Medical device for intraluminal endovascular stenting

A medical device comprising:

• a catheter and a stent mounted on the catheter, the stent comprising
• a hollow, cylindrical body comprised of a first ring and a second ring, the first and the second rings each extending circumferentially around the cylindrical body, the first and second rings each including an undulating series of peaks and valleys;
• a first inflection point on the first ring, the first inflection point disposed on a portion of the first ring which extends between an adjacent peak and valley;
• a second inflection point on the second ring, the second inflection point disposed on a portion of the second ring which extends between an adjacent peak and valley;
• a link joined at a first end at the first inflection point on the first ring and at a second end at the second inflection point whereby the first and second rings are joined together;
• the stent crimped on the catheter such that the link nests near the first end within the undulations of the first ring and also nests near the second end within the undulations of the second ring.

• a hollow, cylindrical body comprised of a first ring and a second ring, the first and the second rings each extending circumferentially around the cylindrical body, the first and second rings each including an undulating series of peaks and valleys;
• a first inflection point on the first ring, the first inflection point disposed on a portion of the first ring which extends between an adjacent peak and valley;
• a second inflection point on the second ring, the second inflection point disposed on a portion of the second ring which extends between an adjacent peak and valley;
• a link joined at a first end at the first inflection point on the first ring and at a second end at the second inflection point whereby the first and second rings are joined together;
• the stent crimped on the catheter such that the stent can flex near the first and second inflection points without significant radial expansion as the stent is subjected to bending along a longitudinal axis as it is advanced through bends in a coronary artery.

A medical device comprising:

• a catheter and a stent mounted on the catheter, the stent comprising
• a hollow, cylindrical body comprised of a first ring and a second ring, the first and the second rings each extending circumferentially around the cylindrical body, the first and second rings each including an undulating series of peaks and valleys, wherein the undulating peaks and valleys of the first ring are arranged with the undulating peaks and valleys of the second ring such that the first and second rings have peaks and valleys which are paired with each other in an in-phase relationship;
• a link joined at a first end at a point on the first ring which is substantially centered between a peak and a valley and at a second end at a point on the second ring which is substantially centered between a peak and a valley;
• the stent crimped on the catheter such that the link nests near the first end within the undulations of the first ring and also nests near the second end within the undulations of the second ring.

• a hollow, cylindrical body comprised of a first ring and a second ring, the first and the second rings each extending circumferentially around the cylindrical body, the first and second rings each including an undulating series of peaks and valleys, the peaks and valleys of the first ring forming a first amplitude and the peaks and valleys of the second ring forming a second amplitude which is smaller than the first amplitude;
• a first point on the first ring, the first point disposed on a portion of the first ring which extends between an adjacent peak and valley;
• a point on the second ring, the second point disposed on a portion of the second ring which extends between an adjacent peak and valley;
• a link joined at a first end at the first point on the first ring and at a second end at the second point whereby the first and second rings are joined together.

A medical device comprising:

• a catheter and a stent mounted on the catheter, the stent comprising
• a hollow, cylindrical body comprised of a ring, the ring extending circumferentially around the cylindrical body, the ring including an undulating series of peaks and valleys;
• a flat, radiopaque marker joined to the first ring and substantially centered between a peak and a valley;
• the stent crimped on the catheter such that the radiopaque marker nests within the undulations of the first ring and also nests near the second end within the undulations of the second ring.
