Abstract
The invention relates to an implantable device (1) for determining a fluid volume flow (2) through a blood vessel (3), comprising: —at least one sensor (4) for recording at least one flow parameter, —a retaining means (5) for retaining a vessel wall port (6) in the region of a vessel wall (7) of the blood vessel (3), wherein the retaining means (5) is formed to retain the at least one sensor (4) in the region of the vessel wall (7).
Claims18
A device for determining a blood volume flow through a blood vessel, comprising:
- at least one sensor configured to detect at least one flow parameter of blood in the blood vessel, the blood vessel being in fluid communication with a pump of a cardiac assist system configured to be implanted in the blood vessel;
- a cuff configured to at least partially encircle an exterior wall of the blood vessel and retain the at least one sensor in or on the exterior wall;
- and
- a vessel wall port coupled to the cuff, the vessel wall port shaped to penetrate the exterior wall of the blood vessel to receive a portion of the cardiac assist system therethrough, wherein the cuff comprises at least one opening configured to receive the vessel wall port and retain the vessel wall port in a desired circumferential position in or on the exterior wall.
A system comprising:
- a cardiac assist system configured to be implanted within a blood vessel;
- and
- a device configured to determine blood volume flow of blood within the blood vessel, the device comprising:
- at least one sensor configured to detect at least one flow parameter of the blood in the blood vessel;
- a cuff configured to at least partially encircle an exterior wall of the blood vessel and retain the at least one sensor in or on the exterior wall;
- and
- a vessel wall port coupled to the cuff, the vessel wall port shaped to penetrate the exterior wall of the blood vessel to receive a portion of the cardiac assist system therethrough, wherein the cuff comprises at least one opening configured to receive the vessel wall port and retain the vessel wall port in a desired circumferential position in or on the exterior wall.
A method for determining a blood volume flow through a blood vessel having a cardiac assist system configured to be implanted therein, the method comprising:
- performing a measurement with at least one sensor of a device, the device comprising:
- a cuff configured to at least partially encircle an exterior wall of the blood vessel and retain the at least one sensor in or on the exterior wall;
- and
- a vessel wall port coupled to the cuff, the vessel wall port shaped to penetrate the exterior wall of the blood vessel to receive a portion of the cardiac assist system therethrough, wherein the cuff comprises at least one opening configured to receive the vessel wall port and retain the vessel wall port in a desired circumferential position in or on the exterior wall;
- and
- determining the blood volume flow based at least in part on the measurement.
