Stented Valve Having Dull Struts
First Claim
1. A vascular valve replacement system, the system comprising:
- a delivery catheter;
a replacement valve device disposed on the delivery catheter;
the replacement valve device including a prosthetic valve connected to a valve support region of an expandable support structure;
the valve support region having a plurality of struts disposed between a first stent region and a second stent region; and
each strut having a plurality of rounded edges such that the transverse cross-sectional shape of the strut does not have four right angle corners.

Abstract
A system for replacing a pulmonary valve includes a conduit having a lumen, a delivery catheter and a replacement valve device disposed on the delivery catheter. The replacement valve device includes a prosthetic valve connected to a valve support region of an expandable support structure. The valve support region includes a plurality of protective struts disposed between a first stent region and a second stent region. A method for replacing a pulmonary valve includes implanting a conduit and delivering a replacement valve device to the conduit. The replacement valve device includes a valve connected to a valve support region that includes a plurality of protective struts. The method also includes deploying the prosthetic valve device from a delivery catheter into the lumen, positioning the prosthetic valve device within the conduit lumen and expanding the prosthetic valve device into contact with the inner wall of the conduit.
