, and the like.

An autoinjector device and a method of use thereof for perispinal administration, comprising: a housing with an interspinous stop; a syringe assembly slidably mounted on the housing, the syringe assembly including a needle and a fluid container, an autoinjector actuator for urging the syringe assembly with respect to the housing from a storage position to a launch position wherein the needle travels through the interspinous stop; and a cap releasably engaged to the housing.

A system to measure and display the orientation of a handheld instrument is disclosed.

The present invention discloses a technique for determining a position of a distal end of a probe relative to a blood vessel. The method comprises receiving a first pressure pattern comprising a plurality of pressure values being indicative of a pressure of a fluid when the distal end of the probe is located inside the blood vessel, processing the first pressure pattern, and determining at least one adaptive threshold and/or a tendency indication. The adaptive threshold is indicative of a transition from a first position state to a second position state, or vice versa. The tendency indication is indicative of a certain trend of the pressure pattern. The first position state defines an in-blood vessel condition in which the distal end of the probe is located inside the blood vessel and the second position state defines at least one exit condition in which the distal end of the probe is located at least partially outside the blood vessel.

Injection devices for delivering pharmaceutical compositions into the eye are described. Some devices include a resistance component for controllably deploying an injection needle through the eye wall. The resistance component may be disposed on the injector device, or on a portion of the injection device housing, or on a drug reservoir. Some devices may be removably attached to a drug reservoir, for example, through a luer connector. Other devices may comprise internal luer seal for securely connecting a drug conduit of the device to the luer cavity of a drug reservoir. Yet other devices may comprise a priming-enabling element to facilitate the drug priming of a shielded needle. Related methods and systems comprising the devices are also described.

An apparatus for targeting an injection site using anatomical landmarks includes a first landmark identifier, a second landmark identifier, and a targeting band. The targeting band is connected with the first landmark identifier at a first end and a second landmark identifier at a second end. At least a portion of the targeting band is linearly deformable. In another embodiment, an apparatus for targeting an injection site using anatomical landmarks on a patient includes a targeting band having a first end and a second end, at least a portion of the targeting being linearly deformable, a first landmark identifier pivotably connected to the targeting band at the first end, a second landmark identifier configured to be connected with the second end of the targeting band; and a fastener configured to secure the first and second landmark identifiers to the patient.

A medical device includes a head having a base and a piercing member fluidly connected to the base. The medical device includes a tube having a proximal end, a distal end, a first central channel extending from the proximal end to distal end, and a longitudinal axis extending substantially centrally through the first central channel, the distal end of the tube being removably attached to the base. The medical device includes a plunger slidably disposed partly within the first central channel of the tube, the plunger defining a second central channel, and the longitudinal axis extending substantially centrally through the second central channel. In some examples, the medical device includes an optic assembly having a light source and a light pipe that is disposed partly within the second central channel and being configured to receive radiation emitted by the light source; and direct the radiation through the piercing member.

A device for assisting a subcutaneous injection is disclosed. The device includes features which prevent an unwanted needle stick and assist the gripping of tissue for performing a safe and effective subcutaneous injection.

Devices, kits and methods for determining the site of intramuscular injection in adult and child patients are disclosed. The device includes a top element and two legs that are configured to be fastened in a first position and a second position. When placed in the first position and second position, the device forms a substantially triangular region having a center that corresponds to the site of injection.
