摘要： A strut assembly to be used in conjunction with an embolic filtering device has varying strut thicknesses, with the thickness selected based at least in part on the flexing characteristics of the particular portion of the strut assembly. The strut assembly is formed with patterns having flexing portions and stable portions, with the flexing portions contributing to the flexibility of the strut assembly during delivery and recovery in the patient's vasculature. The stable portions remain relatively unflexed and stiff when being delivered or recovered from the patient's vasculature. The stable portions provide strength and increased radiopacity to the strut assembly which is needed when the strut assembly is deployed in the body vessel. The flexing portions act much like a mechanical hinges in providing the needed flexibility to resiliently bend when being delivered through tortuous anatomy of the patient.

摘要： A ratcheting handle actuator provides for a tool to actuate an intraluminal catheter system for treatment at an intraluminal site by repeated movements of the handle. This allows for actuation over a greater distance than a physician might be able to perform in a single motion while preserving a direct correspondence between the movements of the ratcheting handle and the actuation of the intraluminal device.

摘要： A catheter assembly is provided having an inner member and an outer member extending along a longitudinal axis, the inner member and the outer member having a coaxial configuration and dimensioned for relative axial movement. The outer member has a wall defining an opening such as a longitudinal slot; an expanding member such as a leaf spring is connected to the inner member, the leaf spring being adapted to engage with the longitudinal slot so as to maintain rotational alignment between inner member and outer member.

摘要： An embolic protection device for use in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filtering assembly having a self-expanding strut assembly and a filter element attached thereto. In one embodiment, the filtering assembly is attached to the distal end of a guide wire and is deployed within the patient's vasculature as the guide wire is manipulated into the area of treatment. A restraining sheath placed over the filtering assembly in a coaxial arrangement maintains the filtering assembly in its collapsed position until it is ready to be deployed by the physician. Thereafter, the sheath can be retracted to expose the filtering assembly which will then self-expand within the patient's vasculature. Interventional devices can be delivered over the guide wire and any embolic debris created during the interventional procedure and released into the blood stream will enter the filtering assembly and be captured therein. Other embodiments include filtering assemblies attached to an outer tubular member and inner shaft member which apply axial force to the distal ends of the assembly to either expand or contract the struts as needed.

摘要： A strut assembly to be used in conjunction with an embolic filtering device has varying strut thicknesses, with the thickness selected based at least in part on the flexing characteristics of the particular portion of the strut assembly. The strut assembly is formed with patterns having flexing portions and stable portions, with the flexing portions contributing to the flexibility of the strut assembly during delivery and recovery in the patient's vasculature. The stable portions remain relatively unflexed and stiff when being delivered or recovered from the patient's vasculature. The stable portions provide strength and increased radiopacity to the strut assembly which is needed when the strut assembly is deployed in the body vessel. The flexing portions act much like a mechanical hinges in providing the needed flexibility to resiliently bend when being delivered through tortuous anatomy of the patient.

摘要： Stent designs for use in peripheral vessels, such as the carotid arteries, are disclosed. The stents consist of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so that the stent is flexible in a longitudinal direction. The cylindrical elements are generally serpentine wave pattern transverse to the longitudinal axis between alternating valley portion and peak portions, the valley portion including alternating double-curved portions and U-shaped portions. The interconnecting members are attached to the double-curved portions to connect a cylindrical element to an adjacent cylindrical element and interconnecting members are attached to the U-shaped portions to connect the cylindrical element to the other adjacent cylindrical element. The designs include an eight crown and six crown stent which exhibit flexibility and sufficient radial strength to support the vessel.
