An implantation device having a reservoir for holding a solid or semisolid implant and a carrier fluid, wherein the reservoir includes a cannula. The cannula has a tip end and a delivery opening therein both shaped and dimensioned to suit the application. For example, an implant (such as a retinal cell graft) and suitable carrier fluid (such as an aqueous hyaluronic acid solution) can be expressed from the opening into the subretinal space of a recipient eye, provided the cannula is of sufficient length that the tip end can reach the subretinal space while the remainder of the fluid reservoir is external of the eye. Expression of the carrier fluid from the reservoir via the delivery opening expels the implant through the delivery opening. An electromechanically driven plunger apparatus with operator controls is provided in a preferred embodiment.
An implantation device for implanting a solid or semisolid implant into a mammal or human, comprising:
A method for subretinal or epiretinal implantation of a solid or semisolid implant into a mammal or human eye, comprising the steps of
A system for implanting solid or semisolid implants into a mammal or human, comprising:
