Abstract

A thrombectomy catheter deployment for operation of a thrombectomy catheter may include a stand alone drive unit and a disposable pump/catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump/catheter assembly may have a plurality of preconnected components including a tubular structure and a thrombectomy catheter connected thereto. A barcode reader may sense specific operational data pertaining to an individual pump and may provide an interface for operation of the reciprocating linear actuator.

Claims

1. A catheter infusion assembly, comprising:

an infusion catheter attached to a pump;

wherein the pump is configured to insert into a drive unit;

wherein the drive unit is configured to actuate the pump; and

wherein the pump and catheter are coupled together prior to insertion into the drive unit.

2. The infusion assembly of claim 1, wherein the pump is selected from the group comprising a pulsatile pump, an actuation pump, a reciprocating pump, an infusion pump and a piston pump.

3. The infusion assembly of claim 1, wherein the infusion catheter is fixed to the pump.

4. The infusion assembly of claim 1, wherein the pump includes a piston, and wherein the drive unit is configured to actuate the piston.

5. The infusion assembly of claim 1, wherein the catheter, the pump or both the catheter and the pump includes one or more data elements configured to operate the drive unit.

6. The infusion assembly of claim 5, wherein the data elements are configured to operate at least the pump.

7. The infusion assembly of claim 5, wherein the data elements are configured to calibrate the drive unit.

8. The infusion assembly of claim 5, wherein the data elements include a bar code.

9. The infusion assembly of claim 1, wherein catheter infusion assembly further comprises a manifold assembly, the manifold assembly including an infusion port, an effluent port, or both and infusion and effluent port.

10. The infusion assembly of claim 9, wherein the catheter, the pump or both the catheter and the pump includes one or more data elements to operate the drive unit, and wherein the drive unit controls the output of the pump.

11. An infusion catheter and pump assembly, comprising:

an infusion catheter; and

a pump configured to be releasably coupled to a drive unit;

wherein the infusion catheter is fixed to the pump such that the infusion catheter and the pump are fixed together prior to being inserted into the drive unit;

wherein the infusion catheter and/or pump includes at least one data instruction.

12. The infusion assembly of claim 11, wherein the pump is selected from the group comprising a pulsatile pump, an actuation pump, a reciprocating pump, an infusion pump and a piston pump.

13. The infusion assembly of claim 11, wherein the drive unit includes a piston, and wherein the drive unit is configured to control actuation of the piston.

14. The infusion assembly of claim 13, wherein the at least one data instruction controls the drive unit.

15. The infusion assembly of claim 11, further comprising a connection manifold, wherein the connection manifold includes at least one infusion port and at least one effluent port.

16. The infusion assembly of claim 15, wherein the at least one data instruction controls a flowrate of fluid through the infusion port, the effluent port, or both the infusion and effluent port.

17. The infusion assembly of claim 11, wherein the data instruction includes a bar code.

18. A thrombectomy system, comprising:

an infusion catheter including a distal portion, a proximal portion and a lumen extending therein, the infusion catheter including one or more fluid jets located along the distal portion;

a pump fixed to the proximal portion of the infusion catheter; and

a drive unit configured to receive the pump;

wherein the pump include one or more actuation members.

19. The thrombectomy system of claim 18, wherein the pump is selected from the group comprising a pulsatile pump, an actuation pump, a reciprocating pump, an infusion pump and a piston pump.

20. The thrombectomy system of claim 18, wherein the pump includes a piston, and wherein the drive unit actuates reciprocation of the piston such that the piston controls the flowrate of fluid within the catheter lumen.
