Remote pericardial hemostasis for ventricular access and reconstruction or other organ therapies

摘要

Embodiments described herein provide devices, systems, and methods that reduce the distance between two locations in tissue, often for treatment of congestive heart failure. For example, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular septum. The anchor may be deployed into the heart through a working lumen of a minimally invasive access tool. The minimally invasive access tool may have a plurality of grippers near a distal end of the working lumen. The grippers may engage epicardial tissue of the heart and may be moved radially inwardly relative so as to provide stabilization of the epicardial tissue and/or hemostasis near an access site where the anchor is inserted through the epicardium. The minimally invasive access tool may minimize blood loss from the access site and improve anchor implant processes.

主权项

1. A system for engaging epicardial tissue of a patient's heart, the system comprising:
an elongate tool body having a proximal end and a distal end, the elongate tool body being insertable through a body wall of the patient and the elongate tool body having a lumen that is fluidly coupled with a vacuum source positioned external to the patient; and a gripping device near the distal end of the elongate tool body and operable therewith, the gripping device being disposed radially outwardly of the lumen and being configured to be releasably attached to the epicardial tissue of the heart around an access site of an intracardiac device that is configured to perform a medical procedure within a chamber of the heart; wherein the gripping device is coupled with an actuator that is articulatable from outside the patient body so as to move the gripping device radially inwardly toward an axis of the intracardiac device so as to facilitate stabilizing or hemostasis of the heart about the intracardiac device; and wherein the gripping device comprises a suction device having an arcuate suction channel, the arcuate suction channel having a plurality of suction ports positioned on a bottom surface that are configured to contact the epicardial tissue, the suction ports being configured to releasably attach the gripping device to the epicardial tissue via suction through the suction ports, and wherein the arcuate suction channel comprises an aperture shaped and sized to receivably couple with an outer surface of the intracardiac device, wherein said aperture is surrounded by the plurality of suction ports.
