## Abstract

An extension member is has a body with a proximal end and an opposing distal end. It includes a hollow lumen extending therethrough from the proximal end to the distal end. It has a female luer lock connector proximate its proximal end and a male luer lock connector proximate its distal end. Its body has an outeHr surface with a driven member.

## Claims

### Claim 1

An apparatus comprising:
a drive motor coupled to a drive member;
a hemostasis valve including a valve body having a proximal port, a distal port and a lumen extending between the proximal port and the distal port, at least one valve being located in the lumen to permit an interventional device to be passed therethrough, a rotating luer lock connector of the hemostasis valve rotatably connected to the valve body proximate the distal port;
an extension member having an extension member body with a proximal end and an opposing distal end, the extension member body including a hollow lumen extending therethrough from the proximal end to the distal end, the extension member body having a female luer connector proximate the proximal end and a male luer connector proximate the distal end, the female luer connector of the extension member being removably secured to the rotating luer lock connector of the hernostasis valve at the proximal end of the extension member, the male luer connector of the extension member being configured to removably secure a catheter thereto, the body of the extension member having a driven member configured to be rotatably driven by the drive member;
wherein rotation of the drive member imparts rotation to the extension member and the catheter while isolating the hemostasis valve from rotational motion; and
a controller providing instructions to the motor via a user interface to rotate the driven member and the extension member; and
the driven member being removable from the drive member while the guide catheter is operatively secured to the hemostasis valve.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the drive member is a gear, and the valve body includes a first leg having the proximal port; the valve being adjacent the proximal port; the valve body including a second leg extending at an angle relative to the first leg and in fluid communication with the first leg; and wherein the catheter is a guide catheter.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the driven member is a beveled gear having a plurality of teeth facing toward the proximal port, the gear of the drive member having a plurality of teeth operatively engaged with the plurality of teeth of the beveled gear.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the proximal end of the valve body is configured to receive a guide wire and a working catheter through the lumen.

### Claim 5 (depends on 1)
