Abstract
The present invention provides improved devices and methods for establishing intercostal access for subsequent placement of minimally invasive direct cardiac massagers, chest tubes, defibrillation electrodes, and the like. In particular, the present invention provides devices and methods which facilitate rapid, safe, and sterile intercostal dissection for the subsequent deployment of minimally invasive direct cardiac massagers. An intercostal device according to the present invention comprises a support having a proximal end and a distal end, a cutting tip coupled to the distal end of the support, and rib engaging means coupled to the support or cutting tip. The cutting tip is adapted to penetrate percutaneously through intercostal tissue between adjacent ribs to a thoracic cavity over a heart. Means coupled to the support or cutting tip penetrate or dilate tissue, engage at least one rib, and stop advancement of the cutting tip into the thoracic cavity.
