Abstract

Claims (40)

1 . An apparatus, comprising:

a thrombectomy pump;

a housing including a collection chamber and a pump chamber, the thrombectomy pump coupled within the pump chamber;

an aspiration tube extending from the thrombectomy pump within the pump chamber;

a clot retainer coupled to the housing within the collection chamber, the clot retainer having a porous surface to allow liquid to flow through the surface and into the collection chamber; and

a lid removably coupled to the housing to cover the clot retainer, the lid including a transparent portion to allow viewing of the clot retainer through the lid,

a portion of the aspiration tube extending horizontally and in fluid communication with an outlet port in a side wall of the collection chamber such that the liquid flows into the collection chamber above the porous surface of the clot retainer, through the clot retainer, and into the collection chamber.

2 . The apparatus of claim 1 , wherein:

the housing has a base surface, the surface of the clot retainer is disposed at a first distance from the base surface of the housing, and

the outlet port in the side wall of the collection chamber is at a second distance from the base surface, the second distance being greater than the first distance.

3 . The apparatus of claim 1 , wherein:

the thrombectomy pump is coupled to the aspiration tube to provide fluid communication between the thrombectomy pump and the collection chamber.

4 . The apparatus of claim 1 , wherein:

the collection chamber surrounds at least a portion of the pump chamber.

5 . The apparatus of claim 1 , wherein:

the collection chamber has a volume of at least 1000 cubic centimeters.

6 . The apparatus of claim 1 , wherein the thrombectomy pump is a peristaltic pump.

7 . An apparatus, comprising:

a housing including a first housing portion and a second housing portion, the second housing portion defining a pump chamber and a collection chamber, the collection chamber at least partially encircles the pump chamber;

a pump assembly disposed within the pump chamber, the pump assembly including an inlet port configured to be coupled to a catheter and an outlet port in fluid communication with the collection chamber;

the pump assembly including a pump, a sensor, and a controller;

the first housing portion coupled to the second housing portion and enclosing the pump chamber; and

a touch screen coupled to the first housing portion and operably coupled to the controller.

8 . The apparatus of claim 7 , further comprising:

a lid removably coupled to the second housing portion and enclosing at least a portion of the collection chamber.

9 . The apparatus of claim 7 , wherein:

the collection chamber includes a clot cavity, the clot cavity in direct fluid communication with the outlet port.

10 . The apparatus of claim 9 , further comprising:

a clot retainer having a porous bottom surface to allow liquid to flow through the bottom surface and into the collection chamber.

11 . The apparatus of claim 10 , wherein:

a lid disposable over the clot retainer, the lid including a transparent portion to allow viewing of the clot retainer through the lid.

12 . The apparatus of claim 10 , wherein:

the housing has a base surface, the outlet port being positioned at a first distance relative to the base surface, the bottom surface of the clot retainer being disposed at a second distance from the base surface, the first distance being greater than the second distance.

13 . The apparatus of claim 10 , wherein:

the outlet port extends parallel with the bottom surface of the clot retainer.

14 . The apparatus of claim 7 , further comprising:

an aspiration tube coupled to the pump within the pump chamber, a portion of the aspiration tube extending within the outlet port and in fluid communication with the collection chamber.

15 . The apparatus of claim 7 , wherein the pump is a peristaltic pump.

16 . The apparatus of claim 7 , wherein:

the collection chamber has a volume of at least 1000 cubic centimeters.
