Abstract
A method may include delivering a first catheter to a location within an arterial vasculature of a subject. The location may include at least one of an internal carotid artery of the subject or a junction between an ophthalmic artery of the subject and the internal carotid artery of the subject. The method also may include moving a second catheter relative to the first catheter so as to reorient a direction of a distal opening of the second catheter, the second catheter being connected to the first catheter at a joint.
Claims20
A method for treating an eye disorder, comprising:
- accessing an ophthalmic artery (OA) of a subject through an access vasculature site of the subject via a first device;
- positioning a second device within at least a lumen of the OA;
- and
- treating the eye disorder by increasing a size of a first portion of the second device to a first diameter, and increasing a size of a second portion of the second device within the lumen of the OA of the subject to a second diameter, wherein the first diameter is greater than the second diameter.
A method for treating an eye disorder, comprising:
- accessing an internal carotid artery (ICA) of a subject through an access vasculature site of the subject via a first device;
- advancing a second device through a lumen and a port of the first device;
- positioning at least a distal portion of the second device within a lumen of an ophthalmic artery (OA) of the subject;
- and
- treating the eye disorder by increasing a size of a first portion of the second device, to a first diameter, and increasing a size of the second portion of the second device, the second portion of the second device being distal of the first portion of the second device and located within the lumen of the OA, to a second diameter, wherein the first diameter is greater than the second diameter.
A method for treating an eye disorder, comprising:
- accessing an internal carotid artery (ICA) of a subject through an access vasculature site of the subject via a first device;
- advancing a second device through a lumen and a side port of the first device, the second device extending through a distal opening of the first device, making an approximately 180° bend in a first direction so as to reenter the lumen of the first device through the distal opening and form a loop, and bending in a second direction, different from the first direction, so as to extend through the side port of the first device;
- advancing a third device through a lumen of the second device, and positioning at least a portion of the third device within a lumen of an ophthalmic artery (OA) of the subject;
- and
- treating the eye disorder by increasing a size of a distal portion of the third device.
