Deployment system for myocardial cellular material
First Claim
1. A deployment system for a myocardial cellular material, comprising:
- a guiding catheter having at least one lumen defined therein;
a needle assembly capable of sliding through the lumen of the guiding catheter, the needle assembly having a lumen defined therein and terminating in a tip, the tip having at least one side, the needle assembly having an opening in the at least one side of the tip disposed in communication with the lumen of the needle assembly so that the myocardial cellular material can be deployed into a myocardial wall from inside the lumen of the needle assembly;
a push rod having a platform disposed at its distal end, the rush rod disposed inside the lumen of the needle assembly; and
an anchor wire disposed axially through the tip and capable of engaging with a portion of the myocardial wall to position the needle assembly relative to the myocardial wall,wherein the guiding catheter has an outer wall having a distal end, wherein the distal end comprises a sensor and forms an anchor extending frontwardly so as to hold the guiding catheter in a position against the myocardial wall.

Abstract
A catheter-based deployment system for deploying cellular material (22) into the heart muscle (25). The deployment system includes a guiding catheter (19) and a needle assembly (31) capable of sliding within the guiding catheter. The needle assembly (31) terminates in a tip (34) having at least one side with an opening (43) in communication with a lumen (20) disposed within the needle assembly (31). Once the guiding catheter (19) is positioned the needle assembly (31) is advanced until the tip (34) penetrates the muscle wall (25). At a predetermined depth the cellular material (22) may be deployed into the muscle wall (25) via a push rod (46) disposed through the lumen of the needle assembly (31).

3. A method of deploying a myocardial cellular material, comprising:
-
providing a guiding catheter having at least one lumen defined therein and a needle assembly capable of sliding through the lumen of the guiding catheter, the needle assembly having a lumen defined therein and terminating in a tip, the tip having at least one side, the needle assembly having an opening in the at least one side of the tip disposed in communication with the lumen of the needle assembly so that the myocardial cellular material can be deployed into a myocardial wall from inside the lumen of the needle assembly; advancing the guiding catheter through a patient'"'"'s body to the myocardial wall and utilizing an anchor wire disposed axially through the tip as a guidewire to engage the myocardial wall and position the needle assembly relative to the myocardial wall, wherein the guiding catheter has an outer wall having a distal end, wherein the distal end forms an anchor extending frontwardly so as to hold the guiding catheter in a position against the myocardial wall; deploying the needle assembly by inserting the tip of the needle assembly into the myocardial wall to a predetermined depth; extending a push rod having a platform through the opening in the side of the tip and engaging the platform directly with the myocardial wall; retracting the platform and inserting the myocardial cellular material into the lumen of the needle assembly; and deploying the myocardial cellular material into the myocardial wall through the opening in the side of the tip. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)
