Abstract:
1. A system for engaging heart tissue, the system comprising: an engagement catheter extending from a distal end to a proximal end and defining a first lumen therethrough, the engagement catheter having a suction port at or near the distal end and a vacuum port at or near the proximal end; a delivery catheter comprising an elongated tube extending from a delivery catheter distal end to a delivery catheter proximal end and defining a delivery catheter lumen therethrough, the delivery catheter configured for slidable insertion into the first lumen of the engagement catheter; and an implantable device configured for insertion into the delivery catheter lumen and further configured so that at least part of the implantable device extends from the delivery catheter distal end upon implantation into a patient; wherein the delivery catheter lumen has a bend, relative to the elongated tube, at or near the delivery catheter distal end, and a bend outlet through the elongated tube, so that a portion of the implantable device can be delivered through the delivery catheter lumen, to the bend, and out of the bend outlet; and wherein the suction port is configured to removably attach to a targeted tissue on an interior wall of a heart of the patient after the engagement catheter has been advanced through a blood vessel and into the heart, the suction port forming a reversible seal with the targeted tissue when a vacuum source is operatively coupled to the vacuum port; and wherein the implantable device comprises an elongated shaft with a plug positioned thereon, the plug defining a hole extending from a plug distal end to a plug proximal end, wherein at least part of the elongated shaft is positioned within the hole.
