Claims29
A method of treating a hollow anatomical structure within a human body, comprising:
- inserting a catheter attached to an expandable infusion segment into the hollow anatomical structure,
- wherein the expandable infusion segment comprises a plurality of expandable arms and a plurality of fluid channels, and
- wherein at least one of the plurality of fluid channels is in fluid communication with at least one infusion port;
- advancing the expandable infusion segment to a target site within the hollow anatomical structure;
- expanding the expandable infusion segment to a first diameter;
- delivering a first amount of fluid through at least one infusion port to an inner wall of the hollow anatomical structure;
- adjusting the expandable infusion segment to a second diameter, wherein the second diameter is less than the first diameter;
- and
- delivering a second amount of fluid through the at least one infusion port to the inner wall of the hollow anatomical structure.
A method of treating a varicose vein using schelerosant within a human body, comprising:
- inserting a catheter attached to an expandable infusion segment into the vein,
- wherein the expandable infusion segment comprises a plurality of expandable arms and a plurality of fluid channels, and
- wherein at least one of the plurality of fluid channels is in fluid communication with at least one infusion port;
- advancing the expandable infusion segment to a target site within the vein;
- expanding the expandable infusion segment to a first diameter;
- and
- delivering fluid through at least one infusion port while simultaneously moving the expandable infusion segment along a path of the vein.
A method of treating a thrombus mass within a human body, comprising:
- inserting a catheter attached to an expandable infusion segment into the human body,
- wherein the expandable infusion segment comprises a plurality of expandable arms and a plurality of fluid channels, and
- wherein at least one of the plurality of fluid channels is in fluid communication with at least one infusion port;
- advancing the expandable infusion segment to the thrombus mass;
- delivering a first amount of fluid through at least one infusion port to the thrombus mass while the expandable infusion segment is at a first diameter;
- adjusting the expandable infusion segment to a second diameter, wherein the second diameter is different than the first diameter;
- and
- delivering a second amount of fluid through the at least one infusion port to the thrombus mass.
