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.

Abstract: An acoustic transducer array and method of making same. A first metal layer is deposited on a first side of a piezoelectric composite to form a common electrode and a second metal layer is provided over the obverse side. Portions of the second metal layer are removed to create a plurality of individual electrodes. A third metal layer may be deposited onto the plurality of individual electrodes, the third metal layer being thicker than the second metal layer. The individual electrodes extend beyond the piezoelectric composite in the elevation direction to create electrode leads. Metal layers may be provided by lithography, a wireframe or a foil sheet.
