摘要：A system forms a cardiac conduction block at a location in a heart of a patientwithout substantially ablating cardiac tissue. The system includes a delivery systemcoupled to a source of material that is substantially non-ablative with respect to cardiactissue. The delivery system delivers the material to the location, and the material at thelocation forms a conduction block without ablating the cardiac cells there. The materialmay include living cells, such as for example skeletal myocytes, and/or may include a non-living matter such as biopolymers such as a fibrin glue agent. An expandable memberwith needle assembly is used to deliver the material so as to form a non-ablativecircumferential conduction block at a location where a pulmonary vein extends from anatrium.
