## Abstract

A delivery device is configured for aligning and stabilizing a prosthetic heart valve for deployment in a native heart valve annulus. The device includes a catheter assembly having an inner shaft around which a valve compartment is defined, an outer shaft assembled over the inner shaft and adapted to slide relative to the inner shaft, a distal sheath connected to a distal end of the outer shaft and slidable therewith, an outer tube assembled over the outer shaft, and an alignment and stabilization device having a collapsed condition and an expanded condition. The outer tube is adapted to slide relative to the outer shaft to selectively cover and uncover the alignment and stabilization device.

## Claims

### Claim 1

A delivery device for a collapsible prosthetic heart valve, comprising:
a catheter assembly comprising:
an inner shaft around which a compartment is defined, the compartment being adapted to receive the prosthetic heart valve in an assembled condition;
an outer shaft assembled over the inner shaft and adapted to slide relative to the inner shaft along a longitudinal axis thereof;
a distal sheath connected to a distal end of the outer shaft and slidable therewith, the distal sheath being adapted to selectively cover and uncover the compartment and the prosthetic heart valve when the prosthetic heart valve is in the assembled condition; and
an outer tube assembled over the outer shaft; and
an alignment and stabilization device having a collapsed condition and an expanded condition, the alignment and stabilization device having one end connected to the outer shaft proximally of the compartment so that the alignment and stabilization device is slidable in a longitudinal direction relative to the outer shaft,
wherein the outer tube is adapted to slide relative to the outer shaft to selectively cover and uncover the alignment and stabilization device.

### Claim 2 (depends on 1)

The device of claim 1, wherein the alignment and stabilization device is formed of braided nitinol.

### Claim 3 (depends on 1)

The device of claim 1, wherein the alignment and stabilization device is substantially funnel shaped in the expanded condition, and the alignment and stabilization device has a longitudinal axis that is coaxial with the outer shaft in the expanded condition.

### Claim 4 (depends on 3)

The device of claim 3, wherein the alignment and stabilization device includes one or more layers of a porous material.

### Claim 5 (depends on 1)

The device of claim 1, wherein the alignment and stabilization device includes a radiopaque marker.

### Claim 6 (depends on 1)

The device of claim 1, wherein the alignment and stabilization device includes a first elongated member having a free end, the free end in the expanded condition being spaced apart from the outer shaft.

### Claim 7 (depends on 6)

The device of claim 6, wherein the alignment and stabilization device further includes a second elongated member having a free end, the second elongated member being connected to the outer shaft at a location that is circumferentially spaced from the first elongated member, the free end of the second elongated member in the expanded condition being spaced apart from the outer shaft.

### Claim 8 (depends on 7)

The device of claim 7, wherein the free ends of the first and second elongated members in the expanded condition have a curled configuration.

### Claim 9 (depends on 1)

A prosthetic heart valve delivery system, comprising:
the delivery device of claim 1; and
a collapsible and expandable prosthetic heart valve assembled in the compartment.

### Claim 10 (depends on 9)

The system of claim 9, wherein the alignment and stabilization device is spaced from the prosthetic heart valve when the prosthetic heart valve is assembled in the compartment and the alignment and stabilization device is in the expanded condition.
