Deployment system for myocardial cellular material
First Claim
1. A deployment system for myocardial cellular material, comprising:
- 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 material can be deployed into the myocardial wall from inside the lumen.

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).

20. A method of deploying 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 material can be deployed into the myocardial wall from inside the lumen;
advancing the guiding catheter through a patient'"'"'s body to the myocardial wall;
deploying the needle assembly by inserting the tip of the needle assembly into the myocardial wall to a predetermined depth;
extending an implement through the opening in the side of the tip and engaging the implement directly with the myocardial wall;
retracting the implement and inserting a myocardial cellular material into the lumen of the needle assembly;
deploying the myocardial cellular material into the myocardial wall through the opening in the side of the tip. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
