Abstract:
The invention relates to a method for producing a radially expandable prosthesis by laser cutting a pattern in a tubular member, which member has an outer diameter at least as great as the expanded diameter of the prosthesis. The prosthesis may be a Z-stent which can be cut out to have integral barbs or notches along its struts. The apexes between the struts may be relatively thin.
Abstract:
A stent deployment device (110) is provided for deploying a stent in a lumen of a patient. The device can include a catheter (112), a first balloon (122) positioned near a distal end of the catheter and a second balloon (123) adjacent to the first balloon. Alternatively, the second balloon can be positioned over the first balloon. The device also includes an expandable stent (210) positioned over the first balloon and the second balloon. The first balloon comprises a semi-compliant material, a noncompliant material or a compliant material. Similarly, the second balloon comprises a semi-compliant material, a noncompliant material or a compliant material. The first balloon is expandable to a first diameter, while the second balloon can be expandable to a second diameter.
Abstract:
A system and method for repairing one or more vessels includes a branch vessel prosthesis (11) for use with an aorta stent graft (1) defining a lumen and having a fenestration (7) aligned with a branch vessel. The branch vessel prosthesis includes a flaring portion (36) and a tubular portion (33), where the flaring portion is retained within the lumen of the aorta stent graft and the tubular portion passes through the fenestration and into the branch vessel.
