## Abstract

An intravascular cuff acts as a lining between a native vessel and an intravascular prosthetic device. During deployment, the ends of the cuff curl back upon themselves and are capable of trapping native tissue, such as valve leaflet tissue, between the ends. The cuff creates a seal between the vessel and the prosthetic, thereby preventing leakage around the prosthetic. The cuff also traps any embolic material dislodged from the vessel during expansion of the prosthetic.

## Claims

### Claim 1

An intravascular cuff for receiving a prosthetic, comprising:
at least one strand braided to form a tubular structure having an extended configuration and a deployed configuration;
whereby in the extended configuration, the tubular structure includes:
a first end and a second end;
a tubular body between the first end and the second end;
a lumen extending through the body;
whereby in the deployed configuration, the first and second ends assume an expanded shape relative to the tubular body.

### Claim 2 (depends on 1)

The intravascular cuff for receiving a prosthetic of claim 1 wherein said at least one strand comprises a shape memory material.

### Claim 3 (depends on 1)

The intravascular cuff for receiving a prosthetic of claim 1 wherein said at least one strand comprises a super-elastic material.

### Claim 4 (depends on 2)

The intravascular cuff for receiving a prosthetic of claim 2 wherein said at least one strand comprises Nitinol.

### Claim 5 (depends on 1)

The intravascular cuff for receiving a prosthetic of claim 1 wherein said tubular body between the first end and the second end comprises a two-ply body.

### Claim 6 (depends on 1)

The intravascular cuff for receiving a prosthetic of claim 1 wherein said tubular body between the first end and the second end comprises a two-ply body, formed by inverting said tubular body within itself to create a folded end and an unbraided end.

### Claim 7 (depends on 5)

The intravascular cuff for receiving a prosthetic of claim 5 further comprising a material sandwiched between said first and second ply.

### Claim 8 (depends on 7)

The material of claim 7 wherein said material is selected from the group consisting of non-woven material, woven material, braided fabric and polymer.

### Claim 9 (depends on 1)

The intravascular cuff for receiving a prosthetic of claim 1 wherein the expanded shape of the ends comprises a mushroom shape defined by an outer ply and an inner ply separated by a gap.

### Claim 10 (depends on 9)

The intravascular cuff for receiving a prosthetic of claim 9 wherein the inner ply forms a funnel in the deployed configuration.

### Claim 11 (depends on 1)

The intravascular cuff for receiving a prosthetic of claim 1 wherein the tubular body between the first end and the second end retains a relatively unexpanded state in the deployed configuration.

### Claim 12 (depends on 1)

The intravascular cuff for receiving a prosthetic of claim 1 wherein the tubular body shortens when expanded from the deployed state.

### Claim 13

An intravascular cuff comprising:
at least one strand braided to form a tubular device having a lumen extending therethrough, the device having elongated, relaxed, and expanded configurations;
whereby in the elongated configuration, the tubular device is capable of insertion into a catheter;
whereby in the relaxed configuration, the tubular device has a first end and a second end having diameters greater than that of a body portion between the first and second ends;
whereby in the expanded configuration, the tubular device has a length shorter than a length of the device in the relaxed configuration.

### Claim 14 (depends on 13)

The intravascular cuff of claim 13 wherein said at least one strand comprises Nitinol.

### Claim 15 (depends on 13)

The intravascular cuff of claim 13 wherein said tubular device comprises a two-ply body.

### Claim 16 (depends on 13)

The intravascular cuff for receiving a prosthetic of claim 13 wherein said tubular body between the first end and the second end comprises a two-ply body, formed by inverting said tubular body within itself to create a folded end and an unbraided end.

### Claim 17 (depends on 15)

The intravascular cuff of claim 15 further comprising a material disposed between the two plies.

### Claim 18 (depends on 17)

The intravascular cuff of claim 17 wherein said material comprises a fabric.

### Claim 19 (depends on 13)

The intravascular cuff of claim 13 wherein at least one of the ends folds back on itself in the relaxed configuration in order to achieve said greater diameter.

### Claim 20 (depends on 13)

The intravascular cuff of claim 13 wherein said lumen is flared outwardly proximate the first and second ends in the relaxed configuration.
