ABSTRACT:

FIELD OF THE INVENTION
The present invention is in the field of surgical implements, more particularly in the field of stents.
BACKGROUND OF THE INVENTION
The present invention relates to cardiovascular stents which can be inserted into a body lumen. More particularly, the present invention relates to a removable cardiovascular stent designed to operate with an extraction catheter to enable easy retrieval of the implanted stent.
A stent is typically a tubular metallic or polymeric body, which is carried on a dilation catheter to a specific vascular location. In one cardiovascular application, a stent is mounted on a balloon catheter and positioned at the appropriate site within an artery. The balloon is thereafter deflated and removed, leaving the expanded stent in place in the artery. The stent may also be self or thermally expanding, thus not requiring a balloon for placement. The arterial wall is supported by the stent and prevented from collapsing.
SUMMARY OF THE INVENTION
The present invention is a stent delivery system comprising a stent the girth of which expands upon longitudinal compression, a pair of telescoping tubes where the inner tube has a greater length than the outer tube, and the stent surrounds the inner tube, a distal deployment strut fixedly connected at one end to the inner tube, and at the other end non-fixedly connected to the stent, a proximal deployment strut fixedly connected at one end to the outer tube, and at the other end non-fixedly connected to the stent, and an anchoring barb at the distal end of the stent.
Therefore, it is an object of the present invention to provide a stent which is manually expandable, rather than balloon-expandable or self-expandable.
It is a further object of the invention to provide a stent which can be placed accurately within a vessel.
It is a further object of the present invention to provide a stent which has no balloon present to occlude visualization of the vessel lumen during deployment.
