    摘要： A stent delivery catheter comprising a stiff proximal shaft, a manifold, a distal shaft, a pull back stent release assembly and a pull back wire and a guide wire, both extending through the catheter from the manifold to the distal end of the catheter. The proximal shaft encloses a pull back wire shaft and a guide wire shaft. The proximal shaft may be made of an extruded polymer having two lumens disposed therein to receive the separate wires, keeping them separate.

    摘要： A prosthesis for implanting in a patient may include an elongated, laterally flexible structure having first and second end portions that are spaced from one another along a length of the elongated structure. First and second magnetic structures may be respectively secured to the first and second end portions. The first and second magnetic structures may magnetically attract one another when brought into proximity with one another. This magnetic attraction can facilitate achieving desired final relative positioning and/or alignment of the magnetic structures. Thereafter, this magnetic attraction can keep (or help to keep) the end portions of the prosthesis proximate to one another, thereby forming the prosthesis into a desired closed ring shape.

    摘要： The present invention is a vascular stent comprising a cylindrical wall radially expandable from a compressed state to an expanded state and including a plurality of cells. At least one cell includes a first primary member having a first restrainer member and a second primary member having a second restrainer member. When the cylindrical wall is in the expanded state, the first and second primary members are located a greater distance from each other than when the cylindrical wall is in the compressed state. The first and second restrainer members join to maintain the cylindrical wall in the compressed state. An expansion force applied to the cylindrical wall causes the first and second restrainer members to separate, thereby freeing the cylindrical wall to expand from the compressed state to the expanded state.

    摘要： A stent delivery system which has a catheter including an inflatable portion. A stent being disposed about the inflatable portion of the catheter, the stent having a contracted state and an expanded state. A pair of stent retaining sleeves which are partially composed of PTFE, each sleeve having a first end portion overlying a respective end of the stent, each sleeve having a second end portion respectively attached to the catheter, the sleeves retaining the stent to the catheter when the stent is in the contracted state, the stent being freed from the sleeves when the stent is placed in the expanded state. The sleeves being placed on the stent by heat shrinking. The inflatable portion of the balloon optionally having stepped compliant characteristics.
