EPICARDIAL LEAD PLACEMENT APPARATUS, SYSTEMS, AND METHODS

摘要

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.

主权项

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.
