System and method for lead implantation in a pericardial space

Abstract

A system for pericardial lead implantation is disclosed herein. The system includes an implantation tool and a stimulation lead. The implantation tool includes a tubular body, a first lumen, a second lumen, a stylet or guidewire, a first port, and a second port. The first and second lumens longitudinally extend through tubular body. The first port is in communication with the first lumen, and the second port is in communication with the second lumen. The stylet or guidewire is longitudinally displaceable in the first lumen and across the first port. A tissue adhesive is selectively administrable through the second port via the second lumen. The stimulation lead includes a distal end and an engagement feature. Placing the engagement feature in the first port and causing the stylet or guidewire to displace in a first direction across the first port causes the lead to attach to the implantation tool. Displacing the stylet or guidewire in a second direction opposite the first direction allows the lead to detach from the implantation tool.
