Medical systems, devices, and related methods
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.
1. A method, comprising:
delivering a first catheter to a location within an arterial vasculature of a subject, the location including 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; and
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,
wherein the joint couples a distal end of the second catheter relative to a distal end of the first catheter.
2. The method of claim 1 , wherein the moving the second catheter includes bending the second catheter.
3. The method of claim 2 , further including adjusting a degree of bending of the second catheter.
4. The method of claim 1 , further including directing a guide wire through the distal opening of the second catheter and into the ophthalmic artery.
5. The method of claim 1 , further including securing the second catheter relative to the first catheter via a balloon.
6. The method of claim 1 , further including applying aspiration to the location via the second catheter.
7. The method of claim 1 , wherein the joint includes a hinge.
8. A method, comprising:
delivering a first catheter to a location within an internal carotid artery of a subject;
manipulating a second catheter at least partially received within the first catheter, wherein the manipulating includes adjusting an angle of a distal opening of the second catheter relative to an axis of the first catheter; and
securing a position of the second catheter relative to the first catheter.
9. The method of claim 8 , wherein adjusting the angle includes positioning the distal opening to face an ophthalmic artery of the subject.
10. The method of claim 8 , further including advancing the distal opening of the second catheter through a side port of the first catheter, wherein the side port extends through a side wall of the first catheter between a proximal end of the first catheter and a distal end of the first catheter.
11. The method of claim 10 , further including adjusting a degree of expansion of an expandable member associated with the side port.
12. The method of claim 8 , wherein the manipulating the second catheter includes steering the second catheter to form a first bend, the first bend being approximately 90° or approximately 180°.
13. The method of claim 12 , wherein the first bend is approximately 180°, and the manipulating the second catheter further includes steering the second catheter to form a second bend, the second bend being approximately 90°.
14. The method of claim 8 , further including applying aspiration via the second catheter.
15. A method, comprising:
delivering a first catheter to a location within an arterial vasculature of a subject, the location including 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;
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, wherein the moving the second catheter includes bending the second catheter, and wherein the joint couples a distal end of the second catheter relative to a distal end of the first catheter; and
securing the second catheter relative to the first catheter via a balloon.
16. The method of claim 15 , further including adjusting a degree of bending of the second catheter.
17. The method of claim 15 , further including applying aspiration to the location via the second catheter.
18. The method of claim 15 , wherein the joint includes a hinge.
19. The method of claim 15 , further including directing a guide wire through the distal opening of the second catheter and into the ophthalmic artery.
20. The method of claim 15 , wherein reorienting the direction of the distal opening of the second catheter includes positioning the distal opening to face the ophthalmic artery of the subject.
