## Abstract

A delivery catheter and a method for deploying a cardiovascular prosthetic implant using a minimally invasive procedure are disclosed. The delivery catheter comprises an elongate, flexible catheter body having a proximal end and a distal end, wherein the distal end has an outer diameter of 18 French or less, a cardiovascular prosthetic implant at the distal end of the catheter body, wherein the cardiovascular prosthetic implant comprises an inflatable cuff and a tissue valve coupled to the inflatable cuff, and at least one link between the catheter body and the cardiovascular prosthetic implant.

## Claims

### Claim 1

A method of deploying a cardiovascular prosthetic implant, the method comprising the steps of:
translumenally advancing a catheter having a distal portion with a diameter of 18 French and carrying a cardiovascular prosthetic implant with a tissue valve having a thickness of at least about 0.011 inches to a position proximate a native valve of a patient, wherein the cardiovascular prosthetic implant comprises an inflatable cuff, a tissue valve coupled to the inflatable cuff;
inflating the inflatable cuff fully with a hardenable inflation media; and
removing the catheter from the patient, leaving the hardenable inflation media in the cardiovascular prosthetic implant within the patient.

### Claim 2 (depends on 1)

The method of claim 1 further comprising before inflating the inflating the inflatable cuff fully with a first media, inflating a distal toroid of the inflatable cuff with a first liquid and positioning the cardiovascular prosthetic implant using the links.

### Claim 3 (depends on 2)

The method of claim 2 displacing the first liquid in the inflatable cuff with a hardenable inflation media.

### Claim 4 (depends on 2)

The method of claim 2, wherein inflating the distal toroid and inflating the inflatable cuff are done using the links.

### Claim 5 (depends on 2)

The method of claim 2, further comprising allowing the inflation media to solidify within the inflatable cuff.

### Claim 6 (depends on 2)

The method of claim 2, further comprising proximally retracting the cardiovascular prosthetic implant after the distal toroid is at least partially inflated.
