Abstract
Devices, systems, and methods for controlling local blood pressure. In an exemplary embodiment of a device for exposing a blood vessel to increased pressure of the present disclosure, the device comprises an anchor configured for placement into a blood vessel and to expand independently from a particle held from flowing away by the anchor, the particle configured to gradually expand due to exposure to blood flow.
Claims20
A device for exposing a blood vessel to increased pressure, the device comprising:
- an anchor configured for placement into a blood vessel along with a particle and to expand independently from the particle;
- and
- the particle, which is held from flowing away by the anchor, configured to gradually expand due to exposure to blood flow within the blood vessel and configured to decrease a cross-sectional area of a lumen of the blood vessel exposed to the blood flow inside the anchor, resulting in a decrease in blood flow and an increase in blood pressure inside the anchor.
A system for exposing a blood vessel to increased pressure, the system comprising:
- an elongated catheter having a balloon coupled thereto;
- and
- an anchor configured for placement into a blood vessel along with a particle and to expand due to inflation of the balloon and independently from the particle;
- and
- the particle, which is held from flowing away by the anchor, configured to gradually expand due to exposure to blood flow within the blood vessel and configured to decrease a cross-sectional area of a lumen of the blood vessel exposed to the blood flow, resulting in a decrease in blood flow and an increase in blood pressure inside the anchor.
A method for exposing a blood pressure to increased pressure, the method comprising:
- positioning an anchor having a particle held from flowing away by the anchor into a lumen of a blood vessel using a balloon catheter, the particle configured to gradually expand due to exposure to blood flow within the blood vessel and configured to decrease a cross-sectional area of a lumen of the blood vessel exposed to the blood flow upon expansion;
- inflating a balloon of the balloon catheter to expand the anchor in the lumen, wherein the anchor is expanded independently of the particle;
- wherein the particle decreases the cross-sectional area of the lumen inside the anchor as it gradually expands due to exposure to blood flow within the lumen, resulting in decreased blood flow and increased blood pressure inside the anchor at a location of the particle.
