20090259212 | APPARATUS AND METHOD FOR CONTROLLED DEPTH OF INJECTION INTO MYOCARDIAL TISSUE - An injector apparatus and associated methods for safely and repeatedly delivering an injectate at a predefined depth into the myocardium of the heart may be catheter-based or implemented in a handheld unit for use in open chest procedures. The injector includes a body, a stabilizer secured to a distal end of the body for stabilizing the distal end of the body relative to the myocardium, and a needle that may be controllably advanced from the distal end of the body into the myocardium. The stabilizer employs any suitable technique for stabilizing the distal end of the catheter body relative to the myocardium while the heart is beating. An enlarged region disposed along the needle functions as a stop to prevent the needle from being advanced into the myocardium beyond a desired penetration depth. To make an injection, the physician brings the distal end of the body in proximity to the endocardium or the epicardium using any suitable technique, actuates the stabilizer to stabilize the distal end relative to the myocardium; and advances the needle into the myocardium. Advancement of the needle into the myocardium is impeded by the enlarged region, thereby placing the needle tip at the desired penetration depth and avoiding puncturing of the heart. The injection is then made, and the needle and catheter are removed. | 10-15-2009 |
