Leadless cardiac stimulation systems
First Claim
1. A catheter delivery system for implantation of at least a portion of a wireless electrode assembly through endocardium tissue and into myocardium tissue, comprising:
- a first elongate member having a proximal end and a distal end and defining a lumen passing therethrough;
a second elongate member having a proximal end and a distal end; and
a wireless electrode assembly attachable to the distal end of the second elongate member, wherein when the electrode assembly is attached to the second elongate member, the second elongate member is passable through the lumen to deliver at least a portion of the electrode assembly through the endocardium and into the myocardium.

Abstract
Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrode assemblies that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Also disclosed are various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.

15. An implantable wireless electrode assembly comprising:
-
a first electrode to discharge a pacing electrical pulse; and
an attachment mechanism having at least one fastener to penetrate through endocardium tissue and into myocardium tissue, at least a portion of the attachment mechanism being disposed proximate to the electrode such that, when the fastener penetrates through the endocardium and into the myocardium, the electrode is positioned proximate to the myocardium. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A method of delivering a wireless electrode assembly into an internal heart chamber and proximate the myocardium, the method comprising:
-
directing a distal end of a first elongate member into an internal heart chamber, the first elongate member having the distal end and a proximal end and having a lumen passing therethrough;
directing a wireless electrode assembly through the lumen of the first elongate member toward the distal end of the first elongate member; and
penetrating at least a portion of the wireless electrode assembly through endocardium tissue and into the myocardium. - View Dependent Claims (25, 26, 27, 28, 29, 30)
