  • Publication number: 20070027521
    Abstract: Apparatus for delivering stents to body lumens include one or more tubular prostheses carried at the distal end of a catheter shaft, a sheath slidably disposed over the prostheses, and a guidewire tube extending from within the sheath to the exterior of the sheath through an exit port in a sidewall thereof. A guidewire extends slidably through the guidewire tube. The sheath can be moved relative to the catheter shaft and the guidewire tube to expose the prostheses for deployment. Methods of delivering stents are also provided.

  • Publication number: 20050149159
    Abstract: Devices and methods are provided for controlling and indicating the deployed length of an interventional element on an interventional catheter. The interventional element may be a stent or series of stents, a balloon, or any other interventional element for which length control is necessary or desirable. Devices for controlling the length of the interventional element include gear driven actuators, motors, and other mechanisms. Devices for indicating length of an interventional element to the user include sensors, detents, visual displays and other mechanisms providing visual, audible, and tangible indications of length to the user. The control and indication devices preferably work in tandem to enable highly precise adjustment of interventional element length.

  • Publication number: 20050080475
    Abstract: Stent delivery devices and methods include a shuttle for carrying multiple stent segments, to avoid direct contact between the stent segments and an expandable member. A sheath is disposed over the expandable member such that when it is withdrawn, a distal portion of the expandable member is exposed to expand against the shuttle, thus expanding the shuttle and expanding and deploying a selected number of stent segments. To deploy a second selected number of stent segments, the sheath may be withdrawn further to expose more of the expandable member. Thus, one or more custom length stents may be deployed with a reduced risk of damage to the expandable member and the stent segments and enhanced ease and accuracy of stent placement at a treatment location.

  • Publication number: 20050049673
    Abstract: Blood vessels and other body lumens are expanded using an evertible braided prosthesis. The braided prosthesis is delivered to the blood vessel in a radially collapsed configuration. A leading edge of the braided prosthesis is then everted so that it expands as it is advanced through the blood vessel. Optionally, the prosthesis can be provided with a biologically active substance in order to inhibit hyperplasia or have other desired biological effects.

  • Publication number: 20040093061
    Abstract: Delivery catheters and systems are adapted for delivering multiple discreet prostheses in body lumens. An exemplary delivery catheter comprises a sheath, a pusher for moving the prostheses relative to the sheath, and a valve member for selectively retaining the prostheses in the sheath. For balloon expandable stents, an elongated shaft and an expandable member are slidably disposed in the sheath, and the prostheses are positionable on the expandable member for deployment in the body lumen. The valve member allows a selected number of prostheses to be deployed from the sheath while retaining other prostheses within the sheath.
