Abstract:
1. A system for use with a vacuum source for placing a lead into a tissue of a heart, comprising: an engagement catheter comprising a proximal end, a distal end, and first and second lumens extending between the proximal end and the distal end; a delivery catheter comprising an elongated tube having a wall and a first lumen, wherein the delivery catheter is configured such that the delivery catheter is capable of at least partial insertion into the second lumen of the engagement catheter; a lead having a tip at a distal end, the lead configured for at least partial insertion into the first lumen of the delivery catheter; and a vacuum port located at the proximal end of the engagement catheter, the vacuum port being operatively connected to the first lumen of the engagement catheter and capable of operative connection to a vacuum source; wherein the first lumen of the engagement catheter includes a suction port located at or near the distal end of the engagement catheter, the suction port being configured to removably attach to a targeted tissue on an interior of a wall of a heart after the engagement catheter has been advanced through a blood vessel into the heart, such that the suction port is capable of forming a reversible seal with the targeted tissue when the vacuum source is operatively attached to the vacuum port.
