Claim Text:
1. A system for delivering and placement of a medical prosthesis into an ostium of a tract system of an organism, comprising a stent delivery device including: a delivery catheter having a proximal end, a distal end, and at least one lumen extending between the proximal and distal ends; an inflatable balloon mounted on the distal end of the delivery catheter for expanding and deploying the medical prosthesis placed on the balloon; and a stent deployment site locator comprising a locator proximal portion and a locator distal portion, and constituted by a plurality of filament elements forming a flexible structure configured to be expanded into a deployed state for locating an exact place for positioning the medical prosthesis; wherein each said filament element extends from a locator proximal end towards a locator distal end and then returns after winding to the proximal end, thereby to form a plurality of filament loops, the loops being interconnected between the locator proximal end and the locator distal end to form a unitary structure; wherein each loop is connected to an adjacent loop at the locator proximal portion along a continuous length section of the loop to form a strand comprising said continuous length sections of two adjacent filament elements, and, when said locator proximal and distal portions are fully deployed, each loop is overlapped and/or interlaced with at least two neighboring loops at the locator distal portion, wherein the loops are directly bound together at overlapping points of the neighboring loops with formation of intermolecular interaction between the neighboring loops at the overlapping points, thereby providing mechanical strengthening to the stent deployment site locator; and wherein the loops deploy radially outward from each other at the locator distal portion.
