1. A system for use with a heart having a pericardium, an epicardium, and an endocardium, the system comprising:
- an anchoring assembly that comprises a guidewire and a magnetic anchor, wherein at least a distal portion of the anchoring assembly is sized to be inserted between the pericardium and the epicardium, and wherein the magnetic anchor is configured to magnetically interact with a magnetic guide that is positioned at an interior of the endocardium to hold the anchoring assembly against the epicardium; and
an elongated body that comprises an electrical lead, the elongated body having a proximal end and a distal end, wherein the proximal end is configured to be coupled with an electrical controller, and wherein the elongated body is configured to be selectively coupled with the guidewire to permit the distal end to be advanced distally relative to the guidewire into close proximity to the magnetic anchor when the magnetic anchor is between the pericardium and the epicardium.

Abstract
An anchoring assembly can be used to electrically couple an electrical lead with the heart of a patient. The anchoring assembly can include a guidewire and a magnetic anchor. At least a distal portion of the anchoring assembly can be sized to be inserted between the pericardium and the epicardium, and the magnetic anchor can magnetically interact with a magnetic guide that is positioned at an interior of the endocardium to hold the anchoring assembly against the epicardium.

15. A method of electrically communicating with a heart having an endocardium, an epicardium, and a pericardium, the method comprising:
-
positioning a magnetic guide at an interior of the endocardium; inserting a magnetic anchor that is attached to a guidewire into a space between the pericardium and the epicardium; holding the magnetic anchor against the epicardium at a first position via magnetic interaction between the magnetic guide and the magnetic anchor; advancing an elongated body that comprises an electrical lead along the guidewire and into the space between the pericardium and the epicardium; and electrically coupling the electrical lead with the heart. - View Dependent Claims (16, 17, 18, 19, 21)
