Abstract:
1. A system for engaging heart tissue, comprising: an engagement catheter, comprising: a delivery catheter comprising a proximal end, a distal end, and a hollow tube extending between the proximal end and the distal end, the delivery catheter configured such that the hollow tube is capable of insertion through the vacuum port into the first lumen of the engagement catheter while the reversible seal is maintained under vacuum through the first lumen using the suction port; wherein the engagement catheter is configured for percutaneous intravascular insertion into a patient through a blood vessel of the patient and further configured for advancement to the targeted tissue through the blood vessel; wherein the suction port is configured to removably attach to the targeted tissue after introduction of a portion of the system into the blood vessel; and wherein the engagement catheter is configured so that at least a portion of the engagement catheter can be retracted after percutaneous intravascular insertion, while remaining removably attached to the targeted tissue, due to vacuum from the vacuum source through the first lumen of the engagement catheter and suction engagement from the suction port, so to locally increase a distance between the targeted tissue and a pericardium surrounding the heart.
