Injection Devices for Unimpeded Target Location Testing
First Claim
1. An injection device for injecting an implant into a body at a target location at which the implant will function effectively comprising:
- a. a probe device comprising;
i. an elongated probe having a distal end and a proximal end;
ii. a probe handle;
b. a cannula device comprising;
i. an elongated cannula having a cannula lumen, a sharp beveled tip at the distal end of the elongated cannula, and a plurality of channels formed through the cannula lumen, wherein the elongated cannula is configured to slide onto the elongated probe; and
ii. a cannula handle having a peg, configured to slide into the probe handle;
and c. an implant having at least one implant external electrode, configured to be releasably held within the cannula lumen;
wherein the elongated cannula is configured to pierce the body via the distal end sharp beveled tip while the implant is held within the cannula lumen.

Abstract
Devices and methods for positioning an implant at a target location in the body. The methods include testing an implant while within an injection device at a target location to determine whether the implant is functioning effectively. The methods also include testing from or delivery of materials to the target location during implantation, and loading the injection device for use. The device may be configured to permit the longitudinal and/or axial position of the implant to be maintained relative to an injection device during implantation. The device may also be configured to permit testing of the implant. Implants configured for use in the injection devices may also be included.
