Patent Images
1. A modular vascular prosthesis having a delivery configuration and an deployed configuration, the vascular prosthesis comprising:
- a radially expandable first segment having proximal and distal ends;
a radially expandable second segment having proximal and distal ends;
a plurality of first inter-engageable elements extending from the distal end of the first segment; and
a plurality of second inter-engageable elements extending from the proximal end of the second segment, wherein the plurality of first inter-engagable elements are engaged in the plurality of second inter-engageable elements to permit articulation of the first segment relative to the second segment in the delivery configuration.

Abstract
The present invention provides a vascular prosthesis featuring a plurality of modular segments interengaged by flexible, and preferably lockable, inter-engageable elements forming joints. The segments may have a number of different mechanical properties and may be assembled by the clinician to customize the prosthesis for a specific patient or application.
