First Claim
Patent Images
1. A device for implantation in a vessel, the device comprising:
- a series of struts configured in a circumferential pattern comprising peaks and valleys and defining a lumen of the device, each strut having an outer surface and an inner surface, the inner surfaces generally defining an inner outline of the device,wherein at least one strut is curved along a radial direction with respect to the lumen.

Abstract
A device for implantation in a vessel is provided with a geometry designed to reduce the drag experienced by the device when deployed using a sheathed delivery system. Sections of the device are provided with regions of high-points and low-points on the device'"'"'s outer surface by curving one or more of the struts of the device. The high points serve as the contact points of the device with the sheath as the sheath and the delivery system are withdrawn from between the device and the vessel.

14. A method of forming an implantable device comprising at least one strut having reduced drag characteristics with respect to a delivery sheath, the method comprising:
-
providing a first texture pattern and a second texture pattern provided thereon, each of the first and second texture patterns configured to complement the other; positioning the implantable device between the first and second texture patterns; and imparting a shape corresponding to the first and second texture patterns to at least one strut of the device. - View Dependent Claims (15, 16, 17)
