Abstract
Described herein are devices, systems, and methods for modifying blood flow and improving tissue oxygenation in an individual. More specifically, described herein are flow modifying implants, delivery systems, and methods of treatment using flow modifying implants. Also described herein are methods for preventing reperfusion injury in an individual using a flow modifying implant to prevent the reperfusion injury.
Claims38
A flow modifying implant that modifies a flow of blood in a blood vessel when deployed, the said flow modifying implant comprising:
- a hollow tubular body having a first end defining an upstream terminus of the hollow tubular body and a second end defining a downstream terminus of the hollow tubular body and the flow modifying implant, the flow modifying implant continuously tapering in decreasing cross-sectional area from the first end to the second end;
- a first opening at the first end of the hollow tubular body and a second opening at the second end of the hollow tubular body, the first opening and the second opening being positioned so that a continuous lumen is formed through the hollow tubular body, wherein the hollow tubular body is fabricated from a material configured to hold a shape of the continuous lumen in a deployed state regardless of direction of flow of blood;
- and
- a ring positioned at the first end so as to form an upstream terminus of the flow modifying implant and positioned coaxially with the first opening, the ring being configured for holding the flow modifying implant in place within the blood vessel,
- wherein the flow modifying implant is configured for implantation into the blood vessel for modifying the flow of blood in the blood vessel,
- wherein the ring comprises a strut, and wherein the hollow tubular body is free of any struts.
A flow modifying implant that modifies a flow of blood in a blood vessel when deployed, the said flow modifying implant comprising:
- a hollow tubular body having a first end defining an upstream terminus of the hollow tubular body and a second end defining a downstream terminus of the hollow tubular body and the flow modifying implant, the flow modifying implant continuously tapering in decreasing cross-sectional area from the first end to the second end, wherein the hollow tubular body is configured to not collapse in a deployed state;
- a first opening at the first end of the hollow tubular body and a second opening at the second end of the hollow tubular body, the first opening and the second opening being positioned so that a continuous lumen is formed through the hollow tubular body;
- and
- a ring positioned at the first end so as to form an upstream terminus of the flow modifying implant and positioned coaxially with the first opening, the ring being configured for holding the flow modifying implant in place within the blood vessel,
- wherein the flow modifying implant is configured for implantation into the blood vessel for modifying the flow of blood in the blood vessel,
- wherein the ring comprises a strut, and wherein the hollow tubular body is free of any struts.
