    摘要： A balloon catheter is provided having an expandable distal portion and balloon protector means comprising a first removable sleeve having a variable inner diameter to ease sliding the first sleeve over the balloon, and an optional second removable (outer) sleeve positioned over the inner sleeve, the second (outer) sleeve having a constrictive relationship with the first (inner) sleeve, said first and second sleeves being removed prior to use of the catheter. A stent delivery system is provided to facilitate introduction and placement of a stent, and includes a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state, said distal portion further comprising a balloon and at least one dam over which the balloon extends, and a stent positioned around the distal portion of the catheter around the balloon or gripper linear control device, said stent having a contracted condition, being sized in the contracted condition to closely surround the balloon in the contracted state, and being expandable to an expanded condition; a first removable (inner) sleeve in the region of the distal portion of the catheter positioned around the stent (and between the damns where the device comprises two dams), said first sleeve comprising a first end, a second end and a variable inner diameter to ease sliding the sleeve over the balloon and stent; an optional second removable (outer) sleeve positioned over the stent, first sleeve and at least one dam, said second (outer) sleeve having a constrictive relationship with the first (inner) sleeve, whereby when compressed by the outer sleeve, the inner sleeve will have an inner diameter approximately equal to or less than the outer profile of the collapsed balloon over the at least one dam, said first and second sleeves being removed prior to use of the stent delivery system and release of the stent by expansion of the balloon.

    摘要： A catheter assembly comprises a catheter shaft having a first region and a second region. The first region is less radiopaque than the second region. The first region is constructed of a shaft material and the second region is constructed from the shaft material in combination with at least one radiopaque material. At least a portion of the shaft material of the second region defines at least one grooved region. The at least one radiopaque material is positioned at least partially within the at least one grooved region.

    摘要： An improved deployment system deploys a stent to maintain the patency of a dilated vessel. The improved stent deployment system is adapted for deployment with a balloon catheter. The stent deployment system includes an expandable stent sheath for supporting the stent for deployment. The stent sheath is movably coupled to a catheter shaft and is relatively short in comparison to the catheter shaft. The stent sheath is movably coupled to the catheter shaft for movement between a retracted position and an advanced deployment position aligned with the balloon for expansion via the balloon for deployment of the stent supported thereby.
