Intravascular flow modifier and reinforcement device with connected segments
First Claim
1. A stent for use in the intravascular treatment of blood vessels, comprising:
- a first half-frame and a second half-frame, each comprising a plurality of arcuate sections connected by longitudinal sections; and
a plurality of connecting segments securing a plurality of first half-frame longitudinal sections to a plurality of second half-frame longitudinal sections such that the first half-frame and the second half-frame form a cylinder.

Abstract
A stent includes a cylindrical frame and a plurality of connecting segments connecting opposed portions of the frame. The frame may be formed from either of a single loop of resilient wire formed into a series of arcuate sections and longitudinal connecting sections, two pieces of resilient wire each formed into a half-frame having a series of arcuate sections and longitudinal connecting sections or from a piece of laser cut hypotubing. For the resilient wire frames, the connecting segments may be either of a single metal or plastic band wrapped around opposed longitudinal sections, joined individual bands wrapped around opposed longitudinal sections, or a piece of solder joining opposed longitudinal sections. For the hypotubing frame, the connecting segments are pieces of remaining hypotubing joining opposed longitudinal sections.

19. A stent for use in the intravascular treatment of blood vessels, comprising:
-
a first half-frame and a second half-frame, each comprising a plurality of arcuate loop sections which comprise a pair of arcuate sections connected at each end by a longitudinal connecting section; and
a plurality of connecting segments securing a plurality of first half-frame arcuate loop sections to a plurality of second half-frame arcuate loop sections such that the first half-frame and the second half-frame form a cylinder.

28. A stent for use in the intravascular treatment of blood vessels, comprising:
-
a generally cylindrical frame formed of an elongate resilient wire, the two free ends of the wire extending distally from the proximal end of the frame, thereafter transitioning at a first point to a pair of opposed first arcuate sections, thereafter transitioning to a pair of opposed first longitudinal sections for a length to a second point, thereafter transitioning to a pair of opposed second arcuate sections and a pair of opposed second longitudinal sections and proceeding in a like pattern to the distal end of the frame; and
a plurality of connecting segments, connecting a plurality of opposed longitudinal sections.
