Abstract
The invention provides systems and methods for providing access to a target site. Example systems may include a needle, a grid to guide the needle, a plate with an aperture, a member coupled to the plate and including a semispherical surface, and a hub slideably coupled to the plate by a guide. The system may also include a needle coupled to the hub, the needle including a magnetically trackable sensor positioned in a tip of the needle. The semispherical surface can be positioned against skin of a body and the hub slid relative to the plate along the guide to insert the needle through the aperture in the plate into the body until the tip reaches a target site. The hub can be locked by a lock mechanism when the tip of the needle reaches the target site, and an action performed on the target site through the needle.
