    摘要: A catheter system includes a catheter having a proximal end, a distal end, and a lumen extending therein. An administering portion is disposed at the distal end of the catheter and is configured to administer a bolus of liquid in response to positive pressure in a distal portion of the lumen. The catheter system of the present invention has a dead space of less 0.32 cc and preferably less than 0.15 cc in which residual therapeutic agents remain after delivery. The present invention also includes a method of administering a liquid to a treatment site. The distal end of the catheter is transluminally positioned proximate the treatment site. The catheter is charged by placing a bolus of the liquid in the lumen A positive pressure is created to drive the bolus to the administering tip to express the bolus from the distal end of the catheter.

    摘要: Devices and methods for increasing blood perfusion within the myocardium of the heart by wounding the myocardium and applying growth factors to promote vascularization. One method includes driving spikes into the myocardium from within the heart, with the spikes being formed of biodegradable material, containing releasable growth factors, and having lumens and side holes. An alternative method utilizes non-biodegradable spikes with lumens and side holes. Another method promotes vascularization by injecting angiogenic material into holes bored into the myocardium, leaving a patent hole. Another method includes injecting angiogenic material into the myocardium without boring, leaving no patent hole. The angiogenic material can be carried in a biodegradable adhesive. Revascularization of the myocardium is promoted in one method by externally wounding the heart and applying a patch including growth factors.
