Abstract: A system for delivering a medication in a liquid suspension, powder or gel through an epidermis of a patient. The system includes: a) a plurality of microneedles which are dissolvable and configured for insertion into a dermis of the patient and delivery into the dermis and/or even further layers of the patient's skin, wherein the plurality of microneedles include: i) one or more neurotoxins and/or one or more dermal fillers; ii) one or more carriers; iii) optionally, one or more local anesthetics; b) one or more substrates configured to be temporarily applied onto the epidermis of the patient, wherein the one or more substrates carry the plurality of microneedles thereon; c) optionally, one or more trays affixed to the one or more substrates, wherein the one or more trays include one or more adhesive patches; and d) optionally, one or more removable covers.

Abstract: A device, comprising: a tubular member which is flexible, the tubular member forming a channel when in an open and active configuration and the tubular member narrowed when in a closed and inactive configuration. The device, once expanded into the open and active configuration provides for a channel. The channel provides for a passthrough for medical instruments.

Abstract: A dilator includes a tubular member composed of a flexible material, the tubular member forming a channel; wires extending inwardly from an interior of the tubular member into the channel; a string attached to the wires and extending through the channel; and a handle attached to the string; pulling the handle applies force to the string; force to the string causes the string to disengage from the wires such that the wires recoil against the interior of the tubular member such that the tubular member takes on a diameter of a predetermined dimension; and the tubular member in a recoiled state provides for dilation of a canal.
