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

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.

2. 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.

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

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

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

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