ABSTRACT:
A low profile transvenous electrode system for use in an emergency to sequentially pace both the atrium and ventricle of the heart in a dual chamber mode that includes a plurality of pre-formed, pre-shaped resilient insulated electrical wires bundled together in a tubular, flexible retaining sheath that is used as a guide and delivery system during insertion and removal of the electrode system. When the sheath is retracted, it allows the wires to escape from the sheath and because of their pre-formed shape, each wire having memory, the wires spread out and contact the endocardial surfaces inside the ventricle and atrium chambers. Each of the wires have ball tips to provide high current density and sensitivity.
