Devices, systems, and methods for myocardial infarct border zone reinforcement

A suction/infusion catheter for facilitating myocardial infarct border zone reinforcement, comprising:

• one or more apertures defined along a portion of a suction/infusion catheter at or near a distal end of the suction/infusion catheter;
• a first configuration when the suction/infusion catheter is at least partially extended from a delivery catheter;
• and
• a second configuration when the suction/infusion catheter is positioned within the delivery catheter, the second configuration different from the first configuration;
• wherein the suction/infusion catheter, when introduced into a pericardial space surrounding a heart at or near a myocardial infarct border zone, is operable to inject a glue-like substance through a lumen of the suction/infusion catheter and out from the one or more apertures to deliver the glue-like substance into the pericardial space at or near the myocardial infarct border zone.

A system for facilitating myocardial infarct border zone reinforcement, comprising:

• an engagement catheter having a proximal end, a distal end, and a lumen positioned therethrough;
• a delivery catheter having a proximal end, a distal end, and a lumen positioned therethrough, the delivery catheter positioned at least partially within the lumen of the engagement catheter;
• and
• at least one suction/infusion catheter positioned at least partially within the lumen of the delivery catheter, the at least one suction/infusion catheter comprising:
• one or more apertures defined along a portion of the at least one suction/infusion catheter at or near a distal end of the at least one suction/infusion catheter;
• a first configuration when the at least one suction/infusion catheter is at least partially extended from a delivery catheter;
• and
• a second configuration when the at least one suction/infusion catheter is positioned within the delivery catheter, the second configuration different from the first configuration;
• wherein the at least one suction/infusion catheter, when introduced into a pericardial space surrounding a heart at or near a myocardial infarct border zone, is operable to inject a glue-like substance through a lumen of the at least one suction/infusion catheter and out from the one or more apertures to deliver the glue-like substance into the pericardial space at or near the myocardial infarct border zone.
