Access System
First Claim
1. An access system for a device, comprising:
- a member including a semispherical surface defining an aperture;
a hub defining an aperture and being slideably coupled to the member by a guide;
a lock mechanism configured to lock the hub relative to the member on the guide;
a removable probe that is inserted through the hub and the member; and
a magnetically trackable sensor;
wherein the member is positioned against a surface; and
wherein the hub is slid relative to the plate along the guide until the sensor indicates that the probe is positioned at a target site.

Abstract
Systems and methods for providing access to a target site. Example systems can include a needle and a grid to guide the needle. One system includes 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 can also include a lock mechanism configured to lock the hub relative to the plate on the guide, and a needle coupled to the hub, the needle including a magnetically trackable sensor positioned in a tip of the needle. The semispherical surface of the member 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 the lock mechanism when the tip of the needle reaches the target site, and an ablation agent is delivered to the target site through the needle, or a tissue sample is obtained.

9. An access system for an ablation device, comprising:
-
a plate defining an aperture;
a member coupled to the plate and defining a semispherical surface;
a hub slideably coupled to the plate by a rod;
a lock mechanism configured to lock the hub relative to the plate on the rod; and
a needle coupled to the hub, the needle including a magnetically trackable coil positioned in a tip of the needle;
wherein the semispherical surface of the member is positioned against skin of a body, wherein the hub is slid relative to the plate along the rod to insert the needle through the aperture in the plate into the body until the tip reaches a target site, wherein the hub is locked by the lock mechanism when the tip of the needle reaches the target site, and wherein an ablation agent is delivered to the target site through the needle, or a tissue sample is obtained. - View Dependent Claims (10, 11, 12)

13. A method of providing access to a target site in a body, the method comprising:
-
positioning a button including a semispherical surface against the body;
sliding a hub relative to a stabilizing plate to introduce a needle into the body;
magnetically tracking a tip of the needle as it moves through the body;
locking the hub relative to the stabilizing plate when the needle reaches the target site; and
introducing an ablation agent to the target site through the needle, or obtaining a tissue sample at the target site. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
