Lead with inter-electrode spacing adjustment
First Claim
1. A lead with inter-electrode spacing adjustability, to be introduced in a patient'"'"'s body, comprising in combination:
- an elongated lead body extending between a tip at a distal end, and a proximal end;
an outer sheath extending coaxially with at least part of said lead body, between said proximal end and said distal end, said outer sheath including a ventricular section in proximity to said distal end of said lead body having an expandable member for enabling said outer sheath to slide coaxially relative to said lead body, a proximal section substantially overlaying said proximal end of said lead body, and an atrial section that is slidably adjustable between said ventricular section and said proximal section; and
one or more effective electrodes including one or more windows that are positioned along said outer sheath, adjustable relative to said tip by sliding said outer sheath along said lead body.

Abstract
A single-pass transvenous lead for atrial sensing and pacing, ventricular sensing and pacing, as well as for ventricular and atrial defibrillation. The lead optimizes the positioning of the electrodes in various patients regardless of variations in these patients'"'"' hearts, by enabling independent adjustment of the spacing between various pacing, sensing and defibrillation electrodes, before and after implantation or insertion in the heart. The lead includes an elongated lead body, an outer sheath that extends coaxially with the lead body, and two atrial windows positioned along the outer sheath, adjustable relative to a reference point such as a distal pacing tip. The outer sheath includes an atrial section that is slidably adjustable along the lead body by means of an expandable member.
