Abstract
A catheter, a kit and a method of using the catheter for removing a thrombus from a blood vessel in a mammal. The catheter includes a tubular body with a hollow interior, an exterior surface, a proximal end, and a distal end and a plurality of protrusions extending upwardly from the exterior surface, wherein each protrusion has an aperture. The distal end of the catheter is inserted into the blood vessel and a suction is applied to the proximal end of the catheter to aspirate the thrombus from the blood vessel. The kit includes the catheter, a suction device and a mechanism for controlling the suction flow.
Claims18
A catheter for removing a thrombus from the interior surface of a blood vessel, the catheter comprising:
- a tubular body having a hollow interior, an exterior surface, a proximal end, and a distal end;
- and
- a plurality of protrusions extending upwardly from the exterior surface, wherein each protrusion comprises an aperture, a top surface and a perimetrical side wall extending between the top surface and the exterior surface of the catheter, and wherein the aperture is in the top surface and the perimetrical side wall is circumferentially formed entirely around the aperture,
- wherein the distal end of the catheter is inserted into the blood vessel and a suction is applied to the proximal end of the catheter to aspirate the thrombus from the blood vessel.
A kit for removing a thrombus from the interior surface of a blood vessel, the kit comprising:
- a catheter comprising:
- a tubular body having a hollow interior, an exterior surface, a proximal end, and a distal end;
- and
- a plurality of protrusions extending upwardly from the exterior surface, wherein each protrusion comprises an aperture, a top surface and a perimetrical side wall extending between the top surface and the exterior surface of the catheter, wherein the aperture is in the top surface and the perimetrical side wall is circumferentially formed entirely around the aperture,
- wherein the distal end of the catheter is inserted into the blood vessel and a suction is applied to the proximal end of the catheter to aspirate the thrombus from the blood vessel;
- a suction device connected to the proximal end of the catheter, wherein the suction device introduces a negative pressure and a suction flow into the catheter;
- and
- a mechanism located between the proximal end of the catheter and the suction device for controlling and actuating the suction flow.
A method of removing a thrombus from a blood vessel in a mammal, the method comprising:
- inserting a catheter into the blood vessel of the mammal, wherein the catheter comprises:
- a tubular body having a hollow interior, an exterior surface, a proximal end, and a distal end;
- and
- a plurality of protrusions extending upwardly from the exterior surface, wherein each protrusion comprises an aperture, a top surface and a perimetrical side wall extending between the top surface and the exterior surface of the catheter, wherein the aperture is in the top surface and the perimetrical side wall is circumferentially formed entirely around the aperture;
- and
- aspirating the thrombus by applying a suction to the distal end of the tubular body of the catheter to create a suction flow.
