ABSTRACT:
Transvenous leads including an outer atrial and an inner ventricular spaced wound coils coaxial with respect to each other and including a closed fixation loop connected to the outer lead. The closed fixation loop extends outwardly at an angle with respect to the outer lead. An inner lead is slideably adjustable within the outer lead and supports a ventricular electrode. The outer lead supports an atrial electrode. A connector at the other end of the leads supports and secures a connector pin for the outer lead in one sleeve and provides for slideable adjustment of the inner lead which includes a proximal tip in the other sleeve. An O-ring engages in an O-ring groove in the other sleeve to provide a liquid seal between the atrial coil and the end of the ventricular coil. The proximal tip and connector pin connect to a pulse generator. The transvenous leads with the closed fixation loop are intended for pacing the ventricular and atrial chambers of a heart.
