Abstract:
A method of performing percutaneous myocardial revascularization of a patient comprising:collecting autologous biological material from the patient; preparing the autologous biological material to form an angiogenic agent; providing a catheter adapted for insertion into the left ventricle comprising a hollow stabilizer element and a cutting head movable from a retracted position to an extended position; advancing a distal region of the catheter transluminally to a position within the patient's left ventricle; deploying the stabilizer element to stabilize the distal region of the catheter in contact with an endocardial surface; advancing the cutting head from the retracted to the extended position to bore a channel into the patient's cardiac tissue; and injecting an amount of the angiogenic agent through the hollow stabilizer element into a region of the patient's cardiac tissue adjacent to the channel.
