    Abstract: Embodiments described herein relate to methods and apparatus for extracting a fluid from a container. In some aspects, an extraction member can comprise a first coupling portion configured to removably couple the extraction member to a medicament container containing a medicament, a puncture member defining a fluidic channel and configured to pierce the septum seal to establish fluidic communication between the medicament container and the medicament injector, and a seal disposed between the first coupling portion and the second coupling portion, and defining an opening through which the puncture member is disposed and extends therefrom towards the first coupling portion thereby defining a medicament collection area circumferentially surrounding a portion of the puncture member between the seal and a distal end of the puncture member.

    Abstract: An apparatus includes a housing, an adjustment member, and a microneedle. The housing can be coupled to a medicament container, and includes a hub surface that can contact a target surface. The adjustment member is within the housing and separates an inner volume of the housing into a first chamber and a second chamber. The first chamber is fluidically coupled with the medicament container. The adjustment member, which is coupled to the microneedle, can transition between a first configuration and a second configuration. A proximal end portion of the microneedle is fluidically coupled to the first chamber such that a substance can be conveyed from the medicament container through the microneedle. A distal tip of the microneedle extends from the hub surface by a first distance when the adjustment member is in the first configuration, and by a second distance when the adjustment member is in the second configuration.

    Abstract: Embodiments described herein relate to systems and methods of retinal injection. In some aspects, a method includes inserting a distal end portion of a hollow conduit of a medical injector into an eye of a patient until the distal end portion reaches a reference location, the medical injector having a housing from which the hollow conduit distally extends and confirming disposal of the distal end portion of the hollow conduit in the reference location. After the confirming, the method further includes extending the distal end portion of the hollow conduit distally relative to the housing and from the reference location such that the distal end portion enters an injection region of the eye. With the distal end portion of the hollow conduit disposed in the injection region of the eye, medicament is conveyed into the injection region via the hollow conduit.
