Apparatus and methods for assisted breathing by transvascular nerve stimulation
First Claim
1. A catheter, comprising:
- an outer sheath defining a plurality of apertures therethrough;
a body defining at least one longitudinal lumen therein, wherein at least a portion of the body is radially inward of the outer sheath, and the apertures are radially outward of the lumen;
a plurality of electrodes positioned in or on the catheter, each electrode being electrically exposed through an aperture of the plurality of apertures; and
a ribbon cable extending through the lumen and including a plurality of leads, the plurality of leads being electrically connected to the plurality of electrodes,wherein the plurality of apertures includes a plurality of proximal apertures and a plurality of distal apertures, the plurality of proximal apertures including two longitudinally extending rows of proximal apertures, and wherein the outer sheath includes (1) a first radiopaque feature at a distal portion of the sheath for confirming an orientation of the distal apertures and (2) a second radiopaque feature at a proximal portion of the sheath and positioned circumferentially opposite to a line extending between the two rows of proximal apertures.

Abstract
A catheter may include an outer layer defining a plurality of apertures therethrough, and a body defining at least one longitudinal lumen therein. The body may be within the outer layer, and the apertures may be radially outward of the lumen. The catheter may also include a plurality of electrodes positioned in or on the catheter, with each electrode being electrically exposed through an aperture of the plurality of apertures. A ribbon cable may extend through the lumen and include a plurality of leads, with the plurality of leads being electrically connected to the plurality of electrodes. The plurality of leads and electrodes may be formed by the deposition of conductive inks or paints, or by the electrodeposition of copper or other conductive metals or materials.
