    摘要: Wire-guided interventional devices and methods are provided which enable faster and easier catheter exchanges. The interventional devices include a catheter shaft and a guidewire tube wherein the catheter shaft and the guidewire tube each have a length sufficient to extend to the vascular penetration when the interventional device is positioned at the treatment site. In some embodiments, a collar is disposed around the catheter shaft and guidewire tube that automatically inserts or removes the guidewire from the guidewire tube or automatically collapses or extends the guidewire tube as the catheter is introduced or withdrawn.

    摘要: Apparatus and methods for delivering stents to bifurcated vessels involve delivering a first stent in a main branch of a vessel using a stent delivery catheter and delivering a second stent in a side branch of the vessel, without removing the stent delivery catheter from the patient. In various embodiments, multiple stents may be placed in either or both of the main and side branches. In some embodiments, stents in main and side branches are separate and do not touch, while in other embodiments a side branch stent may extend through a sidewall opening in a main branch stent. Stent length may optionally be adjusted in situ, and some embodiments provide for predilatation of one or more lesions.
