Abstract
A device may include an elongated catheter body having a proximal portion and a distal portion, wherein the distal portion forms a memorized shape when unconstrained; the memorized shape comprising a plurality of curves positioned to orient the distal portion within a right subclavian artery or brachiocephalic artery and also into a left common carotid artery.
Claims26
A select catheter, comprising:
- an elongated catheter body comprising a distal region with a constrained linear shape and an unconstrained shape;
- wherein the distal region comprises a distal first section and a proximal second section that forms a major curve with the proximal second distal first section in the unconstrained shape, wherein the distal first section is distally located relative to the proximal second section in the constrained linear shape;
- and,
- where in the unconstrained shape:
- the proximal second section lies substantially in a first reference plane;
- the distal first section is positioned at least partially outside of the first reference plane;
- and,
- the distal first section and the proximal second section do not lie substantially entirely in a common plane.

A select catheter, comprising:
- an elongated catheter body comprising a distal region with an unconstrained shape;
- wherein the distal region comprises a first distal section that forms a major curve with a second distal section in the unconstrained shape;
- and,
- wherein the unconstrained shape of the first distal section is positioned at a non-parallel angle relative to the second distal section and wherein a free distal tip of the distal region is positioned in a generally proximal orientation;
- wherein the first distal section and the second distal section do not lie substantially entirely in a common plane.
2 more elements
A select catheter, comprising:
- an elongated catheter body comprising a distal region with an unconstrained shape means for accessing a right common carotid artery or left common carotid artery via radial access;
- wherein the distal region comprises a first distal section that forms a major curve with a second distal section;
- wherein the first distal section and the second distal section do not lie substantially entirely in a common plane.
