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.

Independent Claims | See all claims (18)

1. 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.
2. 9. A pulmonary valve replacement system, the system comprising: a conduit having an interior wall forming a lumen; a replacement valve device, the replacement valve device including a prosthetic valve connected to a valve support region of an expandable support structure, wherein the valve support region includes a plurality of protective struts disposed between a first stent region and a second stent region.
3. 17. A method for replacing a pulmonary valve, the method comprising: implanting a conduit into a target region of a vascular system, the conduit having an inner wall defining a lumen; delivering a replacement valve device to the lumen of the conduit, the replacement valve device including a valve connected to a valve support region of an expandable support structure, the valve support region including a plurality of protective struts disposed between a first stent region and a second stent region of the expandable support structure; 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.
