ELECTRODE INSERTION TOOLS, LEAD ASSEMBLIES, KITS AND METHODS FOR PLACEMENT OF CARDIAC DEVICE ELECTRODES

摘要

Insertion tools, lead assemblies, kits, and methods for placement of cardiac device electrodes. In some embodiments, an insertion tool having a proximal end and a distal, dissecting end includes a structure configured to receive or engage a structure on a lead assembly. Some embodiments include a lead assembly having an end including a structure configured for engaging the distal end of an associated insertion tool. Some embodiments include kits or systems including both an insertion tool and a lead assembly, each having a structure for engaging the other. In these embodiments, the engaging structures may take several forms including threads, small posts, circular or semi-circular receiving members, and/or a slot. Some embodiments also include methods for placement of cardiac device electrodes with the assistance of an associated insertion tool, wherein the cardiac device electrodes are associated with a lead assembly having an end configured to engage a distal, dissecting portion of an associated insertion tool.

主权项

1. A tool for use in subcutaneous insertion of a lead electrode assembly, the tool comprising:
a proximal end having a handle; a distal end including a dissecting tip shaped for separating subcutaneous tissue to form a channel therethrough, and an engaging structure disposed adjacent to the dissecting tip; and a shaft extending between the proximal and distal ends; wherein the engaging structure is configured to directly engage a portion of an associated lead assembly.
