## Abstract

An apparatus comprising an input connector configured for sterile connection to a fluid source, a first tube, a second, and a third tube. The first tube extends from a proximal end to a distal end, the proximal end comprising an input connector configured for sterile attachment to a fluid source. The input connector provides fluid communication between the first tube and the source. The second and third tubes are each in fluid communication with the first tube. The second and third tubes each extend from a proximal end to a distal end comprising an output connector configured for sterile connection to separate fluid input ports of a catheter based device.

## Claims

### Claim 1

An apparatus comprising:
a catheter based device;
a first tube extending from a proximal end to a distal end, said proximal end comprising an input connector configured for sterile attachment to a fluid source to provide fluid communication between the first tube and the source; and
a second and a third tube, each in fluid communication with the first tube and each extending from a proximal end to a distal end comprising an output connector configured for sterile connection to a respective fluid input port of the catheter based device;
wherein the catheter based device is a percutaneous ventricle assist device having a first fluid input port for a pump purge line and a second fluid input port for a placement signal line;
wherein the output connector of the second tube provides fluid communication between the second tube and the first fluid input port; and
wherein the output connector of the third tube provides fluid communication between the third tube and the second fluid input port.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising a visual indication that facilitates proper coupling of the output connectors to the percutaneous ventricle assist device.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the output connectors are color coded to a respective one of the first and second fluid input ports.

### Claim 4 (depends on 1)

The apparatus of claim 1, further comprising a pressure transducer coupled to the first tube.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein fluid input into the proximal end of the first tube from the fluid source will flow through the first tube to the distal end of the first tube and be divided into at least:
a) a first portion flowing through the second tube from the proximal end of the second tube to distal end of the second tube, and
b) a second portion flowing through the third tube from the proximal end of the third tube to distal end of the third tube.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the at least one of the input connector and the output connecters is a Luer connector.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein each of the output connectors is a male Luer connector.

### Claim 8 (depends on 1)

The apparatus of claim 1, further comprising the fluid source, and wherein the fluid source comprises a pressure bag.
